Display Blocks are a response to two major limitations of current displays: visualization and interaction. Each device consist of six organic light emitting diode screens, arranged in a cubic form factor. I explore the possibilities that this type of display holds for data visualization, manipulation and exploration. To this end, I also propose a series of accompanying applications that leverage the design of the displays. To begin assessing the potential of this platform and to define future directions in which to expand this research, I report on a series of interviews I conducted regarding the potential of Display Blocks with relevant technologists, interaction designers, data visualizers and educators. The work encompassed in this thesis shows the promise of display technologies which use their form factor as a cue to understanding their content.<br>by Pol Pla i Conesa.<br>S.M.

Dans le contexte de l'imagerie couleur, cette thèse se focalise sur la caractérisation colorimétrique des moniteurs, vidéo-projecteurs et systèmes multi-projecteurs. A partir de l'approche traditionnelle ponctuelle, nous continuons avec une analyse spatiale. Nous portons attention à la dualité entre une caractérisation à objectif professionnel visant à garantir la précision colorimétrique et une caractérisation "commerciale" visant à préserver le sens et l'esthétisme du contenu. Dans une première partie, nous considérons l'approche ponctuelle. Nous étudions le modèle piecewise linear assuming variation in chromaticity et démontrons son efficacité sur les dispositifs à cristaux liquides. Nous évaluons et améliorons une méthode "commerciale" ne nécessitant pas l'usage d'un appareil de mesure autre qu'un appareil de photo numérique. Nous travaillons également sur la distribution des données dans les espaces colorimétriques pour la construction de look up table.

Starting from the conventional pointwise approach, we continue to some spatial analysis. We give some special attention to the duality between a professional and a consumer-oriented characterization. In the first part of this thesis we consider pointwise display color characterization. We investigate the piecewise linear assuming variation in chromaticity and demonstrate its efficiency on liquid crystal technology. We evaluate and improve a end-user method that does not need any measurement device other than a simple digital color camera. We confirm that this method gives significantly better results than using default gamma settings for both liquid crystal and digital light processing projection displays. We focus on the distribution of color patches in color spaces for the establishment of 3d look up table models. We propose a new accurate display color characterization model based on polyharmonic spline interpolation/approximation. We propose methods to build an optimized structure that permits to invert any display color characterization forward model. In a second part, we establish a basis for spatial color characterization via the quantitative analysis of the color shift and its spatial variation thoughout the display area. We show that the spatial chromaticity shift is not negligible in some cases and that some features are spatially invariant within one display of a given technology

Full textAbstract:
This present study sought to evaluate the effectiveness of two types of school
library displays: a display with books only, called Display, and a display with books,
posters, models, copy, and realia, called Display +. The effectiveness of these displays
was to be measured in two ways: a) through the observation of the attaction power,
holding power and viewer participation in a display and b) through measuring the
circulation of displayed books.
Before commencing the study a literature search was conducted. The result of the
literature search yielded four authors, Goldhor (1972; 1981), Aguilar (1983), Watson
(1985), and Baker (1986), who had researched the relationship between circulation and
displays. Each of these studies used the measurable effect of circulation increasing,
decreasing or remaining constant to determine the effect of the display. This present study
used a similar methodology and monitored the circulation of books on both types of
displays. However, this study sought to go beyond the effect of circulation in determining
the effectiveness of displays because the previous studies had not taken into account the
library user who is affected by the display but is unable to borrow a book from the
display. The literature search turned towards the area of museum exhibits and displays
and the methodology employed to evaluate these exhibits and displays. Shettel (1968),
Warren (1972), Screven (1976), Linn (1976), Clowes and Wolfe (1980), and Miles
(1982) used attraction and holding power as measures of museum exhibit and display
effectiveness. Similarly, library users can be attracted and their attention held by library
displays. To the variables of attraction and holding power this study added the variable of
participation, picking up books or other items in the display not necessarily with the intent
of borrowing the books. In order to construct a Display + and control as far as possible
the elements in the display a literature search of books and articles relating to the design
elements of displays was conducted, and findings applied in the construction of the
display.
Shettel's (1968) methodology of unobtrusive observation was employed in this
study with the added benefit of videotaping the observations. The hypotheses were set out
in three groups, those relating to a single display, those comparing the effectiveness of
Display and Display +, and those relating to circulation.
The results of this study found in general that the attraction power of Display +
exceeded the attraction power of Display but the holding power and participation in
Display was greater than that of Display + indicating that the designer of library displays
should pay particular attention to the purpose of displays in their libraries. The results of
the circulation hypothesis confirmed the results of Goldhor (1972;1981), Aguilar (1983),
Watson (1985), and Baker (1986) that more books circulated when they were displayed
than when they were on the library shelves.

McElhaney, Steven Hunt. "Defining display complexity in electric utility system operator displays." Thesis, Mississippi State University, 2014. http://pqdtopen.proquest.com/#viewpdf?dispub=3603464.
Full textAbstract:
<p> In the electric utility industry, displays provide power system operators with information on and the status of the system, who then make decisions on how to maintain the safety, the reliability and the efficient operation of the utility generation and transmission grid based on that information. Complexity of the data presented and the display itself can lead to errors or misjudgments that can cause power system operators to make unwise decisions. The primary goal of this research was to develop a method to quantify display complexity for select displays used by system operators when operating the electric generation and transmission grids. Three studies were performed: (1) complexity measure development, (2) validation of the measure using usability and situation awareness (SA) techniques, and (3) display revisions based on complexity measure findings. Fifteen 15 different complexity metrics were originally considered (additive models, multiplicative models, and combination models with five different weighting schemes). The additive model with equal weighting was found to be the most sensitive in differentiating displays and was used in the later studies. For the validation study, system operators were asked to complete a usability questionnaire and a paper-based SA test using the current displays. Correlation and scatter plot analyses was used to determine if the complexity metric and usability and SA scores were related. Results of the validation study indicated that usability and SA scores for the studied displays were not well correlated with the complexity metric. In study 3, the highest and lowest scoring displays were redesigned with an emphasis on maintaining functionality but reducing aspects of complexity that were driving the complexity score. Systems operators again completed the usability and SA testing using the redesigned displays and again correlation analysis was performed. As was the case with study 2, usability scores were not correlated with the complexity metric; however, SA scores were significantly correlated. The complexity metric developed here can be used to quantify the complexity in a display and identify redesign opportunities to reduce non-essential information, as displays that are less complex should result in improved operator performance and satisfaction with the display.</p>

Much significance and symbolism is imbued in such a thin layer and I am actively aware of this as I work. The way I construct and render my subjects and the space in which they reside determines how they are viewed, perceived, considered, and judged by others.

Thesis (Ph.D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, February 1999.<br>"January 1999."<br>Includes bibliographical references (leaves 66-67).<br>We present techniques for combining high-performance computing with feedback to enable the correction of imperfections in the alignment, optical system, and fabrication of very high-resolution display devices. The key idea relies on the measurement of relative alignment, rotation, optical distortion, and intensity gradients of an aggregated set of low-cost image display devices using a precision low cost reference. Use of the reference allows the construction of a locally correct map relating the coordinate system of the aggregate display to the coordinate systems of the individual projectors composing the display. This idea provides a new technology for linearly scalable, bright, seamless, high-resolution large-scale self-calibrating displays (seamless video walls). Such a large-scale display was constructed using the techniques described in this dissertation. Low-cost computation coupled with feedback is used to provide the precision necessary to create these displays. Digital photogrammetry and digital image warping techniques are used to make a single seamless image appear across the aggregated projection displays. The following techniques are used to improve the display quality: ** Anti-alias filtering to improve the display of high frequency in images; ** Limiting the range of displayed intensities to ones that can be displayed uniformly across all the projectors; and ** Applying intensity smoothing functions to the regions of the image that are projected in the overlapping region. These functions smoothly and gradually transition the projection among the projectors. The resultant systems demonstrate the viability of the approach by succeeding where other approaches have failed; it makes huge seamless video walls a reality.<br>by Rajeev J. Surati.<br>Ph.D.

Full textAbstract:
Mobile devices equipped with features (e.g., camera, network connectivity and media player) are increasingly being used for different tasks such as web browsing, document reading and photography. While the portability of mobile devices makes them desirable for pervasive access to information, their small screen real-estate often imposes restrictions on the amount of information that can be displayed and manipulated on them. On the other hand, large displays have become commonplace in many outdoor as well as indoor environments. While they provide an efficient way of presenting and disseminating information, they provide little support for digital interactivity or physical accessibility. Researchers argue that mobile phones provide an efficient and portable way of interacting with large displays, and the latter can overcome the limitations of the small screens of mobile devices by providing a larger presentation and interaction space. However, distributing user interface (UI) elements across a mobile device and a large display can cause switching of visual attention and that may affect task performance. This thesis specifically explores how the switching of visual attention across a handheld mobile device and a vertical large display can affect a single user's task performance during mobile interaction with large displays. It introduces a taxonomy based on the factors associated with the visual arrangement of Multi Display User Interfaces (MDUIs) that can influence visual attention switching during interaction with MDUIs. It presents an empirical analysis of the effects of different distributions of input and output across mobile and large displays on the user's task performance, subjective workload and preference in the multiple-widget selection task, and in visual search tasks with maps, texts and photos. Experimental results show that the selection of multiple widgets replicated on the mobile device as well as on the large display, versus those shown only on the large display, is faster despite the cost of initial attention switching in the former. On the other hand, a hybrid UI configuration where the visual output is distributed across the mobile and large displays is the worst, or equivalent to the worst, configuration in all the visual search tasks. A mobile device-controlled large display configuration performs best in the map search task and equal to best (i.e., tied with a mobile-only configuration) in text- and photo-search tasks.

A Display Computer (DC) is an everyday object: Display Computer = Display +
Computer. The ÂDisplay part is the standard viewing surface found on everyday
objects that conveys information or art. The ÂComputer is found on the same everyday
object; but by its ubiquitous nature, it will be relatively unnoticeable by the DC user, as
it is manufactured Âin the marginsÂ. A DC may be mobile, moving with us as part of the
everyday object we are using. DCs will be ubiquitous: Âeffectively invisibleÂ, available
at a glance, and seamlessly integrated into the environment. A DC should be an example
of WeiserÂs calm technology: encalming to the user, providing peripheral awareness
without information overload. A DC should provide unremarkable computing in support
of our daily routines in life. The nbaCub (nightly bedtime ambient Cues utility buddy)
prototype illustrates a sample application of how DCs can be useful in the everyday
environment of the home of the future. Embedding a computer into a toy, such that the
display is the only visible portion, can present many opportunities for seamless and nontraditional
uses of computing technology for our youngest user community. A field
study was conducted in the home environment of a five-year old child over ten
consecutive weeks as an informal, proof of concept of what Display Computers for
children can look like and be used for in the near future. The personalized nbaCub
provided lightweight, ambient information during the necessary daily routines of
preparing for bed (evening routine) and preparing to go to school (morning routine). To
further understand the childÂs progress towards learning abstract concepts of time
passage and routines, a novel Âtest by design activity was included. Here, the role of
the subject changed to primary designer/director. Final post-testing showed the subject knew both morning and bedtime routines very well and correctly answered seven of
eight questions based on abstract images of time passage. Thus, the subject was in the
process of learning the more abstract concept of time passage, but was not totally
comfortable with the idea at the end of the study.

Detta examensarbete avser att höja kunskapen inom displaymätningar och utveckla mer objektiva testmetoder. I den här rapporten tas flera mätparametrar upp. Dock är det inte nödvändigt att optimera alla dessa för att en display ska upplevas bra. Därför är det viktigt att utvärdera displayen efter sitt användningsområde och i vilken miljö den ska användas i . En svårighet med displayjämförelser är hur hjärnan tolkar det ögat ser. Ögats olinjära egenskaper gör det heller inte lättare. För att optimera eller veta vad man ska mäta på en display är det därför viktigt att känna till hur ögat fungerar. Därför beskrivs ögats uppbyggnad och matematiska formler introduceras för att beskriva hur ögat beter sig. Subjektiva upplösningsmätningar är något som vill frångå för att de varierar mycket för olika personer, vilket innebär att resultaten inte kan jämföras rakt av. Målet är att få en mer objektiv metod och därför introduceras en modell för det mänskliga ögat. Ögonmodellen utvärderas med subjektiva avläsningar både på display och verkliga mål där resultatet blir mycket bra.

Full textAbstract:
A volumetric display device is a graphical display device that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects. One definition offered by pioneers in the field is that volumetric displays create 3D imagery via the emission, scattering, or relaying of illumination from well-defined regions in (x,y,z) space. Though there is no consensus among researchers in the field, it may be reasonable to admit holographic and highly multiview displays to the volumetric display family if they do a reasonable job of projecting a three-dimensional light field within a volume.

Full textAbstract:
Holoscopic 3D imaging “Integral imaging” was first proposed by Lippmann in 1908. It has become an attractive technique for creating full colour 3D scene that exists in space. It promotes a single camera aperture for recording spatial information of a real scene and it uses a regularly spaced microlens arrays to simulate the principle of Fly’s eye technique, which creates physical duplicates of light field “true 3D-imaging technique”. While stereoscopic and multiview 3D imaging systems which simulate human eye technique are widely available in the commercial market, holoscopic 3D imaging technology is still in the research phase. The aim of this research is to investigate spatial resolution of holoscopic 3D imaging and display technology, which includes holoscopic 3D camera, processing and display. Smart microlens array architecture is proposed that doubles spatial resolution of holoscopic 3D camera horizontally by trading horizontal and vertical resolutions. In particular, it overcomes unbalanced pixel aspect ratio of unidirectional holoscopic 3D images. In addition, omnidirectional holoscopic 3D computer graphics rendering techniques are proposed that simplify the rendering complexity and facilitate holoscopic 3D content generation. Holoscopic 3D image stitching algorithm is proposed that widens overall viewing angle of holoscopic 3D camera aperture and pre-processing of holoscopic 3D image filters are proposed for spatial data alignment and 3D image data processing. In addition, Dynamic hyperlinker tool is developed that offers interactive holoscopic 3D video content search-ability and browse-ability. Novel pixel mapping techniques are proposed that improves spatial resolution and visual definition in space. For instance, 4D-DSPM enhances 3D pixels per inch from 44 3D-PPIs to 176 3D-PPIs horizontally and achieves spatial resolution of 1365 × 384 3D-Pixels whereas the traditional spatial resolution is 341 × 1536 3D-Pixels. In addition distributed pixel mapping is proposed that improves quality of holoscopic 3D scene in space by creating RGB-colour channel elemental images.

Full textAbstract:
This thesis describes the novel use of an electrolytic capacitor to controllably modulate the optical properties of a surface. The electrically-controlled modulation is achieved using electrodes comprised of carbon nanofoam, a new allotrope of carbon that has an extremely high surface to volume ratio, resulting in a very high capacitance per unit volume which enables the material to attract a significant amount of electrostatic charge, an amount that is much greater than would be the case if the electrodes were not so highly porous.
In the display described here, a diffusely reflective porous material, positioned above an interdigital array formed by two carbon nanofoam electrodes, was immersed in an electrolyte solution in which light-absorbing dye ions had been dissolved. When an electrical potential was applied across the electrodes, the capacitor charged and the dye ions were drawn into the pores of the electrodes and therefore drawn out of the bulk solution and porous material, causing the material to become reflective rather than colored. When the applied voltage was removed, the dye ions were able to diffuse out of the nanofoam and redistribute throughout the bulk solution and into the material, causing it to return to its original colored appearance. This effect was shown to be reproducible over many cycles and various experiments were conducted to develop a better understanding of the interaction of the dye ions with the carbon nanofoam electrodes and to understand how these interactions affect the time-course of the response.
Potential applications of this technology include low power, high-contrast reflective image display devices, particularly in applications where the visual appearance of ink on paper is required. These so-called “electronic paper” displays are becoming more common in devices such as e-book readers, but the displays that are currently used in these devices are limited in terms of brightness and switching speed. The results of this research indicate that this approach using high capacitance porous electrodes may have application in high contrast reflective display devices.

The fact that a seller has the opportunity to download this applicationin a mobile device gives the seller a very good tool to help the customers. This is because the seller does not have to go to a fixed computer to check productinformation, such as stock balance, but it is directly in the mobile device.The result of this is that the customer gets a better experience with the seller, and that the seller can work more effciently.<br>Detta examensarbete omfattar utvecklingen av en applikation.

This thesis investigates the various concepts of failsafe display, and the means to achieve them. It also investigates the wide range of display technologies available and their suitability for use in a failsafe display. The LED, together with monitoring circuitry, emerges as the most suitable for the application.

Full textAbstract:
There are many different techniques to display 3D information. However, not many of them are able to provide sufficient depth cues to the observers to sense or feel the images as real three-dimensional objects. Volumetric three-dimensional displays generate images within a real 3D space, so they provide most of the depth cues automatically. This thesis discusses the basic notions required to understand three-dimensional displays. Also discussed are different techniques used to display 3D information and their advantages and disadvantages as well as their current limitations. Several rare-earth doped fluoride crystals that are excited to emit visible light by sequential two photon absorption have been investigated as display medium candidates for static volumetric three dimensional displays. A scalable display medium is suggested to enable large 3D displays. This medium is a dispersion of particles of the rare earth doped fluoride crystals in a refractive index-matched polymer matrix. Detailed experiments are described to prepare such a scalable display medium using a wide variety of polymers. The scattering problem in such a medium was greatly reduced by index-matching the polymer to the crystalline particles. An index-matching condition that optimizes the performance was identified and demonstrated. A potential near-future solution is demonstrated and improvements are suggested.<br>Ph.D.<br>Optics and Photonics<br>Optics and Photonics<br>Optics PhD

In der vorliegenden Arbeit werden die im Zusammenhang mit der Strahlablenkung stehenden Systemaspekte der auf MEMS-Scanner basierenden Laser-Display-Technologie theoretisch analysiert und aus den Ergebnissen die praktische Implementierung eines Laser-Display-Systems als Testplattform vorgenommen. Dabei werden mit einem Ansatz auf Basis zweier 1D-Scanner und einem weiteren Ansatz mit einem 2D-Scanner zwei Varianten realisiert. Darüber hinaus erfolgt die Entwicklung eines bildbasierten Multiparametertestverfahrens, welches sowohl für den Test komplettierter Strahlablenkeinheiten bzw. Projektionsmodule als auch zum umfassenden und zeiteffizienten Test von MEMS-Scannern auf Wafer-Level geeignet ist. Mit diesem Verfahren erfolgt eine Charakterisierung der zwei realisierten Varianten des Laser-Displays.
Ausgehend von den Eigenschaften des menschlichen visuellen Systems und den daraus resultierenden Anforderungen an das Bild sowie einer systemtheoretischen Betrachtung des mechanischen Verhaltens von MEMS-Scannern bildet die Ansteuersignalerzeugung für den resonanten Betrieb der schnellen und den quasistatischen Betrieb der langsamen Achse einen Schwerpunkt. Neben dem reinen digitalen Regler- bzw. Filterentwurf sowie mehreren Linearisierungsmaßnahmen beinhaltet dieser auch die Herleitung einer FPGA-basierten Videosignalverarbeitung zur Konvertierung von Scannpattern, Zeitregime und Auflösung mit einer entsprechenden Synchronisierung von Strahlablenkung und Lasermodulation. Auf Grundlage der daraus resultierenden Erkenntnisse über den Zusammenhang zwischen Scanner-/Systemparametern und Bildparametern werden Testbild-Bildverarbeitungsalgorithmus-Kombinationen entwickelt und diese, angeordnet in einer Sequenz, mit einem Kalibrierverfahren zu einem Testverfahren für MEMS-Scanner vervollständigt.
Die Ergebnisse dieser Arbeit entstanden im Rahmen von industriell beauftragten F&E-Projekten und fließen in die andauernde Fortführung des Themas beim Auftraggeber ein.

Full textAbstract:
Display and function are a pair of conflicting concepts. The thesis focuses on displaying a sequence of functional spaces which are commonly not exposed to the eyes of the public, in this case, a general aviation airport. The greatest challenge over the course of the study was how to create displayable spaces without overlooking basic functional programs and deepen both concepts in the process.
The airport is designed to fulfill the dual attributes of display and function. It is an aircraft museum, displaying the behind-the-scenes system from arriving, to maintaining, to towing, to parking, and to departing. As well, it is a fully-functional airport, consisting of a sequence of functional spaces, including: runway, taxi area, maintenance hangar, towing corridor, parking spots, and auxiliary spaces.
In the context of the thesis, "display" means to expose the elements - aircraft and air travel - as an exhibit to be viewed or to be noticed by the public through spatial organization and scales of engagement.<br>Master of Architecture

Full textAbstract:
Includes bibliography.<br>The thesis deals with graphical display techniques based on the singular value decomposition. These techniques, known as biplots, are used to find low dimensional representations of multidimensional data matrices. The aim of the thesis is to provide a review of biplots for a practical statistician who is not familiar with the area. It therefore focuses on the underlying theory, assuming a standard statisticians' knowledge of matrix algebra, and on the interpretation of the various plots. The topic falls in the realm of descriptive statistics. As such, the methods are chiefly exploratory. They are a means of summarising the data. The data matrix is represented in a reduced number of dimensions, usually two, for simplicity of display. The aim is to summarise the information in the matrix and to present a visual representation of this information. The aim in using graphical display techniques is that the "gain in interpretability far exceeds the loss in information" (Greenacre, 1984). A graphical description is often more easy to understand than a numerical one. Histograms and pie charts are familiar forms of data representation to many people with no other, or very rudimentary, statistical understanding. These are applicable to univariate data. For multivariate data sets, univariate methods do not reveal interesting relationships in the data set as a whole. In addition, a biplot can be presented in a manner which can be readily understood by non-statistically minded individuals. Greenacre (1984) comments that only in recent years has the value of statistical graphics been recognised. Young (1989) notes that recently there has been a shift in emphasis, among statisticians towards exploratory data analysis methods. This school of thought was given momentum by the publication of the book "Exploratory Data Analysis" (Tukey, 1977). The trend has been facilitated by advances in computer technology which have increased both the power and the accessibility of computers. Biplot techniques include the popular correspondence analysis. The original proponents of correspondence analysis (among them Benzecri) reject probabilistic modelling. At the other extreme, some view graphical display techniques as a mere preliminary to the more traditional statistical approaches. Under the latter view, graphical display techniques are used to suggest models and hypotheses. The emphasis in exploratory data techniques such as graphical displays is on 'getting a feel' for the data rather than on building models and testing hypotheses. These methods do not replace model building and hypothesis testing, but supplement them. The essence of the philosophy is that models are suggested by the data, rather than the frequently followed route of first fitting a model. Some work has gone into developing inferential methods, with hypothesis tests and associated p-values for biplot-type techniques (Lebart et al, 1984, Greenacre, 1984). However, this aspect is not important if the techniques are viewed merely as exploratory. Chapter Two provides the mathematical concepts necessary for understanding biplots. Chapter Three explains exactly what a biplot is, and lays the theoretical framework for the biplot techniques that follow. The goal of this chapter is to provide a framework in which biplot techniques can be classified and described. Correlation biplots are described in Chapter Four. Chapter Five discusses the principal component biplot, and the link between these and principal component analysis is drawn. In Chapter Six, correspondence analysis is presented. In Chapter Seven practical issues such as choice of centre are discussed. Practical examples are presented in Chapter Eight. The aim is that these examples illustrate techniques commonly applicable in practice. Evaluation and choice of biplot is discussed in Chapter Nine.

This thesis deals with controlling a color graphic LED display using an FPGA. The first half of the theoretical part of this paper describes the properties of the used FPGA, the data source and a principle of controlling an RGB LED display. The second half describes an implementation of pulse width modulation and binary code modulation which enables the control of brightness of the display and of color depth of every sub-pixel. The practical part on the other hand describes the designing and the implementation of this module in the VHDL language. Then it explains the transfer of image data from Blackfin processor to the memory via PPI interface, the subsequent process of reading data from the memory, conversion of the data to a serial format and finally it describes the process of sending the data to the LED controller. The module was realized on the Digilent Atlys development board equipped with the Spartan-6 FPGA and was tested on a 32x20 light panel for the firm Ing. Ivo Herman, CSc.

Full textAbstract:
Large Display Arrays (LDAs) use Light Emitting Diodes (LEDs) in order to inform a viewing audience. A matrix of individually driven LEDs allows the area represented to display text, images and video. LDAs have undergone rapid development over the past 10 years in both the modular and semi-flexible formats.
This thesis critically analyses the communication architecture and processor functionality of current LDAs and presents an alternative method, that is, Scalable Flexible Large Display Arrays (SFLDAs).
SFLDAs are more adaptable to a variety of applications because of enhancements in scalability and flexibility. Scalability is the ability to configure SFLDAs from 0.8m2 to 200m2. Flexibility is increased functionality within the processors to handle changes in configuration and the use of a communication architecture that standardises two-way communication throughout the SFLDA.
While common video platforms such as Digital Video Interface (DVI), Serial Digital Interface (SDI), and High Definition Multimedia Interface (HDMI) are considered as solutions for the communication architecture of SFLDAs, so too is modulation, fibre optic, capacitive coupling and Ethernet. From an analysis of these architectures, Ethernet was identified as the best solution.
The use of Ethernet as the communication architecture in SFLDAs means that both hardware and software modules are capable of interfacing to the SFLDAs. The Video to Ethernet Processor Unit (VEPU), Scoreboard, Image and Control Software (SICS) and Ethernet to LED Processor Unit (ELPU) have been developed to form the key components in designing and implementing the first SFLDA.
Data throughput rate and spectrophotometer tests were used to measure the effectiveness of Ethernet within the SFLDA constructs. The result of testing and analysis of these architectures showed that Ethernet satisfactorily met the requirements of SFLDAs.

Full textAbstract:
Display/control gain is the amount of movement that occurs on a display in response to a unit amount of movement on the control. Two studies were conducted to determine the adequacy of identifying the optimum gain for an interface as a method of control-display interface optimization.
The first study examined the effects of changes in both the maximum control input and the display width on target acquisition performance with a touch tablet and a trackball. The hypothesis that an interaction between the control input and the display output would determine performance was not supported for either device. There was a main effect of the control input for the touch tablet, and significant effects of the control input and the display width for the trackball. The results also indicate that, at least for the touch tablet, gain is not a sufficient specification for performance.
The second study evaluated the effects of changes in the display amplitude, the display target width, and the control amplitude. There were significant interactions among these three factors for both touch tablet and trackball target acquisition performance. These results extend the findings of the first study with respect to the inability of gain to predict performance. In addition, the inadequacy of Fitts' Law as it applies to the given interfaces is discussed.<br>Ph. D.<br>incomplete_metadata

Full textAbstract:
Radiologists' workload has been steadily increasing for decades. As digital technology matures it improves the workflow for radiology departments and decreases the time necessary to examine patients. Computer systems are widely used in health care and are for example used to view radiology images. To simplify this, display protocols based on examination data are used to automatically create a layout and hang images for the user. To cover a wide variety of examinations hundreds of protocols must be created, which is a time-consuming task and the system can still fail to hang series if strict requirements on the protocols are not met. To remove the need for this manual step we propose to use machine learning based on past manually corrected presentations. The classifiers are trained on the metadata in the examination and how the radiologist preferred to hang the series. The chosen approach was to create classifiers for different layout rules and then use these predictions in an algorithm for assigning series types to individual image slots according to categories based on metadata, similar to how display protocol works. The resulting presentations shows that the system is able to learn, but must increase its prediction accuracy if it is to be used commercially. Analyses of the different parts show that increased accuracy in early steps should improve overall success.<br>Röntgenläkares arbetsbörda har under flera årtionden ökat. Den digitala sjukvårdsteknologin utvecklas ständigt vilket bidrar till ett förbättrat arbetsflöde och kortare undersökningstider i radiologiavdelningar. Datorsystem används idag överallt inom sjukvården och används bland annat för att visa bilder åt röntgenläkare. För att underlätta visningen används display protocol som automatiskt skapar layouts och hänger bilder åt användaren. För att täcka ett stort antal olika undersökningstyper krävs att användaren skapar hundratals protokoll vilket är en tidskrävande uppgift, och systemet kan ändå misslyckas med att hänga upp bilder om de strikta kraven protokollen ställer inte uppfylls. För att ta bort detta manuella steg föreslår vi att man använder maskininlärning baserat på tidigare sparade presentationer. Klassificerarna tränas på undersökningens metadata och radiologens preferenser på hängning av serier. Den valda metoden går ut på att skapa klassificerare för olika layout-regler och att sedan använda deras output i en algoritm som placerar ut series-typer till individuella bildplatser enligt kategorier baserade på metadata. Denna metod liknar den process de nuvarande display protokollen utför. De presentationer som skapats visar att systemet kan läras upp, men kräver högre precision om det ska användas kommersiellt. Analys av de olika delarna tyder på att ökad precision tidigt i systemet skulle öka den totala precision.

Full textAbstract:
Interaction with mobile devices suffers from a number of shortcomings, most of which are linked to the small size of screens. Artificial tactile feedback promises to be particularly well suited to the mobile interaction context. To be practical, tactile transducers for mobile devices must be small and light, and yet be capable of displaying a rich set of expressive stimuli. This thesis introduces a tactile transducer for mobile interaction that is capable of distributed skin stimulation on the fingertip. The transducer works on a principle that was first investigated because of its potential application to the display of Braille. A preliminary study was conducted on an earlier version of the transducer. It concluded that subjects were able to identify simple Braille characters with a high rate of success. Then, a complete re-design of the transducer addressed the goal of integration in a handheld prototype for mobile interaction. The resulting device comprises a liquid crystal graphic display co-located with the miniature, low-power, distributed tactile transducer. Next, it was needed to measure the perceptual differences between the stimuli that the device could display. Our experiences with one evaluation approach raised questions relating to the methodology for data collection. Therefore, an analysis of the process was carried out using a stimulus set obtained with the device. By means of multidimensional scaling analysis, both the perceptual parameters forming the stimuli space and the evaluation technique were validated. Finally, two experiments were carried out with the objective to develop new mobile interactions paradigms that combined visual and tactile feedback. Both experiments modeled a list scrolling task on the device. The first experiment found a marginal improvement in performance when tactile feedback was employed. It also came at a higher attentional cost dedicated to operating the device. For the second experiment, the scrolling paradigm and the tactile feedback were improved. This lead to a decrease in the reliance on vision when tactile feedback was enabled. Results showed a 28% decrease in the number of key presses that controlled the visibility state of the scroll list.

Full textAbstract:
In any situation where private, proprietary or highly confidential material is being dealt with, the need to consider aspects of data security has grown ever more important. It is usual to secure such data from its source, over networks and on to the intended recipient. However, data security considerations typically stop at the recipient's processor, leaving connections to a display transmitting raw data which is increasingly in a digital format and of value to an adversary. With a progression to wireless display technologies the prominence of this vulnerability is set to rise, making the implementation of 'secure display' increasingly desirable. Secure display takes aspects of data security right to the display panel itself, potentially minimising the cost, component count and thickness of the final product. Recent developments in display technologies should help make this integration possible. However, the processing of large quantities of time-sensitive data presents a significant challenge in such resource constrained environments. Efficient high- throughput decryption is a crucial aspect of the implementation of secure display and one for which the widely used and well understood block cipher may not be best suited. Stream ciphers present a promising alternative and a number of strong candidate algorithms potentially offer the hardware speed and efficiency required. In the past, similar stream ciphers have suffered from algorithmic vulnerabilities. Although these new-generation designs have done much to respond to this concern, the relatively short 80-bit key lengths of some proposed hardware candidates, when combined with ever-advancing computational power, leads to the thesis identifying exhaustive search of key space as a potential attack vector. To determine the value of protection afforded by such short key lengths a unique hardware key search engine for stream ciphers is developed that makes use of an appropriate data element to improve search efficiency. The simulations from this system indicate that the proposed key lengths may be insufficient for applications where data is of long-term or high value. It is suggested that for the concept of secure display to be accepted, a longer key length should be used.
