Abstract:

People have affective reactions towards tasks, artifacts and interfaces. Theses reactions are caused by design features, which operate either through their perceptual attributes or from a sense of control in handling or from past experience. A systematic framework is proposed to conceptualize Affective Human Factors Design or as we call it - Hedonomics. The word Hedonomics is derived from the Greek “hedone” (pleasure – akin to sweet) and “nomos” (laws, principles). The focus is on pleasurable design of artifacts and tasks. Several existing theories may combine to support this framework, including: Human Information Processing, Activity Theory, and Theory of Flow. There are also analogies with past theories – in human need structure, motivation, job satisfaction, and stress research. The problem is now to conceptualize Hedonomics, to propose theories that can be used for design, and appropriate measurement tools. It is particularly important to develop tools to measure and predict affective design – and on an individual level predict user and customer needs for affect.

Abstract:

Objective: To present a structured, narrative review highlighting research into human perceptual-motor coordination that can be applied to automated vehicle (AV)–human transitions. Background: Manual control of vehicles is made possible by the coordination of perceptual-motor behaviors (gaze and steering actions), where active feedback loops enable drivers to respond rapidly to ever-changing environments. AVs will change the nature of driving to periods of monitoring followed by the human driver taking over manual control. The impact of this change is currently poorly understood. Method: We outline an explanatory framework for understanding control transitions based on models of human steering control. This framework can be summarized as a perceptual-motor loop that requires (a) calibration and (b) gaze and steering coordination. A review of the current experimental literature on transitions is presented in the light of this framework. Results: The success of transitions are often measured using reaction times, however, the perceptual-motor mechanisms underpinning steering quality remain relatively unexplored. Conclusion: Modeling the coordination of gaze and steering and the calibration of perceptual-motor control will be crucial to ensure safe and successful transitions out of automated driving. Application: This conclusion poses a challenge for future research on AV-human transitions. Future studies need to provide an understanding of human behavior that will be sufficient to capture the essential characteristics of drivers reengaging control of their vehicle. The proposed framework can provide a guide for investigating specific components of human control of steering and potential routes to improving manual control recovery.

Abstract:

This paper reviews much of the basic literature on stereopsis for the purpose of providing information about the ability of humans to utilize stereoscopic information under operational conditions. This review is organized around five functional topics that may be important for the design of many stereoscopic display systems: geometry of stereoscopic depth perception, visual persistence, perceptual interaction among stereoscopic stimuli, neurophysiology of stereopsis, and theoretical considerations. The paper concludes with the presentation of several basic ideas related to the design of stereoscopic displays.

Abstract:

The tradition in sensory and perceptual psychology is not to pay much attention to individual differences but to focus almost exclusively on normative or generic processes. Nevertheless, consistent individual differences may exist in sensory and perceptual processes, just as they do in all other areas of human behavior where their existence has been investigated. A preliminary study was made of flicker fusion frequency, apparent movement, and three other perceptual tasks as differential measures. With one exception, Letter Search, all of the tests were psychophysical rather than cognitive. All had to do with time; that is, perceptual speed mattered in all of them. The analysis focused on reliability, in the sense of consistency from trial to trial. Four of the five tests showed good reliabilities in this sense, while the fifth was borderline. In one test, Bistable Stroboscopic Motion, the dependent measure, interstimulus interval, showed a consistent though shallow tendency to lengthen with practice. In the remaining four tests practice effects were largely confined to the first two administrations.

Abstract:

Per lungo tempo le scienze informatiche e psicologiche sono state considerate discipline scientifiche completamente differenti. La storia ha però dimostrato che solo l’unione e intersezione tra queste due discipline ha reso possibile il raggiungimento di importanti e rilevanti risultati in aree di ricerca interdisciplinari per natura, come l’area di studio dell’interazione uomo macchina, le interfacce neurali, la sicurezza informatica ed in particolar la visione artificiale, dove teorie e indagine nate dallo studio della percezione visiva sono state la principale fonte di ispirazione per i risultati ottenuti. Molti esempi, alcuni dei quali riportati in questa tesi, dimostrano l’esigenza e il dovere di eseguire studi all’intersezione tra le scienze informatiche e psicologiche. In questa tesi, ci poniamo il talvolta ambizioso obiettivo di costruire un “solido ponte” tra queste due scienze, tramite l’unione e intersezione di conoscenze e metodologie originarie di entrambi i settori di ricerca. Per dimostrare il raggiungimento di tale obiettivo sono stati studiati e analizzati tre differenti casi di studio: il color naming, lo studio dell’attività cerebrale umana durante la simulazioni di compiti chirurgici e il social signal processing. Anche se questa dissertazione si focalizza principalmente sullo studio del color naming nei soggetti italiani, sia tale indagine, sia lo studio dell’attività cerebrale durante l’uso di strumenti di robotica chirurgica e l’analisi e processazione di segnali sociali portano la prova chiara della necessità di integrare queste due discipline, quella psicologica e quella informatica. Solo tale integrazione renderà possibile evolvere verso le più moderne applicazioni informatiche.
For a long time computer science and psychology have been investigated as two completely different scientific fields. Nevertheless, the history of the two sciences has proved that only the interplay of the two made it possible to reach the majority of the most relevant findings in fields that are interdisciplinary by nature as human computer interaction, robotic haptics research, computer graphics, brain-computer interfaces, computer security and particularly computer vision where theories and observations of visual perception have been the main source of inspiration. Several examples, some of which are reported in this thesis, proved the mandatory demand of performing studies at the intersection between the computer science and the psychology. In this thesis we have the ambitious purpose to "build" a solid bridge between these two sciences by blending knowledge and methodology coming from both the fields. To prove the achievement of our purpose three specific case studies have been investigated: color naming, human brain mapping during simulated surgical tasks and social signal processing. Color vision and color naming are very important topics in cognitive psychology but it also have relevant importance to develop mathematical models for the Italian language and perception. In 1969 Berlin and Kay suggested the existence of a semantic universal- ism in color vocabular and one of the main problems that they identified in their research was how to define color categories. In this framework, three main questions were investigated: The color categorization, the existence of a twelfth basic color term, and the extraction of a metric for similarity between pairs of color were examined in the Italian language. In surgical robotics, extensive evidence has suggested the advantages of minimally invasive surgery over open surgery, but contradictory results concerning the benefits of 3D displays used during minimally invasive surgery have been reported. Moreover, the parietal cortex is known to be involved during the execution of tasks demanding spatial and attentional processes and, from the surgeons’s perspective, during surgical procedures both such processes are required. Nevertheless, few studies have investigated the role of the parietal cortex on the surgical performance. In order to elucidate this issue two main questions have been investigated: the involvement of the parietal cortex during visual- spatial and visuo-motor surgical tasks and the effect of monoscopic and stereoscopic vision in surgical robotics on the human performance. The automatic recognition of human behaviour for videosurveillance applications is, without doubt, one of the main challenges in the current multimedia framework. Despite that, the importance of the role of the human being for reaching an efficient intelligent monitoring of the human activity has frequently been underestimated. In this framework, the so-called Social Signal Processing aims at developing theories and algorithms codifying how human beings behave while involved in social interactions, putting together perspectives from sociology, psychology and computer science. Starting from this field three objectives were pursued in this thesis: the automatic detection of groups and the identification and inference of social relationships by the use of three different social cues namely gaze, F-formations and proxemics. Even if this dissertation mainly focuses on the investigation of color naming issues, the study of brain mapping in surgical robotics and the investigation of social signal processing issues provide clear evidence of the need for integrating such two disciplines for moving a step forward in modern computer applications.

Full text

Abstract:

abstract: Previous research has shown that perceptual illusions can enhance golf putting performance, and the effect has been explained as being due to enhanced expectancies. The present study was designed to further understand this effect by measuring putting in 3 additional variations to the Ebbinghaus illusion and by measuring putting kinematics. Nineteen ASU students with minimal golf experience putted to the following illusion conditions: a target, a target surrounded by small circles, a target surrounded by large circles, a target surrounded by both large and small circles, no target surrounded by small circles and no target surrounded by large circles. Neither perceived target size nor putting error was significantly affected by the illusion conditions. Time to peak speed was found to be significantly greater for the two conditions with no target, and lowest for the condition with the target by itself. Suggestions for future research include having split groups with and without perceived performance feedback as well as general performance feedback. The size conditions utilized within this study should continue to be explored as more consistent data could be collected within groups.

Full text

Abstract:

In this report, we evaluate the role of visual areas responsive to motion in the human brain in the perception of stimulus speed. We first identified and localized V1, V3A, and V5/MT+ in individual participants on the basis of blood oxygenation level-dependent responses obtained in retinotopic mapping experiments and responses to moving gratings. Repetitive transcranial magnetic stimulation (rTMS) was then used to disrupt the normal functioning of the previously localized visual areas in each participant. During the rTMS application, participants were required to perform delayed discrimination of the speed of drifting or spatial frequency of static gratings. The application of rTMS to areas V5/MT and V3A induced a subjective slowing of visual stimuli and (often) caused increases in speed discrimination thresholds. Deficits in spatial frequency discrimination were not observed for applications of rTMS to V3A or V5/MT+. The induced deficits in speed perception were also specific to the cortical site of TMS delivery. The application of TMS to regions of the cortex adjacent to V5/MT and V3A, as well as to area V1, produced no deficits in speed perception. These results suggest that, in addition to area V5/MT+, V3A plays an important role in a cortical network that underpins the perception of stimulus speed in the human brain.

Abstract:

Familiar versions of empiricism overemphasize and misconstrue the importance of perceptual experience as a source of scientific knowledge. This chapter discusses their main descriptive and normative shortcomings and sketches an alternative framework for thinking about the contributions of human sensory systems and experimental equipment to scientific knowledge. Rather than assuming that all scientific claims are developed, tested, and modified or rejected in the same way, this chapter suggests that philosophers would do better to look case by case at the epistemic pathways that link the credibility of different scientific claims to different epistemically significant factors.

Abstract:

Perception of object shape is typically accurate and robust, even when objects move behind occluding surfaces, thus fragmenting their visible regions across space and over time. However, when an object is seen moving behind an occluding surface with only two misaligned apertures, a striking perceptual illusion occurs. The object appears distorted in the same direction as the offset of the apertures. This “aperture capture illusion” reveals the limits of spatiotemporal object formation and gives clues as to how the human visual system perceives dynamically occluded objects under normal circumstances. These concepts as well as related factors are explored in this chapter.

Abstract:

This chapter proposes a way to understand the social, distributed and ecological underpinnings of improvised musical activity. It argues that significant aspects of collaborative performance may arise from perceptual, cognitive and action-orientated factors, in relation to prior experience and the broader historical and cultural context. The chapter illustrates ways in which each improviser in a collaboration may attune to different aspects of the circumstances, with idiosyncratic perceptions of the available affordances guided by attentional processes, physical aspects of the human body and musical instrument, and associations with prior experience. The experience of each musician in a collaborative improvisation thus both overlaps with and diverges from those of other musicians in the ensemble. These divergences are as important as the common ground, and are thus essential to any plausible and comprehensive account of collaborative improvisation.

Abstract:

Damage to the human inferior parietal lobe produces an attentional disturbance known as contralateral neglect, and neurophysiological studies in monkeys have begun to unravel the cellular basis of this function. Converging evidence suggests that LIP encodes a sparse topographic map of the visual world that highlights attention-worthy objects or locations. LIP cells may facilitate sensory attentional modulations, and ultimately the transient improvement in perceptual thresholds that is the behavioural signature of visual attention. In addition, LIP projects to oculomotor centres where it can prime the production of a rapid eye movement (saccade). Importantly, LIP cells can select visual targets without triggering saccades, showing that they implement an internal (covert) form of selection that can be flexibly linked with action by virtue of additional, independent mechanisms. The target selection response in LIP is modulated by bottom-up factors and by multiple task-related factors. These modulations are likely to arise through learning and may reflect a multitude of computations through which the brain decides when and to what to attend.

Abstract:

What is representation? How do the more primitive aspects of our world come together to generate it? How do different kinds of representation relate to one another? This book identifies the metaphysical foundations for representational facts. The story told is in three parts. The most primitive layer of representation is the ‘aboutness’ of sensation/perception and intention/action, which are the two most basic modes in which an individual and the world interact. It is argued that we can understand how this kind of representation can exist in a fundamentally physical world so long as we have an independent, illuminating grip on functions and causation. The second layer of representation is the ‘aboutness’ of (degrees of) belief and desire, whose representational content goes far beyond the immediate perceptable and manipulable environment. It is argued that the correct belief/desire interpretation of an agent is the one which makes their action-guiding states, given their perceptual evidence, most rational. The final layer of representation is the ‘aboutness’ of words and sentences, human artefacts with representational content. It is argued that one can give an illuminating account of the conditions under which a compositional interpretation of a public language like English is correct by appeal to patterns emerging from the attitudes conventionally expressed by sentences. The three-layer metaphysics of representation resolves long-standing underdetermination puzzles, predicts and explains patterns in the way that concepts denote, and articulates a delicate interactive relationship between the foundations of language and thought.

Abstract:

The paper studies the image recognition in Kansei engineering. Firstly, the development history of Kansei Engineering is reviewed. The early research object of ergonomics is the explicit physiological and psychological reaction generated after the interaction between human and artificial objects. This type of research object is characterized by objectivity, universality, stability and easiness to measure. Kansei Engineering extends the research object of ergonomics to the implicit psychological reaction generated by the interaction between human beings and artificial objects, which is characterized by subjectivity, difference, fuzziness and unpredictability.Secondly,the perceptual image of the product is discussed. Perceptual images in Kansei engineering are human's feelings and psychological expectations for artificial objects, as well as highly condensed and deep emotional activities. Different groups may have different perceptual images in different stages. In the study of perceptual image, it is necessary to clarify the subject and stage of the perceptual image. Thirdly, the method of product perceptual image recognition is studied. Perceptual image recognition can be divided into two stages: experiment and statistical analysis, which involves the acquisition, representation, modeling and mapping of user perceptual image with product modeling elements. Generally, the test method is to collect product sample pictures and product perceptual evaluation words, combine morphological analysis method and semantic difference method to form a questionnaire, and then select subjects for testing. A series of statistical analyses should be carried out on the questionnaire data, including factor analysis, cluster analysis, multidimensional scale analysis, artificial neural network analysis, etc. The aim of statistical analyses is to establish the mapping relationship between perceptual image and form. Finally, it points out the problems existing in perceptual image recognition, including "the purpose and subject of perceptual image recognition","Questions of subject representation". A more comprehensive research perspective and technical means should be established to study the above problems.

Abstract:

To solve the difficulties in obtaining user requirements and establishing objective and effective product modeling constraints in product design , A research model of design method based on user perceptual imagination and product modeling constraints was constructed. Firstly, based on the collection of user information, the KJ method is used to obtain the accurate perceptual cognition of users about the product. To address the problem of strong subjectivity of data acquisition in the process of user imagery cognition research, on the basis of user perceptual cognition, the product perceptual imagery semantics is targeted to obtain user perceptual demand information.Then, the user data and the user perceptions obtained from the interviews are combined, and the user perceptual needs are derived through filtering. Next, the complex constraint theory is used as a guide to summarize the design constraint problem and establish the product modeling constraints. Finally, by integrating product perceptual imagination and morphological constraints, product design positioning is derived. The method model of this study can accurately derive a product design orientation based on user needs and objective constraints of the product, and improve design effectiveness and accuracy.

Abstract:

Human height is usually determined by objective measures. Taking into account that body height can have perceptual dimensions, it seems interesting to investigate this personal attribute by a more subjective approach. However, for this it would be former necessary to establish the capability to discriminate difference between figures depicturing body heights. Thus, the objective of this study was to establish the smallest perceptible difference whilst judging the similarity between different human figures representing body heights. Methods: 140 pairs of human figures were presented to 37 participants. The differences between human figures varied from 0 (equal) to 6 cm proportionally to the real height. Each participant judged whether the figures were similar or different. Results: The percentage of correct answers increased when the difference between figures increased. This percentage was higher than 70% for differences corresponding to 4 cm or higher of the real height for both genders. Conclusion: Relative difference (sensory threshold) of 4 cm was consistently established for visual discrimination of height in pictorial human body. This sensory threshold can be considered when studies on perceptual body height are conducted in the future.

Abstract:

The design and implementation of multi-modal information displays can be affected by individual differences within the target user population. These differences manifest themselves at a number of sensory, perceptual, and cognitive levels. In general, such differences and their ranges are rarely taken into account in system design. Instances of significant differences among “normal” individuals will be considered particularly in the visual, auditory, and tactile sensory modalities. As will be discussed in this review of some of the pertinent literature, there can be substantial variation in sensation, perception, and cognition both within an age group as well as over the age span of the target population. For example, because the ages of military personnel can range over five or six decades, device designers have to account for the fact that levels of sensory sensitivity and acuity deteriorate significantly with age. This paper will survey a number of these individual differences, particularly those that have the potential for complicating the design and general application of informational displays for the military. Subtle variations in individual sensitivity and even perceptual “style” can undermine the “one-size-fits-all” philosophy of display design. These have the potential to affect the utility of the system under battlefield stress conditions.

Abstract:

With the increasing problem of air pollution and the increase of rhinitis patients, nasal cleaning has become a problem, and the home electric nasal washer has a good market prospect as the main device for nasal rinsing. The study applied the methods related to Kansei Engineering to quantify the perceptual vocabulary, including collecting and screening the perceptual element vocabulary, selecting representative product samples, and establishing the perceptual imagery space using the semantic difference scale. Then the data evaluation results were input into the software SPSS for factor analysis and principal component analysis, and the key words of design elements that meet users' needs were determined to be "mild", "safe", "clean " "comfortable", representing the user's perceptual preference for the electric nose washer. Combined with the product samples, we analyzed the correlation between users' perceptual imagery and product elements, summarized the design points, and finally designed the product based on the design points. The study provides a new way of thinking and direction for the design of electric nasal wash for home use that is integrated with the user's affective needs.

Abstract:

In the sports product industry, technical apparel materials can be developed to be perceived warm or cool to the human touch. Those created for warm touch are typically for cold environments - generating warmth for athlete comfort, whereas cool touch materials are developed for hot environments – making the athlete’s skin surface feel cool and fresh. These attributes can be engineered into the face or back side of the material – providing different point-of-purchase and next-to-skin perceptual experiences. The goal of this study was to define warm and cool touch effusivity spectrums that the sports apparel industry can reference when developing new technical materials. The warm and cool touch characteristics of common sports materials were evaluated mechanically with a Modified Transient Plane Source (MTPS) sensor and perceptually with a human subject fingertip test protocol. From the data collected, cool and warm touch effusivity spectrums were determined for face and back material sides. For the face side of the material specimens, subjects’ perception of warmth was at an average effusivity value of 145.9 (+/-23.1), and cool at 182.2 (+/-19.7). For the back side of the specimens, the materials were perceived warm at 138.6 (+/-22.6), and cool at 177.3 (+/-19.3). The results of this study provide sports apparel material developers insight into target effusivity value ranges for athlete warm or cool touch perceptual experiences.
