Vestibular loss, which can manifest as dizziness, imbalance, or spatial disorientation, is widespread and often caused by inner ear hair cell malfunction. To address these problems, we are developing a vestibular implant analogous to cochlear implants for the deaf. This vestibular prosthesis provides pulsatile electrical stimulation to the vestibular nerve. Prosthesis effectiveness is assessed using the vestibulo-ocular reflex (VOR), since the VOR helps stabilize gaze in healthy individuals by evoking eye movements that compensate for head movements. In this thesis, the prosthesis was used to probe the high frequency VOR in squirrel monkeys and guinea pigs. In two studies, modulated stimulation was applied acutely to characterize the VOR between 1.5 and 701 Hz. A third study characterized the VOR response to chronic stimulation with a constant rate of 250 Hz. The VOR has previously been characterized up to 50 Hz in monkeys and 2 Hz in guinea pigs by physically rotating subjects. This range was extended in these studies, by using electrical stimulation from the prosthesis. Eye movement spectral peaks were used to characterize the VOR frequency response. The VOR was measurable up to 267 Hz in squirrel monkeys and 151 Hz in guinea pigs. The magnitude response was similar in both species - it increased gradually with frequency, peaked (at 140 Hz in squirrel monkeys and 50 Hz in guinea pigs), and then rolled off.
(cont.) The high frequency fall-off was consistent with the low-pass nature of the oculomotor plant. The phase responses had a linear lag with frequency, consistent with a fixed 4 ms delay of the VOR three-neuronarc. Since the VOR responds at high frequencies, this raises the question whether the prosthesis causes eye movements at the prosthesis pulse rate, since electrical stimulation elicits neural responses that are phase-locked with the stimulation. Such responses might cause visual blurring for a patient using the device. This thesis shows that such eye movements are measurable, and have substantial velocity magnitude of 8.1 deg/s initially, but within 30 minutes the magnitude reduces by 80% and probably does not yield perceptible visual blurring.

Texto completoA indústria dos vídeo jogos é actualmente uma das mais valiosas e lucrativas do género. Como se espera de qualquer membro activo desta indústria, os produtores de vídeo jogos aspiram a obter uma quota desse mercado e das receitas. Hoje, a exigência relativa ao lançamento de vídeo jogos é tal que, por vezes, uma das etapas cruciais do desenvolvimento do produto é preterida – a avaliação da usabilidade – o que resulta em jogos de menor qualidade. Ainda, os vídeo jogos que são avaliados acabam por o ser à custa de métodos que não são totalmente correctos e que não respeitam à unicidade do media. O presente trabalho surge, portanto, com o objectivo de apresentar uma nova metodologia que vá ao encontro do referido problema. A metodologia proposta é uma parte de um estudo empírico que contou com participantes com distintos níveis de experiencia com vídeo jogos e que fez uso de dois instrumentos: um questionário e em segundo lugar, uma tecnologia que não gera consenso – o eye tracking – um método que mensura os movimentos e as posições do olho. Os dados obtidos através dos questionários bem como os resultados do eye tracking foram analisados e serviram de base para o objectivo maior deste estudo: o desenvolvimento de guidelines (linhas orientadoras) que possam assistir na melhoria da concepção e do desenvolvimento de vídeo jogos. ABSTRACT: The video game industry is presently one of the most valuable and lucrative of its kind. As is expected from any active member in this industry, video game developers aspire to secure a share of that market and income. Currently, the demand to deliver video games is such that at times, one of the most important moments of product development is overlooked – usability evaluation – resulting in less enjoyable or playable video games. Furthermore, those that are evaluated are done so at the cost of methods that are not completely accurate and that do not respect the uniqueness of the media. The present study emerges, therefore, with the objective of presenting a new methodology that can challenge the mentioned predicament. The proposed methodology is one part of an empirical study that counted with participants of various gaming experiences and made use of two instruments: a questionnaire and secondly, a technology many have yet to accept – eye tracking – a method capable of measuring eye movement and eye positions. The acquired data from the questionnaires along with eye tracking results were analyzed and served as the basis for the greater objective of this study: the development of guidelines that can assist in the augmentation of video game development.

Texto completoSaccadic and vestibular-evoked eye movements are similar in that their three-dimensional kinematic properties show eye position-dependence. When the line of sight is directed towards an eccentric target, the eye velocity axis tilts in a manner that depends on the instantaneous position of the eye in the head, with the magnitude of tilt also depending on whether the eye movement is saccadic or vestibular-evoked. The mechanism responsible for producing eye velocity axis tilting phenomena is not well understood. Some authorities have suggested that muscle pulleys in the orbit are critical for implementing eye velocity axis tilting, while others have suggested that the cerebellum plays an important role. In the current study, three-dimensional eye and head rotation data were acquired, using the magnetic search coil technique, to confirm the presence of eye position-dependent eye velocity axis tilting during saccadic eye movements. Both normal humans and humans with cerebellar atrophy were studied. While the humans with cerebellar atrophy were noted to have abnormalities in the two-dimensional metrics and consistency of their saccadic eye movements, the eye position-dependent eye velocity axis tilts were similar to those observed in the normal subjects. A mathematical model of the human saccadic and vestibular systems was utilized to investigate the means by which these eye position-dependent properties may arise for both types of eye movement. The predictions of the saccadic model were compared with the saccadic data obtained in the current study, while the predictions of the vestibular model were compared with vestibular-evoked eye movement data obtained in a previous study. The results from the model simulations suggest that the muscle pulleys are responsible for bringing about eye position-dependent eye velocity axis tilting for both saccadic and vestibular-evoked eye movements, and that these phenomena are not centrally programmed.

Texto completoThe increasing amount of smart devices in our everyday environment has created new problems within human-computer interaction such as how we humans are supposed to interact with these devices efficiently and with ease. So far, context-aware systems could be a possible candidate to solve this problem. If a system automatically could detect people's activities and intentions, it could act accordingly without any explicit input from the user. Eyes have previously shown to be a rich source of information about a person's cognitive state and current activity. Because of this, eyes could be a viable input modality for extracting information from. In this thesis, we examine the possibility of detecting human activity by using a low cost, home-built monocular eye tracker. An experiment was conducted were participants performed everyday activities in a kitchen to collect eye movement data. After conducting the experiment, the data was annotated, preprocessed and classified using multilayer perceptron and random forest classifiers.Even though the data set collected was small, the results showed a recognition rate of between 30-40% depending on the classifier used. This confirms previous work that activity recognition using eye movement data is possible but that achieving high accuracy is challenging.

Texto completoIn addition to microsaccades, the attention allocation during eye fixation and eye pursuit are considered as well. We demonstrate that, during eye fixation, the local image content around the area of a fixation point is a significant factor to influence the fixation duration. However, during pursuit, the pursuit direction, rather than image contents, is important to decide attention allocation. According to these results, a top-down attention model based on types of eye movements is built. Three types of eye movements are considered separately in the model. They are eye fixation, eye pursuit, and saccadic eye movements (including microsaccades). The model is applied to the design of an interactive 2D video game. We demonstrate that the game is successfully designed in different difficulty levels through the analysis of attention allocation by our attention model. Our results imply that the attention modeling can be used to alter the game play so as to provide varying difficulty levels and it is also promising to take advantage of eye tracking data for broader applications, such as for navigation, intelligent map searching, augmented reality, and others.

Texto completoPeople with intellectual disability have historically been excluded from the benefits of psychotherapy, despite the higher incidence of mental illness, in general, and PTSD, in particular, in this population. It had been thought that intellectual disability precluded the cognitive and emotional ability required to participate in therapy. A growing body of literature is reporting successful application of a number of these therapies, established as empirically effective for the general population, with people with intellectual disability. Typically, minor modifications are required. Criticism continues, now based on the problem of using therapies with a population for which they have not been empirically established as effective. The current study contributes to the empirical process of establishing effectiveness of a specific trauma therapy for people with intellectual disability. It applies the EMDR therapy to six participants in a multiple-baseline, ABA, time-series experiment design. EMDR has previously been used with people with intellectual disability, reporting improved symptoms and functioning for the more than 35 cases published. For the current study, the participants were all diagnosed with PTSD and other diagnoses reflecting the emotional distress associated with histories of multi- and poly-traumatization, beginning at an early age. They received weekly assessments on multiple measures: self-report, physiological, observer ratings, and continuous actigraph recordings. Each participated for a minimum of 60 weeks, which included: an A phase, the Baseline; a B phase, the Intervention; and, a second A phase, Maintenance. After a Hiatus of six weeks, participants returned for Follow-up testing. The EMDR therapy was delivered during the Intervention phase, only. All participants lost the diagnosis of PTSD and showed emotional and functional improvement on a number of measures. The self-report measures produced the most descriptive time-series data, providing indication of change in a number of dimensions, visually interpretable from graphs of the data, included in this document. Linear regression analyses support visual analysis. Additional research in using the EMDR therapy with people with intellectual disability is recommended, with the purpose of establishing it as appropriate for use with this population. Limitations of the study are addressed.

In the modern era of convenient transportation and information abundance people can easily get information from the internet and reach any place in mind with transport. However, for the physically-limited community, they can not move at will, but their eyes are able to rotate freely. So the development of a set of eye movement control system makes their daily life easier and more complete. The purpose of this research is to construct a set of "eye movement control system", using EOG method (Electro-OculoGram, EOG) as a way to capture eye movement signals. Eye movement signals are processed and identified by circuit boards, sent to microprocessor to transform into control signals, and finally linked as control signals to the controller, so that the user can execute the action they want by using this system. In this thesis, the tracking of eye movement is used to construct four different commands, and the user can quickly and precisely control switch. The equipment structure used in this system is simple, has small size components, easy to carry, possess good stability and easily controlled by the user.

In the process of reading, the location and duration of eye fixations varied accroding the language properties of the text. Using the eye tracker nowdays, it precisely records the location and fixation duration of eye movements. That gives an opportunity to understand the cognitive operations of reading. Furthermore, the eye movement contingent display technique is capable to change the display with both the speed and precision. It changes the text on the computer screen at specific location and time, according the location where the eyes are fixating. This advanced technique provides the possibility to explore the nature of dynamic processing of reading. Experiment One uses the moving window paradigm to measure the perceptual span of Chinese reading. It showed that the range of perceived characters in reading includes four characters to the right of fixations. Experiment Two also uses the moving window paradigm but the time of showing "window" is varied. It showed that the characters in peripheral were perceived within 90 msec in the beginning of fixations. The time to mask the peripheral text did not affect the fixation duration of display change, but the time of next fixation. Experiment Three uses the boundary paradigm to show the type of character information can be retrieved in peripheral and integrated with the information on the next fixation. It showed the phonological code can be retrieved in peripheral, but the orthographic code is dominated when integrating information across fixations. Experiment Four uses the fast priming paradigm to show the type of information can be retrieved on fixations. It showed the same pattern for both the third and forth experiment. The phonological effect can be obtained under certain circumstances, when the availability or validity of orthographic information is reduced. The dynamic processing of eye movements in reading and a general model for cognitive operation are discussed.
