This paper presents the design and evaluation of a haptic interface for augmenting human-human interpersonal interactions by delivering facial expressions of an interaction partner to an individual who is blind using a visual-to-tactile mapping of facial action units and emotions. Pancake shaftless vibration motors are mounted on the back of a chair to provide vibrotactile stimulation in the context of a dyadic (one-on-one) interaction across a table. This work explores the design of spatiotemporal vibration patterns that can be used to convey the basic building blocks of facial movements according to the Facial Action Unit Coding System. A behavioral study was conducted to explore the factors that influence the naturalness of conveying affect using vibrotactile cues.

Studies have previously found a significant relationship between student writing center usage and demographic factors including gender, GPA, and English-language proficiency (Salem, 2015). Additional research has been conducted on writing center outcomes and student conceptions and misconceptions of writing centers as academic resources. However, previous scholarship has attested to the need for continuous research into writing center usage patterns and the factors that affect them. This will allow centers to make the necessary changes and improvements to become more accessible and inclusive for the benefit of all students. The present research contributes to the ongoing discussion about why students choose to use or not use the writing center and how their identities and pre-existing ideas about the center inform this decision. Further, it addresses research gaps by surveying students in an honors college setting at a large public university and considering new decision-making factors such as race, mental health, and social stigma. By comparing students demographics and impressions of the Barrett Writing Center (BWC) on the ASU campus, the study draws conclusions about the significant gap between positive perception and usage, the influence of social anxiety and stigma amongst honors students, the successes and failures of tutoring for second language English speakers, and the benefit derived by students who attend multiple writing center sessions. Suggestions to improve the BWC and guide future research are offered based on these observations and significant trends in the data.

Over the past decade, advancements in neural networks have been instrumental in achieving remarkable breakthroughs in the field of computer vision. One of the applications is in creating assistive technology to improve the lives of visually impaired people by making the world around them more accessible. A lot of research in convolutional neural networks has led to human-level performance in different vision tasks including image classification, object detection, instance segmentation, semantic segmentation, panoptic segmentation and scene text recognition. All the before mentioned tasks, individually or in combination, have been used to create assistive technologies to improve accessibility for the blind.

This dissertation outlines various applications to improve accessibility and independence for visually impaired people during shopping by helping them identify products in retail stores. The dissertation includes the following contributions; (i) A dataset containing images of breakfast-cereal products and a classifier using a deep neural (ResNet) network; (ii) A dataset for training a text detection and scene-text recognition model; (iii) A model for text detection and scene-text recognition to identify product images using a user-controlled camera; (iv) A dataset of twenty thousand products with product information and related images that can be used to train and test a system designed to identify products.

Individuals with voice disorders experience challenges communicating daily. These challenges lead to a significant decrease in the quality of life for individuals with dysphonia.

Individuals with voice disorders experience challenges communicating daily. These challenges lead to a significant decrease in the quality of life for individuals with dysphonia. While voice amplification systems are often employed as a voice-assistive technology, individuals with voice disorders generally still experience difficulties being understood while using voice amplification systems. With the goal of developing systems that help improve the quality of life of individuals with dysphonia, this work outlines the landscape of voice-assistive technology, the inaccessibility of state-of-the-art voice-based technology and the need for the development of intelligibility improving voice-assistive technologies designed both with and for individuals with voice disorders. With the rise of voice-based technologies in society, in order for everyone to participate in the use of voice-based technologies individuals with voice disorders must be included in both the data that is used to train these systems and the design process. An important and necessary step towards the development of better voice assistive technology as well as more inclusive voice-based systems is the creation of a large, publicly available dataset of dysphonic speech. To this end, a web-based platform to crowdsource voice disorder speech was developed to create such a dataset. This dataset will be released so that it is freely and publicly available to stimulate research in the field of voice-assistive technologies. Future work includes building a robust intelligibility estimation model, as well as employing that model to measure, and therefore enhance, the intelligibility of a given utterance. The hope is that this model will lead to the development of voice-assistive technology using state-of-the-art machine learning models to help individuals with voice disorders be better understood.

Improving Physical Accessibility at Arizona State University: A Student Perspective

In an analysis of federal ADA law, we find that the ADA—the law that protects disabled people from exclusion in public spaces—has a fundamental inefficiency: the only way to fix accessibility issues under the ADA is to file a civil or Department of Justice (DOJ) lawsuit. This challenge leads to the perpetuation of inaccessibility and accessibility problems in public settings. To examine this issue on the Arizona State University Tempe (ASU Tempe) campus, I walked through 55 ASU Tempe classroom and research buildings and compiled a list of each accessibility problem present; I created digital floor plans detailing the location of each accessibility concern; and I worked with ASU professionals—such as Arizona State’s Coordinator of Accessibility (ADA) Compliance and professional staff at the Disability Resource Center—to remedy these accessibility issues. Through my research, I identified two areas of improvement regarding accessibility at ASU Tempe: the need for a streamlined tracking and fixing process of accessibility problems on-campus; and the need for an easy-to-access online form where students can report accessibility issues on-campus. I also discovered that despite the problems that need to be addressed, ASU’s professionals are committed to accessibility compliance compared to other institutions. However, despite the commitment from ASU professionals, as well as the ASU charter stating that “[ASU] is ...measured not by whom it excludes, but by whom it includes and how they succeed,” expansion of accessibility for students with physical disabilities on the ASU Tempe campus remains a needed area of change. This will ultimately promote equal educational opportunity for all students, regardless of ability. Furthermore, accessibility involves a continual process of assessment and improvement in spite of budgetary limitations and widespread disability stigmatization.

Libraries have historical and contemporary importance as public spaces that serve a purpose beyond storing books. In our thesis project, we wanted to ensure that the ASU Library was fulfilling this role for our student community. Based on a survey of 136 members of the Arizona State University community regarding accessibility of the Libraries, the results found that the ASU Library system could benefit from more accessible and digital content and programming. In response to our findings, we created a digital book display which highlighted resources about critical disability studies, the importance of community spaces and libraries in particular, as well as information about universal design. This book display serves as an example of what the future of book displays could be and how to create inclusive spaces in the university Library system.

Transportation around campus on time is crucial for in-person college students looking to succeed in their studies. Unfortunately, inequities have arisen between the ability of able-bodied students to get to and from class and permanently or temporarily disabled students looking to do the same. ASU’s solution to this problem, the Disability Access and Resource Transportation (DART) service, does not adequately address the needs of its targeted customers properly. Unfortunately, student surveys and anecdotal evidence from students’ lived experiences have demonstrated that DART often leaves students waiting for more than half an hour for a ride, causes students to miss class, and is altogether unreliable in today’s age where punctuality is key to success. Our goal in our thesis project was to create an equal on-campus transportation playing field for students with and without mobility issues so that a students’ ability to get around campus would never serve as a hindrance to his/her ability to, at a minimum, earn a degree; ideally empowering all students to thrive regardless of their personal circumstances.
