Description
Games have traditionally had a high barrier to entry because they necessitate unique input devices, fast reaction times, high motor skills, and more. There has recently been a push to change the design process of these games to include people with disabilities so they can interact with the medium of games as well. This thesis examines the current guiding principles of accessible design, who they are being developed by, and how they might help guide future accessible design and development. Additionally, it will look at modern games with accessibility features and classify them in terms of the Game Accessibility Guidelines. Then, using an interview with a lead developer at a game studio as aid, there will be an examination into modern game industry practices and what might be holding developers or studios back when it comes to accessible design. Finally, further suggestions for these developers and studios will be made in order to help them and others improve in making their games more accessible to people with disabilities.

Description
Waggle Ballet explores the possibility of increasing access to ballet for blind audience members by using a combination of live music, accessible choreography, a sensory based workshop, and wearable sonification technology. Waggle Ballet is a classical ballet excerpt that addresses the limitations presented by audio descriptions. Where audio descriptions serve to describe exactly what can be seen on stage for audience members with blindness or vision impairments, Waggle Ballet uses other sensory elements to trigger the imagination and create a sound environment that is generated through ballet movements with the help of motion capturing sensors and thematic sound outputs. The piece was performed in front of a live audience of varying sight abilities with the live musical accompaniment of the bass clarinet. A mini workshop was given that incorporated storytelling and touch to help audience members become familiar with the environment created in the piece. With all the elements coming together, Waggle Ballet hopes to evoke a unique experience that draws from the aspects of ballet performance beyond purely visual aesthetics.

Description
This pilot study examined aspects of post-secondary education at Arizona State University (ASU) in relation to how Universal Design for Learning (UDL) aligned strategies are used to support students, especially those who identify as having Attention-Deficit/Hyperactivity Disorder (ADHD). Students with ADHD have different needs from peers without ADHD, particularly in self-regulation and executive function (APA, 2022). UDL strategies are designed to help create educational experiences that are accessible to diverse learners of all backgrounds, and they are implemented through three main principles: multiple means of engagement, expression, and representation (CAST, 2018). UDL guidelines which expand upon the principle of multiple means of engagement were investigated in relation to building a better framework of learning for students with ADHD at a large public university in the Southwestern US. I aimed to better understand (a) student perceptions of ASU faculties' implementation of instructional strategies aligned to UDL’s principle of multiple means of engagement (b) student perception of the benefit of using specific UDL aligned strategies, and (c) the relationship between the engagement UDL strategies used and their perceived benefit to students’ academic success. A survey was used to collect data from a sample within ASU’s population of students. The survey data were analyzed using descriptive statistics as well as an independent samples t-test to compare variables. Findings from this pilot study can greatly benefit the quality of learning that students receive, could have the potential to inform future studies, as well as provide additional data to faculty members about student perception of the use and benefit of instructional strategies aligned to the UDL principle of multiple means of engagement. With the results of the study, educators can better understand student needs and increase student academic benefit within a college environment.

Description
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.

Description
Libraries provide a needed third place for students to engage with their peers and faculty, both academically and socially. Staff behavior, knowledge, and skills in providing an accessible and inclusive environment are key to helping students with disabilities feel that they belong in the libraries. This makes training in disability and accessibility awareness a necessary component of the overall program for the library. This study assessed a locally-developed, online training program for staff of all levels that was intended to improve staff knowledge and skills in disability etiquette, library services and spaces that support people with disabilities, and the policies that govern this work. The program used the four-part Deines-Jones (1999) model for its content and the core principles of andragogy for its instructional design. Assessment focused on changes in beliefs and knowledge using an adapted standardized scale, and evidence for learning from responses to training program questions, focus group discussions, and survey responses. Further development of the training program was informed by the principles of andragogy. Participants in the training program improved their scores in the knowledge domain but had no change in their beliefs domain. Learning was most evident in spaces where it engaged with previous knowledge and supportive customer service approaches. Participants identified and, in several cases, independently pursued new questions that were prompted by the training program. On the whole, participants found the training to be supportive and engaging, with minor changes to structure and focus recommended for the next iteration.

Description
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.

Description
The goal of this study was to gain insights from adults on the autism spectrum regarding their recommendations for improving the accessibility of stores and restaurants. Four adults who indicated that they had a diagnosis of autism spectrum disorder or Asperger’s Syndrome volunteered to participate in a qualitative interview. The questions that participants were asked centered around their experiences in stores and restaurants, current accessibility guidelines, the impact of COVID-19 on their experiences, and their recommendations for increased accessibility. Recommendations fell into two main categories: changes to the environment and accommodations that could be provided. Participants suggested multiple ways to reduce their sensitivities to noise in stores and restaurants like lowering the music, creating a quiet hour, or providing noise cancelling headphones. Further efforts are needed to fully understand the issue of accessibility for autistic individuals.

Description
Although many data visualization diagrams can be made accessible for individuals who are blind or visually impaired, they often do not present the information in a way that intuitively allows readers to easily discern patterns in the data. In particular, accessible node graphs tend to use speech to describe the transitions between nodes. While the speech is easy to understand, readers can be overwhelmed by too much speech and may not be able to discern any structural patterns which occur in the graphs. Considering these limitations, this research seeks to find ways to better present transitions in node graphs.
This study aims to gain knowledge on how sequence patterns in node graphs can be perceived through speech and nonspeech audio. Users listened to short audio clips describing a sequence of transitions occurring in a node graph. User study results were evaluated based on accuracy and user feedback. Five common techniques were identified through the study, and the results will be used to help design a node graph tool to improve accessibility of node graph creation and exploration for individuals that are blind or visually impaired.

Description
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.

Description
The rate of vaccinations has been consistently decreasing in the past years in children of ages 0-18. Multiple factors and barriers contribute to these low rates. This comparative case study investigated the accessibility of information regarding childhood vaccinations to parents in areas with differing poverty levels in the greater Phoenix region, specifically in the West Valley, Downtown Phoenix, and the East Valley. Pediatric clinics, public elementary schools, and public libraries were visited in each area to assess how much information was available where. The analysis produced unexpected results: the West Valley, which had the highest poverty level, contained the most amount of accessible information for parents in many languages, while the East Valley, with a low poverty level, had almost no information accessible to parents of these children. Implications for future research, policy, and practice are discussed. Based on these unexpected results, one recommendation is to develop a pamphlet that could be distributed to these public places to raise awareness of the importance of vaccinations in children to parents.
