Virtual Reality Accessibility With Predictive Trails, Dani Paul Hove

Honors Projects

Comfortable locomotion in VR is an evolving problem. Given the high probability of vestibular-visual disconnect, and subsequent simulator sickness, new users face an uphill battle in adjusting to the technology. While natural locomotion offers the least chance of simulator sickness, the space, economic and accessibility barriers to it limit its effectiveness for a wider audience. Software-enabled locomotion circumvents much of these barriers, but has the greatest need for simulator sickness mitigation. This is especially true for standing VR experiences, where sex-biased differences in mitigation effectiveness are amplified (postural instability due to vection disproportionately affects women).

Predictive trails were developed as …

Voice Controlled Accessibility And Testing Tool (Vcat), Nagendra Prasad Kasaghatta Ramachandra

Computer Science and Engineering Theses

Most current browser-based web applications and software engineering tools, such as test generators and management tools, are not accessible to users who cannot use a traditional input device, such as a mouse and/or a keyboard. To address this shortcoming, this research leverages recent speech-recognition advances to create a chrome browser extension that interprets voice inputs as web browser commands and executes those commands within the browser. As a result, the Voice Controlled Accessibility and Testing tool (VCAT) leverages the Chrome browser to achieve higher accessibility, with the capability to perform webpage navigation using voice commands. The tool is also capable …
