I present research in enhancing exercise and art exploration for people who are blind or low vision.

Abstract: Blind people rely mostly on the auditory feedback of screen readers to consume digital information. Efficiency is a problem especially in situations where relevant information must be recognized among large amounts of irrelevant information. Sighted people use scanning as a strategy to achieve this goal, by glancing at all content expecting to identify information of interest to be subsequently analyzed with further care. In contrast, screen readers rely on a sequential auditory channel that …

Abstract: It is still recognized as a challenge task while blind and visually impaired people travel outdoor independently, even if there are a number of assistive mobility aids available. In addition to building universal facilities in urban and rural environments for them, it is essential to develop novel mobility assistive technologies and systems to satisfy their increasing demands for mobility. To investigate those demands, an international survey with 106 blind and visually impaired people from …

This thesis demonstrates the importance of interactive maps for visually impaired people and their spatial cognition.

We explore individual differences among blind people and assess how they are related with mobile interface demands, both at low (e.g. performing an on-screen gesture) and high level (text-entry) tasks.

This work examines how HCI and CS techniques can impact language development , empathy and the role communication impairment has on linguistic patterns and conversation quality.

This dissertation explores a consumer device-driven approach that is centered on multiple view perspectives (MVP)

We have studied real world pointing use from older adults and individuals with motor impairments and developed novel techniques to analyze their performance.

I have also addressed the shortcomings of existing HCI models and hope to develop a system that will be easier to use than the existing models and support both able-bodied and disabled users.

As a proposed solution to this situation, from the engineering perspective, the methodological support AWA (Accessibility for Web Applications) is presented in this thesis.
