Accessibility of Voice User Interfaces and Indoor Navigation for Blind Users


Voice-activated personal assistants (VAPAs) offer considerable promise for individuals with disabilities in both home environments (e.g., Google Home, Amazon Echo), and for use while on-the-go (e.g., Apple Siri, Microsoft Cortana, in-car assistants). Our research has examined ways these technologies are used on a daily basis, and the challenges that may be faced when attempt to make interactions. The aim is to identify ways to better support users in scenarios where voice represents either the user's preferred medium or is the sole medium available for purposes of interaction.


More recent work is focusing on (i) analyzing the ways in which guidelines have been designed to support interface designers, (ii) examining ways in which "power users" can better influence design, and (iii) using voice for supporting indoor navigation for individuals with and without disabilities.


The work, most recently funded by Toyota, is conducted in conjunction with Dr. Stacy Branham (UCI) and her team of researchers.
