Perceptions and New Wave of
Voice Assistants

Personified voice assistants, such as Alexa and Siri, cultivate interesting power (im)balances between themselves and people with disabilities. To some, these agents may contribute to confidence and self-efficacy, while to others, it may be disheartening to rely on a black-box system. I study the perceptions around voice assistants, and bridge these mental models to newer designs of voice assistants that "empower" users with disabilities.

Microgressive Experiences of People with Disabilities

Social media is a place where marginalized communities are susceptible to subtle forms of discrimination and harm; perpetuating experiences of feeling unwelcomed. Through this study, we aim to understand how people with disabilities experience microaggressions (e.g., ableism, patronization) on social media platforms, and how their social media experience is shaped through such disability-specific microaggressions.

User Experience of Voice Interactions

The "look and feel" of a website often stems from its visual aesthetic, which are inaccessible to people with vision impairments. I'm investigating how voice agents (sreenreaders, voice assistants) can recover this visual and ambient information. Specifically, how can we creatively design voice interactions to deliver the ambience, trust, and emotional responses that are often generated through visual design?

Self-Presentation in Social
Virtual Reality

Accessible Mid-Air Haptics Design

Mid-air haptic interfaces enable rich 3D interactions but are inherantly inaccessible to various users with disabilities. We designed an interactive simulation of a contactless elevator control panel with mid-air touch feedback and accessibility considerations. Despite being fully contactless, the controls are tactile and closely resemble the mental model of ordinary elevator buttons. Published at CHI Interactivity '21'.

Hands-Free Virtual Reality

People with neuromotor impairments have difficulty operating virtual reality controllers, especially if they operate a wheelchair, have lower fine motor ability, or have spasticity in their muscles. To this end, we explored the use of head orientation to onboard the Oculus and navigate menus in virtual reality.
