I specialize in designing intelligent interactive systems that leverage uncertain input technologies. A particular focus of my research is on systems that enhance the capabilities of users with permanent or situationally-induced disabilities. My broader interests include human-computer interaction (HCI), speech and language processing, mobile interfaces, and crowdsourcing.
What's new:
August 2025 – PhD student Blade Frisch's scoping review about designing augmentative and alternative communication (AAC) for use in social and community contexts will appear in the journal Augmentative and Alternative Communication. Congrats to Blade on his first journal article!
August 2025 – PhD student Blade Frisch's paper describing the design workshops he is conducting with autistic adults will appear at ASSETS 2025. Congrats to Blade on his first conference paper!
July 2025 – Steven Ding successfully defended his PhD, Sensing Tap Location Using an Array of Acoustic Sensors. Congrats to the new Dr. Ding!
June 2025 – At the 11th International BCI Meeting, we presented our simulation study comparing the use of an n-gram and a large language model (LLM) in a brain-computer interface (BCI) spelling interface.
April 2025 – PhD student Blade Frisch presented his work on conducting participatory design with people who use augmentative and alternative communication (AAC) at a CHI 2025 workshop. Congrats to Blade on his first workshop paper!
February 2025 – We will present three papers at PETRA 2025 related to improving text input for users who are blind or low vision. The first paper explores using speech recognition confidence scores to highlight likely recognition errors. The second paper tests presenting multiple word predictions at the same time using spatial audio. The third paper reports on interviews we conducted with 12 blind adults about their mobile text input experience.
January 2025 – As part of the CAMBI team, we've been working on a system to allow people with severe physical impairments to type via a brain-computer interface (BCI). Our recent study will appear in the Journal of Neural Engineering.
July 2024 – Sadia Nowrin successfully defended her PhD, Programming by Voice. Congrats to the new Dr. Nowrin!
June 2024 – I've been helping Meta for the last few years on research related to typing in augmented reality (AR). A paper about the system and its evaluation has been accepted for presentation at UIST 2024. Check out the video!
March 2024 – Our evaluation of the eyes-free text input method FlexType with users with visual impairments was accepted at PETRA 2024.
