DUB Seminar will be conducted using Zoom, via an invitation distributed to the DUB mailing list. Participants who are logged into Zoom using a UW account will be directly admitted, and participants who are not logged in to a UW account will be admitted using a Zoom waiting room.
How to leverage AI to enhance and augment users’ interaction with computers is a grand challenge in HCI. Model-based interaction is a principled approach to addressing this challenge. It creates mathematical models to understand, explain, and predict interaction, and uses models to guide the development of input technologies. In this talk, I will introduce our research of using this model-based approach to create AI-powered writing systems that can (1) infer users’ communication intention from noisy input such as eye gaze, voice, and finger touch, (2) adapt to individuals and support text input on invisible and imaginary keyboards, and (3) detect whether older adults develop early signs of Parkinson’s Disease from computer input. The secret ingredient behind these intelligent input systems is probabilistic modeling which can quantify and resolve uncertainty in interaction and integrate multimodal input to infer users’ interaction intention.
