We present ForceSight, a non-contact force sensing approach using laser speckle imaging. Our key observation is that object surfaces deform in the presence of force. This deformation, though very minute, manifests as observable and discernible laser speckle shifts, which we leverage to sense the applied force. To investigate the feasibility of our approach, we conducted studies on a wide variety of materials. We also demonstrated the applicability with several example applications.

A new interaction technique that lets users' hands become virtual objects by imitating the objects themselves. For example, a thumbs-up hand pose is used to mimic a joystick. We created a wide array of interaction designs around this idea to demonstrate its applicability in object retrieval and interactive control tasks. Collectively, we call these interaction designs Hand Interfaces.

AURITUS is an extendable and open-source optimization toolkit designed to enhance and replicate earable applications. AURITUS handles data collection, pre-processing, and labeling tasks using graphical tools and provides a hardware-in-the-loop (HIL) optimizer and TinyML interface to develop lightweight and real-time machine-learning models for activity detection and filters for head-pose tracking.

Human attention is a scarce resource in modern computing. Quick Question explores use of reinforcement learning (RL) to schedule microtasks while minimizing user annoyance and compare its performance with supervised learning. We model the problem as a Markov decision process and use Advantage Actor Critic algorithm to identify interruptible moments.
