Embodied Digital Therapists with LLM Personalization for Aphasia Rehabilitation: Characterizing Human-AI Collaboration Boundaries

Aphasia following stroke affects millions globally, yet rehabilitation remains severely limited by speech therapist shortages. Existing digital systems rely on static video demonstrations, single-modality assessment, and rule-based feedback, failing to address authentic clinical needs. Through formative investigation…

iGripper: A Semi-Active Handheld Haptic VR Controller Based on Variable Stiffness Mechanism

We introduce iGripper, a handheld haptic controller designed to render stiffness feedback for gripping and clamping both rigid and elastic objects in virtual reality. iGripper directly adjusts physical stiffness by using a small linear actuator to modify the spring’s position along a lever arm, with feedback force gen…

Haptic Rendering of Neural Radiance Fields

The neural radiance field (NeRF) is attracting increasing attentions from researchers in various fields. While NeRF has produced visu- ally plausible results and found its potential applications in virtual reality, users are only allowed to rotate the camera to observe the scene represented as NeRF. We study the hapti…
