Haptic Interfaces: Virtual Coupling and Proxy Concept

This lecture covers the definition, scope, and history of haptic interfaces, haptic display characteristics, different types of haptic displays, and design guidelines. It delves into haptic interaction through virtual coupling, transitioning to pseudo-haptic feedback. The concept of a proxy is introduced to prevent discontinuities in collision response, with a focus on improving avatar realism and coherence. The lecture also discusses the implementation of the avatar-proxy concept in haptic workstations, emphasizing visual realism and efficient force feedback. Ongoing research areas include interaction with deformable tissues and software development kits for haptic applications.
