PhysVib: Physically plausible vibrotactile feedback library to collisions on a mobile device

Abstract

This demo presents a mobile application using PhysVib: a software solution on the mobile platform extending an open-source physics engine for automatic vibrotactile feedback upon collision events in a multi-rate rendering architecture. PhysVib runs concurrently with a physics engine at a low update rate and generates vibrotactile feedback commands at a high update rate based on the simulation results of the physics engine using an exponentially-decaying sinusoidal model. We demonstrate an application showing three wall-object pairs with different material properties, and a user interacts with internal objects to feel vibrotactile feedback from collision events.
