Surround haptics

Abstract

In this paper we propose an architecture for rendering rich and high-resolution haptic feedback on the user's body while playing interactive games. The haptic architecture consists of three main elements, namely, haptic engine, haptic API/codec, and haptic display. The haptic engine extracts events from the game, assigns haptic feedback to these events, and sends coded packets to haptic API/codec. The haptic API/codec translates the coded packets and computes driving signals based on carefully evaluated algorithms derived from psychophysical modeling of tactile perception. The driving signals are then routed to the haptic display embedded with an array of vibratory transducers. A user feels high resolution and refined tactile sensations on the body through the display. We have integrated the Surround Haptics system with a driving simulation game to provide an enjoyable gaming experience.
