RealityAlert

Abstract

RealityAlert is a hardware device that we designed to alert immersive virtual environment (IVE) users for potential collisions with real-world (RW) objects. It uses distance sensors mounted on a head-mounted display (HMD) and vibro-tactile actuators inserted into the HMD's face cushion. We define a sensor-actuator mapping, which is minimally obtrusive in normal use, but efficiently alerting in risk situations.
