Abstract

A method creates haptic stimulations on a user of an artificial reality system. The system includes a head-mounted display (HMD) and a wearable device. The HMD includes a display and speakers. The wearable device includes a plurality of transducers that can each generate waves to provide haptic feedback to a user. The system displays media content on the display and, in accordance with the displayed media content, determines a virtual object location in the displayed media content corresponding to a physical object location. The system provides, to the user, audio directed to the virtual object location. The system activates one or more transducers to provide haptic feedback at a target location on the user, distinct from the physical object location, to produce haptic feedback whose perceptual interpretation is at the physical object location based on a combination of the displayed media, the provided audio, and the haptic feedback.
