Abstract
A method generates synchronized auditory and haptic feedback for artificial-reality environments. The method includes performing a simulation of a user interaction with a virtual object in an artificial-reality environment. The user interaction (i) traverses a surface of the virtual object (e.g., running a finger over a textured surface), and (ii) includes a set of contact events (e.g., a sparse set of events). The method also includes estimating a trajectory of the user interaction with the virtual object based on the set of contact events. The method also includes determining a surface profile associated with the surface of the virtual object, generating an excitation force profile according to (i) the estimated trajectory and (ii) the surface profile, and rendering, based on the excitation force profile, audio and synchronized haptic feedback for the user interaction.
