Abstract

In spatial navigation, adding haptic cues to visual information lets users understand the spatial information better. Most haptic devices stimulate various body parts, while few devices target our heads that are sensitive to mechanical stimuli. This paper presents Virtual Whiskers, a spatial directional guidance technique using cheek haptics in a virtual space. We created a cheek haptic stimulation device by attaching two tiny robot arms to a Head-Mounted Display. The robot arms trace the cheek with proximity sensors to estimate the cheek surface. Target azimuthal and elevational directions are translated into a point on the cheek surface. The robot arms touch the point to present target directional cues. We demonstrate our technique in two applications.
