In this paper, we propose Virtual Whiskers, a spatial directional guidance technique by stimulating a cheek using tiny robot arms attached to a Head-Mounted Display (HMD). We performed a directional guidance experiment to evaluate how accurately our method provide the target direction. The result shows our method achieves the average absolute directional error of 2.76 degrees in the azimuthal plane and 7.32 degrees in the elevation plane. We also investigated how effective the cheek stimulation is in a target search task. The average of task completion time in visual condition was M=12.45s, and visual+haptic condition resulted in M=6.91s. Statistical test revealed a significant difference between visual condition and visual+haptic condition.
