Investigation of On-Skin Electromagnetic Actuator for Signaling Direction via Tactile Cues.

This work contributes an investigation of on-skin electromagnetic actuator for indicating directions through tactile cues. In the study (N = 16), the actuator was tested on three locations on participants' arms. We compared the perception accuracy on these locations and draw the conclusion that the participants could identify the stimulus clearly with the actuator begin placed on the underside of the wrist best. Taken together, our result demonstrates that our work would be used as an additional stimulus combined with other haptic interaction to deliver rich information to the users in potential.
