Abstract:
A multi-orientation fingertip planar tactile feedback device includes a planar tactile feedback actuator. The planar tactile feedback actuator includes a holder and a feedback mechanism, a holding hole and an accommodating cavity are provided in the holder, one end of the holding hole penetrates through the holder, the other end is communicated with the accommodating cavity, the feedback mechanism includes a plurality of feedback parts that are arranged on cavity walls of the accommodating cavity respectively, and each feedback part includes a base, an air bag block and a baffle which are sequentially connected. A structure is simple; a finger touch force can be adjusted; five pairs of electrified coils are arranged, and force feedback vector synthesis can be performed therebetween; a direction of the force feedback generated by the electrified coil can be consistent with a direction of tactile feedback of the distal finger segment by the baffle.
