Shear tactile display system for communicating direction and other tactile cues

摘要

A tactile display comprises a contact pad, operable to engage a target area of a user's skin. A restraining system is operable to restrain a portion of the user's skin distal from the target area of the skin. An actuation system is operably coupled to one of: i) the contact pad and the ii) restraining system. The actuation system is capable of moving the contact pad and the restraining system relative to one another to create a shear force across the target area of the user's skin to thereby provide tactile information to the user.

1. A tactile display, comprising:
a restraining system including: i) a base component having a recession formed therein, the recession being operable to receive a portion of a user's skin therein; ii) an orifice formed through the recession and through which a target area of the user's skin can be positioned, the recession being thereby operable to restrain a portion of the user's skin that is immediately adjacent the target area of the skin while leaving exposed through the orifice the target area of the user's skin such that a contact pad can make contact with the target area of the user's skin; a contact pad, positioned adjacent the orifice and being operable to engage the target area of the user's skin as the target area of the user's skin protrudes through the orifice; and an actuation system, operably coupled to one of: i) the contact pad and the ii) restraining system; the actuation system being capable of moving the contact pad and the restraining system relative to one another within a two-dimensional plane tangential to the target area of the user's skin to apply a shear force across the target area of the user's skin to thereby provide tactile information to the user.
