Abstract
The present invention provides a tactile sensing device comprising a tactile sensing layer, a pressure adjusting unit, at least one pressure sensing unit and a control unit. The tactile sensing layer includes a plurality of elastic elements, each of which has an inner space. The pressure adjusting unit coupled to the tactile sensing layer functions to provide and control variation of the pressure in the inner space of each elastic element. The control unit is coupled to the air supply unit and the at least one pressure sensing unit. The control unit is capable of receiving sensing signal from the at least one pressure sensing unit. In addition, the present invention also provides an apparatus whose surface is covered by the tactile sensing device. With the foregoing disclosure, it is capable of detecting the location and magnitude of the force acted on the tactile sensing device disposed on the surface of the apparatus through sensing the variation of pressure occurred in the elastic elements. Meanwhile, it is also able to change the softness of the tactile sensing device by controlling the air pressure inside the elastic elements.
