Abstract: The present invention provides an apparatus with surface information displaying, wherein a skin unit comprising a flexible display is covered on the surface of a moving object of the apparatus such that the surface of the apparatus is capable of displaying the information such us color, pattern or text immediately by software control. Meanwhile, the flexible display further has a layer of tactile sensing unit for detecting input of interacting signal. In addition, the moving object further integrates an environmental sensing device, an information identifying device or a combination of both and uses the environmental status, text information or audio/video, which are generated from the environmental sensing device or information identifying device, as an input signal through cable or wireless technology so as to generate responsive action through the flexible display or mechanism of the apparatus so that interactivities of the apparatus can be increased.

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.
