Abstract
A computer system including an electronic device and an input device is disclosed. The electronic device includes a touch display area and a control unit. The input device includes a plurality of positioning structures and a grounding piece. The positioning structures are electrically connected to the grounding piece. When the input device is disposed on the touch display area of the electronic device, the control unit detects positions of the positioning structures on the touch display area, calculates a coverage area covered by the input device on the touch display area according to the positions, and determines a range of a display area of the touch display area according to the coverage area.
Claims5
An input device, applied in an electronic device, comprising:
- a casing, including a top plate, a bottom plate, and a grounding piece between the top and bottom plates;
- an input assembly, disposed on the top plate of the casing;
- and
- a plurality of positioning structures made of a conductive rubber, in direct physical contact with a bottom surface of the grounding piece and protruding downwardly from the grounding piece and penetrating through the bottom plate of the casing to an outside of the casing, wherein when viewed in a cross section, at least one of the positioning structures has a curved bottom surface;
- and
- a fixing structure comprising a magnetic material and protruding downwardly from a bottom surface of the bottom plate of the casing, wherein when viewed in the cross section, the fixing structure has a flat bottom surface level with a bottommost position of the curved bottom surface of the at least one of the positioning structures.
