Patent ID: 8368655

Claim:
An input device comprising: an input device body that encases the input device, the input device body having an operation surface on which an input operation is performed by a finger; a first detection means that detects a contact position of the finger on the operation surface; a second detection means that detects the movement of the input device body; a third detection means for detecting that the operation surface is pressed; a signal generating means that generates a signal that controls a screen displayed by a display device while being interlocked with the detection means; and a transmission means for sending the signal, which is generated by the signal generating means, to the display device, wherein the signal generating means generates a first signal for a first control of the screen where a detection result of the first detection means has been reflected when the detection of the contact position by the first detection means is performed without corresponding to the detection of the pressing of the operation surface by the third detection means, the signal generating means generates a second signal for a second control of the screen where detection results of the first and third detection means have been reflected if the duration of the detection of the pressing by the third detection means is shorter than a predetermined time when the detection of the contact position by the first detection means is performed corresponding to the detection of the pressing of the operation surface by the third detection means, and the signal generating means generates a third signal for a third control of the screen where a detection result of the second detection means has been reflected, as long as the detection of the pressing is continued if the duration of the detection of the pressing by the third detection means reaches the predetermined time when the detection of the contact position by the first detection means is performed corresponding to the detection of the pressing of the operation surface by the third detection means.
