摘要： An electrostatic capacity type position detecting device having increased scanning speed is provided. The device includes a signal supplying electrode including a plurality of electrodes arranged in parallel with each other in a first direction, and a receiving electrode also including a plurality of electrodes arranged in parallel with each other in a second direction perpendicular to the first direction. A one-shot pulse having a predetermined time width is applied sequentially to the plurality of electrodes of the signal supplying electrode at a frequency equal to an integral multiple of 200 kHz. In other words, the sequential application of the one-shot pulse occurs with a time difference that is shorter than (e.g., 1/N of) the predetermined time width. A current change caused at rising and falling edges of the one-shot pulse is detected through the receiving electrode, to thereby indicate a position on the position detecting device.

摘要： A computer system displays an object on a touch surface and detects multiple touch points on the touch surface in proximity to the displayed object. Next, the computer system detects one or more touch point movements originating from one or more of the plurality of touch points and determines a type of sector in which each of the touch point movements enters. In turn, when one of the touch point movements enters a rotate sector, the computer system performs a rotate command on the object.

摘要： A position detecting device includes a position indicator (2), a first detection section (13) (e.g., an electrostatic capacity type detection section) having a substantially flat shape, and a second detection section (14) (e.g., an electromagnetic induction type detection section). The position indicator (2) has a coil (27). The first detection section (13) has, on one surface thereof, detection electrodes (15) for detecting a capacitance between itself and a human body part. The second detection section (14) is provided with loop coils (24) for detecting a magnetic flux G. Further, each of the detection electrodes (15) has a substantially flat shape, and is provided with at least one slit (19) extending from the outer edge to the inside. With such a configuration, not only can degradation of detection accuracy of the first detection section be prevented or suppressed, but also degradation of detection accuracy of the second detection section can be prevented or suppressed.
