摘要： An indicator position detecting device and method are provided, which allow accurate position detection without the influence of noise in detection of the position of an indicator (e.g., a finger, a stylus pen) by a capacitive coupling system. To a conductor pattern in which plural conductors for signal transmission and plural conductors for signal reception intersect with each other, signals with frequencies different from each other are simultaneously supplied to the plural conductors on the transmission side, and signals of respective frequencies corresponding to the plural signals with the different frequencies are detected on the reception side, to thereby detect the position of an indicator on the conductor pattern. The amount of noise of each of the detected frequencies is detected. Any frequency that cannot be properly detected due to noise is switched to another frequency, and detection is carried out based on the newly selected frequency.

摘要： The invention relates to a point detecting device and a method for providing coordinate information which is indicated by a pointing device. This point detecting device is adapted for a large scaled system which is required to be operated at a low cost and at high accuracy. The point detecting device transmits signals from both ends of the loop coil arrangement towards the pointing device, and/or receives at both ends the signals generated by the electromagnetic function between the loop coil arrangement and the pointing device. The errors owing to the variations caused in the signal level and phase in response to the propagation constant of the loop coil arrangement can be reduced by adding the received signal pair.
