Abstract
A touch sensor system includes buses, a plurality of touch sensor devices disposed on the buses, and an information integrating device that is connected to all the buses and integrates information from the touch sensor device. The touch sensor device includes a sensor unit and a signal processing unit that transmits a sensor data signal generated by processing an analog sensor signal to the information integrating device through the bus. The signal processing unit includes a digital converting unit, a threshold evaluating unit that gives a start permission of the signal process when a sensor value exceeds a preset threshold, an ID adding unit that adds a transmitter identification number to the sensor signal, and a data transmitting unit that outputs the sensor data signal to a signal line of the bus. Fast responses are made possible without increasing the amount of data and host processing load while including many touch sensor elements.
