AUTOMATIC AND DYNAMIC SENSITIVITY CONTROL OF PROJECTED CAPACITIVE TOUCH SENSITIVE DETECTION SYSTEMS

Systems and methods of controlling the touch sensitivity of a projected capacitive touch detection system are provided. The temperature that is at least representative of the touch sensitive region temperature is sensed. Based on the sensed temperature, the numbers of the capacitive touch sensors th...

Zusammenfassung:Systems and methods of controlling the touch sensitivity of a projected capacitive touch detection system are provided. The temperature that is at least representative of the touch sensitive region temperature is sensed. Based on the sensed temperature, the numbers of the capacitive touch sensors that have different strength electric fields applied thereto are varied and/or the relative magnitudes of the different electric fields are varied. When installed in a vehicle, the operational state of the vehicle may also impact this operation.
