TOUCHSCREEN WITH HAPTIC FEEDBACK

摘要

An apparatus including a processor and a memory including computer program code. The memory and the computer program code are configured to cause the apparatus to, for an array of capacitive touch sensors with a proximally positioned electrotactile layer, compare the capacitance associated with a capacitive touch sensor of the array against a respective detection threshold to determine whether or not a touch input has occurred at the capacitive touch sensor by a stylus in capacitive coupling proximity to the capacitive touch sensor. The detection threshold of one or more capacitive touch sensors of the array is set to be sufficient to inhibit the erroneous generation of a touch input signal at the one or more respective capacitive touch sensors caused by capacitive cross-coupling, via the electrotactile layer, to the capacitive touch sensor which is in capacitive coupling proximity to the stylus.
