Electronic device and method of processing user actuation of a touch-sensitive input surface

摘要

An electronic device includes a proximity-sensitive touch sensor array which extends along an input surface of the electronic device and a processing device coupled to the touch sensor array. The processing device is configured to process data captured by the touch sensor array to determine a finger angle at which a finger is directed towards the input surface and an actuation position on the input surface. The processing device is configured to establish an offset-corrected actuation position as a function of the actuation position and the finger angle.

1. An electronic device, comprising: a proximity-sensitive touch sensor array which extends along an input surface of the electronic device; a force sensor configured to determine a force with which a finger is pressed against the input surface or multiple fingers are pressed against the input surface; and a processing device coupled to the touch sensor array, the processing device being configured to:
process the data captured by the touch sensor array to determine a finger angle at which the finger is directed towards the input surface and an actuation position on the input surface, determine a position offset for the actuation position on the input surface as a function of the finger angle, establish an offset-corrected actuation position as a function of the actuation position and the position offset, and determine a force offset as a function of the finger angle, derive an offset-corrected force value from an output of the force sensor and the force offset.
