METHOD AND ELECTRONIC DEVICE FOR CARRYING OUT EDGE SUPPRESSION AND CORRECTION

摘要

An electronic device (“the device”) includes a touchscreen display that has a centroid within a curvilinear active area of the touchscreen display. The device detects a touch at a location on the touchscreen display and determines the length of a vector between the centroid and the location. If the length is less than a predefined threshold radius, the device carries out a function in response to the touch. If the length is greater than the predefined threshold radius, the device suppresses the touch. In some implementations, the device carries out edge correction by detecting that the touch is sliding towards an edge of an active area the touchscreen display and, if the length is greater than the distance between the centroid and a predefined edge threshold, the device processes the touch as if the touch was actually closer to the predefined edge threshold.

1. On an electronic device that includes a touchscreen display having a centroid within a curvilinear active area of the touchscreen display, a method for carrying out edge suppression, the method comprising:
detecting a touch at a location on the touchscreen display; determining a length of a vector between the location and the centroid; if the determined length is less than a predefined threshold radius, carrying out a function in response to the touch; and if the determined length is greater than the predefined threshold radius, suppressing the touch.
