Abstract

Techniques for hard press rejection are described herein. In an example embodiment, a touch area on a sensor array is determined, where the touch area corresponds to a detected object and is associated with multiple signal values. A slope value for the detected object is computed based on a ratio of a signal distribution value in the touch area to a metric indicating a size of the touch area with respect to the sensor array. The slope value is compared to a threshold in order to determine whether to accept or to reject the detected object, and the detected object is rejected based on the comparison.
