Abstract:
1. A method for classifying a movement of an object relative to a region of a touch-sensitive screen of a computing device, the region comprising a plurality of cells, the method performed by one or more processors and comprising: detecting a movement of the object relative to the region the touch-sensitive screen by, for one or more of the plurality of cells, (i) determining a first signal value corresponding to a first position of the object relative to the cell at a first time, and (ii) determining a second signal value corresponding to a second position of the object relative to the cell at a second time; calculating a velocity of the movement of the object based on the first signal value at the first time and the second signal value at the second time, the velocity having a magnitude and a direction; and classifying the movement of the object as either approaching or moving away from the region of the touch-sensitive screen based on at least the magnitude and direction associated with the velocity.
