Abstract
Disclosed herein is a touch screen controller operable with a touch screen. The touch screen controller includes input circuitry configured to receive touch data from the touch screen, and processing circuitry. The processing circuitry is configured to identify an island in the touch data, determine whether a horizontal groove is present in the island, determine whether a vertical groove is present in the island, and determine whether a diagonal groove is present in the island. The processing circuitry determines the island to indicate a single elongated touch where a diagonal groove is present in the island but horizontal and vertical grooves are not present in the island.
