Abstract: An electronic device includes a processor that acquires touch data values corresponding to different locations of a touch display, and identifies an island in the touch data that has touch data values acquired from adjacent locations of the touch display that indicate a potential touch. A first area of the island is determined from touch data values that exceed a first threshold value, and a second area of the island is determined from touch data values that exceed a second threshold value. If the first area is less than a multiple of the second area, coordinates of a location of the island are determined from the touch data values indicating the potential touch. If the first area is at least the multiple of the second area, coordinates of a location of the island are determined from the touch data values indicating the potential touch that exceed a third threshold value.

Abstract translation: 电子设备包括获取与触摸显示器的不同位置相对应的触摸数据值的处理器，并且识别触摸数据中具有从指示潜在触摸的触摸显示器的相邻位置获取的触摸数据值的岛。 从超过第一阈值的触摸数据值确定岛的第一区域，并且从超过第二阈值的触摸数据值确定岛的第二区域。 如果第一区域小于第二区域的倍数，则从指示潜在触摸的触摸数据值确定岛的位置的坐标。 如果第一区域是至少第二区域的倍数，则从指示超过第三阈值的潜在触摸的触摸数据值确定岛的位置的坐标。
