Abstract: An electronic system includes a device having a screen and an optical touch device. The optical touch device monitors the activity of an object on the screen of the device. When the object performs an operation in a first region of the screen, the optical touch device generates first data; and when the object performs an operation outside the first region, the optical touch device generates second data, wherein the first data and the second data are of different data types.
