Abstract
A touch display device (TDD) configured to function with a pointing device (PD), and a method of operating the TDD. The TDD has a processor that automatically determines if the PD is in contact with a touch display (TD) of the TDD or with a surface distinct from the TD. When the PD is in contact with the TD, a toggling signal from the PD may be received at the processor to toggle from a first input mode where a tip of the PD overlaps a visual element displayed on the TD, to a second input mode with the tip of the PD is spaced apart from the displayed visual element. When the PD is in contact with the distinct surface, the processor automatically selects a third input mode where a position of the PD on the distinct surface is reproduced as a position the sign on the TD.
