Analysis Bluetooth signal (for example, distributes to the pen for creating particular color to extract including the identification information in Bluetooth signal
Identification code), and can perform function corresponding with the identification code extracting.
If electromagnetic wave is not sensed by second sensor 130, controller 140 passes through first sensor 120 acquisition and touches
Touch coordinate.Specifically, if electromagnetic wave is not sensed by second sensor 130, controller 140 can be based on from the first sensing
The touch signal that device 120 receives to obtain object touch coordinate.
On the other hand, if first sensor 120 is IR sensor and electromagnetic wave is not sensed by second sensor 130
Arrive, then controller 140 can execute difference in functionality according to touching the region being sensed.Specifically, controller 140 can basis
The size being sensed the region of touch by first sensor 120 is corresponding come the touch to execute to sensed by second sensor 120
