Handheld electronic device and remote control method

摘要

A handheld electronic device and a remote control method are provided. The handheld electronic device comprises a display unit, an electronic compass and a processing unit. The reference locations are correlated with the controlled device. The processing unit constructs the coordinate system and calculates the reference location coordinates for the reference locations in the coordinate system. After the coordinate system is constructed, the electronic compass measures the current direction information directed towards the controlled device to be remote controlled from a current location. The processing unit controls the display unit to display a control interface of the controlled device to be remote controlled. The electronic compass measures origin direction information directed towards at least two reference locations from an origin location and measures move direction information directed towards the reference locations from a move location.
