Abstract

A handheld electronic apparatus, an operating method thereof, and a non-transitory computer readable medium thereof are provided. The handheld electronic apparatus includes a sensor, a processing unit, and an interface. When the handheld electronic apparatus is moved from a first position to a second position, the sensor generates a plurality of sensed data. The processing unit calculates a movement direction and a movement distance according to the sensed data. The interface is connected to a computer having a monitor. The interface transmits a control signal to the computer. The control signal carries the movement direction and a movement distance so that the computer controls a cursor shown on the monitor to move from a first coordinate to a second coordinate according to the movement direction and a movement distance carried in the control signal.
