Abstract

An input inducing device is provided. The input inducing device includes a winding, a current sensor, and a processing unit. Two ends of the winding are connected to the current sensor and form a closed-loop with the current sensor. When a magnetic object moves towards the winding, the winding cuts magnetic induction lines of the magnetic object to generate an induced current, the current sensor senses the induced current and generates a sensing signal according to the sensed induced current. The sensing signal is transmitted to the processing unit, which then implements a predetermined function according to the sensing signal.
