ELECTRONIC DEVICE USING ELECTROMAGNETIC INPUT DEVICE

摘要

An electronic device includes an electromagnetic input device, a memory, and a processor. The electromagnetic input device includes a movable magnetized stylus and an inducting module. The inducting module includes a number of inducting cells and a controller. Each inducting cell includes a coil for generating an inducting voltage according to the change of magnetic flux through the coil. The controller determines the type of movement of the stylus according to the inducting voltages generated by the coils of the inducting cells. The memory stores a number of operating commands corresponding to a number of types of movements of the stylus. The processor generates an operating command for operating the electronic device corresponding to the type of movement of the stylus determined by the controller.
