Abstract: A control method of an electronic device and an external control device are provided. The control method may control the electronic device through a non-contact method. The external control device includes a handheld electronic device and an arithmetic control device. The external control device obtains display specification information of the electronic device, and the handheld electronic device is adapted for performing an image capturing action on a control interface of the electronic device to obtain a captured image. The handheld electronic device receives touch information. The external control device calculates coordinate conversion information between the captured image and an image of the control interface of the electronic device according to the display specification information and the captured image, converts the touch information to generate converted touch information according to the coordinate conversion information, and executes a control action on the electronic device according to the converted touch information.

Abstract: A touch display apparatus including a body, a display module, a light control element, and a touch module is provided. The body has an opening. The display module is disposed in the body and is suitable for emitting a plurality of image beams toward the opening. The light control element is disposed to overlap the opening of the body and is suitable for reflecting the image beams coming from the display module to an imaging space to display an image frame of the display module. The imaging space and the display module are located on two opposite sides of the light control element. The touch module is disposed on one side of the light control element and is configured to recognize a touch operation of a user in the imaging space.
