Abstract
A hands-free control method for an electronic device requires a display device, a storage device, and a camera in the device. The method includes capturing an infrared image of a user's eye and a direction of gaze of a user's eye being analyzed according to the captured infrared image to determine a focus of the eye on the display device. Movements of the focus on the display device according to a previous position and a current position of the focus of the eye can be analyzed. A control instruction is generated according to a relationship between control instructions and eye movements and voice instructions can be generated based on received voice command from the user. The display device is controlled to perform predetermined actions when the voice instruction matches with the control instruction.
