Abstract: The invention discloses a control apparatus for a user to control an electronic apparatus. The control apparatus of the invention includes a monitoring module, a sensing module, a first processing module, and a first transmitting module. The monitoring module is used to monitor the user's eyeball(s), and generates related eyeball-movement information. The sensing module is used to monitor a body portion of the user, and generates related body portion-movement information. The first processing module is connected to the monitoring module and the sensing module respectively, for calculating the control information in accordance with the eyeball-movement information and the body portion-movement information. Additionally, the first transmitting module is connected to the first processing module, for transmitting the control information to the electronic device, which can act according to the control information.
