Control apparatus and electronic device using the same

A control apparatus comprising:

• a motion sensor attached to the head of an operator, for sensing head movements of the operator and generating sensing signals;
• an image acquisition device attached to the head of the operator and in front of the eye of the operator, for capturing images of the eye of the operator;
• and
• a processor for calculating a displacement of the motion sensor according to the sensing signals from the motion sensor, converting the displacement into displacement signals, analyzing the images to determine eyelid movements of the operator and generating activation commands according to the eyelid movements.
