Apparatus and method for controlling an electronic device with user
action
摘要:
An input unit for controlling a device. The input unit first determines whether a user is actively operating the device. If such a detection is made, the input unit then determines whether the user performs an act that corresponds to a command. User attention may be indicated by a user observing the device, approaching the device, facing the device, or speaking. An input command may be indicated by touch, gesture, speech, or line of sight.
