<p>An information device, a control method thereof and a system are provided. A target system is controlled based on detecting and tracking a user's hand. With this method, a live video captured by a camera can be automatically analyzed. The user's hand can be detected from the video. The user's hand is tracked and its movement trace is recorded. It is possible to recognize, based on the movement trace, whether the user has issued a signal and what the signal is issued. The recognized signal is then converted into a command executable by the target system. In this way, the user can control a contact-less system with hand wave gesture.</p> |
