Abstract: A finger-touch tracking system is provided, including a magnet, a magnetic field sensing unit, and a computing unit. The magnet generates a magnetic field. The magnetic field sensing unit moves relative to the magnet, and has a substrate and a plurality of sensors disposed on the substrate. The sensors detect a magnetic flux density of the magnet, so as to generate a tracking signal reflecting a relative position of the magnet with respect to the magnetic field sensing unit. The computing unit receives the tracking signal via a network, and employs the received tracking signal as an input instruction upon the magnitude of the magnetic field.

Abstract: A distance-tracking touch detection controller operable to enable functions of an electronic device based on a user's gestures and location of touch on his own body. The distance-tracking touch detection controller comprises a distance meter and a control interface coupled with the distance meter. When user touches his own body, the distance meter detects the touched location or the trajectory of touched locations and generates a detecting signal. The control interface is coupled with the distance meter, and the control interface reads the detecting signal to generate a control signal. The control signal is operable to enable one or more functions of an electronic device. Moreover, a method of operating the distance-tracking touch detection controller is presented.

The multimedia apparatus, including a microprocessor, a memory device, a multimedia file input device, a network interface, an audio/video body-sensing input device, an audio/video body-sensing output device and a control device, presents a multimedia effect of a file to a user. The server, including a central processing system, a storage system, a communication system and a recognition system, accesses the file and determines whether the file satisfies a trigger condition to selectively output a special effect. When the file satisfies the trigger condition, the multimedia apparatus further superimposes the special effect to the file and presents the file together with the special effect to the user to provide a situation simulation effect.

Abstract: A method in a video playback system for playing a video with a specific playback speed in accordance with a video feature and a playback record is described. The system allows the playback record records a preceding playback speed corresponding to the video previously played to learn user preferences for a user. This makes the specific playback speed more suitable for the user without any adjustment. In addition, the system also allows the user input a resetting playback speed to actively adjust the specific playback speed if the original specific playback speed is not suitable for the user.
