Presented are systems and methods for controlling a PC from an interactive TV display. The system includes a network which interconnects a TV set-top-box (STB) to a PC. The STB includes a network interface so as to communicate with the network, a remote control receiver, a display controller, and a CPU. A remote control transmits a user's commands to the remote control receiver in the STB, which forwards the commands to a client software application resident in the PC. The client software interprets the commands and causes the PC to perform various programmatic steps. Images of the PC screen display are sent across the network to the STB from the PC by the client software application, where the display controller displays these images on the TV. An interactive virtual mouse, controllable by commands transmitted from the remote control, is superimposed on the images being displayed on the TV.

A method and system is disclosed for synchronizing the virtual and physical mouse cursors of a local computer and a remotely controlled computer. Video signals generated by a host computer are transmitted to a client computer in order to allow the user of a client computer to have a virtual presence on the host computer. However, the signals transmitted by the host computer may contain errors that can cause a physical mouse to lose synchronization with a virtual mouse. Therefore this virtual presence architecture uses USB protocol and human interface descriptors that support the movement of a mouse to an absolute position in order to synchronize a virtual mouse cursor with a physical mouse cursor.

A glove-like apparatus mounted on a user's hand to control the cursor movement and to click for providing functions of a computer mouse. The apparatus has a glove-like body with multiple finger tubes. A tilt sensor is mounted on the glove metacarpus, of which the roll angle of the hand is detected to determine the moving orientation of the cursor. Two pairs of bending sensors are mounted on the thumb tube and the index finger tube, each pair of the sensors is used to detect a bending angle of the corresponding finger. The bending of the thumb or the index finger at a time is used to move the cursor in the negative or the positive direction along the located orientation line. The data glove for cursor control is operated as a virtual mouse with a virtual tracking ball.

A virtual mouse device is preferably installed in a gaming machine, and serving as an input device. An image sensor unit is laminated on a specific area on a screen of a display unit, and detects fingers or a palm of a player that move on or over the specific area. The virtual mouse controller unit monitors the fingers or palm, and causes a virtual mouse to follow the fingers or palm within the specific area. If the fingers or palm moves out of the specific area, the virtual mouse controller unit then returns the virtual mouse to a default location. An input unit monitors the motion of the virtual mouse, and causes the display unit to move a mouse pointer on the screen depending on the amount and direction of travel of the virtual mouse.

An ultrasonic device determines a position of a user-controlled object within a virtual mouse region. The ultrasonic device includes an ultrasonic transmitter, spatially separated ultrasonic receivers and a processor. The ultrasonic transmitter produces an ultrasonic pulse and radiates the ultrasonic pulse into the virtual mouse region. The ultrasonic receivers receive a reflected ultrasonic pulse reflected from the user-controlled object within the virtual mouse region and produce respective reflected ultrasonic signals in response thereto. The processor determines the position of the user-controlled object within the virtual mouse region based on the reflected ultrasonic signals, and generates a position signal indicative of the position.
