An interactive display system including a wireless pointing device, and positioning circuitry capable of determining absolute and relative positions of the display at which the pointing device is aimed. An error value between the absolute position and an estimated or actual relative position at the point in time of the absolute position is determined, and a compensation factor is determined from this error value that is applied to subsequent relative positioning results.

Absolute and relative positioning sensor fusion in an interactive display system

An interactive display system including a wireless pointing device, and positioning circuitry capable of determining absolute and relative positions of the display at which the pointing device is aimed. The pointing device captures images displayed by the computer, including one or more human-imperceptible positioning targets. The positioning targets are presented as patterned modulation of the intensity (e.g., variation in pixel intensity) in a display frame of the visual payload, followed by the opposite modulation in a successive frame. At least two captured image frames are subtracted from one another to recover the positioning target in the captured visual data and to remove the displayed image payload. Motion of the pointing device between the two frames is detected by relative motion sensors, and used to align the positions of the positioning targets in the captured images for those frames to improve the fidelity of the recovered positioning target following the subtraction.

Motion compensation in an interactive display system

Display systems and methods for mobile devices and mobile devices are disclosed. In one embodiment, a display system for a mobile device is provided. The mobile device is handheld and includes a primary display screen. The display system includes an auxiliary screen and a connecting device coupled to the auxiliary screen and attachable to the mobile device. An image from the mobile device is producible on the auxiliary screen. The display system is removable from the mobile device.

Display systems and methods for mobile devices

System and method for wirelessly providing multimedia. A system includes a headset and a wireless communications device. The wireless communications device controls the operation of the headset with transmissions over a first wireless network. The headset includes a first ear piece, a second ear piece, and a connecting piece. The first ear piece has a first speaker, a first network interface to send and receive transmissions over the first wireless network, a second network interface to receive transmissions over a second wireless network, and a connecting piece. The connecting piece is coupled between the first ear piece and the second ear piece. The connecting piece includes a wire to electrically couple the second ear piece, the first ear piece, and the second network interface and to receive transmissions over the second wireless network. The wire may be made to any length since it may be embedded inside the connecting piece.

System and method for wirelessly providing multimedia

An interactive display system including a wireless pointing device including a camera or other image capture system. Pairing of the pointing device is performed by a computerized display system displaying a visual pairing code at its display, for capture by the pointing device. The pairing code may be displayed in a form that is human-readable, human-perceptible but not human-readable, or human-imperceptible. In response to detecting the pairing code, the pointing device transmits a wireless signal to the computerized display system including the pairing code. If the pairing code received by the display system matches that originally displayed, the computerized display system authorizes the pointing device as a source of control signals in the graphical user interface manner. Various additional handshaking approaches in combination with the visual pairing procedure are disclosed.

Visual pairing in an interactive display system

An interactive display system including a wireless pointing device including a camera or other video capture system. The pointing device captures images displayed by the computer, including one or more human-imperceptible positioning targets. The positioning targets are presented as patterned modulation of the intensity (e.g., variation in pixel intensity) in a display frame of the visual payload, followed by the opposite modulation in a successive frame. At least two captured image frames are subtracted from one another to recover the positioning target in the captured visual data and to remove the displayed image payload. The location, size, and orientation of the recovered positioning target identify the aiming point of the remote pointing device relative to the display. Another embodiment uses temporal sequencing of positioning targets (either human-perceptible or human-imperceptible) to position the pointing device.
