When position information is outputted, in a case where the correspondence between a first interface via which an image signal is inputted and a second interface via which the position information is outputted has not been stored, it is evaluated whether a candidate of the second interface is uniquely determined. When the candidate is not uniquely determined, an output destination identification image is displayed, and an output destination selected in the output destination identification image is stored in a management table. When the correspondence between the first interface and the second interface has been stored, it is evaluated whether a no output destination has been stored in the management table, and when the no output destination does not apply, the position information is transmitted.

An apparatus and methods for remote controlling of mouse cursor and imitating its function is disclosed. The apparatus comprises of a camera module, one or more processors, one or more memories, a communication interface, a switch for setting work mode and image processing programs stored in the memories. This apparatus has two working modes which are set by the switch: camera mode and mouse mode. In camera mode, the apparatus works as a regular digital camera. In mouse mode, the apparatus works with a laser pointer to play functions of a mouse. It captures the image of a target area which is overlaid with the beam spot of the laser pointer, then analyzes the trace pattern and detects the dynamic properties of the beam spot characterized by primary and secondary attributes, and further performs predefined mouse when communicating with a computer through wired or wireless communication.

An electronic device comprising a stylus; said stylus comprising a pointed end having a touch capable compression tip, and a top end, said top end comprising a rotatable element disposed of at the end of the top end, comprising a first electronic element mounted on said rotatable element, a second electronic element mounted below said rotatable element; a first contact point and a second contact point disposed on said stylus between said second electronic element and said pointed end; and at least one sensing button; said stylus comprising means for electronically communicating with said electronic device.

A digitizer system includes a substrate with indicia having photoluminescent features that uniquely define local areas of the substrate. A sensor device, such as a stylus, may sense radiation emitted from the features, and a controller may determine therefrom the location of the stylus relative to the substrate.

A both-direction display method includes: inputting an image signal from an external device; displaying an image on a screen on the basis of a display signal; detecting an operation for the screen as an image operation; drawing an operation input object corresponding to the image operation; outputting the display signal for displaying a composite image obtained by combining an external image on the basis of the image signal and the operation input object; detecting an interlocking operation; and editing the operation input object so as to follow a change of the external image in accordance with the interlocking operation.

A highly convenient display system is provided. A display system that enables a screen to be operated easily with a laser pointer is provided. A display system that enables a screen to be operated by a large number of people is provided. The display system includes a light-emitting apparatus and a display device. The light-emitting apparatus includes a means for emitting visible laser light and a means for emitting invisible light. The display device includes a display unit including a means for displaying an image and a means for obtaining positional information on a portion irradiated with the visible light, and a means for receiving the invisible light. The display system has a function of performing processing in accordance with the positional information when the invisible light is received.

A computing system for direct three-dimensional pointing includes at least one computing device, and a pointing/input device including at least one light source and a motion sensor module for determining absolute and relative displacement of the pointing/input device. At least one imaging device is configured for capturing a plurality of image frames each including a view of the light source as the pointing/input device is held and/or moved in a three-dimensional space. Two or more imaging devices may be provided. A computer program product calculates at least a position and/or a motion of the light source in three-dimensional space from the plurality of sequential image frames and from the pointing/input device absolute and relative displacement information, and renders on the graphical user interface a visual indicator corresponding to the calculated position and/or the motion of the light source. Methods for direct three-dimensional pointing and command input are described also.

Embodiments include a head-worn computer comprising, a front frame mechanically adapted to secure a see-through computer display; an arm, secured to the front frame, mechanically adapted to secure the front frame to the head of a user; and the arm comprising an internal speaker system, enclosed by the arm, wherein the internal speaker system comprises a back cavity and a speaker, the arm further comprising an inlet vent positioned to vent the back cavity and an audio outlet vent positioned to vent the speaker.

Aspects of the present invention relate to providing see-through computer display optics.

A stylus and touch sensitive device are disclosed. The stylus includes a stylus transmitter for transmitting a stylus signal. The touch sensitive device includes row conductors, each of which is associated with a row transmitter and a row receiver. The row transmitter is adapted to simultaneously transmit row signals, each on its associated row conductor, each of the row signals being orthogonal to each other of the plurality of row signals transmitted on each other of the row conductors. The row receiver is adapted to detect the stylus signal. Column conductors are provided, each associated with a column receiver that is adapted to detect the presence of each of the row signals transmitted by the row transmitter and the stylus signal.
