An inertial head-tracking system includes light emitting diodes (LEDs) and photoreceptors. The LEDs and photoreceptors are positioned around the environment and helmet respectively. A processor periodically receives measurements from the photoreceptors and resets inertial drift based on those measurements. Either the LEDs or the photoreceptors are constrained to a specified range to allow for more accurate drift estimation.

In some embodiments, a stylus device can be configured for use in an augmented/virtual reality (AR/VR) environment. The stylus device can be configured to be used differently in a right hand or a left hand of a user. Determination of whether the stylus device is used in the left hand or the right hand can be used to improve tracking of the stylus device for use as a control device for the AR/VR environment.

A head-worn computer includes a camera system positioned to capture a surrounding environment in front of a user, a processor that identifies a position of a plurality of light emitters mounted on a hand-held controller from images captured by the camera system and tracks the position of the plurality of light emitters as the hand-held controller moves in the surrounding environment and interprets the tracked position as positional changes of the hand-held controller. The processor uses the position of the plurality of light emitters as markers in three dimensional space, the markers used as an anchor for virtual content presented in a see-through display of the head-worn computer.

A modular interactive visual display platform including interconnecting modules including tile modules forming a visual display sensing surface which generates graphical images and senses object proximate to the surface. Tile connector interfaces use tricoupling mechanisms including a mechanical connector, a power connector and a communication connector to connect modules together. The visual display sensing surface may include integrated addressable LEDs, proximity sensors and pressure sensors.

An optical mouse includes a pixel array and a light source. A method for determining when the optical mouse is in a lifted condition above a surface includes: accumulating pixel values of a first column of the pixel array, the first column being closest to the light source; accumulating pixel values of a second column of the pixel array, the second column being different from the first column; comparing the accumulated pixel values of the first column with the accumulated pixel values of the second column; and when a difference between the accumulated pixel values of the first column and the accumulated pixel values of the second column is greater than a threshold value, determining the optical mouse to be in a lifted condition.

A touchless elevator call button selection device utilizing a plurality of infrared beams is disclosed along with its method of use. By using beams of light to detect the position of a user's hand, the touchless elevator call button selection device allows the user to interface with the elevator control system without physically coming into contact with the elevator control system.

A ubiquitous Network Platform/Computer Operating System where traditional screen displayed Control Icons are replaced with real world Virtual Reality “life like” 3D animations/simulations, all items within forming working Control icons connected to real time/spatial coordinates, the simulation being simultaneously updated by, but not limited to, iA and any/all connected service appliances, program applications, outside collected contributing data sources and any other I.O. forum.

An input device includes an optical sensor which senses an object on a plane where the emitted light travels, an optical member which changes a path of the light emitted from the optical sensor, and a processing unit which performs input processing based on sensing results of the optical sensor; the optical sensor and the optical member form a first sensing surface consisting of a planar region in which the light emitted from the optical sensor travels and a second sensing surface that is farther from the optical sensor than the first sensing surface, and the processing unit performs the input processing based on a first sensing result of the optical sensor on the first sensing surface and a second sensing result of the optical sensor on the second sensing surface.
