Abstract: Optical sensors can be used for content generation using an input device without a touch sensitive surface. In some examples, the optical sensors can be used to detect characteristics of the input device including position, orientation, and/or motion of the input device. In some examples, some or all of the characteristics of the input device can be used in processing to generate content, including textual character input and three-dimensional objects. In some examples, the generation of content can use information from one or more additional sensors of the input device and/or from additional devices in combination with the characteristics of the input device based on the optical sensors.

Abstract: Systems and methods for tracking the position of a head-mounted display (HMD) system component. The HMD component may carry a plurality of angle sensitive detectors that are able to detect the angle of light emitted from a light source. The HMD component may include one or more scatter detectors that detect whether light has been scattered or reflected, so such light can be ignored. Control circuitry causes light sources to emit light according a specified pattern, and receives sensor data from the plurality of angle sensitive detectors. The processor may process the sensor data and scatter detector data, for example using machine learning or other techniques, to track a position of the HMD component. An angle sensitive detector may include a spatially-varying polarizer having a position-varying polarizing pattern and one or more polarizer layers that together are operative to detect the angle of impinging light.

Abstract: An optical method for identifying locations of objects in a plane, including serially projecting light beams along a detection area, from a plurality of locations along an edge of the detection area, whereby a reflective object inserted into the detection area reflects the projected light beams, directing the reflections of the projected light beams arriving at the edge of the detection area onto a plurality of light detectors, in a manner that maximizes amounts of reflected light arriving at the detectors when the light arrives at a particular angle in relation to the edge, and calculating two-dimensional coordinates of the inserted object in the detection area based on the particular angle and the outputs of the detectors.

Abstract: The invention provides an ambient light sensing device which receives at least one visible light image sensed by an image sensor. The ambient light sensing device includes an image sampling unit and an analyzing unit. The image sampling unit divides the visible light image into plural image blocks, extracts at least one sample data in each image block, and generates a comparison data according to a difference between the sample data extracted at different time points. The analyzing unit analyzes the comparison data and generates an output analysis signal accordingly.

Abstract: An information processing device includes: an acquisition unit that acquires inertial information from an inertial sensor provided in a controller; a detection unit that detects the controller from a captured image acquired through imaging by an imaging device; and a control unit that acquires a position of the controller on a basis of a position of the controller acquired in a past and the inertial information in a case where the controller is not detected from the captured image. The control unit controls a display to display a display item at a position based on the acquired position of the controller.
