The present embodiment is an information processing device adapted to a non-contact user interface. The information processing device includes a display control unit configured to perform control such that a first screen is displayed on a display, a feature recognition unit configured to recognize a feature related to a specific part of a user in a spatial coordinate system, a mapping unit configured to specify a position on the first screen, the position corresponding to a position of the specific part in the spatial coordinate system, according to a mapping algorithm on the basis of the feature, an input operation specifying unit configured to specify an input operation on the basis of content of the first screen and the position on the first screen, and a processing execution unit configured to execute processing on the basis of the input operation. The mapping unit causes a reference trajectory to be displayed on the first screen under the control of the display control unit, and determines an optimal mapping algorithm on the basis of a user trajectory according to a motion of the user with respect to the reference trajectory.

Head worn computers may include two physically separated cameras mounted on a front surface that capture movements of a finger of the user of the head-worn computer. The head worn computer includes an image source adapted to display content in a see-through display of the head-worn computer, wherein the content is positioned to be perceived by a user as positioned on a surface proximate the head-worn computer. A processor of the head worn computer is adapted to develop a 3D model, based on the captured finger movements and the position of the content, describing an interaction of the finger with the content.

Provided are a projection apparatus and an interface apparatus that have a small size and low power consumption and can perform high-resolution multicolor display, without color breakup. The projection apparatus includes a light source emitting laser beams of a plurality of colors, a modulation means that has a phase-modulation-type modulation element including display regions corresponding to each color of the laser beams of the plurality of colors emitted from the light source and modulates incident laser beams, an unnecessary component removal means that removes the unnecessary components, which are generated by the modulation of laser beams of other colors mixed in the display regions corresponding to the laser beams of the plurality of colors, from the laser beams modulated by the modulation means using wavelength selection; and a projection means that projects light from which the unnecessary components have been removed by the unnecessary component removal means.

An input device includes an input area, an optical or capacitive sensor which includes a scan area, and an analyzing unit. The optical or capacitive sensor detects a surface structure of a finger touching the input area in the scan area. The input device operates in an identification mode where the surface structure located in the scan area is detected via the optical or capacitive sensor. The input device also operates in an input mode where at least a sub-area of the scan area is detected at least once via the optical or capacitive sensor and is analyzed by the analyzing unit so that the analyzing unit assigns at least one of a control function and a switch function to a relative movement of the surface structure in the sub-area.

Embodiments disclosed are directed to a computing system that performs steps for providing follow-the-leader tapping control signals to one or more tapping devices. The computing system captures an interaction between a first user device and a user of the first user device. The computing system then generates a tapping control signal configured to instruct a tapping device to interact with a second user device based on the captured interaction. Subsequently, the computing system transmits the tapping control signal to the tapping device.

Various embodiments for detecting and rejecting false, unintended rotations of rotary inputs of electronic devices are disclosed herein. In one example, an electronic device is provided with an optical detector that measures the distance between the electronic device and the wearer's forearm or hand, and when the distance is smaller than a threshold distance, the turns of the rotary input are false, unintended turns. In another example, a crown of a rotary input includes a plurality of capacitive sensors that detects the presence of a wearer's finger, which when absent, the turns of the rotary input are false turns. In another example, deflections or positions of a shaft of the rotary input are measured and if the deflections/positions indicate an upward force on the rotary input (which are likely caused by the wearer's forearm or hand), the turns of the rotary input are false turns. Other embodiments are described herein.

This disclosure generally relates to a system comprising a touch sensor on polymer lens and methods for manufacturing such system. The system comprises at least one polymer lens and at least one touch sensor. The system further comprises at least one frame and a base coat. This disclosure also relates to an optoelectronic system comprising the touch sensor on polymer lens.

Described methods and apparatus for a location determination and registration methodology for smart devices that involves creating a registration map of a bounded space, with various smart devices located therein in fixed positions, and for each smart device relative positions in which a gestural input device can communicate with it, and relative distances, signal strengths and the like associated therewith for each smart device being part of the registration map. Once created, the registration map can be used to allow for a particular smart device to communicate with the gestural input platform when that is intended and the two are properly oriented relative to each other.

An optical sensor includes light emitters, light detectors detecting an intensity profile of a light beam, focusing lenses refracting light beams onto the light detectors, diverging lenses, each light emitter emits light beams through a respective one of the diverging lenses, and the diverging lens refracts the light beam into multiple divergent light beams that each travel across a detection area and are each directed to a respective pair of the focusing lenses, wherein an intensity profile of each divergent light beam has maximum intensity along the center of the beam, and a processor receiving light profile outputs from the light detectors, and calculating a location of an object in the detection area based on comparing received outputs from two detectors that receive a common one of the divergent light beams partially blocked by the object.
