A projector can include a projection section that projects an image on a projection surface, a detection light radiation section that radiates detection light in a direction corresponding to the projection surface. The projector can also include an adjuster that adjusts the direction of the detection light relative to the projection surface, and an imager and a controller that can detect reflected light resulting from the detection light to detect operation performed on the projection surface. The controller can evaluate whether or not the detection state of the reflected light corresponds to a specific state. If the detection is in the specific state, the adjuster can adjust the direction of the detection light based on a result of the evaluation.

The invention relates to an actuation device (10) comprising: detection means configured to supply a position of an object interfering with at least one electromagnetic field; a means for determining a speed of motion of the object according to the position of the object supplied by the detection means; and actuation means configured to actuate an action if: the detection means supply a position of the object, and the speed of the object is lower than a predefined speed value.

An under display light field sensor is for sensing a fingerprint or touch on or in proximity to a display panel. The under display light field sensor includes a light-field image sensor and a plurality of micro-lenses on the subarrays of the sensing pixels. The light-field image sensor includes a plurality of subarrays of sensing pixels under the display panel. The sensing pixels in an identical one of the subarrays are configured to capture images of an object on or in proximity to the display panel by sensing lights from different directions. Each of the micro-lenses corresponds to one of the subarrays of the sensing pixels.

An apparatus includes a display stack comprising at least one layer to generate a digital display image. A front stack includes a position encoded contrast layer to provide a pattern of light in response to non-visible light applied to the position encoded contrast layer. The pattern of light encodes spatial information across a surface of the position encoded contrast layer. A hot mirror reflects the non-visible light applied to the position encoded contrast layer of the front stack and is optically transparent to visible light generated from the display stack.

Provided is an infrared reflective patterned product including: an infrared reflective pattern portion which includes an infrared reflective material in a region constituting at least a part of a support, in which the infrared reflective pattern portion has an uneven structure that includes a plurality of protruding portions and/or recessed portions, metal particles are contained on surfaces of the protruding portions and/or recessed portions of the uneven structure of the infrared reflective pattern portion, the metal particles include 60 number-percent or greater of tabular metal particles in a hexagonal shape or a circular shape, and the tabular metal particles which are plane-oriented so that an angle between a principal plane of the tabular metal particle and a surface of the uneven structure closest to the tabular metal particle is in a range of 0° to ±30° are adjusted to be 50 number-percent or greater of all tabular metal particles. In the infrared reflective patterned product, the ratio of the reflectance of the infrared reflective pattern portion at a wavelength with the highest reflectance in an infrared region of 780 nm to 2500 nm to the reflectance of a non-pattern portion is large in a case where the infrared reflective pattern portion is obliquely irradiated with infrared rays.

A virtual input device for a mobile phone is revealed. The virtual input device includes a housing for stable placement on a flat surface, a mobile-phone mounting member that allows the mobile phone used able to be mounted thereon horizontally or vertically, and a virtual input module wirelessly connected to the mobile phone for generating a virtual input image having virtual input function and a larger area than the screen of the mobile phone. Thereby users can complete input to the mobile phone or control mobile games by the virtual input image.

A flexible touch surface, emitters projecting light beams across the surface such that the beams are incident upon and reflected by the surface when crossing the surface, detectors detecting reflections, by an object on the surface, of projected beams, lenses oriented such that there is a particular angle of entry at which each detector receives a maximal light intensity when beams enter a lens corresponding to the detector at the angle of entry, and such that there are target positions on the surface whereby for each emitter-detector pair, when the object is located at a target position associated with the pair, then light beams emitted by the emitter of the pair are reflected by the object into the lens corresponding to the detector of the pair at the angle of entry, and a processor synchronously co-activating emitter-detector pairs and calculating a location of the object on the surface.

A method and apparatus for inputting data for an electronic data entry device are provided. In one embodiment, identification of an input object such as the particular fingers of a user that are used to actuate a key region is performed. The symbol associated with the actuated key region and the finger (or other input object) used is determined. In other embodiments, virtual input devices with interfaces such as QWERTY style keyboards, phone keypads, and multi-touch capable touchpads or tablets are provided in input regions. One or more video capturing devices remotely acquire actuation information from the input regions during data entry. User inputted symbols or functions are determined based on the actuations, their locations and identified input object sets that caused the actuations.
