An input apparatus includes: a light source that emits detection light toward a first direction, and raster scans a detection interface defined in space, with the detection light; a first light sensor that is disposed closer to the light source than the detection interface, and detects first reflected light which is the detection light that has been reflected; a second light sensor that detects second reflected light which is the detection light that has been reflected off an instructing body that has entered a detection region extending from the detection interface toward the light source; and a control unit that detects a coordinate value of the instructing body using received-light data obtained by the first light sensor and the second light sensor receiving light at the same timing.

A device and a method for a human machine interface (HMI). The HMI device includes a dome having a hemispherical shape, a base attached to the dome forming an inverted cup like structure with a hollow interior, a chip scale lidar attached on the base and positioned to scan for a motion of an object external to the dome, at least one haptic device attached to the base and connected to the dome, and an HMI controller configured to send and receive signal from the chip scale lidar, detect and recognize a gesture based on the signal from the chip scale lidar, and activate or deactivate the at least one haptic device.

A scanning display system includes hybrid data acquisition. Data can be acquired in a time-of-flight mode, or in a non-time-of-flight mode. Infrared light pulses may be used in both modes. The infrared light pulses may have different characteristics. Time-of-flight data acquisition and non-time-of-flight data acquisition may be used sequentially or simultaneously.

This projector includes a laser beam generation portion, an image projection portion including a scanning portion and projecting an image on a projection area, a beam receiving portion receiving the laser beam reflected by a detection object and a control portion detecting an operation performed on the projected image with the detection object on the basis of the moving state of the detection object.

A touch panel system includes micro-electro-mechanical system (MEMS) groups. Each group includes an emitter producing a beam, and a MEMS mirror located about a corner of a touch panel screen. The MEMS mirror reflects the beam to create a beam sweep across a touch panel surface. An array of photo sensors is located parallel to an edge of the touch panel screen to detect reflected beams from an object about the touch panel surface. Based on when the reflected beams are detected, the angular positions of the MEMS mirrors can be determined and correlated to the object's position.

A projector includes a laser beam scanning portion, a light detecting portion, and a control portion performing control of predicting a prediction region where a detection object exists on the basis of detection of the detection object, changing a modulation pattern of a laser beam when the laser beam is scanned on the prediction region, acquiring the position of the detection object on the basis of reflected light of the laser beam emitted in a detection object detection pattern, and setting the position of the detection object to an indication position.

Systems and methods for determining a location of a stylus on a planar surface are provided. In one example, a system includes a first optical source, a second optical source, a stylus, and electrical circuitry. The optical sources are at source locations and configured to rotationally sweep optical beams along the planar surface. The optical beams include encoded data sequences that vary with time. The stylus contains at least one optical receiver and is configured to receive the optical beams. The stylus is also configured to detect the data sequences from the optical beams. The electrical circuitry is configured to determine angular relationships between the stylus and the source locations based on the detected encoded data sequences. The electrical circuitry is also configured to calculate coordinates of the stylus on the planar surface based on the angular relationships and the source locations.

A spatial input device includes a light beam scanner that emits light beams toward a spatially projected image while scanning the light beams, a photodetector that detects the light beams that have been reflected by an input object within a detection range, and a controller that counts a scan line number indicative of a number of the light beams that have been detected by the photodetector, and detects a position of the input object according to the counted scan line number using a table that specifies correlation between positions of the input object and scan line numbers.

An input device is provided that comprises a display component, a detector, and a controller. The display component displays an image. The detector detects a first motion and a second motion. In the first motion, a pointer is slid over a first operation screen that lies in an imaginary plane including at least part of a spatial image that is a virtual image of the image formed in space. In the second motion, the pointer is moved into a second operation screen that lies in the imaginary plane and is different from the first operation screen. The controller executes a first operation to select the image when the first motion is detected, and executes a second operation to execute content of the selected image when the second motion is detected.
