A display panel includes a plurality of emission areas emitting light and a light blocking area at least partially surrounding the plurality of emission areas, a plurality of touch electrodes disposed in the light blocking area on the display panel to sense a touch, a wavelength absorption layer disposed on the plurality of touch electrodes to absorb light of a specific wavelength, a bridge electrode disposed on the wavelength absorption layer to connect adjacent touch electrodes among the plurality of touch electrodes to each other, and a code pattern having position information determined by a planar shape of the bridge electrode.

An electronic device having a noncontact input function is provided. The electronic device includes a display device and an input device and is capable of performing an input operation even without contact. The display device includes a light-emitting device and a light-receiving device in a display portion. The input device includes a light source. The light-receiving device has a function of detecting light emitted from the light source included in the input device. Infrared light that has substantially no spectral luminous efficacy is used as the light emitted from the light source included in the input device. Therefore, even irradiation of the display portion with the light at high luminance does not affect visual recognition of the display. This structure enables a noncontact input operation with respect to the display device.

A touch input device includes a communication module receiving external light characteristic information. A code detector emits infrared light and receives infrared light reflected from a display panel to detect code patterns of the display panel. A light emitting driver controls an infrared light emission operation of the code detector. A code processor modulates an emission control signal so that an infrared light emission characteristic of the code detector is changed according to a change in the external light characteristic information and controls driving of the light emitting driver.

An image processing method and apparatus for a smart pen, and an electronic device are provided in embodiments of the present disclosure, and belong to the technical field of data processing. The method comprises: monitoring a working state of a second pressure switch provided at a pen tip of a smart pen after a first pressure switch of the smart pen is in a closed state; controlling an image collection module on the smart pen to collect a reflected infrared signal from an area where the smart pen writes; performing feature extraction processing on an original image to obtain a feature matrix corresponding to the original image; determining, based on current load status of the smart pen, the number of convolutional layers used for convolution processing in parallel convolutional layers; and adding current time information to a trajectory classification result to form a time-ordered trajectory vector.

[Object] Provided is an information processing apparatus that is able to provide consistent image quality even if a distance from a display apparatus varies within a projection region. [Solving Means] The information processing apparatus according to an embodiment of the present disclosure includes a transformation matrix calculation section, a scale calculation section, and an input display generation section. The transformation matrix calculation section calculates a transformation matrix that converts the coordinates of an input position of an input device within a projection region projected from a display apparatus from the coordinates of an image coordinate system of a sensor apparatus having detected the input position to the coordinates of a screen coordinate system of the display apparatus. The scale calculation section calculates a scale correction value for a display mode of the locus of the input position in reference to distance information regarding the distance between the display apparatus and the input position. The input display generation section generates an input image depicting the locus of the input position through the use of the transformation matrix and the scale correction value.

Contactless operation of a medical device, such as a hemodialysis (HD) or peritoneal dialysis (PD) device, is provided via a mobile pointing apparatus and a receiving arrangement associated with the medical device. The mobile pointing apparatus includes a signal emitter for emitting an optical or electromagnetic signal, and the receiving arrangement associated with the medical device determines a pointing target of the mobile pointing apparatus relative to the medical device based on the signal emitted by the mobile pointing apparatus and triggers a function of the device based on the pointing target of the mobile pointing apparatus.

An image processing method includes displaying a first screen on a display surface, the first screen including at least a part of a drawing area in which at least one object image drawn by a user is arranged, excluding an area in which at least a part of an object image included in the first screen is arranged from the drawing area when an operation of erasing the at least a part of the object is received, and displaying a reduced screen on the display surface when an operation is received, the reduced screen being obtained by reducing a whole of the drawing area into a size of the display surface.

A projection control device that controls a projection portion which projects an image to a projection surface includes a ray position detection portion that detects an irradiation position of a ray irradiated on the projection surface, and a specific image superimposition control portion that superimposes a predetermined specific image on a region corresponding to the irradiation position in the image. In a state where the specific image is superimposed on a first region corresponding to a first position detected by the ray position detection portion in the image, the specific image superimposition control portion, in a case where the irradiation position moves out of a predetermined range including the first position, moves the specific image to a region corresponding to the irradiation position that has moved, and in a case where the irradiation position moves within the range, continues superimposition of the specific image on the first region.

A portable information handling system commands a stylus to vibrate to aid in location of the stylus. The stylus vibrates at a frequency selected from a range of plural frequencies based upon a distance between the portable information handling system and stylus so that an audible noise is generated by the stylus with sufficient sound to be heard by a user of the portable information handling system while minimizing stylus power consumption. In one embodiment, a haptic film at the stylus exterior surface generates an ultrasonic noise detectable by a microphone of the portable information handling system for determining a vector to the stylus.

The present disclosure provides systems and methods that include or otherwise leverage an artificial intelligence system and/or provide user interface mechanisms particularly suited for interacting and/or interfacing with an artificial intelligence system. A computing system can include a camera, a light-emitting device, and an artificial intelligence system that comprises one or more machine-learned models. The computing system can include a processor and one or more non-transitory computer-readable media that stores instructions that, when executed, cause the processor to obtain an image of a scene captured by the camera; generate an attention output that describes at least one region of the scene that includes a subject of a processing operation performed by the artificial intelligence system; and control the light-emitting device to emit light onto or adjacent a region of the scene that includes the subject of the processing operation performed by the artificial intelligence system.
