Abstract: A method for recognizing a human hand comprises: recognizing a human body target by using a plurality of frames of detection information acquired by a millimeter wave radar within a preset time period; determining whether a new detection target satisfying setting conditions exists within a preset range centering on the human body target, according to a current frame of detection information, the setting conditions including: having a radial velocity; if so, determining the new detection target satisfying the setting conditions as a hand corresponding to the human body target; and if not, determining that the hand corresponding to the human body target does not exist in the current frame.

Abstract: A gesture recognition apparatus, a gesture recognition method, a computer device and a storage medium are disclosed. The gesture recognition apparatus includes a controller, a first distance sensor and a second distance sensor, wherein a first measurement area of the first distance sensor partially overlaps a second measurement area of the second distance sensor; and the controller is configured to recognize a gesture to be measured according to a first trajectory and a second trajectory as well as a position relationship between the first distance sensor and the second distance sensor.

Abstract: A translator pen and a translation method using same are provided. The translator pen includes a housing and a pen head. The housing forms a first accommodation cavity adapted to accommodate an image collector. An outer contour of the pen head is formed into a tapered shape, an outer diameter of the pen head gradually decreases along a direction of the pen head away from the housing and forms a second accommodation cavity adapted to accommodate a pen core. At least a portion of the end of the housing, which does not form the pen head, forms an inclined surface. The inclined surface is inclined relative to the outer contour of the pen head toward an outside of the housing along a direction of the housing away from the pen head. The image collector is configured to face the inclined surface.

Abstract: Disclosed are a display device and a control method. The display device includes: a transparent substrate; a transflective film disposed on a first side of the transparent substrate; a display screen disposed on a second side of the transparent substrate, the first side being opposite to the second side; and an infrared gesture recognition circuit disposed on the second side of the transparent substrate, where an orthographic projection of the infrared gesture recognition circuit on the transparent substrate and an orthographic projection of the display screen on the transparent substrate do not overlap each other; and the infrared gesture recognition circuit is configured to recognize a gesture at a side of the transflective film and control interface display of the display screen according to the determined operation gesture.
