Title:
CONTACTLESS INPUT DEVICE AND CONTACTLESS INPUT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/181237
Kind Code:
A1
Abstract:
A contactless input device (100) comprises: a three-dimensional operation coordinate detection unit (112) that detects a plurality of three-dimensional operation coordinates by sequentially detecting three-dimensional operation coordinates that are three-axis coordinates of a command input object, which is an object that inputs a command, in a predetermined space; a smoothing processing unit (113) that calculates smoothed three-dimensional operation coordinates by performing smoothing using a first number of three-dimensional operation coordinates among the plurality of three-dimensional operation coordinates, the first number being a predetermined number equal to or larger than two; and an airspace reception range passage determination unit (115) that uses the smoothed three-dimensional operation coordinates to identify passage coordinates that are coordinates through which the command input object has passed through an airspace reception range, the airspace reception range being a range defined in advance in the predetermined space.
