Abstract: A light guide plate guides light from a light source to form an image in a space. A sensor detects an object in the space including an imaging position of the image. Based on an output from the sensor, a controller acquires at least one of a trajectory of a plurality of positions where the object is detected, a duration time of detecting the object, or a number of times the object is detected as an input parameter. The controller identifies an input pattern according to a movement of the object based on the input parameter, and outputs a signal corresponding to the identified input pattern.

Abstract: To effectively concentrate particles in a detection area serving as the measurement center of a sensor. A particle sensor is provided with an enclosure; a detection area inside the enclosure, and a guide path in the enclosure, configured to guide a gas to a detection area. The cross-sectional perimeter in a direction perpendicular to the extending direction of the guide path gradually becomes smaller from an inlet to the guide path toward the detection area.
