Abstract

A manipulation input device includes a projection component, a photodetector and an inclination determination component. The projection component projects an image on a projection surface by scanning light from a light source. The photodetector detects as scattered light the light reflected by a manipulation object. The inclination determination component acquires, for a plurality of scan lines of the light, position information of the manipulation object that is specified based on scanning angle information when the photodetector has detected the scattered light, and width information of the manipulation object that corresponds to a continuous detection duration during which the photodetector continuously detects the scattered light. The inclination determination component determines inclination of the manipulation object based on at least one of a temporal change in a plurality of sets of the width information and a temporal change in a plurality of sets of the position information.
