Abstract

Provided is a technology of projecting bright images at one time in a plurality of directions by means of a projector which is small and light weight. An interface apparatus is provided with: a laser source that radiates laser light; an element that modulates the phase of inputted laser light, and outputs the light; an image unit that captures a subject; and a control unit, which detects the subject captured by means of the image unit, determines, based on the results of the recognition, an image to be formed based on the light outputted from the element, and controls the element such that the determined image is formed.

Claims

5. The interface apparatus according to claim 2, wherein

the element includes a substrate and a plurality of mirrors,

each of the plurality of light-receiving regions of the element is configured by the mirror, and

the controller controls a distance between the substrate and the mirror.

6. The interface apparatus according to claim 1, wherein

the element emits the laser light such that the determined image is formed over one or a plurality of partial regions of a region over which the imaging device captures.

7. The interface apparatus according to claim 1, wherein

the element emits the laser light such that the determined image is formed over the subject captured by the imaging device.

8. The interface apparatus according to claim 7, wherein
