Aerial video input device, program, and method

Abstract

To detect a touch and input operation to an aerial video without an optical system such as an infrared ray, and detect an input operation to a large sized aerial video and simultaneous touch to many points.SOLUTION: An aerial video input part 20 capable of performing an input operation to an aerial video 12a formed in an aerial space comprises; a video acquisition part 21 for acquiring a video of the input operation performed to the aerial video 12a, from a depth camera 14; an operation position detection part 22 for detecting a position on the video of the operation part performing an input operation, from the video acquired by the video acquisition part 21; an operation depth detection part 23 for detecting a depth in the video of the operation part performing the input operation, from the video acquired by the video acquisition part 21; and a coordination acquisition conversion part 24 for acquiring, on the basis of the detected position and depth of the operation part, the coordinate of the operation part in the video acquired by the video acquisition part 21, and converting the coordinate into a coordinate on the aerial video 12a. The aerial video input part is configured to output coordinate information on the aerial video 12a to a prescribed device.SELECTED DRAWING: Figure 1
