Aerial drawing program

Abstract

We provide an aerial drawing program that allows you to freely draw in empty space with your fingertips. [Solution] A motion sensor installed in the aerial image display device detects the coordinates of the user's fingers in the vicinity of the aerial image area. Based on these finger coordinates, the trajectory of the user's fingertips is drawn in the aerial image area. The drawing is displayed in the aerial image area as an orthographic projection of the fingertips' trajectory onto the aerial image area. If the finger coordinates acquired by the motion sensor indicate a predetermined finger shape, the drawing in the aerial image area is erased along the trajectory of the user's fingertips. The aerial image display device is implemented, for example, using a recurrent transmissive optical imaging element.

Claims

1. A program executed on an aerial image display device comprising a computer, an image system controlled by the computer that projects images into the air, and a motion sensor that detects the coordinates of a user's fingers in the vicinity of the aerial image area projected by the image system and transmits the detection results to the computer, wherein the computer... The steps include obtaining the coordinates of the user's fingertip from the motion sensor, The system performs the following steps: using the coordinates of the fingertip acquired by the motion sensor, it draws on the aerial image region in accordance with the movement of the user's fingertip; In the step of performing the drawing, the trajectory of the user's fingertip is drawn in the aerial image area. The drawing step is performed when the coordinates of the fingers acquired by the motion sensor correspond to a predetermined finger shape. An aerial drawing program characterized in that, when the coordinates of the fingers acquired by the motion sensor correspond to a different finger shape than the predetermined finger shape, the drawing of the aerial image region is erased along the trajectory of the user's fingertip.

2. The aerial drawing program according to claim 1, characterized in that in the step of performing the drawing, an orthographic projection of the fingertip's trajectory onto the aerial image region is drawn.
