Abstract

A handwriting support device includes a half mirror; an image display surface; a writing surface, a virtual image of an image displayed on the image display surface being projected on the writing surface. In a case where a real object is inserted onto the writing surface, the image display control unit causes a non-display processed image to be displayed on the image display surface, the non-display processed image being obtained by at least a partial region, of a region of the first image corresponding to a vertically projected region of the real object on the writing surface, being subjected to non-display processing. In the handwriting support device, an image, which is a virtual image of the non-display processed image in which at least a part of an inside of the vertically projected region of the real object is non-displayed, is projected onto the writing surface.

First claim

What is claimed is:

1. A handwriting support device, comprising:
a half mirror;
an image display surface positioned to face at a side of a mirror surface of the half mirror;
a writing surface positioned to face the image display surface with the mirror surface of the half mirror interposed therebetween; and
an image display control unit that causes a first image to be displayed on the image display surface,
wherein a virtual image of an image displayed on the image display surface is projected onto the writing surface, and
wherein, in a case in which a real object is inserted onto the writing surface, the image display control unit causes a non-display processed image to be displayed on the image display surface, the non-display processed image being obtained by at least a partial region, of a region of the first image corresponding to a vertically projected region of the real object on the writing surface, being subjected to non-display processing, whereby an image, which is a virtual image of the non-display processed image in which at least a part of an inside of the vertically projected region of the real object is non-displayed, is projected onto the writing surface.

2. The handwriting support device according to claim 1 , wherein the image display control unit includes an object position sensor that detects the real object on the writing surface, and creates the non-display processed image from image data of the real object acquired by the object position sensor and displays the non-display processed image on the image display surface.

3. The handwriting support device according to claim 1 , wherein the image display control unit causes an image to be displayed on the image display surface as the non-display processed image, the image being obtained by only a region, which is inside a position of a predetermined length from the region of the first image corresponding to the vertically projected region of the real object on the writing surface, being subjected to non-display processing.

4. The handwriting support device according to claim 2 , wherein the image display control unit causes an image to be displayed on the image display surface as the non-display processed image, the image being obtained by only a region, which is inside a position of a predetermined length from the region of the first image corresponding to the vertically projected region of the real object on the writing surface, being subjected to non-display processing.

5. The handwriting support device according to claim 1 , wherein the image display control unit overlays a second image, having a smaller display area than the first image, on the non-display processed image to display the second image on the image display surface.

6. The handwriting support device according to claim 5 , wherein the image display control unit causes the second image to be displayed on the image display surface such that at least a part of the second image overlaps with the partial region subjected to the non-display processing of the non-display processed image.

7. The handwriting support device according to claim 6 , wherein the image display control unit causes the entire second image to be overlaid and displayed on the partial region.

8. The handwriting support device according to claim 2 , wherein the image display control unit overlays a second image, having a smaller display area than the first image, on the non-display processed image to display the second image on the image display surface.

9. The handwriting support device according to claim 8 , wherein the image display control unit causes the second image to be displayed on the image display surface such that at least a part of the second image overlaps with the partial region subjected to the non-display processing of the non-display processed image.

10. The handwriting support device according to claim 9 , wherein the image display control unit causes the entire second image to be overlaid and displayed on the partial region.

11. The handwriting support device according to claim 3 , wherein the image display control unit overlays a second image, having a smaller display area than the first image, on the non-display processed image to display the second image on the image display surface.

12. The handwriting support device according to claim 11 , wherein the image display control unit causes the second image to be displayed on the image display surface such that at least a part of the second image overlaps with the partial region subjected to the non-display processing of the non-display processed image.

13. The handwriting support device according to claim 12 , wherein the image display control unit causes the entire second image to be overlaid and displayed on the partial region.
