Abstract

The invention relates to a cursor display device and a cursor display method. A recognizing process in which an indicated first position is recognized on a display screen projected and displayed by a projector and a controlling process in which control is performed so as to display a cursor associated with the indication in a second position on the display screen are provided, and the cursor is displayed in the second position such that the cursor is displaced from the first position by a predetermined distance.

Description

Technical field [0001] The invention relates to a cursor display device and a display method thereof. Background technique [0002] In the past, it is known to use a projector to project an image displayed on the display part of a computer terminal on the screen, and to indicate the image projected on the screen by using the camera to detect the pen used by the user, and compare it with the image projected on the screen. Overlapping, a technique of displaying a cursor at the position of the detected pen (for example, refer to Patent Document 1) [0003] Patent Document 1: Japanese Patent Application Publication No. 2005-234368 [0004] However, in the technique described above, that is, in the conventional interactive system (unit) with a hovering function, there is a problem that the cursor is hidden and displayed by a part of the pen, making it difficult to observe the cursor. Summary of the invention [0005] The present invention has been completed in view of such circumstances,...
