Image display device
First Claim
1. An image display device comprising:
- an image display component;
a projection component including an optical element that forms an optical image in midair, the optical image corresponding to an image displayed by the image display component;
a distance measurement component having a detector that detects an indicator for performing an touch operation relative to the optical image to acquire distance information from the detector to the indicator;
a main body that supports the image display component, the projection component and the distance measurement component to change a position of the optical image in midair; and
a controller that determines whether or not the indicator has performed the touch operation relative to the optical image based on the distance information and relative movement information between the distance measurement component and at least one of the image display component and the projection component;
wherein the image display component and the projection component are relatively movable with respect to each other, andthe controller determines whether or not the indicator has performed the touch operation relative to the optical image based on the distance information and relative movement information between the image display component and the projection component.

Abstract
An image display device includes an image display component, a projection component that forms an optical image corresponding to an image displayed by the image display component, a distance measurement component having a detector that detects an indicator for performing an touch operation relative to the optical image to acquire distance information from the detector to the indicator, and a controller that determines whether or not the indicator has performed the touch operation relative to the optical image based on the distance information and relative movement information between the distance measurement component and at least one of the image display component and the projection component.

19. An image display device comprising;
-
an image display component; a projection component that forms an optical image corresponding to an image displayed by the image display component; a distance measurement component having a detector that detects an indicator for performing an touch operation relative to the optical image to acquire distance information from the detector to the indicator; a controller that determines whether or not the indicator has performed the touch operation relative to the optical image based on the distance information and relative movement information between the distance measurement component and at least one of the image display component and the projection component, a second detector that detects movement of the indicator with respect to a detection plane that is set at a position away from the optical image, the controller determining whether or not to perform an error notification based on the movement of the indicator upon detecting deviation between a position of the indicator on the optical image and an input acceptance region of the optical image, the controller performing the error notification upon determining that an operation in which the indicator moves out from the detection plane without moving into the optical image is performed at least a specific number of times after the indicator moves into the detection plane.
