Image display device and input determination method

Abstract

An image display device includes an image display component, a detector, and an error determination component. The image display component is configured to project on a projection surface a projection image with at least first and second input objects for a user input operation using an indicator. The first and second input objects are adjacently arranged in the projection image with a spacing therebetween. The detector is configured to detect the indicator in a detection range that extends in a height direction of the projection surface. The error determination component is configured to determine that the user input operation of the second input object is erroneously detected in response to the detector continuously detecting the indicator in regions of the detection range corresponding to the first input object, the spacing and the second input object, respectively.

Dependencies are inferred from the claim text.
