Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing augmented reality display devices experience afterimages due to changing display positions, making it difficult for users to visually recognize navigation information.

Innovation Solution

A processor is configured to control the display of a second image to follow the change in relative position while keeping the first image stationary, ensuring minimal change or no change in its display position, and adjusting the second image to maintain visibility and connection with the first image.

1Measurement precision

If the display position changes according to user movement to maintain spatial accuracy, then navigation accuracy is improved, but afterimage occurs making visual recognition difficult

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The display image is divided into multiple regions: a first region with a first display position that remains substantially fixed, and a second region with a second display position that moves according to relative position changes. This segmentation allows different parts of the navigation information to serve different functions - the fixed region provides stability to prevent afterimage, while the moving region maintains spatial accuracy for navigation guidance.

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If the display position remains fixed to prevent afterimage, then visual recognition is improved, but spatial accuracy for navigation deteriorates

Engineering Contradiction:

Improveafterimage reductionVSAvoidspatial accuracy

Core Design Contradiction:

Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The display image is segmented into fixed and movable regions. The first region maintains a fixed display position to prevent afterimage and ensure visual recognition, while the second region adjusts its display position according to relative position changes to maintain spatial accuracy for navigation guidance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the display image are assigned different properties: the first region has fixed positional properties to prevent afterimage, while the second region has dynamic positional properties that respond to relative position changes. This local differentiation allows each region to optimize for its specific function.

AI summary

A processor (41) is configured to display a first display image that displays information related to an object existing in a real space and a second display image on a transmissive display device (10), change a display position of the second display image based on a change of a relative position between the display device and the object, and perform a control to make a change amount of a display position of the first display image smaller than a change amount of the display position of the second display image.
