AR Glasses Imaging Range Guide With Motion-Based Display Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image capture devices mounted to XR glasses vary in resolution and mounting position, leading to discrepancies between the assumed and actual imaging ranges, which can hinder the acquisition of necessary captured images and potentially interrupt the user's field of view.
Innovation Solution
A wearable apparatus with a display device, image capture device, sensor, and controller displays a guide image indicating the outer edge of the captured image during a controlled display period based on sensor output, allowing the user to align the imaging range without prolonged interruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a guide image showing the outer edge of the imaging range is always displayed, then the user can understand the imaging range, but the field of view is interrupted for a long time and work is hindered
Solution Approach 1:
The guide image is displayed periodically rather than continuously. Specifically, it is shown at predetermined timings such as when the captured image changes or at intervals, allowing the user to understand the imaging range without prolonged interruption to the field of view. This periodic display resolves the contradiction by providing necessary information only when needed.
Solution Approach 2:
The display timing of the guide image is made dynamic and adaptive based on system state rather than fixed. The controller displays the guide image at predetermined timings determined by system conditions (e.g., when captured image changes, at regular intervals), making the information provision adaptive to actual usage patterns while minimizing field of view interruption.
2Loss of information
If the guide image is displayed frequently, then the imaging range information is provided adequately, but the display region is narrowed and work is hindered
Solution Approach 1:
Instead of continuously displaying the guide image (excessive action), the system displays it partially - only at predetermined timings when necessary. This partial display provides adequate imaging range information while minimizing the time the guide image occupies the display region, thus resolving the contradiction between information provision and display region availability.

AI summary
A pair of AR glasses is a display device of a transmission type mountable to a head of a user. An image capture device outputs a captured image obtained by capturing an image of an area in front of the user. An inertia measurement device detects a physical quantity concerning the movement of the head of the user. A display controller displays on the pair of AR glasses a guide image indicating an outer edge of the captured image, in a display period from a start timing to an end timing determined based on at least an output signal from the inertia measurement device.
