Wearable Display Device with Movable Imaging Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display (HMD) systems face a challenge where flipping up the image display unit to improve the user's field of view results in a change in the camera's imaging range, causing the target subject to be deviated from the imaging range, which hinders remote assistance.
Innovation Solution
A wearable display device with a mounting unit, image display unit, frame, coupling unit, and image acquisition unit that allows the image display unit to be moved vertically, maintaining a stable imaging range by adjusting the imaging unit's position and acquiring images from specific portions of the original range, ensuring continuous accurate assistance during flip-up operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image display unit is flipped up to improve the user's field of view, then the field of view is improved, but the imaging range changes and the target subject deviates from the imaging range
Solution Approach 1:
The imaging unit is made movable relative to the frame through an imaging unit holder that can change its holding position. When the image display unit is flipped up, the imaging unit dynamically adjusts its position to track the target subject, maintaining stable imaging despite the structural movement of the display unit.
Solution Approach 2:
The system uses detection means to detect the position of the target subject and the state of the image display unit, then feeds this information back to the control means. The control means adjusts the imaging unit's position based on this feedback to ensure the target subject remains within the imaging range during flip-up operations.
2Productivity
If the image display unit is moved away from the eyes to improve work efficiency, then work efficiency is improved, but the position of the image display unit changes causing imaging range deviation
Solution Approach 1:
The imaging unit holder can dynamically change its holding position on the frame to compensate for the movement of the image display unit. This dynamic adjustment ensures that even when the display unit is repositioned for improved work efficiency, the imaging unit maintains accurate tracking of the target subject.
Solution Approach 2:
The patent replaces fixed mechanical mounting with a movable imaging unit holder that can be repositioned. This substitution allows the system to adapt to different display unit positions while maintaining imaging accuracy, rather than relying on a fixed mechanical arrangement.

AI summary
A wearable display device includes a mounting unit, an image display unit that displays an image, a frame that supports the image display unit, an imaging unit that is supported by the frame and that captures an external scene, a coupling unit that connects the frame and the mounting unit such that a position of the image display unit with respect to the mounting unit is changeable in a first direction, and an image acquisition unit that acquires a first image of the external scene from a range on one side in the first direction in an imaging range of the imaging unit when the position of the image display unit with respect to the mounting unit is changed from the one side to another side in the first direction.
