Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In head-mounted displays, inappropriate setting of the inter-lens distance can lead to blurred display for the user.
Innovation Solution
An information processing apparatus and method that generates an adjustment screen displaying lens and pupil images based on eye tracking results to assist in adjusting the inter-lens distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the inter-lens distance is not set appropriately, then the display becomes blurred for the user, but adding adjustment mechanisms increases device complexity
Solution Approach 1:
The system uses eye tracking to detect the user's pupil position and provides visual feedback through an adjustment screen showing the relationship between the pupil and lens images. This feedback loop enables the user to self-adjust the inter-lens distance without complex mechanical mechanisms, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The adjustment mechanism empowers the user to perform the adjustment themselves using the visual feedback from the adjustment screen. The user can independently set the correct inter-lens distance by aligning the pupil image with the lens image, eliminating the need for complex automated adjustment mechanisms.
2Measurement precision
If manual adjustment of inter-lens distance is provided, then setting accuracy can be improved, but the ease of operation decreases due to additional adjustment steps
Solution Approach 1:
The adjustment screen provides real-time visual feedback showing the pupil image and lens image alignment status. This immediate feedback guides the user through the adjustment process, making it intuitive and easy to perform while ensuring accurate setting. The user can see the effect of each adjustment and know when the correct position is achieved.
Solution Approach 2:
The system uses visual indicators including color-coded feedback to show whether the inter-lens distance is correctly set. The adjustment screen displays visual cues that change based on alignment status, making the adjustment process straightforward and reducing the cognitive load on the user.

AI summary
A computer-implemented method including displaying, on an electronic device, an adjustment screen that allows a user to adjust a distance of a lens of the electronic device. The adjustment screen includes a lens image associated with a position of the lens in the electronic device and an eye image associated with a position of an eye of the user. The method also includes changing, by the electronic device, a position of the lens image in the adjustment screen to an updated position of the lens image in response to the user adjusting the position of the lens in the electronic device.
