Eye-Tracked Inter-Lens Adjustment Screen for Clear Headset Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In head-mounted displays, an improperly set inter-lens distance can cause blurred display for the user.
Innovation Solution
An information processing apparatus generates an adjustment screen with lens and pupil images based on eye tracking results to assist in setting the inter-lens distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the inter-lens distance is not set appropriately, then the head-mounted display can be used, but the display appears blurred to the user
Solution Approach 1:
The system provides real-time visual feedback by displaying the user's pupil position on the adjustment screen and showing alignment indicators that move according to the detected pupil-lens alignment. This feedback mechanism guides the user to adjust the inter-lens distance until the pupil aligns with the lens center, ensuring clear display while simplifying the adjustment process
Solution Approach 2:
The system uses the user's own eye tracking data to generate the adjustment screen content, where the pupil image is automatically positioned and scaled based on detected eye parameters. The alignment indicators are dynamically generated from the detected pupil position, allowing the system to self-adjust the display based on user-specific measurements
2Ease of operation
If an adjustment screen with eye tracking is implemented, then inter-lens distance setting is assisted, but device complexity increases
Solution Approach 1:
The adjustment screen serves multiple functions: it displays the pupil position, shows alignment indicators, provides visual guidance for adjustment, and records the final inter-lens distance setting. By consolidating these functions into a single interface, the system improves ease of operation while managing device complexity through functional integration
Solution Approach 2:
The adjustment screen acts as an intermediary between the eye tracking sensor and the lens adjustment mechanism. It translates complex eye tracking data into simple visual indicators that guide the user, and transmits the final alignment information to control the inter-lens distance setting, thereby simplifying the overall system complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates accurate adjustment of the inter-lens distance, improving display clarity and user experience in head-mounted displays.
Implementation Method 1
the distance between the lens for a left eye and the lens for a right eye (hereinafter, also referred to as an 'inter-lens distance') which are provided in a head-mounted display
Implementation Method 2
a pupil image that indicates a pupil of the user in reference to an eye tracking result

AI summary
An image generation apparatus generates an adjustment screen 300 that is for allowing a user who is wearing a head-mounted display to adjust an inter-lens distance for the head-mounted display, and causes the head-mounted display to display the adjustment screen 300. In the adjustment screen 300, disposed is a lens image (for example, a left lens image 304a and a right lens image 304b) that indicates a lens in the head-mounted display and also disposed is a pupil image (for example, the left eye image 306a and the right eye image 306b) that indicates a pupil of the user in reference to an eye tracking result.
