Head-guide system for vision training alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vision training methods face challenges in maintaining proper alignment of a user's head and display, leading to misalignment of visual stimuli and reduced effectiveness, especially outside clinical settings and for users with cognitive disabilities.
Innovation Solution
A head-guide system comprising a head-support, display-support, and guide-support, pre-configured to fix the relative position of the head and display, with a CPU generating visual stimuli based on pre-configured settings to ensure accurate positioning and effective vision training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user fixes their gaze in a particular location during vision training, then the visual stimuli can be presented to the intended zones, but the user's head position becomes misaligned after being in an unsupported fixed position for a relatively long period of time
Solution Approach 1:
The head support device is pre-configured with the display device at specific relative positions and orientations before the vision training session begins. This preliminary setup ensures that the user's head is properly positioned relative to the display without requiring the user to maintain an unsupported fixed position during the training session, thereby preventing misalignment while maintaining precision.
2Measurement precision
If a user attempts to fix their head's position relative to a display, then alignment can be achieved, but identifying the proper position is difficult and requires substantial time
Solution Approach 1:
The head support and display support are pre-configured with predetermined relative positions and orientations before the vision training session. This eliminates the need for users to spend substantial time identifying and adjusting the proper position during setup, as the correct alignment is already established in advance.
Solution Approach 2:
The head support device acts as an intermediary between the user and the display device, providing a physical structure that automatically establishes the correct spatial relationship. This mediator eliminates the need for users to manually identify and adjust positioning, significantly reducing setup time while maintaining alignment precision.
3Ease of operation
If visual stimuli are presented without proper head positioning, then the training can proceed without setup complexity, but the effectiveness of the training is limited due to misalignment
Solution Approach 1:
The head support and display support are pre-configured with predetermined relative positions and orientations before the vision training session. This preliminary setup maintains operation simplicity by eliminating complex adjustment procedures while ensuring training effectiveness through proper alignment of visual stimuli with the user's visual field.

AI summary
A head-guide for diagnosing or training vision of a user and methods of user thereof are disclosed. The head-guide may include a head-support for orienting a head of the user, a display-support for orienting a display. The head-guide may also include a guide-support connected to the head-support and the display-support. The head-support and display-support may be pre-configured to fix the relative position of the head and the display and the display may present visual stimuli to diagnose or train the vision of the user.
