Head-Mounted Display Eye Tracking Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted electronic devices often fail to ensure optimal display alignment with the user's eyes, leading to suboptimal viewing experiences due to improper fitting, which affects the quality of 3D content and user comfort.
Innovation Solution
An electronic device with a sensor system that captures images of the user's eyes to determine the wearing state and adjust the display screens accordingly, ensuring proper alignment based on inter-pupillary distance and eye location, and provides a guide screen to assist in correct device fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a head-mounted electronic device is adjusted to fit the user's head using a strap, then the device can be secured on the user's head, but the display screen may not be aligned at a suitable location for the user's eyes
Solution Approach 1:
The patent employs a sensor to capture images of the user's eyes and provides real-time feedback about eye position and device alignment. The processor analyzes the captured images to determine the relative position between the display screen and the user's eyes, then adjusts the display parameters or provides guidance to the user for proper alignment, creating a closed-loop feedback system that resolves the alignment inaccuracy
Solution Approach 2:
The patent replaces manual mechanical adjustment of the display position with an automated optical detection system. Instead of relying on physical trial-and-error adjustment, the system uses sensors to detect eye position and automatically determines the appropriate display alignment, substituting mechanical adjustment with optical measurement and computational analysis
2Ease of operation
If the display screen is positioned for optimal viewing, then the user experience is improved, but the device may not fit securely on different user heads
Solution Approach 1:
The patent makes the head-mounted device universally adaptable to different users by implementing a sensor-based eye position detection system that automatically adjusts to each user's unique anatomy. The device captures images of the user's eyes, processes the position information, and configures the display accordingly, allowing the same device to provide optimal viewing experience for multiple users with different head sizes and eye positions without requiring physical customization for each user
3Ease of manufacture
If the device structure is simplified for easy manufacturing, then production cost is reduced, but the ability to detect and measure eye position accurately is compromised
Solution Approach 1:
The patent introduces an intermediary sensor system that bridges the gap between the simple device structure and the complex measurement requirement. The sensor acts as a mediator that captures optical information from the user's eyes and converts it into usable position data, enabling accurate eye position detection without requiring complex mechanical or structural modifications to the device itself

AI summary
An electronic device is provided. The electronic device mountable on a head of a user includes a display, a sensor configured to capture an image, a processor electrically connected with the display and the sensor, and a memory electrically connected with the processor, wherein the memory includes instructions, which, when executed, cause the processor to provide a guide screen that guides the user to gaze at a front of a display, to capture an image, in which at least a portion of an eye of the user is included, using the sensor, and to determine a wearing state of the electronic device based on at least one of a location of the eye or a location of a pupil of the user displayed in the captured image.
