Avatar View Display Masking for Accurate Gaze Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual spaces, the line of sight of a user operating an avatar is often unclear, as existing systems do not accurately determine what the user is looking at beyond the direct line of sight, leading to ambiguity in user interaction.
Innovation Solution
A virtual space providing device that detects the direction of an avatar, outputs an image with a changed display mode outside a predetermined range, and estimates the user's line of sight based on this image, using techniques such as blurring or masking to focus attention on specific areas.

Engineering Contradiction Analysis
1Measurement precision
If a line is drawn in the line-of-sight direction of an avatar and an object that collides first with the line is specified as an object pointed to by the user, then the system can determine an object pointed to by the user, but the user does not necessarily look at the object ahead of the line of sight of the avatar, leading to inaccurate line of sight estimation
Solution Approach 1:
The patent applies local quality by changing the display mode of different regions in the output image. Specifically, the display mode is changed for regions outside a predetermined range (such as blurring or masking), while the center region maintains normal display mode. This creates localized visual differences that guide the user's attention and enable more accurate line of sight estimation based on where the user focuses their attention rather than just the avatar's orientation.
2Measurement precision
If the display mode outside a predetermined range is changed to focus user attention, then line of sight estimation accuracy improves, but the user may not notice the change and the system becomes more complex
Solution Approach 1:
The system uses feedback by continuously monitoring the user's line of sight estimation results and adjusting the display mode changes accordingly. The output control unit changes the display mode based on the estimated line of sight, creating a feedback loop that refines the estimation accuracy over time while adapting to user behavior patterns.
