Operator Determination via Line of Sight in User Interface Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a method to effectively determine the operator performing operations through line of sight, which is essential for processing based on user line of sight in user interface systems.
Innovation Solution
An information processing apparatus and method that acquires a captured image of users, determines the operator by various criteria such as face region size, distance, or gestures, and conducts processes based on the determined operator's line of sight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If line-of-sight detection technology is used to enable user operation, then user interface capability is improved, but the ability to determine which user is the operator deteriorates
Solution Approach 1:
The system segments the determination of operator status into multiple independent criteria: face region size analysis, distance measurement from the apparatus, and gesture detection. Each criterion independently evaluates user characteristics, and their results are combined to determine the operator, thereby improving accuracy while maintaining versatility
Solution Approach 2:
The system introduces an intermediary determination unit that acts as a mediator between the line-of-sight detection technology and the operator identification. This unit integrates multiple detection results (face size, distance, gestures) to resolve ambiguity and accurately identify the operator, enabling both versatile UI operation and precise operator determination
2Adaptability or versatility
If multiple users are included in the captured image, then system inclusivity is improved, but operator identification reliability deteriorates
Solution Approach 1:
The system applies different evaluation criteria to different users in the captured image based on their local characteristics. Each user's face region size, distance from the apparatus, and performed gestures are individually analyzed, allowing the system to maintain high reliability in operator identification even when multiple users are present by evaluating each user's specific attributes
