Video Conference Camera View Adjustment via Eye Gaze Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video conferencing devices cannot automatically focus on objects being discussed by a presenting user when they are not within the camera's view, requiring manual adjustments, which hinders remote participants' ability to see the object clearly.
Innovation Solution
A network video communication device and method that captures real-time images and processes user information, including eye gaze direction, to adjust the camera view of a second device to focus on the presenting user's line of sight, ensuring remote participants can see the discussed object clearly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera captures real-time video images of the presenting user's face, then the presenting user can be seen clearly by remote participants, but objects being discussed by the presenting user cannot be captured when they are not within the camera's view
Solution Approach 1:
The patent applies dynamics by making the camera view adjustable and adaptive. The camera can dynamically switch between capturing the presenting user's face and capturing objects being discussed, based on real-time feedback about what the presenting user is looking at or discussing. This resolves the contradiction by allowing the system to adapt its capture scope from fixed face-only to dynamic object-focused viewing.
Solution Approach 2:
The patent uses feedback mechanisms where the system detects what the presenting user is looking at (via eye tracking or other sensors) and automatically adjusts the camera view accordingly. This feedback loop enables the camera to automatically focus on objects of interest rather than remaining fixed on the user's face, solving the contradiction between face capture precision and object capture adaptability.
2Ease of operation
If the presenting user manually adjusts the camera view or object position to show objects, then objects can be seen on the video conference screen, but this requires manual intervention and time consumption
Solution Approach 1:
The patent implements self-service by enabling the camera system to automatically adjust its own view based on detecting what the presenting user is looking at or discussing. The system performs the adjustment function autonomously without requiring manual intervention from the presenting user, thereby resolving the contradiction between ease of operation and time loss.
Solution Approach 2:
The system performs preliminary detection of the presenting user's gaze direction or discussion topic before actually switching the camera view. This preliminary action allows the system to proactively adjust the camera position in advance, eliminating the need for manual adjustment and reducing time loss.
3Stability of the object's composition
If the camera maintains a fixed view on the presenting user's face, then the setup is simple and stable, but remote participants cannot see objects being discussed in detail
Solution Approach 1:
The patent transitions from a static, fixed camera view to a dynamic view that can adapt between the presenting user's face and discussed objects. This dynamic capability allows the system to maintain stability when needed (fixed view on user) while providing object detail information when required (switched view on object), resolving the contradiction between view stability and information completeness.
