Gaze-Controlled Dynamic Videotelephony Camera Focus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video telephony systems lack the ability for users to dynamically control the focus of the camera, limiting the viewing angle and object of interest during video conferences, making it difficult for participants to adjust the visual scene based on their preferences.
Innovation Solution
A dynamic videotelephony system that includes a camera group and a gaze detection device group, which captures and transmits video signals and tracks the principal location of pupils to control the camera focus, allowing users to select and center the visual scene on the object of interest based on their gaze.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera is fixed, then the device structure is simple, but the viewing angle and focus control are limited
Solution Approach 1:
The system automatically adjusts camera focus and viewing angle based on detected user gaze direction, eliminating the need for manual control while providing dynamic focus adjustment capability
Solution Approach 2:
The patent replaces manual mechanical camera adjustment with an automated optical system that uses gaze detection (optical field) to control camera focusing and orientation, substituting mechanical user interaction with an optical-based control mechanism
2Adaptability or versatility
If the camera viewing angle is fixed, then the device structure is simple, but the visual scene coverage is limited
Solution Approach 1:
The camera system transitions from a fixed static configuration to a dynamic adjustable system that automatically changes viewing angle and focus based on real-time gaze detection, enabling adaptability without requiring complex manual controls
Solution Approach 2:
The system autonomously adjusts its own camera parameters (viewing angle, focus) based on detected user attention, providing adaptive visual scene coverage without requiring external control input
3Extent of automation
If manual camera control is provided, then user interaction is possible, but the operation complexity increases
Solution Approach 1:
The camera control system operates autonomously by detecting user gaze and automatically adjusting focus and viewing angle, achieving high automation while maintaining ease of operation through implicit control
Solution Approach 2:
The system implements a feedback loop where gaze detection continuously monitors user attention and dynamically adjusts camera parameters in real-time, creating an automated control system that responds to user intent without manual input

AI summary
Aspects of present disclosure relates to a dynamic videotelephony system. In certain embodiments, dynamic videotelephony system includes a first dynamic videotelephony device for a first user group, and a second dynamic videotelephony device for a second user group, and a network connecting these two dynamic videotelephony devices for a dynamic video conference between the two user groups. Each of the dynamic videotelephony devices has a gaze detection device group to detect a corresponding principal location of pupils of a corresponding user group, and sends control instructions to the opposite dynamic videotelephony device to control dynamic video capturing such that the captured dynamic video is focused and centered at an object corresponding to the corresponding principal location of pupils of the corresponding user group on the corresponding dynamic video display device, and the captured dynamic video is transmitted from the opposite dynamic videotelephony device to corresponding dynamic videotelephony device for display.
