Camera-Tracked 3D Object Position and Depth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D display technologies, particularly glasses-free light field displays, struggle to effectively adjust the position and depth of objects in a 3D virtual space based on user movement, leading to suboptimal three-dimensional experiences.
Innovation Solution
An electronic apparatus equipped with a camera, memory, and processor is configured to identify user head or eye movement information, map this to a 3D virtual space, and adjust the display position and depth of objects within the 3D image accordingly, using techniques such as disparity analysis and scaling to enhance the 3D experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If glasses-free light field display is used to provide 3D effect on a single screen, then the three-dimensional effect is achieved without auxiliary devices, but the ability to effectively adjust object position and depth based on user movement is insufficient
Solution Approach 1:
The patent implements dynamic adjustment of object position and depth in the 3D virtual space based on real-time user head or eye movement detection. The system continuously updates object parameters according to user movement information, transforming a static display into a dynamic interactive experience that adapts to user behavior without requiring manual control inputs.
Solution Approach 2:
The system establishes a feedback loop where user movement is detected by the camera, processed to generate movement information, and used to adjust the display output. This closed-loop mechanism ensures that the 3D display responds automatically to user actions, improving both adaptability and ease of operation by eliminating the need for separate control devices.
2Reliability
If user movement information is captured and processed to adjust 3D object positions, then the three-dimensional experience is enhanced, but the system complexity increases
Solution Approach 1:
The camera system serves multiple functions: capturing user movement information, tracking head or eye position, and providing data for 3D object adjustment. By making the camera multi-functional, the patent avoids adding separate sensors or devices, thereby enhancing 3D experience quality without proportionally increasing system complexity.
Solution Approach 2:
The processor acts as an intermediary that bridges the camera and display components. It captures movement data from the camera, processes this information to determine appropriate object adjustments, and controls the display output. This intermediary approach simplifies the overall system architecture by using a single processing unit to coordinate multiple functions rather than requiring direct complex interconnections between components.
