Panoramic TV Display Control Using Mobile Viewpoint Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital televisions lack the capability to effectively display panoramic images with a stereoscopic effect and limited viewing angles, hindering the immersive experience provided by panoramic videos.
Innovation Solution
A method and apparatus that adjust the viewing angle and viewpoint of panoramic images on smart televisions using a mobile device, leveraging Wi-Fi and Bluetooth indoor positioning, gyroscope data, and a coordinate system mapping to dynamically adjust the panoramic image based on the user's location and posture changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If panoramic images are displayed on smart televisions, then the stereoscopic effect and sense of reality are improved, but the viewing angle range is limited and the immersive experience is reduced
Solution Approach 1:
The patent implements dynamic adjustment of panoramic image display by tracking the mobile terminal's orientation and position in real-time. The system continuously updates the viewing angle and displayed content based on the user's movement, transforming a static display into a dynamic immersive experience that adapts to user actions while maintaining the stereoscopic effect on the fixed television screen.
Solution Approach 2:
The patent introduces a mobile terminal as an intermediary device between the user and the panoramic content. The mobile terminal captures orientation and position data, which then controls the display on the smart television. This intermediary enables the user to navigate the panoramic environment naturally through device movement, effectively extending the viewing angle range beyond the television's physical constraints.
2Adaptability or versatility
If the viewing angle of panoramic images is increased to improve immersion, then the sense of reality is enhanced, but the control complexity increases
Solution Approach 1:
The system employs self-service control by automatically tracking the mobile terminal's orientation and position without requiring manual input. The panoramic image adjusts itself based on the device's natural movement in three-dimensional space, eliminating the need for complex control interfaces or user configuration while achieving immersive viewing angle adjustment.
Solution Approach 2:
The patent implements feedback control by continuously monitoring the mobile terminal's orientation and position data and using this information to adjust the panoramic image display in real-time. This closed-loop system automatically adapts the viewing angle based on user movement, simplifying control while maintaining high adaptability and immersion.
3Device complexity
If traditional video playback is used on smart televisions, then the device simplicity is maintained, but the viewing angle is limited and stereoscopic effect is lost
Solution Approach 1:
The patent transitions from traditional two-dimensional video playback to three-dimensional panoramic imaging. By utilizing the mobile terminal's three-dimensional movement data (orientation and position), the system creates an immersive panoramic viewing experience on the television, adding spatial depth and stereoscopic effects while maintaining relatively simple device architecture.
