Interactive Video Display Region Adjustment via User Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive video display systems fail to provide a realistic browsing experience as they only adjust the visible region based on panning changes, ignoring posture changes, leading to inconsistent image changes perceived by the user.
Innovation Solution
The system includes a client with a detection device that acquires posture information, such as viewing angle and location, to adjust the visible region dynamically, using formulas to calculate region size changes and displacements based on user posture, ensuring the visible region aligns with real-world movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the visible region is adjusted only according to panning changes of user location, then the system complexity is reduced, but the browsing experience realism deteriorates
Solution Approach 1:
The patent applies parameter changes by transitioning from adjusting only the visible region based on panning to adjusting it based on multiple posture parameters including pitch, roll, and yaw angles. This allows the system to account for comprehensive user head movements, improving the realism of the browsing experience while maintaining manageable system complexity through systematic parameter processing.
2Reliability
If the visible region is adjusted based on comprehensive posture information, then the browsing experience realism is improved, but the device complexity increases
Solution Approach 1:
The patent implements universality by using a single detection device to acquire multiple types of posture information simultaneously (pitch, roll, yaw angles). This multi-functional approach allows the system to process comprehensive user movement data through one integrated device rather than requiring separate sensors for each parameter, thereby improving realism without proportionally increasing device complexity.
3Reliability
If multiple posture parameters are detected and processed, then the image change consistency with real situation is improved, but the measurement precision requirements increase
Solution Approach 1:
The patent employs feedback mechanisms by continuously detecting user posture parameters and dynamically adjusting the visible region in real-time based on the detected pitch, roll, and yaw angles. This closed-loop system ensures that the video display consistently reflects actual user head movements, improving image change consistency while the continuous feedback nature of the system helps maintain acceptable precision requirements through real-time adaptation.

AI summary
Embodiments of the present invention provide a method, a device, and a system for interactive video display, relate to the field of multimedia technologies, and can resolve a problem in the prior art that browsing experience of a user is not real because a visible region is simply changed only according to a panning change of a location of the user. A specific solution is: acquiring posture information of a user, where the posture information includes viewing angle information of the user and location information of the user; and adjusting, according to the posture information, an unadjusted visible region, in a video, for being displayed on a client, so as to obtain an adjusted visible region currently for being displayed on the client. The embodiments of the present invention are used for performing interactive video display.
