Immersive Video Perspective Transition System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In immersive 360-degree video experiences, viewers adjusting the perspective away from the filmmaker's intended view can miss important aspects and require manual input to return, leading to a degraded user experience due to the lack of automatic and visually pleasing transitions back to the predetermined perspective.
Innovation Solution
Implementing a system that allows viewers to freely adjust the perspective within immersive video experiences while automatically returning to the filmmaker's defined path through a sequence of keyframes, using interpolation functions like spherical linear interpolation and quadratic easing, ensuring a seamless and visually appealing transition without further user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If viewers are given control to adjust the perspective freely, then viewer freedom and exploration capability are improved, but the risk of missing important aspects and requiring manual input to return increases
Solution Approach 1:
The system automatically returns the viewport to the filmmaker's defined path without requiring manual user input. The automated return mechanism monitors when the viewport has drifted from the intended path and autonomously initiates the transition back, allowing the system to serve itself rather than requiring continuous user intervention.
Solution Approach 2:
The system continuously monitors the viewport orientation and compares it against the filmmaker's defined path. When deviation is detected, the system provides feedback by automatically initiating a return transition, creating a closed-loop control system that maintains the intended viewing experience without user intervention.
2Ease of operation
If automatic return to filmmaker's perspective is implemented, then user experience is improved, but transition smoothness and visual appeal become critical requirements
Solution Approach 1:
The transition function dynamically adjusts the viewport orientation from the user-adjusted position back to the filmmaker's defined path. Rather than using a fixed, abrupt transition, the system employs dynamic interpolation that smoothly evolves the viewport orientation over time, creating a natural and visually pleasing return transition.
Solution Approach 2:
The patent employs spherical linear interpolation (slerp) for transitioning between orientations in 360-degree video. This curved interpolation method follows the spherical geometry of the immersive video space, creating smooth arc-shaped transitions that are visually pleasing and maintain spatial coherence, rather than using linear or angular interpolations that would create discontinuities.
3Area of stationary object
If multiple cameras are used to capture 360-degree video, then panoramic coverage is improved, but stitching complexity and processing requirements increase
Solution Approach 1:
The system merges multiple camera feeds into a single coherent 360-degree panoramic view through stitching. By combining the overlapping fields of view from multiple cameras and aligning them spatially, the system creates a unified immersive video experience that provides complete panoramic coverage while managing the complexity of coordinating multiple capture devices.

AI summary
An immersive video experience can include a path between a plurality of keyframes selected by the filmmaker. A viewer can be given control of the view in the immersive video experience to provide the viewer freedom to look around and explore the scene. To improve user experience, after the user adjusts the perspective of the immersive video to depart from a filmmaker's defined perspective, the perspective can be returned to resume the filmmaker's defined perspective to avoid the viewer missing important parts of the immersive video. Additionally, the user experience can be improved by having the return from the user-adjusted perspective to the filmmaker's defined perspective include a visually pleasing transition that does not require further user input.
