Head Orientation Tracking for Seamless Video Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computer-generated reality environments, transitioning between 360-degree video clips can result in the user not seeing the relevant spatial portions, as the display often defaults to a fixed location rather than adjusting to the user's current head orientation, leading to a disjointed experience.
Innovation Solution
A method and device that utilize head orientation tracking to seamlessly transition between video clips by displaying the relevant spatial portion of each clip based on the user's current head orientation, ensuring a continuous and immersive experience by aligning the video content with the user's viewpoint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed location is used for displaying video content during transitions, then the display system remains simple and stable, but the user experience becomes disjointed and immersion is reduced
Solution Approach 1:
The display system dynamically adjusts the spatial portion of video clips based on tracked head orientation. During transitions between video clips, the system continuously updates which spatial region is displayed, transforming from a static fixed-location display to a dynamic orientation-based display that maintains user immersion and experience continuity.
2Reliability
If the display adjusts to user head orientation during transitions, then immersion and continuity are enhanced, but the device complexity and processing requirements increase
Solution Approach 1:
The system implements a feedback loop where head orientation is continuously tracked and used to control the display of spatial video portions. During transitions, the tracked head orientation provides real-time feedback that determines which spatial region should be displayed, ensuring the video content remains aligned with user viewpoint and maintaining immersion without requiring complex manual intervention.
3Ease of operation
If head orientation tracking is used to control video display, then the user experience becomes immersive and continuous, but the measurement and detection requirements become more difficult
Solution Approach 1:
The system uses the user's own head orientation to automatically control the video display during transitions. The head tracking mechanism captures the user's natural head movements and orientations, and this self-generated data directly controls which spatial portions of the video are displayed, creating an immersive experience where the system adapts to the user's natural behavior without requiring external control inputs.

AI summary
In one implementation, a method of displaying multiple video clips includes, while a head orientation of a user is a first head orientation represented by a first set of head orientation values, displaying, on the display, a first spatial portion of a first video clip. The method includes, in response to detecting a change in the head orientation to a second head orientation represented by a second set of head orientation values, displaying, on the display, a second spatial portion of the first video clip, wherein the second spatial portion is selected for display based on the second set of head orientation values. The method includes, while the head orientation is the second head orientation, displaying, on the display, a first spatial portion of a second video clip, wherein the first spatial portion of the second video clip is selected for display based on a predetermined head orientation value.
