Headset Media Preview via Viewpoint Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in determining how videos would look when rendered as three-dimensional or immersive content while browsing, as existing technologies lack effective methods for presenting media content previews in virtual reality environments.
Innovation Solution
A method and system for presenting media content previews on a user device associated with a headset display, where thumbnail images are displayed, and upon directing the viewpoint towards a selected thumbnail, a content preview is shown, which can change views based on user orientation, resuming thumbnail display when the viewpoint is no longer directed at the preview, and optionally presenting as stereoscopic content with associated audio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional video browsing interfaces are used on headset displays, then device compatibility is maintained, but users cannot determine how videos would look when rendered as three-dimensional or immersive content
Solution Approach 1:
The patent transitions from traditional 2D video previews to 360-degree spherical video previews that leverage the headset display's capabilities. The spherical video renderer projects video frames onto a spherical surface, allowing users to view content from multiple angles and understand the immersive rendering appearance, thus resolving the information loss about how videos would look in 3D/immersive format.
Solution Approach 2:
The patent introduces a spherical video renderer as an intermediary component between the video content and the headset display. This renderer processes standard video content and transforms it into a spherical projection format that can be displayed on the headset, serving as a mediator that enables immersive preview without requiring the original content to be in immersive format.
2Ease of operation
If spherical video rendering is implemented for content previews, then immersive viewing experience is provided, but additional processing and rendering complexity is introduced
Solution Approach 1:
The spherical video renderer is designed to handle both traditional video content and immersive content through a unified interface. It can process standard video files and transform them into spherical projections, while also being capable of displaying native 360-degree content, thus providing multi-functionality that reduces the need for separate processing pipelines and reduces overall system complexity.
Solution Approach 2:
The patent creates a simplified spherical projection copy of the video content for preview purposes. Instead of requiring full immersive content processing, it generates a spherical representation that captures the essential immersive characteristics, allowing users to preview the experience without the computational overhead of processing complete immersive content.
3Adaptability or versatility
If spherical video previews are displayed on headset display, then immersive content preview is enabled, but display area for thumbnail images is reduced
Solution Approach 1:
The user interface implements dynamic switching between thumbnail view and spherical video preview based on user interaction. When a user selects a thumbnail, the interface transitions to display the spherical video preview, and when the preview is dismissed, it returns to the thumbnail grid. This dynamic behavior allows the display area to be flexibly allocated between thumbnails and previews, resolving the area conflict.
Solution Approach 2:
The spherical video preview is integrated within the existing thumbnail-based browsing interface. The preview can be displayed in a nested manner within the same display space, allowing users to navigate between thumbnail selection and immersive preview without completely leaving the browsing context, thus optimizing the use of available display area.

AI summary
Methods, systems, and media for presenting media content previews are provided. In some embodiments, the method comprises: causing a plurality of thumbnail images to be presented on a page presented on a user device, wherein each thumbnail image represents a media content item available for presentation on the user device, and wherein the user device is associated with a headset display; determining that a viewpoint of the headset display is directed to one of the thumbnail images of the plurality of thumbnail images; in response to determining that the viewpoint of the headset display is directed to the one of the thumbnail images, causing a first view of a content preview corresponding to the one of the thumbnail images to be presented on the headset display, wherein the content preview includes a second view that is different than and does not include the first view; detecting that the viewpoint of the headset display has changed in a direction toward the second view of the content preview; in response to detecting that the viewpoint of the headset display has changed in the direction toward the second view of the content preview, causing the second view of the content preview to be presented on the headset display; determining that the viewpoint of the headset display is no longer directed to the content preview; and in response to determining that the viewpoint of the headset display is no longer directed to the content preview, causing presentation of the second view of the content preview to be inhibited and causing presentation of the plurality of thumbnail images to resume on the headset display.
