Extended Viewport via Mobile Display Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices are inadequate for shared viewing experiences of immersive videos due to limited screen sizes, which restricts the ability to clearly see details in shared settings, despite advancements in mobile bandwidth and video resolution.
Innovation Solution
A system that identifies and configures multiple mobile display devices to create an extended viewport, allowing access to hidden or extra media content by associating primary and adjacent display devices and presenting extended segments of video content through a mosaic configuration, using peer-to-peer communication and near-field technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple mobile display devices are associated to create an extended viewport, then the viewing area and access to media content is improved, but the device complexity and coordination requirements increase
Solution Approach 1:
The immersive video content is divided into multiple spatial segments, with each mobile display device presenting a specific segment (primary viewport or adjacent viewports). This segmentation allows the viewing area to be expanded across multiple devices while each device maintains a manageable level of complexity by handling only its assigned segment.
Solution Approach 2:
Multiple mobile display devices are merged into a coordinated presentation system where their individual displays combine to form an extended viewport. The devices are associated through proximity detection and communicate via peer-to-peer channels to collectively present the full immersive video content, achieving a larger viewing area while leveraging the existing capabilities of individual devices.
2Ease of operation
If immersive video content is transformed based on user's line of sight and field of view, then the viewing experience is improved, but the computational requirements and processing complexity increase
Solution Approach 1:
The computational task of transforming immersive video content is segmented across multiple mobile display devices. Each device performs the transformation independently on its assigned spatial segment based on its own line of sight and field of view parameters, reducing the processing complexity on any single device while maintaining an improved viewing experience through coordinated presentation.
Solution Approach 2:
Each mobile display device autonomously performs the video transformation required for its specific viewport segment without requiring centralized processing. The devices self-manage their own line of sight and field of view calculations, reducing overall system complexity while delivering an enhanced viewing experience.
3Device complexity
If a single mobile device is used for viewing, then the device simplicity is maintained, but the ability to clearly see details in shared settings deteriorates
Solution Approach 1:
Multiple simple mobile devices are merged into a coordinated presentation system that collectively provides enhanced detail visibility. Each device maintains its simplicity while the combination of multiple displays enables clear viewing of immersive video details in shared settings, resolving the contradiction between device simplicity and viewing quality.

AI summary
Aspects of the subject disclosure may include, for example, identifying a media content item having first and second portions adapted for presentation according to first and second viewports that facilitate access to an extended portion of the media content item otherwise inaccessible via the first viewport. First and second display devices are associated together, configuration parameters are determined, and a viewport configuration is identified for the first and second viewports according to the configuration parameters. The first and second portions of the media content items are received by the first and second display devices to facilitate first and second presentations of the first and second portions of the media content item. The first and second presentations, according to the viewport configuration, provide a collective display of the extended portion of the media content item. Other embodiments are disclosed.
