Dynamic Camera Position Switching for Immersive 3D Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Viewers are limited in choosing their preferred perspective during events, as the content selection is controlled by broadcasters rather than the viewers themselves, lacking personal control over the viewing experience.
Innovation Solution
Implementing a system that allows users to select from multiple camera positions while viewing an event, using stereoscopic image data and user input to switch between camera perspectives, providing a 3D playback experience that mimics changing seats in the venue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the broadcaster controls the content feed selection, then the content presentation is standardized and easy to manage, but the viewer loses the ability to choose their preferred perspective
Solution Approach 1:
The system dynamically switches between different camera position feeds based on viewer selection. The playback device receives multiple content feeds from different camera positions and allows the viewer to select which perspective to view, making the system adaptable rather than fixed. This resolves the contradiction by maintaining ease of operation through automated feed switching while enabling viewer adaptability through selection capability.
Solution Approach 2:
The system prepares multiple camera position content feeds in advance and makes them available for selection before the viewer needs to switch perspectives. The playback device pre-receives and buffers content from multiple camera positions, so when a viewer selects a different perspective, the switch can occur immediately without delay. This resolves the contradiction by having content ready beforehand, maintaining operational smoothness while enabling viewer choice.
2Adaptability or versatility
If multiple camera positions are captured and made available, then the viewer has more perspective options, but the system complexity increases
Solution Approach 1:
The content delivery system segments the video content into separate feeds based on camera positions. Each camera position's content is delivered as an independent content feed to the playback device. This segmentation allows the system to manage multiple camera perspectives systematically, with each feed being independently controllable and selectable, thereby reducing overall system complexity while maintaining multiple options.
Solution Approach 2:
The playback device is designed with multi-functionality to handle multiple camera position feeds simultaneously. It can receive, process, and switch between different camera perspectives using a single device, rather than requiring separate systems for each camera position. This universal capability reduces system complexity by consolidating multiple functions into one device while still providing diverse perspective options to the viewer.
3Adaptability or versatility
If the system switches camera positions based on viewer input, then the viewing experience becomes personalized, but the operation becomes more complex
Solution Approach 1:
The system allows the viewer to self-select their preferred camera position from available options. The playback device presents the list of available camera positions to the viewer, and the viewer independently makes the selection without requiring complex controller operations or intermediary steps. This self-service approach personalizes the viewing experience while maintaining ease of operation through simple, intuitive viewer control.
Solution Approach 2:
The system provides feedback to the viewer by displaying the currently selected camera position and the available alternative positions. This feedback mechanism helps the viewer understand their current viewing perspective and makes informed decisions about switching to different camera positions. The feedback simplifies operation by making the system's state transparent, reducing the cognitive load required to control the viewing experience.

AI summary
Methods and apparatus for allowing a user to switch viewing positions and/or perspective while viewing an environment, e.g., as part of a 3D playback/viewing experience, are described. In various embodiments images of the environment are captured using cameras placed at multiple camera positions. During viewing a user can select which camera position he/she would like to experience the environment from. While experiencing the environment from the perspective of a first camera position the user may switch from the first to a second camera position by looking at the second position. A visual indication is provided to the user to indicate that the user can select the other camera position as his/her viewing position. If a user input indicates a desired viewing position change, a switch to the alternate viewing position is made and the user is presented with images captured from the perspective of the user selected alternative viewing position.
