Multi-Dimensional Media ROI Detection on 2D Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limitation of two-dimensional screens in rendering multi-dimensional media, such as 360-degree videos, results in an unpleasant user experience due to restricted viewing areas and the need for manual navigation to identify regions of interest.
Innovation Solution
A mechanism is provided for an electronic device to receive and display multi-dimensional media, detect regions of interest (ROI) based on parameters like visual and audio attention models, and automatically display indications for secondary view ports containing these ROIs, enhancing user navigation and reducing manual effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multi-dimensional media is rendered on a 2D screen, then the viewing area is limited, but the user experience deteriorates
Solution Approach 1:
The patent segments the multi-dimensional media into multiple view ports, each displaying a different region of interest. This allows the system to present multiple segments of the 360-degree video simultaneously on the 2D screen, effectively expanding the usable viewing area while maintaining good user experience through automatic ROI detection and display.
2Ease of operation
If manual swiping/scrolling is required to identify interested segments, then navigation control is improved, but user effort increases
Solution Approach 1:
The system performs self-service by automatically detecting regions of interest in the multi-dimensional media and displaying them as view ports without requiring manual user intervention. The automatic ROI detection algorithm identifies interesting segments and presents them to the user, eliminating the need for manual swiping or scrolling while maintaining excellent navigation control.
Solution Approach 2:
The system performs preliminary action by pre-detecting and marking regions of interest before user viewing. The ROI detection is performed in advance, and the identified segments are prepared as view ports ready for display, so users don't need to manually search through the content.
3Extent of automation
If automatic ROI detection is implemented, then user navigation effort is reduced, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary component - the ROI detection module - that acts as a mediator between the multi-dimensional media and the display system. This module automatically identifies regions of interest using various parameters (visual attention models, audio attention models, etc.) and translates them into displayable view ports, thereby achieving high automation while managing system complexity through modular design.

AI summary
An electronic device and a method for automatically displaying an indication in a multi-dimensional media in the electronic device are provided. The method includes receiving the multi-dimensional media at the electronic device, displaying a first view port of the multi-dimensional media on a screen of the electronic device, detecting at least one region of interest (ROI) in the multi-dimensional media based on plurality of parameters, and displaying an indication indicating at least one second view port of the multi-dimensional media on the screen. The second view port includes at least one ROI.
