Mobile Terminal Video Call Context Sharing via Object Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals face limitations in enhancing the efficiency of video calls by only transmitting user images and speech, lacking the ability to effectively convey additional information such as surrounding environments and object details during communication.
Innovation Solution
A mobile terminal with a camera module, wireless communication unit, and control unit that captures and transmits surrounding images and object information, utilizing augmented reality to enhance video calls by overlaying relevant data on the user interface, allowing users to share contextual information during video conferencing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only user images and speech are transmitted during video calls, then the communication bandwidth requirement is reduced, but the information completeness and contextual understanding deteriorate
Solution Approach 1:
The patent extracts and transmits only the essential contextual information (surrounding environment images and identified object information) separately from the main video call data stream. This allows selective transmission of additional information without requiring complete retransmission of all video data, thereby improving information completeness while controlling transmission complexity.
Solution Approach 2:
The patent introduces an intermediary object recognition system that processes surrounding environment images and extracts meaningful object information. This intermediary layer transforms raw visual data into structured, transmittable information, reducing the complexity of direct full-image transmission while preserving essential contextual details.
2Adaptability or versatility
If surrounding environment images and object information are transmitted, then the contextual information sharing is improved, but the data transmission volume and processing load increase
Solution Approach 1:
The patent segments the transmitted data into distinct components: user video feed, surrounding environment images, and extracted object information. This segmentation allows selective transmission based on communication needs, improving versatility while enabling efficient bandwidth management by transmitting only relevant segments.
Solution Approach 2:
The patent implements partial action by transmitting only the most relevant object information from the surrounding environment rather than complete environmental data. The system selectively identifies and transmits key objects that enhance communication context, avoiding excessive data transmission while maintaining enhanced functionality.
3Loss of information
If object recognition and information extraction are performed, then the usefulness of transmitted data is improved, but the processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary object recognition and information extraction on surrounding environment images before transmission. By pre-processing the visual data to identify and extract meaningful object information in advance, the system reduces real-time processing requirements during active communication, thereby improving information quality while minimizing processing time delays.

AI summary
A mobile terminal may be provided that includes a camera module, a wireless communication unit to perform a video call with another party, a display to display a video call relevant image, a location information module to obtain location information of the mobile terminal, and a controller to obtain object information of an object within an image captured by the camera module based on the obtained location information of the mobile terminal. The controller may control the obtained object information to be transmitted to a terminal of the other party.
