Mobile Terminal Emotion Service via Video Shake Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication terminals lack the ability to effectively convey user emotions beyond image transmission during video calls, failing to provide more efficient and lifelike communication services as requested by users.
Innovation Solution
A method and apparatus for providing an emotion expression service in mobile communication terminals, which involves recognizing shaking or facial expressions during video calls and generating corresponding vibrations, sound effects, or screen effects, and transmitting event request information to the other terminal to synchronize emotion expressions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only image transmission is used during video calls, then the communication service is simple and easy to implement, but the user experience lacks emotion expression and lifelikeness
Solution Approach 1:
The patent combines multiple emotion expression methods (vibration, sound effect, screen effect) into a unified emotion expression service that works during video calls. The control unit integrates image recognition results with these different output modalities to provide comprehensive emotion expression without requiring separate systems for each function.
Solution Approach 2:
The mobile communication terminal is designed to perform multiple functions using the same core components. The control unit uses the existing camera and image processing capabilities not only for video call functionality but also for recognizing shaking images and triggering emotion expressions through vibration, sound, or screen effects, making the system multi-functional without adding dedicated hardware for each function.
2Ease of operation
If shaking recognition and multiple emotion expression methods are added, then user interaction and lifelikeness are improved, but the device complexity increases
Solution Approach 1:
The system automatically recognizes shaking images captured during video calls and autonomously determines the appropriate emotion expression response. The control unit processes the image data, identifies shaking patterns, and triggers the corresponding vibration, sound effect, or screen effect without requiring manual user input or complex external processing, making the system self-sufficient in providing emotion expression services.
3Reliability
If real-time shaking recognition is implemented, then emotion synchronization between terminals is achieved, but the processing time and computational load increase
Solution Approach 1:
The system continuously captures images during video calls and maintains a ready state for shaking recognition. By pre-positioning the camera to capture shaking images and having the control unit continuously monitor incoming image data, the system is prepared to immediately recognize and respond to shaking motions as they occur, minimizing processing delays while maintaining accurate real-time emotion synchronization.

AI summary
A method and an apparatus for providing an emotion expression service in a mobile communication terminal are provided. The method includes performing a video call with another terminal, recognizing, by the mobile communication terminal, a shaking of the other terminal using images received from the other terminal, and generating a vibration of the mobile communication terminal corresponding to the recognized shaking of the other terminal.
