Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for generating and sending emojis and virtual avatars are cumbersome and inefficient, requiring complex user interfaces and multiple inputs, wasting user time and device energy, particularly in battery-operated devices.
Innovation Solution
An electronic device with a camera and display provides a virtual avatar generation interface that reacts to facial expressions, allowing for the generation of static or animated avatars based on user inputs, reducing the need for complex interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing techniques are used for generating and sending emojis and virtual avatars, then the function of sending multimedia content is achieved, but the user interface becomes complex and time-consuming, requiring multiple key presses or keystrokes
Solution Approach 1:
The system automatically captures facial expressions via camera and generates corresponding emojis without requiring users to manually select from menus or press multiple keys. The emoji generation happens autonomously based on detected facial movements, making the system serve itself rather than requiring extensive user input.
Solution Approach 2:
The patent replaces the mechanical interaction of multiple key presses and manual menu navigation with an automated optical system. The camera detects facial expressions and the system automatically generates and sends emojis, substituting physical mechanical input operations with automated vision-based recognition and generation.
2Loss of energy
If existing techniques are used for generating and sending emojis and virtual avatars, then the function of sending multimedia content is achieved, but device energy is wasted, particularly in battery-operated devices
Solution Approach 1:
The camera and processing system operate continuously during the interaction, capturing facial expressions in real-time without requiring the user to stop and manually input data. This continuous operation eliminates the start-stop pattern of manual interaction, maintaining productive action throughout the emoji generation process while optimizing energy usage through efficient real-time processing.
Solution Approach 2:
The system autonomously generates and sends emojis without requiring users to spend time navigating interfaces or making selections. This self-service capability eliminates wasted time that would otherwise be spent on non-productive interface interactions, directly improving productivity while the system manages its own energy consumption efficiently.
3Ease of operation
If existing techniques are used for generating and sending emojis and virtual avatars, then the function of sending multimedia content is achieved, but user cognitive burden increases due to complex interactions
Solution Approach 1:
The system performs all complex operations autonomously - capturing facial expressions, analyzing them, generating appropriate emojis, and sending them without user intervention. This self-service approach eliminates the need for users to understand or navigate complex interface logic, reducing cognitive burden to nearly zero while the device handles all complexity internally.
Solution Approach 2:
The patent extracts the complex processing logic from the user interaction domain and places it entirely within the system. The user is presented with a simple camera-facing interface while all complex emoji generation and selection logic is extracted and handled automatically by the system, separating user simplicity from system complexity.

AI summary
The present disclosure generally relates to generating and modifying virtual avatars. An electronic device having a camera and a display apparatus displays a virtual avatar that changes appearance in response to changes in a face in a field of view of the camera. In response to detecting changes in one or more physical features of the face in the field of view of the camera, the electronic device modifies one or more features of the virtual avatar.
