Animated Message Generation Preserving Handwriting Sequence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Multimedia Message Service (MMS) systems cannot effectively convey handwritten information as animated messages, failing to preserve the sequence and emotional state of the sender's input, as they convert handwritten data into static images, losing the input sequence and emotional context.
Innovation Solution
A method and apparatus for generating and playing animated messages by capturing handwritten input on a touch screen or extracting objects from images, using playback information to display objects in a specific order, allowing for dynamic animation and emotional expression, including a controller to generate and transmit animation messages with separate encoding regions for input and playback information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If handwritten information is converted into a single still image file using a separate application, then the message can be sent via MMS, but the input sequence and emotional state information of the sender is lost
Solution Approach 1:
The message is segmented into multiple frame data representing different time points of handwritten input, with each frame containing image data and associated metadata (input coordinates, input times). This segmentation preserves the sequential information while enabling animated playback without requiring complex external applications.
Solution Approach 2:
The patent combines the handwritten image data, input sequence information, and playback control data into a single integrated message structure that can be transmitted through standard MMS. This merging eliminates the need for separate applications while preserving all essential information.
2Loss of information
If handwritten information is converted into a single still image, then the message size is small and easy to transmit, but the emotional state and input sequence cannot be expressed
Solution Approach 1:
The patent extracts only the essential metadata (input coordinates and input times) from the complete handwritten input process, separating this sequence information from the full-resolution image data. This extraction preserves emotional state information while minimizing additional data size.
Solution Approach 2:
The patent uses lightweight frame data structures that copy only the necessary information (timestamps, coordinates, and compressed image references) rather than storing complete high-resolution images for each frame, thereby preserving temporal information while controlling message size.
3Reliability
If multiple frames of handwritten input are stored and transmitted, then the input sequence can be preserved, but the message complexity and transmission data increase
Solution Approach 1:
The patent implements dynamic frame sampling where the number and resolution of transmitted frames are adjusted based on the duration and complexity of the handwritten input. This allows the system to preserve input sequence reliability while adapting the data quantity to minimize transmission overhead.
Solution Approach 2:
The patent changes parameters such as frame resolution, frame rate, and compression level based on the characteristics of the handwritten input. This allows the system to maintain reliable sequence preservation while optimizing transmission data through parameter adaptation.

AI summary
A method and an electronic device are provided for transmitting a message from an electronic device to another electronic device. Handwritten input comprising one or more input objects is received. Playback information of the one or more input objects is generated using input coordinates of the one or more input objects or input times of the one or more input objects. An animation message including a first region in which one or more images are displayed, and a second region in which the one or more input objects are displayed, is generated according to the playback information. The animation message is transmitted to the another electronic device.
