Handwriting Animation Message Synchronization via Temporal Frame Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Multimedia Message Service (MMS) does not effectively transmit handwriting content as animation, requiring conversion to still or moving images, which loses the sequential nature of handwriting and requires users to manually reorder images on the receiving end.
Innovation Solution
An apparatus and method that synchronizes handwriting animation messages with a background image, storing time and coordinate information to generate a final still image, which is then transmitted, allowing the receiving terminal to reconstruct and reproduce the animation on the original background image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If handwriting content is converted to still image or moving image file using separate program, then the handwriting content can be transmitted through MMS, but the sequential nature of handwriting is lost and animation effect is not achieved
Solution Approach 1:
The handwriting content is divided into multiple frames (first handwriting frame, second handwriting frame, etc.) that are transmitted separately. Each frame contains portion of the handwriting content at different stages, allowing the receiving terminal to reconstruct the sequential handwriting animation by displaying frames in order.
Solution Approach 2:
The system transforms static image transmission into dynamic animation transmission by capturing handwriting content as a sequence of frames with temporal information. The controller at the receiving terminal displays these frames sequentially to create the animation effect, making the transmitted content dynamic rather than static.
2Adaptability or versatility
If multiple still images or moving images are transmitted, then the handwriting content can be transmitted, but the user has to download and check each image to identify the creation order
Solution Approach 1:
The controller at the transmitting terminal automatically determines and transmits the correct order of handwriting frames based on the temporal information captured during handwriting input. The receiving terminal automatically displays frames in the correct sequence without requiring manual intervention, as the ordering information is pre-established in the transmitted data.
Solution Approach 2:
The system performs automatic frame ordering and animation reconstruction at the receiving terminal without requiring user intervention. The controller at the receiving terminal autonomously processes the transmitted frames, uses the temporal information to determine the correct sequence, and displays the handwriting animation automatically, eliminating the need for manual image checking and reordering.
3Adaptability or versatility
If handwriting animation messages are transmitted separately from background image, then the transmission is flexible, but the synchronization between handwriting animation and background image is lost
Solution Approach 1:
The background image and multiple handwriting frames are merged into a single MMS message transmission. The controller at the transmitting terminal packages the background image and handwriting frames together with their corresponding temporal information, allowing the receiving terminal to reconstruct the synchronized display of background image and handwriting animation as a unified message.
