Mobile Terminal Video Memo Input via Touch Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals lack a convenient method for inputting and managing memos while recording or playing videos, as users often find it difficult to pause the video preview screen to input handwritten notes effectively.
Innovation Solution
A mobile terminal with a touch screen that outputs a preview screen of recorded video, allowing users to pause the screen and store touch paths as handwriting memos, which are then included in the recorded video, enabling convenient memo input and playback synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a video preview screen is displayed during recording, then users can monitor the recording in real-time, but users cannot input handwritten memos effectively because the screen is occupied by the video preview
Solution Approach 1:
The touch screen dynamically switches between displaying the video preview and accepting handwriting input. When handwriting input is detected, the system pauses the video preview and activates the handwriting interface, allowing users to input memos during video recording without permanent screen occupation by the preview
2Ease of operation
If the video preview screen is paused for memo input, then users can input memos more easily, but the video recording process is interrupted
Solution Approach 1:
The system automatically pauses the video preview before handwriting input begins and automatically resumes it after input completes. This preliminary action of pausing the preview creates the necessary condition for comfortable memo input while ensuring the video recording continues uninterrupted in the background
Solution Approach 2:
The video recording continues continuously in the background while the preview is temporarily paused. The useful action of video capture is maintained without interruption, while the preview display is temporarily suspended to allow memo input, then automatically resumed

AI summary
The present invention relates to a mobile terminal capable of receiving a memo while recording a video. Specifically, the present invention relates to a mobile terminal including a camera, a touch screen and a controller. When a video is recorded using the camera, the controller is configured to control the touch screen to output a preview screen of the camera. If a touch and drag input is received on the outputted preview screen, the controller is configured to temporarily stop outputting the preview screen and store a touch path of the touch and drag input as a handwriting memo which is included in the recorded video.
