Mobile Touchscreen Partial Region Capture Using Dual-Touch Hold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals cannot capture or record specific partial regions of the screen information without first capturing the entire region and then editing it, limiting user convenience and efficiency.
Innovation Solution
A mobile terminal that allows users to select and set a partial region on the touch screen using dual touch inputs maintained for a reference time, enabling functions like capturing or recording the selected region through preset conditions applied via touch inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire region of screen information is captured or recorded, then the complete screen content is obtained, but the user cannot selectively capture or record only the desired partial region
Solution Approach 1:
The patent divides the screen capture function into two stages: first, the user selects a partial region of interest on the touch screen; second, the system captures or records only that selected region. This segmentation allows users to obtain only the necessary information without capturing the entire screen, thereby improving operational ease and reducing time loss.
Solution Approach 2:
The patent requires the user to perform a preliminary selection action by touching and holding the start point, then moving to and touching the end point to define the partial region before initiation of the capture or recording operation. This preliminary action enables precise region specification, allowing the system to subsequently capture only the desired area without requiring post-capture editing.
2Ease of operation
If the user selects a partial region by touching and holding points, then the desired region can be captured, but the operation becomes more complex
Solution Approach 1:
The patent enables the touch screen to automatically interpret and execute region selection based on simple user touch patterns. When a user touches and holds a start point, then moves to and touches an end point, the system automatically defines the partial region without requiring additional manual configuration or complex interface interactions. This self-service mechanism simplifies the operation while maintaining precise region selection capability.

AI summary
Disclosed are a mobile terminal having a display unit for outputting screen information and capable of enhancing a user's convenience related to the screen information, and a method for controlling the same. The mobile terminal includes: a touch screen configured to display screen information; and a controller configured to select a region of the touch screen based on first and second touch inputs when the first and second touch inputs applied to different points of the touch screen are maintained for a reference amount of time without being released, and configured to execute a function related to the selected region when a touch input corresponding to a preset condition is applied to the touch screen while the first and second touch inputs are maintained without being released.
