Multi-Touch Scheme Segmentation for Mobile Terminal Usability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face limitations in space allocation for user interfaces due to mobility and portability requirements, making it challenging to perform both input and output functions effectively with a full-scale touchscreen.
Innovation Solution
A mobile terminal and controlling method that utilizes at least two multi-touch schemes to control operations on a touchscreen, allowing for detailed interactions such as altering the shape, size, and position of 3D objects, as well as zooming and shifting map regions, by maintaining touches on specific parts of the content and moving touches in certain directions.

Engineering Contradiction Analysis
1Ease of operation
If a full-scale touchscreen is applied to a mobile terminal, then input and output functions are improved, but the terminal size and portability are worsened
Solution Approach 1:
The patent segments the touchscreen into multiple functional zones with different touch schemes. The first touch scheme handles basic selection operations on specific regions, while the second touch scheme handles navigation and manipulation operations on other regions. This segmentation allows the small touchscreen to provide diverse functions without requiring a large display area.
Solution Approach 2:
The patent introduces dynamic touch schemes where the same physical touch can be interpreted differently based on the region and scheme. By dynamically switching between first and second touch schemes depending on the touched region, the system maximizes the functionality of each pixel, allowing sophisticated operations on a compact display.
2Measurement precision
If multiple touch schemes are implemented to control content operations, then operational precision is improved, but device complexity is worsened
Solution Approach 1:
The patent applies different touch schemes locally to different regions of the touchscreen. The first touch scheme is applied to specific regions for selection operations, while the second touch scheme is applied to other regions for navigation operations. This local differentiation enables precise control without requiring complex global control mechanisms.
Solution Approach 2:
The patent makes the touchscreen universally functional by implementing multiple touch schemes that can handle different operation types (selection, navigation, manipulation) on a single device. This multi-functionality reduces the need for separate controls for different operations, thereby reducing overall system complexity while improving operational precision.

AI summary
The present invention relates to a mobile terminal including a touchscreen configured to display content on a screen and a controller controlling operations related to the content. The touchscreen receives a touch input comprising a touch of at least one first part of the content according to a first touch scheme and receives a touch input comprising a touch of at least one second part of the content according to a second touch scheme. If the touch according to the second touch scheme is altered, the controller controls an operation of the content according to the altered touch of the second touch scheme.
