Touch Screen Mode Icon and Displacement Value Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals with touch screens lack user convenience in displaying information corresponding to touch inputs, as existing methods do not effectively differentiate between various modes and displacement values, leading to confusion and inefficient operation.
Innovation Solution
A method where a current mode icon and displacement value are displayed on a touch screen, with the mode determined by touch input coordinates and movement direction, allowing for intuitive mode selection and execution through distinct visual cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch screen is used for input operations, then user convenience is improved, but information display clarity deteriorates
Solution Approach 1:
The patent segments information display by showing displacement values and mode icons separately and distinctly on the touch screen. The displacement value indicating movement distance is displayed in one location, while the mode icon indicating the current operation mode is displayed in another location, preventing information confusion and maintaining clarity despite the comprehensive touch input functionality.
2Device complexity
If multiple functions are integrated in single display unit, then device complexity is reduced, but mode differentiation capability deteriorates
Solution Approach 1:
The patent employs distinct visual representations for different modes and information types. Mode icons use different graphical symbols to represent different operation modes (such as pan mode, zoom mode, rotate mode), and displacement values are displayed with clear visual distinction, enabling users to easily differentiate between modes and understand current operations without additional physical controls.
3Adaptability or versatility
If touch area movement is used for input, then operation flexibility is improved, but input precision deteriorates
Solution Approach 1:
The patent implements real-time feedback by displaying the displacement value that indicates the exact movement distance of the touch area on the touch screen. This visual feedback allows users to precisely control and monitor their input actions, enabling accurate operations such as precise zooming or positioning while maintaining the flexibility of touch-based input methods.

AI summary
A method of displaying information in a mobile terminal having a touch screen is provided. The method includes determining whether a touch input is generated by a touch screen; determining, if a touch input is generated by a touch screen, whether a touch area moves; and while the touch area moves: executing a function according to an extent of the touch area movement; and displaying, while moving the touch area, at least one of a displacement value generated by executing the function and an icon indicating the executed function.
