Touch Screen Icon Display Order Based on Retention Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch screen-based user interfaces for portable terminals require multiple touches or more inputs, making it difficult for users to operate them efficiently with one hand, especially when using a single touch method.
Innovation Solution
A method that sets types and display orders of icons on a touch screen, senses touch inputs, measures the retention time of touches, and displays icons accordingly, allowing for reduced input touches and enhanced user experience by controlling the arrangement, size, color, and transparency of icons based on touch input times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple touch method is used, then operation efficiency is improved, but device compatibility is limited to capacitive touch sensors only
Solution Approach 1:
The patent implements a universal touch interface system that supports both single-touch and multi-touch operations across different touch sensor types (capacitive, resistive, and other types). The controller is designed to recognize and process various touch input methods, making the device compatible with multiple touch sensor technologies while maintaining efficient operation capabilities.
2Adaptability or versatility
If single touch method is used, then device compatibility is improved, but number of input touches required increases
Solution Approach 1:
The patent implements a dynamic icon display system that adapts its behavior based on touch input characteristics. When a single touch is detected, the system dynamically changes the display order and visibility of icons based on their usage frequency and importance. Frequently used icons are displayed first, allowing single-touch operations to access common functions efficiently without requiring multiple sequential touches.
Solution Approach 2:
The system pre-arranges icons in the display based on their usage frequency and importance before user interaction. This preliminary ordering ensures that the most commonly accessed functions are immediately visible and accessible with a single touch, eliminating the need for multiple sequential touches to navigate through less important icons.
3Quantity of substance
If more touch inputs are required, then icon display completeness is improved, but user operation complexity increases
Solution Approach 1:
The patent applies local quality by displaying different numbers and types of icons in different regions or positions on the screen based on their usage frequency and importance. High-frequency icons are placed in prominent, easily accessible positions, while less frequently used icons are positioned elsewhere or displayed on demand. This localized optimization allows the system to maintain complete icon functionality while reducing the operational complexity for accessing commonly used functions.

AI summary
A method for providing touch screen-based user interface and a portable terminal adapted to the method are provided. The method includes setting types and display order of icons to be displayed on a touch screen, sensing a touch input to the touch screen, measuring a time that the touch input is retained on the touch screen, and displaying at least one icon, in an order, according to the measured touch input retaining time and the set types and display order of icons. The touch screen-based user interface providing method can allow a user to easily search for and operate a corresponding function, via a relatively small number of touch inputting actions, thereby enhancing the user's experience while the user is using the portable terminal.
