Touch Pad Drag Movement Correction for Scrolling Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operability of information processing apparatuses such as tablet PCs and smartphones is not sufficiently improved by existing GUI technologies, leading to demands for enhanced user interaction and navigation, particularly in scrolling and icon arrangement tasks.
Innovation Solution
The implementation of an apparatus with an operation unit, a movement amount correction unit, and a display control unit that enhances the movement amount of drag operations on touch pads, allowing for increased scrolling efficiency and intuitive icon arrangement by modifying the display based on corrected movement amounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the movement amount of drag operation is increased, then scrolling efficiency and navigation speed are improved, but precision control and accuracy of icon placement deteriorate
Solution Approach 1:
The system dynamically adjusts the movement amount based on the type of operation being performed. For scrolling operations, a larger movement amount is applied to improve efficiency, while for icon placement operations, a smaller movement amount is used to ensure precision. This dynamic adaptation allows the same drag operation mechanism to serve multiple purposes with different performance requirements.
Solution Approach 2:
The invention changes the parameter of movement amount according to the operation context. By modifying this parameter based on whether the user is performing scrolling or icon arrangement tasks, the system optimizes performance for each specific task type while maintaining a unified interaction model.
2Loss of time
If the movement amount of drag operation is increased, then the number of drag operations needed is reduced, but the control precision and operability for detailed tasks worsen
Solution Approach 1:
The system dynamically adapts the movement amount parameter based on the detected operation type. When scrolling is detected, a larger movement amount reduces the number of operations needed. When icon placement is detected, a smaller movement amount maintains control precision. This dynamic adjustment resolves the contradiction between reducing operation count and maintaining control precision.
3Speed
If the display is controlled according to increased movement amount, then navigation efficiency is improved, but the accuracy of position mapping between touch pad and display deteriorates
Solution Approach 1:
The invention changes the movement amount parameter based on the operation context. For navigation/scrolling operations, an increased movement amount accelerates display traversal. For positioning operations, the movement amount is reduced to maintain accurate position mapping between the touch pad and display, resolving the contradiction between navigation speed and positioning accuracy.
