Dynamic Icon Sizing for Touchscreen Operation Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with multiple functions, operational errors can occur due to the large number of operation targets on the display screen, leading to accidental activation of incorrect targets.
Innovation Solution
An information processing apparatus that controls a display to display operation targets, determines the contact size of an object on the display, and enables or disables operation inputs based on the contact size, using a threshold value that can be adjusted based on the size of the operation target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If icons are displayed in large size to reduce operational errors, then ease of operation is improved, but the number of operation targets that can be displayed on the screen is reduced
Solution Approach 1:
The patent applies dynamics by making the icon size variable rather than fixed. The system dynamically adjusts icon sizes based on their importance and the user's interaction state, allowing large icons for important functions and smaller icons for less critical ones, thus resolving the contradiction between ease of operation and number of displayable targets
Solution Approach 2:
The patent implements local quality by assigning different sizes to different icons based on their specific characteristics. Important operation targets are displayed with larger sizes for easier operation, while less important targets use smaller sizes, allowing the system to accommodate more targets overall while maintaining ease of operation for critical functions
2Quantity of substance
If icons are displayed in small size to increase the number of operation targets, then the number of operation targets is improved, but operational errors increase due to difficulty in accurate selection
Solution Approach 1:
The system dynamically adjusts icon sizes based on importance levels, ensuring that critical operation targets maintain larger sizes for accurate selection even when many targets are displayed. This dynamic sizing prevents operational errors for important functions while allowing less critical targets to occupy smaller spaces
Solution Approach 2:
Different icons are assigned different sizes based on their local quality or importance. Critical operation targets receive larger display areas to ensure accurate selection, while non-critical targets use smaller areas, thus maintaining operational accuracy for important functions while increasing the total number of displayable targets
3Device complexity
If fixed icon sizes are used for all operation targets, then device complexity is reduced, but operational precision deteriorates when targets have different importance levels
Solution Approach 1:
The patent implements local quality by assigning different sizes to different icons based on their importance. Important operation targets are displayed with larger sizes for precise selection, while less important targets use smaller sizes. This differentiated approach maintains operational precision for critical functions without significantly increasing system complexity
Solution Approach 2:
The system changes the size parameter of icons based on their importance level and interaction context. By dynamically adjusting this physical parameter, the system achieves better operational precision for important targets while maintaining manageable complexity through automated size assignment rules
