Dynamic Icon Sizing for Portable Display Input Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The small size of icons on portable devices like PDAs makes it difficult for users to select the correct application, often leading to incorrect activations, especially when an input device is not available or improperly calibrated, resulting in user frustration and inefficiency.
Innovation Solution
A target size adjustment circuit that detects the presence of an input device and adjusts the size of icons on the display accordingly, providing larger targets when the input device is present and smaller targets when it is not, allowing for easier selection with a fingertip or input device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the display size is kept small for portable devices, then the device portability is improved, but the icon size becomes too small for accurate selection
Solution Approach 1:
The patent applies dynamics by making the icon size adjustable rather than fixed. The system dynamically changes icon size based on the detected input device type - using smaller icons when a stylus is detected and larger icons when a fingertip is detected, allowing the display to adapt its characteristics to match the user's interaction method while maintaining portability
Solution Approach 2:
The patent changes the parameter of icon size based on detected input conditions. By monitoring whether an input device is present and adjusting the icon dimensions accordingly, the system optimizes the balance between display density and selection ease without changing the physical display size of the device
2Ease of operation
If the icon size is made larger for easier selection, then the ease of operation is improved, but the number of icons that can be displayed decreases
Solution Approach 1:
The system dynamically adjusts icon size based on real-time detection of the input device. When a stylus is detected, icons are displayed at normal size to maximize quantity; when a fingertip is detected, icons are enlarged to improve selection ease, thus adapting the display to current usage conditions
Solution Approach 2:
The patent implements parameter changes by varying the icon size parameter based on input device detection. This allows the system to optimize either icon quantity or icon selectability depending on whether an input device is present, rather than being fixed in one state
3Device complexity
If the same icon size is used for all input methods, then the device complexity is reduced, but the user frustration increases due to incorrect selections
Solution Approach 1:
The system changes the icon size parameter based on detected input conditions to improve selection accuracy. By detecting whether a stylus or fingertip is used and adjusting icon dimensions accordingly, the system reduces incorrect selections while adding only minimal complexity through automatic detection and adjustment mechanisms
