Dynamic Icon Sizing for Contactless Gesture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack improved operability in detecting and processing user operations, particularly in scenarios where gestures are performed at a distance without contact, leading to inefficiencies in interaction and potential contamination of touchscreens during tasks like cooking.
Innovation Solution
An electronic device equipped with both a gesture sensor, such as a proximity sensor, and a touch sensor, which adjusts the size of icons on a display based on detected gestures and touches, enhancing user interaction by allowing gesture-based operations without contact and touch-based operations with reduced icon size for clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture detection is enabled for contactless operation, then ease of operation is improved, but device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The touch panel serves dual functions: traditional touch detection and gesture detection. By enabling the touch panel to detect both contactless gestures and contactless taps, the system achieves multi-functionality without adding separate dedicated gesture sensors, thus improving ease of operation while limiting the increase in device complexity
Solution Approach 2:
A processor acts as an intermediary between the touch panel and the user interface. It analyzes touch panel signals to distinguish between gestures and taps, and dynamically adjusts icon sizes accordingly. This intermediary processing layer enables contactless operation without requiring complex hardware changes
2Ease of operation
If icon size is increased for gesture detection, then ease of operation is improved, but display space utilization deteriorates
Solution Approach 1:
The icon size is made dynamic rather than static. Icons automatically adjust their size based on the detected user interaction mode: larger icons appear when gestures are detected, and smaller icons appear when taps are detected. This dynamic adjustment maintains ease of operation for gestures while preserving display space utilization for taps
Solution Approach 2:
The system changes the parameter of icon size based on detection results. When gesture detection is active, icons are rendered at a larger size; when tap detection is active, icons are rendered at a smaller size. This parameter change allows the same display to serve different interaction purposes efficiently
3Adaptability or versatility
If both gesture and touch detection are implemented, then adaptability is improved, but processing time increases
Solution Approach 1:
The system performs preliminary analysis of touch panel signals to determine whether a gesture or tap is intended. By pre-processing the signals and making quick determinations about interaction type, the system can rapidly switch between gesture and tap modes without significant processing delays, thus maintaining adaptability while minimizing time loss

AI summary
An electronic device includes a first sensor for detecting a gesture that does not come into contact with the electronic device, a second sensor for detecting a touch that comes into contact with the electronic device, and a controller. The controller increases the size of an icon, displayed on a display, when a gesture is detected by the first sensor. The controller increases the size of the icon in accordance with the distance to the position where the gesture detected by the first sensor is performed. The controller decreases the size of the icon when a touch is detected by the second sensor, regardless of the distance to the position where the gesture detected by the first sensor is performed.
