Proximity Sensor Flying Flick Magnification for Touch Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small operated objects on touch screens, especially in systems that support both mouse and touch panel operations, can make touch operations difficult due to their size and proximity, leading to accidental selections of adjacent objects.
Innovation Solution
An electronic device with a proximity sensor and touch sensor that generates coordinates for a pointing medium, displaying a partial image of an enlarged area of the original image when a flying flick operation is detected, allowing for accurate contact coordinates to be output as if the operation was performed on the original image, thereby aiding in precise selection of small objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the touch screen displays small operated objects to fit the screen size, then the screen can display more information, but the user cannot accurately touch the small objects leading to accidental selections
Solution Approach 1:
The patent segments the touch operation into two phases: a flying flick operation to select the target operated object, and a subsequent touch operation on the enlarged partial image for precise selection. This segmentation allows the user to first identify the target from the complete screen view, then perform an accurate touch on the enlarged version, resolving the contradiction between displaying multiple small objects and maintaining touch accuracy.
Solution Approach 2:
The patent introduces a dimensional transformation by creating a partial image with enlarged operated objects that overlays on the original screen. This adds a layer of magnification dimension, allowing users to access detailed views of small objects without changing the overall screen layout or losing the context of other objects.
2Adaptability or versatility
If the system supports both mouse and touch panel operations with small operated objects, then the system has higher versatility, but touch operations become more difficult due to object size
Solution Approach 1:
The patent implements a universal solution that works for both mouse operations and touch panel operations. The flying flick operation can be performed with either a mouse cursor or a finger on the touch screen, and the partial image generation logic is the same for both input methods. This multi-functionality approach maintains system versatility while specifically addressing the touch operation difficulty.
3Ease of operation
If the user performs a flying flick operation to enlarge an area, then the user can accurately select small objects, but the system complexity increases due to additional sensors and processing
Solution Approach 1:
The patent introduces a proximity sensor as an intermediary device between the user's flying flick operation and the display system. This sensor detects the user's intent to perform a flying flick operation and triggers the partial image generation. The intermediary approach allows the system to respond intelligently to user actions without requiring complex built-in processing, as the proximity sensor provides the necessary trigger information.
