Stylus Air Pointer Stabilization via Preliminary Position Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Delicate pointing by an air pointer on an electronic device using a stylus pen is not as precise as with a normal mouse, and pressing a button on the stylus pen can cause the air pointer to move, leading to unclear selection.
Innovation Solution
An electronic device with a processor that identifies air pointer initiation events, displays an air pointer based on rotation information and application data, calculates position information for selection events, and performs functions corresponding to the selected object, ensuring clear pointing and object selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a button press operation is performed on the stylus pen to select an object, then the selection function is activated, but the stylus pen moves due to the pressing operation causing the air pointer position to change and clear pointing to fail
Solution Approach 1:
The system performs preliminary action by capturing and storing the air pointer position information at the moment the button press operation is detected, before the stylus pen movement occurs. This pre-captured position data is then used for object selection, ensuring that the selection is based on the intended pointer position rather than the position after movement, thus resolving the contradiction between ease of operation and positioning accuracy
2Adaptability or versatility
If the air pointer is used for delicate pointing operations, then wireless stylus control is enabled, but the pointing precision is not as good as with a normal mouse
Solution Approach 1:
The system implements feedback by continuously receiving air gesture information from the stylus pen and updating the air pointer position on the display in real-time. This feedback mechanism allows the user to see the pointer response to their gestures, enabling better control and precision for delicate pointing operations, thereby improving pointing accuracy while maintaining wireless stylus versatility
