Electronic Device Gesture Offset Adjustment for Dual-Screen Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-screen electronic devices face challenges in maintaining continuous data input when the position of a piece of paper relative to the auxiliary electromagnetic screen changes, leading to discontinuous written content on the main screen.
Innovation Solution
A method that senses a predefined gesture via an electromagnetic plate, determines initial and subsequent coordinates of the gesture, and calculates an offset to adjust the position of the written content on the main screen, ensuring continuous data input before and after changes in the paper's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the paper position on the electromagnetic screen changes, then the user can reposition the paper for comfort or layout, but the written content becomes discontinuous on the main screen
Solution Approach 1:
The system performs preliminary detection of a predefined gesture (such as a specific pattern drawn on the paper) before actual writing continues. By detecting this gesture and calculating the offset between the original and new paper positions, the system prepares the coordinate transformation in advance, ensuring that subsequent written content maintains continuity despite paper repositioning.
Solution Approach 2:
The system continuously monitors the position of the paper by detecting the predefined gesture, calculates the offset between the first and second sets of coordinates, and uses this offset information to adjust and correct the coordinate system in real-time. This feedback mechanism ensures that the main screen display remains synchronized with the actual paper position, maintaining content continuity.
2Reliability
If the system tracks every position change of the paper, then content continuity can be maintained, but the system complexity increases
Solution Approach 1:
Instead of tracking every possible position change of the paper, the system extracts and detects only the predefined gesture (a specific pattern or marker) on the paper. This selective detection approach simplifies the tracking system by focusing only on key reference points rather than monitoring all position changes, reducing system complexity while maintaining content continuity.
Solution Approach 2:
The system uses the predefined gesture as a reference copy or marker that represents the paper's position. By detecting this gesture and calculating its offset from the original position, the system creates a simplified coordinate transformation model that maintains content continuity without requiring complex real-time position tracking of the entire paper surface.
