Coordinate Mapping for Separate Touch and Display Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with separate touch sensitive and display units experience inaccurate cursor location due to complex movement tracks, leading to long response times and poor user experience.
Innovation Solution
An information processing method that acquires and corresponds coordinates between N points on the display unit and touch sensitive points, allowing for accurate cursor location and adjustment, enabling multi-point operations and mode adjustments to enhance user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the electronic device computes the movement track of the operating object on the touch sensitive board, then the cursor location can be determined, but the accuracy of the cursor location is affected and the response time becomes long
Solution Approach 1:
The touch sensitive board is divided into N predetermined points, each corresponding to N display points on the display unit. By segmenting the continuous touch surface into discrete reference points, the system establishes direct coordinate mappings that eliminate the need for complex movement track computations, thereby improving both cursor location accuracy and response time.
Solution Approach 2:
The correspondence relationships between touch sensitive points and display points are pre-established and stored in the system. When a touch occurs, the system directly retrieves the pre-computed coordinate mapping rather than calculating the movement track in real-time, which significantly reduces response time while maintaining accurate cursor positioning.
2Ease of operation
If the touch sensitive board and display unit are separated, then the user can operate the electronic device more easily, but the cursor location becomes inaccurate
Solution Approach 1:
N predetermined points on the touch sensitive board serve as intermediary reference elements that establish a mapping relationship with N display points on the display unit. This intermediary point system bridges the separated touch sensitive board and display unit, enabling accurate cursor location correspondence despite their physical separation.
3Adaptability or versatility
If the movement track is very complicated, then the cursor can follow complex user inputs, but the response time becomes long and user experience deteriorates
Solution Approach 1:
The patent extracts only the essential touch point coordinates from the complex movement track. Instead of processing the entire complicated movement trajectory, the system identifies and processes only the key touch points and their corresponding display coordinates, maintaining input flexibility while dramatically improving response speed.

AI summary
An information processing method and an electronic device comprising a touch sensitive unit and a display unit separated from each other are described. The electronic device includes at least a first display mode, and a second display mode suitable for the touch sensitive unit. The method includes acquiring a third display mode of the display unit at a first timing when the electronic device is turned on; detecting whether the third display mode is the second display mode or not; acquiring coordinates of each point of N points of the display unit and generating a first control instruction, when the third display mode is the second display mode, wherein N is an integer above 2; and performing the first control instruction, to correspond the coordinates of the each point of the N points to coordinates of each touch sensitive point of the touch sensitive unit.
