Virtual Touch Area Mapping for Cursor Control Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cursor control methods, such as mouse and touchpad interfaces, require significant wrist movement and time for accurate click operations, leading to inefficiency in cursor positioning and operation.
Innovation Solution
A cursor control method and system that detects a click position on a touch device, calculates a virtual click coordinate position in a corresponding virtual touch area on a display device, and performs the click operation at that position, thereby reducing wrist movement and operation time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user moves the mouse to the target location and adjusts the mouse position slightly to accurately reach the specified button position, then the cursor positioning precision is improved, but the wrist movement and operation time increase
Solution Approach 1:
The patent creates a virtual copy of the touch area on the display device. The virtual touch area replicates the physical touch area's coordinate system, allowing the cursor to be positioned directly at the corresponding virtual location without requiring physical mouse adjustment. This copying approach enables precise cursor positioning while eliminating the need for additional wrist movements to fine-tune the cursor position.
2Measurement precision
If the user moves the mouse to the target location and adjusts the mouse position slightly to accurately reach the specified button position, then the cursor positioning precision is improved, but the wrist movement and operation time increase
Solution Approach 1:
By copying the touch area coordinates to the display device, the system eliminates the disconnect between physical mouse position and cursor position. Users no longer need to perform fine adjustment movements because the virtual touch area directly maps to the corresponding display location, making the operation simpler and more intuitive.
Solution Approach 2:
The virtual touch area acts as an intermediary between the physical touch area and the display device. It translates touch coordinates into corresponding display coordinates, serving as a bridge that eliminates the need for manual adjustment and simplifies the user's interaction with the system.
3Productivity
If a virtual touch area is introduced to map touch coordinates to display coordinates, then the operation efficiency is improved, but the device complexity increases
Solution Approach 1:
The virtual touch area serves multiple functions: it maps touch coordinates to display coordinates, positions the cursor accurately, and enables direct click operations. By making this single component multi-functional, the system achieves improved operation efficiency without proportionally increasing device complexity, as one component handles multiple tasks rather than requiring separate systems for each function.

AI summary
A cursor control method is disclosed. The cursor control method is applicable for a touch device and a display device, in which the display device includes a virtual touch area corresponding to a touch area of the touch device. The control method includes the following operations; detecting a click position in the touch area during a click operation; calculating a virtual click coordinate position corresponding to the click coordinate position in the virtual touch area; and performing the click operation at the virtual click coordinate position on the display device.
