Touchpad Gesture Recognition for Virtual Mouse Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laptop users face inconvenience due to the need to carry a separate mouse, and existing touch pads are not intuitive for users accustomed to traditional mouse operations, requiring a change in operating habits.
Innovation Solution
An electronic device with a sensor module that detects hand actions to execute mouse functions, allowing users to operate the device with virtual mouse functionality by detecting touch signals and corresponding hand movements, enabling functions like button clicks and cursor movement without a physical mouse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate mouse is carried for laptop users, then mouse operation convenience is improved, but portability and ease of carrying deteriorate
Solution Approach 1:
The patent merges the mouse functionality with the laptop's existing touch pad by detecting specific touch patterns (multi-touch gestures, touch duration, touch position) on the touch pad surface. This integration eliminates the need for a separate physical mouse while maintaining familiar mouse-like operation conventions through software interpretation of touch gestures.
Solution Approach 2:
The patent creates a virtual mouse interface by mapping touch pad gestures to traditional mouse functions. It copies mouse behavior patterns (clicking, dragging, scrolling) into the touch pad interaction model, allowing users to operate the device with mouse-like habits without requiring a physical mouse.
2Weight of moving object
If a touch pad is used to substitute the mouse, then portability is improved, but ease of operation deteriorates due to unfamiliar control methods
Solution Approach 1:
The patent copies traditional mouse operation semantics into the touch pad interface by recognizing specific touch patterns that correspond to mouse actions. For example, certain multi-touch gestures are interpreted as left-click, right-click, or scroll operations, making the touch pad feel familiar to mouse users while maintaining the device's portability.
Solution Approach 2:
The patent changes the operational parameters of the touch pad by introducing multi-touch gesture recognition, touch duration detection, and positional sensitivity. These parameter changes enable the touch pad to respond to complex hand actions that mimic mouse behavior, bridging the gap between touch pad portability and mouse-like ease of operation.
3Ease of operation
If traditional mouse functions are implemented on touch pad, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by having the touch pad controller directly process and interpret touch gestures using embedded algorithms. The system automatically recognizes touch patterns and maps them to mouse functions without requiring complex external processing, reducing overall system complexity while maintaining ease of operation.
Solution Approach 2:
The patent segments the touch pad functionality into distinct gesture types (e.g., single-touch, multi-touch, long-press, swipe) and assigns specific mouse functions to each segment. This modular approach simplifies the software architecture by handling different gestures independently rather than requiring a monolithic complex processing system.

AI summary
A method for executing a mouse function of electronic device and an electronic device thereof are provided. In the present method, an amount and a relative position of input signals are detected by a sensor module. Then, whether the amount and the relative position are respectively conformed to a predetermined value is determined. If the predetermined values are conformed, whether the input signal is conformed to a specific signal is determined when a variation of the relative position is occurred. Finally, a corresponding mouse function is executed according to a type of the variation if the variation is conformed to the specific signal. As a result, a mouse device is no longer needed for a user to accomplish a directional operation on the electronic device so as to prevent inconvenience of particularly carrying a mouse device.
