Remote Mouse Control via Touch Gesture Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch panel-based mouse function methods for mobile terminals lack intuitiveness, requiring users to perform pan or scroll gestures while pressing hard or soft keys with another touch tool, leading to user inconvenience.
Innovation Solution
A remote mouse function method and terminal configuration that allows intuitive and convenient control using a touch panel-equipped mobile terminal, where touch gestures are translated into mouse actions, enabling pan, scroll, and other mouse functions without the need for pressing keys, by differentiating between single, multi-touch, tap, and drag gestures and transmitting corresponding commands to an output terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional touch panel-based mouse function methods are used to implement mouse functionalities, then the basic mouse functions (left/right buttons and wheel) can be provided, but the operation becomes non-intuitive and inconvenient for users
Solution Approach 1:
The patent copies the natural touch gestures used for mobile terminal operations and applies them to remote mouse control. Single-touch gestures control the pointer, while two-touch gestures control object manipulation, creating an intuitive mapping between familiar mobile interactions and mouse functions without requiring users to learn new operation modes
Solution Approach 2:
The system dynamically switches between different operation modes based on the number of touch points detected. When one touch point is detected, the system enters pointer control mode; when two touch points are detected, it switches to object control mode. This dynamic adaptation allows the same touch panel interface to serve multiple functions intuitively
2Adaptability or versatility
If pan or scroll gestures are implemented while pressing hard or soft keys, then mouse button functions can be activated, but the operation becomes inconvenient requiring multiple touch tools
Solution Approach 1:
The patent merges the functions of mouse buttons and object manipulation into a unified touch gesture system. Instead of requiring separate actions for button pressing and gesture input, the system combines these into single cohesive gestures: one-touch for pointer control and two-touch for object control, eliminating the need for multiple touch tools or complex coordinated actions
3Adaptability or versatility
If a touch panel-equipped mobile terminal is used as a remote mouse, then portability and touch interface advantages are gained, but the lack of intuitive operation reduces usability
Solution Approach 1:
The patent changes the operational parameters of the touch panel by detecting the number of touch points as the key distinguishing parameter. This parameter change enables the system to differentiate between pointer control operations (one touch) and object manipulation operations (two touches), creating an intuitive operation mode that leverages the natural multi-touch capabilities of modern touch panels

AI summary
A touch panel-equipped input terminal configured to be used as a mouse according to a remote mouse function method. The remote mouse function method includes displaying a mouse operation image on a screen of the display unit in response to a mouse host application execution request; detecting a touch gesture made with a touch input tool on the mouse operation image; determining, when movement of the touch input tool is detected, whether a touch hold time counted from the detection of the touch gesture is greater than a first hold threshold; and transmitting, when the touch hold time is greater than the first hold threshold, an object move command to an output terminal and, when the touch hold time is not greater than the first hold threshold, a pointer move command. The remote mouse function may also be implemented by the output terminal.
