Time-Based Touch Screen Input Recognition for Multi-Function Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch screens lack the ability to perform functions equivalent to a computer mouse's center or right click without complex menu navigation, leading to decreased user efficiency and an undesirable user experience.
Innovation Solution
Implementing time-based touch screen input recognition, where the length of a touch on the screen corresponds to specific functions, with configurable time periods and user-indicated feedback, allowing for the execution of various commands like left, center, or right clicks through a single touch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If touch screens use complex menu selections to perform additional functions (center click, right click), then the device can perform more functions, but the user efficiency decreases and user experience becomes undesirable
Solution Approach 1:
The patent applies parameter changes by using the duration of the touch gesture as a variable parameter to differentiate between different commands. Short touches, medium touches, and long touches each trigger different functions (e.g., left click, center click, right click), eliminating the need for complex menu selections and improving user efficiency while maintaining full functionality.
2Adaptability or versatility
If touch screens use complex menu selections to perform additional functions, then the device can perform more functions, but the navigation time increases
Solution Approach 1:
The system changes the parameter of touch duration to encode different commands. By measuring how long the user holds the touch gesture, the system can immediately execute the appropriate function without requiring the user to navigate through menus, thereby reducing navigation time while preserving full functionality.
3Device complexity
If touch screens lack physical buttons, then the device design is simplified, but the ability to perform specific functions (center click, right click) is limited
Solution Approach 1:
The patent replaces the mechanical button system with a touch-based gesture recognition system. Instead of relying on physical buttons with different positions, the system uses temporal parameters of a single touch gesture to differentiate between various click functions, thereby maintaining simplified device design while achieving full functionality.
Solution Approach 2:
The system uses touch duration as a parameter to substitute for the functional differentiation provided by physical buttons. By varying the length of the touch gesture, users can access different functions that would traditionally require multiple physical buttons or menu navigation, thus maintaining design simplicity while achieving versatility.

AI summary
A time based touch screen input recognition system detects a touch on a touch screen display by receiving a first signal indicating a start of the touch and starts a timer in response to the first signal. The system monitors a length of the touch as the touch continues, determines a current time period covering the length of the touch using a current value of the timer and identifies a first function corresponding to a current time period. The system further identifies a second function corresponding to a second signal indicating an end of the touch and causes a processing device to implement the corresponding function.
