Touchpad Gesture Control for Function Switching and Input Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The touchpad on notebook computers, which often serves multiple functions including a numeric interface, experiences inconvenient function switching and input errors due to the complexity of user interface management.
Innovation Solution
A control method for a user interface on an electronic device that includes a touch element with a start area, a trigger area, and a track area, where touch behavior is used to generate continuous touch data to enter a startup interface display mode, activate an animation mode, and open a user interface, enhancing user experience and convenience by allowing intuitive gesture-based interaction without disrupting original operations.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple functions are added to the touchpad (such as numeric interface), then the functionality and versatility of the device is improved, but the user interface management becomes complex and function switching becomes inconvenient
Solution Approach 1:
The touchpad surface is segmented into distinct functional areas (numeric area, trigger area, track area) with specific gesture protocols for each. This segmentation allows multiple functions to coexist without interfering with each other, as each area has dedicated gesture commands that prevent confusion and simplify user interface management.
Solution Approach 2:
The system dynamically adjusts the interpretation of touch gestures based on the current functional mode and the specific area touched. The touchpad can switch between different operational states (numeric input mode, cursor control mode, etc.), where the same physical touch area may have different meanings depending on the active mode, allowing versatile functionality without permanent interface complexity.
2Adaptability or versatility
If multiple functions are added to the touchpad, then the versatility is improved, but input errors increase due to incorrect user interface selection
Solution Approach 1:
Different areas of the touchpad are assigned different functional qualities and gesture requirements. For example, the numeric area requires specific multi-finger gestures distinct from the trigger area gestures. This local differentiation ensures that gestures performed in one area cannot accidentally activate functions in another area, thereby preventing input errors while maintaining versatility.
Solution Approach 2:
The system provides visual feedback on the display screen that corresponds to the touch gestures performed on the touchpad. This feedback mechanism helps users confirm that their gesture was correctly interpreted and activates the intended function, reducing input errors caused by misinterpretation of touch inputs.
3Adaptability or versatility
If function switching is added to accommodate multiple interfaces, then the versatility is improved, but the operation becomes more complicated
Solution Approach 1:
The patent merges the function switching mechanism with the existing touch gesture system. Instead of adding separate controls for switching between numeric interface and cursor control, the system uses different gesture patterns (single-finger vs. multi-finger, different swipe directions) to directly activate different functions. This integration eliminates the need for separate switching controls, maintaining operational simplicity while achieving versatility.

AI summary
A controlling method of a user interface and an electronic device are provided. A touch element includes a start area, a trigger area and a track area connecting the start area and the trigger area. The controlling method of the user interface includes following steps: entering a startup interface display mode according to the touch behavior performed on the touch element; generating continuous touch data in response to the touch behavior when the touch behavior moves from the start area to the track area and an animation trigger condition is satisfied, activating an animation mode according to the continuous touch data; and generating the continuous touch data in response to the touch behavior when the touch behavior moves from the start area to the track area and from the track area to the trigger area, and opening a user interface according to the continuous touch data.
