Touch Gesture Mapping for Screen Orientation Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch screen terminals do not have a uniform touch gesture for different screen states, leading to a deteriorated user experience as users need to remember different gestures for the same operational instructions when the screen orientation changes.
Innovation Solution
A method and mobile terminal design that maintains the same touch gesture input triggering the same command across different screen orientations by using a gravity sensor to detect state changes and mapping gestures from one orientation to another, ensuring consistent gesture-based commands.

1Adaptability or versatility
If the display output interface is switched between lateral-screen state and longitudinal-screen state, then the terminal can be used in different orientations, but the user needs to remember different touch gestures for the same operational instruction in different states
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the touch gesture recognition parameters based on the detected screen orientation state. When the terminal rotates between longitudinal and lateral orientations, the system changes the parameter set for gesture recognition to maintain consistent operational semantics. For example, a swipe gesture in a specific direction in longitudinal mode corresponds to the same functional operation as the corresponding gesture in lateral mode, achieved by transforming the gesture parameter interpretation based on the current orientation state.
Solution Approach 2:
The patent implements dynamics by making the gesture recognition system adaptive and dynamic rather than static. The system continuously monitors the terminal's orientation state and dynamically adjusts which gestures are recognized and how they are interpreted. This dynamic adaptation allows the same physical gesture to trigger the same logical operation regardless of whether the terminal is in longitudinal or lateral screen state, eliminating the need for users to memorize different gestures for different orientations.
2Productivity
If different touch gestures are defined for different screen states, then each state can have optimized gesture control, but the user experience deteriorates due to lack of uniform operation gesture
Solution Approach 1:
The patent applies universality by creating a unified gesture control system that works consistently across different screen orientations. Instead of defining separate gesture sets for longitudinal and lateral modes, the system establishes a universal gesture language where the same physical gesture performs the same function regardless of orientation. This multi-functional approach allows the gesture system to serve both orientations uniformly, improving user experience while maintaining operational efficiency through consistent gesture-to-command mapping.

AI summary
A method and a mobile terminal for processing touch input are provided. The mobile terminal has a rectangular touch screen with long sides and short sides. The mobile terminal having two state: a first state in which only the short sides are parallel with a horizontal surface and a second state in which only the long sides are parallel with the horizontal surface. The method comprises the following steps of: obtaining from the touch screen a gesture in a first direction as input by a touch object on the touch screen when the mobile terminal is in the first state; triggering a first touch command in response to the gesture in the first direction; obtaining from the touch screen a gesture in a second direction as input by the touch object on the touch screen when the mobile terminal is in the second state, the second direction being the same as the first direction; and triggering the first touch command in response to the gesture in the second direction. According to the embodiments of the present invention, it is possible to achieve a uniform operation gesture for the same operational instruction by means of self-conversion of the mobile terminal, such that the user experience can be improved.
