Touch Interface Command Selection via Spatial Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices with touch interfaces can only process a limited number of commands based on single touch actions, restricting the functionality of user interactions.
Innovation Solution
A method and system for processing sequences of touch actions, where the initiation and completion locations, types, and rates of multiple touch actions are analyzed to select and execute corresponding commands, enabling more complex user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single command is mapped to a single touch action, then the system is simple to operate, but the number of commands that can be performed is limited
Solution Approach 1:
The patent segments the touch interface into multiple zones (first region, second region, third region) and assigns different commands to different zones. This allows multiple commands to be executed through spatial segmentation of the touch interface, increasing the number of performable commands without requiring complex multi-action sequences.
Solution Approach 2:
The patent introduces a spatial dimension to command selection by dividing the touch interface into multiple regions. Instead of relying solely on sequential touch actions, the system uses the spatial dimension (different zones of the touch screen) to differentiate between commands, thereby expanding command capacity while maintaining operational simplicity.
2Adaptability or versatility
If multiple commands are enabled through touch action sequences, then the functionality is enhanced, but the system complexity increases
Solution Approach 1:
The patent segments both the touch interface into multiple zones and the command set into zone-specific commands. This segmentation allows the system to handle multiple commands through simple spatial differentiation rather than complex temporal sequencing, reducing processing logic complexity while maintaining command variety.
Solution Approach 2:
The touch interface is designed with multi-functionality where different zones serve different command purposes. The same touch interface hardware performs multiple commands by utilizing its spatial versatility, allowing a single touch interface to handle diverse commands without increasing hardware or processing complexity.

AI summary
A system and method for processing touch actions are provided. A plurality of sequentially performed touch actions including a first touch action and a second touch action are determined on a touch interface of an electronic device. An initiation location and a completion location of each of the first and second touch actions are determined on the touch interface. A command is selected based on the determined completion location of the first touch action, the second touch action, and the determined initiation location of the second touch action. The selected command is executed on the electronic device.
