Unified Touch Input Processing Across Multiple Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with multiple touch screen displays cannot process touch inputs from different displays as if they were a single touch screen display, leading to malfunctions when users attempt to use them as a unified touch surface.
Innovation Solution
An electronic device with multiple touch screen displays, each having its own coordinate region, uses a processor to configure a virtual coordinate region that allows touch inputs from one display to be converted and applied as if they originated from a single display, enabling unified touch input processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple touch screen displays are used independently with separate coordinate regions, then each display can be operated separately, but touch inputs from different displays cannot be processed as unified multi-touch inputs
Solution Approach 1:
The patent merges multiple independent touch panels into a unified virtual coordinate region that encompasses all physical displays. The processor combines touch inputs from different displays by mapping them to coordinates within the virtual region, enabling unified multi-touch processing across the entire multi-display surface.
Solution Approach 2:
The patent introduces a virtual coordinate region as an intermediary layer between the physical touch panels and the processing system. This virtual coordinate system acts as a mediator that translates and integrates touch inputs from multiple independent displays into a unified coordinate framework, allowing seamless multi-touch operations.
2Adaptability or versatility
If touch inputs are processed independently by each touch panel, then the processing logic remains simple, but the system cannot recognize gestures that span across multiple displays
Solution Approach 1:
The patent extends the coordinate system from individual display dimensions to a multi-dimensional virtual coordinate space that encompasses all displays. By creating a unified coordinate framework that spans multiple physical displays, the system can recognize and process gestures that move across display boundaries as continuous two-dimensional gestures rather than separate one-dimensional inputs.
3Ease of operation
If each display maintains its own coordinate system, then display independence is preserved, but user interface consistency across displays deteriorates
Solution Approach 1:
The patent creates a universal virtual coordinate region that serves multiple functions: it maintains the physical independence of each display while providing a unified coordinate framework for touch processing. This universal coordinate system enables consistent user interface behavior across all displays, allowing the same touch gestures to work seamlessly regardless of which physical display the user interacts with.

AI summary
An electronic device includes a first touch screen display, a second touch screen display, a processor, and a memory. The memory stores therein instructions which are executed by the processor to cause the processor to convert first data and second data related to touch inputs to the first touch screen display and the second touch screen display to first virtual data and second virtual data, respectively, based on a third coordinate region, and apply an action corresponding to a first touch input and a second touch input to the first touch screen display and the second touch screen display, respectively, based on the first virtual data and second virtual data. In addition, various embodiments may be realized based on a specification.
