Divided Display Interaction for Foldable Screen Multi-Touch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive systems with hyper-curved or foldable screens face challenges in user interaction, particularly when operations require multiple touches or simultaneous interactions on different screen locations, leading to suboptimal user experience.
Innovation Solution
A display method that divides the screen into a display area and an extension area, allowing operations in the extension area to be mapped and responded to in the display area, through event information generation and processing, enhancing interaction by correlating touch events across these areas.

1Area of stationary object
If the screen size is increased to improve user experience, then the display area is enlarged, but the difficulty of operation increases when requiring multiple touches or simultaneous interactions on different screen locations
Solution Approach 1:
The display screen is segmented into a display area and an extension area. The extension area can be virtually or physically separated from the main display area, allowing independent interaction zones. This segmentation enables users to perform different operations in different areas simultaneously, reducing the complexity of multi-touch interactions on large screens.
Solution Approach 2:
The extension area acts as an intermediary zone between the user and the main display area. Operations performed in the extension area can be mapped to corresponding positions in the display area, providing a buffer zone that simplifies interaction by allowing users to access screen functions from peripheral locations without directly touching the main display area.
2Ease of operation
If the screen is divided into display area and extension area, then the ease of operation is improved through single-hand operations, but the device complexity increases due to additional area division and event mapping mechanisms
Solution Approach 1:
The extension area serves multiple functions: it can be used for additional display content, as a virtual keyboard area, for gesture recognition, or for mapping operations to the main display area. This multi-functionality reduces the need for separate components for each function, thereby limiting the increase in system complexity.
Solution Approach 2:
The system dynamically adjusts the boundary and functionality of the extension area based on user needs and application requirements. The division between display area and extension area is not fixed but can be reconfigured, allowing the system to adapt to different usage scenarios without requiring hardware changes, thus controlling complexity.
3Ease of operation
If event information is generated and mapped from the extension area to the display area, then the interaction experience is improved, but the loss of time increases due to additional processing steps
Solution Approach 1:
The system pre-establishes mapping relationships between the extension area and the display area during initialization or configuration phases. Common operation mappings are pre-configured, so when a user interacts with the extension area, the system can quickly retrieve and apply the corresponding mapping without performing complex real-time calculations, thereby reducing processing time.
Solution Approach 2:
The patent replaces complex real-time coordinate transformation and event mapping calculations with pre-computed lookup tables or simplified mapping algorithms. This substitution of complex computational mechanics with simpler data retrieval and transformation processes significantly reduces the time required to process events from the extension area.

AI summary
An interactive system includes a display, and the a display method for the interactive system includes: determining a display area and an extension area that are obtained by dividing the display; generating event information based on an operation performed by a user on the extension area; and responding, in the display area based on the event information, to an operation corresponding to the event information.
