Auto-scrolling Input Area for Dual-Display Touch Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience frustration when inputting on a touchscreen device with a stylus, as they need to manually scroll the input area when it reaches the edge, often requiring two hands and interrupting the flow of input.
Innovation Solution
A computing device with two touch-sensitive display devices and an auto-scroll module that automatically scrolls the input area based on user input, recognizing text and inserting it into a text area, allowing continuous input without manual scrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual scrolling is implemented when input area reaches edge, then input area boundary is maintained, but input flow is interrupted and user experience deteriorates
Solution Approach 1:
The system automatically detects when input approaches the input area boundary and autonomously scrolls the content without requiring user intervention. The processor monitors input position and triggers scrolling operations automatically, allowing the system to serve itself rather than requiring manual user action to maintain continuous input flow.
Solution Approach 2:
The system continuously monitors the position of input within the input area and provides feedback by automatically initiating scrolling when the input approaches the boundary. This closed-loop feedback mechanism ensures the input area boundary is maintained while preventing interruption of the input flow, as the system responds to boundary conditions with appropriate scrolling actions.
2Ease of operation
If two hands are required for input (one for stylus, one for scrolling), then scrolling control is improved, but operation complexity increases
Solution Approach 1:
The system eliminates the need for dual-hand operation by implementing automatic scrolling that responds to input position. The processor autonomously determines when scrolling is needed and executes the scrolling operation, reducing the interaction from two-handed coordination to single-handed stylus input only.
Solution Approach 2:
The patent replaces the mechanical dual-hand scrolling operation with an automated electronic system. Instead of requiring physical manual scrolling gestures, the system uses processor-based detection of input position and automated scrolling commands, substituting mechanical user action with electronic control logic.

AI summary
In some implementations, a computing device may include a first display device and a second display device that are both touch sensitive devices. An auto-scroll module executing on the computing device may create an input area on at least one of the first display device or the second display device based on an orientation of the computing device. The auto-scroll module may automatically scroll the input area as input is received in the input area. The automatic scrolling may include removing a portion of the input being displayed in the input area, recognizing text in the portion of the input, and displaying the text in a text area of a window associated with an application.
