Touch Input Interface Writing Area Expansion Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic board devices have fixed page sizes, which can become insufficient during writing, leading to inconvenience for users who cannot expand the writing area.
Innovation Solution
An electronic device with a touch input interface that detects predefined touch inputs to reduce the current writing area and provide an extended area for continued input, adjusting the size based on input parameters such as duration, pressure, or number of touches, and optionally confirming user intent before expanding the space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the writing area is fixed in size, then the device structure is simple and stable, but the user cannot expand the writing space when needed
Solution Approach 1:
The system automatically detects when the writing area needs expansion by monitoring touch input patterns (such as touching the edge area for a predetermined time) and autonomously provides the extended area without requiring users to manually adjust settings or navigate complex menus, making the expansion process self-service and intuitive
Solution Approach 2:
The writing area transitions from a fixed static state to a dynamic adjustable state, where the system can automatically expand or reduce the writing area based on detected touch inputs, allowing the interface to adapt flexibly to user needs while maintaining operational simplicity
2Area of stationary object
If the writing area is reduced to provide extended area, then additional writing space is available, but the original writing content occupies less screen space
Solution Approach 1:
The system manages the transition of writing area by reducing the original writing area in one dimension and providing the extended area in another dimension (such as extending to the edge of the display), effectively utilizing the display space while maintaining both the original and extended writing areas
3Adaptability or versatility
If the page size is fixed, then the document structure is stable, but the user cannot accommodate longer writing content
Solution Approach 1:
The extended area is implemented as a separate segment from the original writing area, allowing the system to maintain the stability of the original page structure while adding additional segmented space for extended content, thus preserving document structure integrity while increasing content capacity

AI summary
An electronic device having an electronic board function and an operation method thereof. The electronic device includes: a display; a touch input interface; a memory storing at least one instruction; and a processor configured to execute the at least one instruction stored in the memory to: display a writing area in a display area of the display; detect a predefined touch input in the writing area; and based on detecting the predefined touch input, reduce the writing area, display the reduced writing area in at least first part of the display area and provide an extended area in at least second part of the display area, the extended area being configured to receive a writing input continuing from the reduced writing area to the extended area.
