Dynamic Stylus Input Area Adjustment on Touch Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional large-sized touchpads with fixed sensing input areas fail to adapt to different hand sizes and drawing habits, limiting user freedom when using a stylus for writing or drawing.
Innovation Solution
An electronic device with a display panel, touch module, and processor that dynamically adjusts the effective input area based on stylus location and detection modes, displaying a range marking pattern to clearly indicate the input area, allowing users to set preferred input configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sensing input area on the touchpad is fixed in location and size, then the device structure is simple, but it fails to adapt to different hand sizes and drawing habits, limiting user freedom
Solution Approach 1:
The patent implements a dynamic effective input area that can be adjusted based on user needs. The processor dynamically defines the location and size of the effective input area within the touchable area, allowing the sensing region to adapt to different hand sizes and drawing habits rather than being fixed. This resolves the contradiction by making the input area flexible and adaptable while maintaining a relatively simple overall device structure.
Solution Approach 2:
The patent changes the parameters of the effective input area (location and size) based on detected stylus position and user interaction patterns. By dynamically adjusting these parameters, the system adapts to different users and usage scenarios without requiring complex hardware modifications, thus improving adaptability while controlling device complexity.
2Ease of operation
If the effective input area is dynamically adjusted based on stylus location, then user convenience is improved, but the device requires complex detection and switching mechanisms
Solution Approach 1:
The system automatically detects stylus position and dynamically adjusts the effective input area without requiring manual user configuration. The processor monitors stylus location and autonomously defines appropriate input areas, making the system self-adapting and easy to use while minimizing the need for complex user-facing controls or configuration mechanisms.
Solution Approach 2:
The system uses feedback from stylus position detection to dynamically adjust the effective input area. The processor continuously monitors stylus location and uses this feedback information to define appropriate input areas, creating a closed-loop system that improves ease of operation through automatic adaptation rather than requiring complex manual adjustment mechanisms.
3Loss of information
If the effective input area is clearly marked with range marking patterns, then user awareness of input boundaries is improved, but the display complexity increases
Solution Approach 1:
The patent uses visual marking patterns (which may include color changes or graphical indicators) to clearly delineate the effective input area boundaries on the display. These markings provide users with clear visual feedback about where input will be effective, improving boundary awareness without requiring complex additional hardware. The markings are rendered software-based on the display panel, keeping the physical device structure relatively simple.
Data Source
AI summary
The disclosure provides an electronic device adapted to communicate with a stylus. The electronic device includes a display panel, a touch module, and a processor. The display panel has a display area, the touch module has a touchable area, and the processor is electrically connected to the display panel and the touch module. The processor is configured to: define at least one effective input area in response to an operation of the stylus in the touchable area, and when the touch module detects that the stylus is approaching the effective input area, switch the effective input area to a stylus mode, and display a range marking pattern in the effective input area.
