Electronic Pen State Detection for Automatic Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with touch screens require multiple operations to pause and resume use with an electronic pen, such as turning the device on and off, which is inefficient.
Innovation Solution
An electronic device with a programming module that detects the state information of an electronic pen, including its coordinate, time, and slope, to automatically change the display state, such as turning it off or on, based on user interaction, reducing the need for manual operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the display is turned off when the electronic pen is put down, then power consumption is reduced, but the user must perform multiple operations to resume use
Solution Approach 1:
The system performs preliminary detection of the electronic pen's state (whether it is placed on the display or removed) before transitioning the display to a turned-off state. This preliminary action allows the system to automatically determine when to pause or resume display operations without requiring user intervention, thus reducing power consumption while maintaining ease of operation.
2Ease of operation
If the display remains on during pen pauses, then operation continuity is maintained, but power consumption increases
Solution Approach 1:
The system continuously monitors feedback from the electronic pen's state (detected through coordinate changes, time duration, and slope information) to automatically control the display state. When the pen is detected to be stationary for a predetermined time, the system provides feedback to turn off the display, thereby reducing power consumption while maintaining operational continuity through automatic resumption when the pen is picked up again.
3Ease of operation
If manual operations are required to turn the display on and off, then user control is precise, but the number of operations increases
Solution Approach 1:
The system performs self-service by automatically detecting the electronic pen's state and controlling the display accordingly. The programming module monitors pen coordinates, time duration, and slope to determine when to turn the display on or off without requiring manual user operations. This self-service mechanism maintains precise control based on actual usage patterns while significantly improving efficiency by eliminating redundant operations.
