Stylus Pull-Out Length and Rotation Menu Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable devices with stylus units lack intuitive and convenient methods for controlling menu interfaces when the stylus is separated from the device, requiring separate operations for menu selection and execution.
Innovation Solution
A portable device equipped with a stylus unit, sensor unit, and processor that navigates and selects menus based on the rotation angle and length of the stylus pulled out, providing a menu interface that allows users to select or execute menus without additional input operations.

Engineering Contradiction Analysis
1Weight of moving object
If the stylus unit is separated from the device for portability, then portability is improved, but the convenience of setting input environment deteriorates
Solution Approach 1:
The stylus unit automatically performs setup functions by itself. When pulled out to a specific length, the sensor detects this state and automatically triggers the input environment setup process without requiring separate user operations. The stylus unit serves both as a writing tool and a control mechanism for configuring its own usage environment.
Solution Approach 2:
The system uses the pulled-out length of the stylus unit as a controllable parameter to determine different operational modes. By detecting specific length thresholds, the system automatically switches between different menu interfaces and input environments, allowing the same physical action (pulling out the stylus) to trigger different functional states.
2Measurement precision
If separate touch input operations are required for menu selection, then input precision is improved, but operation complexity increases
Solution Approach 1:
The patent combines multiple functions into the stylus unit itself. The stylus serves as both the input tool for precise selection and the control mechanism for menu navigation. By integrating the selection function into the pull-out action, the system eliminates the need for separate touch operations while maintaining input precision through the sensor's ability to detect specific pull-out lengths and rotation angles.
Solution Approach 2:
The stylus unit is designed to perform multiple functions: writing input, menu navigation, and environment configuration. A single pull-out and rotation operation can navigate menus and select options, making the stylus a universal control device that replaces multiple separate input mechanisms.
3Measurement precision
If separate input operations are required for menu execution, then control accuracy is improved, but time efficiency deteriorates
Solution Approach 1:
The system navigates to the target menu option in advance during the pull-out process. As the user pulls out the stylus to the desired length, the system automatically navigates through the menu hierarchy and positions the cursor at the appropriate selection. When the stylus reaches the final pull-out length, the pre-navigated menu item is automatically selected and executed, eliminating the need for additional confirmation operations.
4Measurement precision
If the stylus unit is used for delicate touch input, then input precision is improved, but the ease of setting input environment deteriorates
Solution Approach 1:
The stylus unit automatically configures its own input environment based on its pull-out length. When pulled out to a specific length, the sensor detects this state and automatically sets up the appropriate input parameters and menu interface, eliminating the need for users to manually configure settings while using the precise stylus input tool.
