Wireless Stylus Input Device for Mobile Terminal Application Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile input devices for mobile terminals, such as keypads and touch screens, are cumbersome for users due to their small size and complex character input systems, making it difficult for unskilled users to select and execute application programs and input information efficiently.
Innovation Solution
A mobile input device that uses a pen-like structure with wireless communication capabilities, allowing users to select application programs by rotating a pen body with marked icons and transmit execution instructions, enabling convenient application-specific input of information through local area wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a virtual soft keypad is displayed on a touch screen and selected using a stylus with touch method, then data input function is provided, but the operation process becomes lengthy and complex requiring multiple steps to select application program and input information
Solution Approach 1:
The patent extracts the application program selection and execution instruction functions from the mobile terminal's touch screen interface and relocates them to the stylus device itself. The stylus includes a selection unit with icons representing different application programs and an execution instruction unit, allowing users to select programs and execute them directly from the stylus without navigating through the terminal's menu system.
Solution Approach 2:
The stylus is transformed from a simple pointing tool into a multi-functional device that combines application program selection, execution instruction transmission, and information input capabilities. The selection unit provides multiple application program options, the execution instruction unit triggers program execution, and the stylus tip enables direct information input, consolidating multiple functions into a single universal input device.
2Ease of operation
If conventional keypads or touch screens are used for data input, then basic input function is provided, but the device size becomes small and the character input system becomes complicated making it difficult for unskilled users
Solution Approach 1:
The patent replaces complex virtual keyboard interfaces displayed on the touch screen with physical icon representations on the stylus. Each icon on the selection unit corresponds to a specific application program, providing a simplified visual copy of the program selection interface that is easier to recognize and select, especially for unskilled users who may struggle with small touch screen keys or complex input methods.
3Productivity
If multiple steps are required to execute an application program through menu selection, then application program can be executed, but the operation process becomes lengthy reducing input efficiency
Solution Approach 1:
The patent implements preliminary action by pre-configuring the stylus with a selection unit that contains icons representing multiple application programs. Users can pre-select their desired application program by aligning the indicator with the corresponding icon before approaching the mobile terminal. This preliminary selection eliminates the need to navigate through menu hierarchies at the terminal, allowing direct execution of the pre-selected program upon contact with the touch screen.
