Drawing Pattern Command Input for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack an efficient and user-friendly method for inputting commands, relying on traditional interfaces that can be cumbersome and limiting in functionality, especially for tasks like search, file management, and device control.
Innovation Solution
A method and mobile terminal design that utilize a touch screen to receive user drawings, matching them against a stored table of patterns to execute corresponding commands, allowing for intuitive input of commands through drawing patterns for search, file management, brightness control, and other functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional input interfaces are used in mobile terminals, then device structure remains simple, but user operation convenience deteriorates and functionality is limited
Solution Approach 1:
The touch screen serves multiple functions: it acts as both a display device and an input device for receiving drawing patterns. The system can recognize various types of drawings (circles, squares, triangles, etc.) and map them to different commands, allowing a single interface to handle diverse input operations without requiring additional physical buttons or controls
Solution Approach 2:
The command input system transitions from static predefined options to dynamic free-form drawing recognition. Users can draw arbitrary patterns on the touch screen, and the system dynamically interprets these patterns to execute corresponding commands, making the interface adaptable to user intentions rather than limiting users to fixed input methods
2Adaptability or versatility
If drawing pattern recognition is implemented on touch screen, then command input versatility improves, but system complexity increases
Solution Approach 1:
The system pre-stores multiple drawing patterns and their corresponding commands in memory before operation. When a user draws on the touch screen, the system compares the drawing against the pre-stored patterns to identify matches and execute the associated commands. This preparation of pattern templates in advance simplifies the real-time processing requirement
Solution Approach 2:
The system creates digital copies of drawing patterns and stores them in a database for comparison. Instead of analyzing every possible drawing from scratch, the system compares user drawings against stored pattern copies, significantly reducing computational complexity while maintaining recognition accuracy
3Adaptability or versatility
If multiple input devices are added to mobile terminal, then command input functionality improves, but device structure becomes complex
Solution Approach 1:
The touch screen is designed to perform multiple functions: displaying information, receiving tactile input, and recognizing drawing patterns for command execution. This multi-functional design eliminates the need for separate physical buttons, dials, or other input devices, maintaining structural simplicity while providing diverse input capabilities
Solution Approach 2:
The display function and input function are merged into a single touch screen component. Rather than having separate display and input devices, the system combines these functions, allowing the same surface to both present information and capture user commands through drawing gestures

AI summary
The present disclosure is related to a method of inputting a command in a mobile terminal comprising; storing a table including at least one drawing pattern and a command on the each drawing pattern; receiving a user drawing on a touch screen; and determining a drawing pattern matching with the user drawing pattern by comparing the user drawing pattern and the table to execute a command corresponding the determined drawing pattern, and a mobile terminal using the same.
