Dynamic Virtual Keypad for Message Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartphone keyboards are inconvenient for typing due to a fixed keypad layout, making it difficult to perform message transmission functions efficiently, especially when a transmission button is located at a specific position, requiring users to move their hands significantly to press it.
Innovation Solution
An apparatus and method that display a message input screen with a virtual keypad, where selecting a character key and holding another key in a preset color for a specific time performs a preset function, such as line break or text message transmission, enhancing keyboard input efficiency and user convenience by eliminating the need to move hands to a fixed transmission button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed keypad layout is used with a transmission button at a specific position, then the device structure is simple and reliable, but user convenience deteriorates due to the need to move hands significantly to press the transmission button
Solution Approach 1:
The patent implements a dynamic virtual keypad where the transmission button position changes based on the currently selected character key. Instead of a fixed layout, the transmission button is positioned adjacent to the active character key, allowing the layout to adapt dynamically to user input needs and eliminate hand movement.
Solution Approach 2:
The transmission button is positioned locally adjacent to each character key rather than at a distant fixed position. This local positioning ensures that the transmission function is always accessible near the current input location, improving ease of operation without requiring global layout changes.
2Productivity
If a fixed transmission button position is used, then the device complexity is low, but productivity deteriorates due to inefficient message transmission operations
Solution Approach 1:
The virtual keypad implements dynamic repositioning of the transmission button based on the selected character key. This dynamic adjustment eliminates the need for users to move their hands across the keyboard, significantly improving message transmission efficiency while maintaining relatively simple software-based control.
Solution Approach 2:
The transmission button is pre-positioned adjacent to each character key before selection occurs. When a user selects a character key, the transmission button is already in the optimal position for immediate transmission, eliminating delays and improving operational productivity.
3Ease of operation
If character keys are indicated in a preset different color after selection, then ease of operation is improved by showing adjacent keys, but device complexity increases due to additional display control
Solution Approach 1:
The patent uses color changes to indicate selected character keys and their adjacent keys. When a character key is selected, it and its neighboring keys are highlighted with a preset different color, providing visual guidance to users about available transmission options. This color-based indication system improves ease of operation through intuitive visual feedback while implementing relatively simple display control logic.

AI summary
Disclosed are an apparatus for transmitting a message and a method thereof that perform a preset message transmission function or a preset line break function by selecting a character key on a message input screen displayed on the apparatus for transmitting a message and then pressing another character key displayed in a preset color around the selected character key for a preset time or longer so that the efficiency of keyboard input is enhanced and the convenience of a user inputting text is improved.
