Mobile Terminal Message Input Error Prevention via Event Window
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication terminals often experience message input errors due to other events like call reception or message alerts, as users may inadvertently input keys meant for event recognition rather than message transmission, leading to errors.
Innovation Solution
Inactivating character input keys and displaying an event window when another event occurs during message input, and checking for the ENTER key press to confirm event recognition, allowing the user to close the event window and reactivate input keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a popup window is displayed to notify users of received messages during message input, then users can be informed of important events, but users may inadvertently press keys intended for event acknowledgment rather than message transmission, causing input errors
Solution Approach 1:
The system performs preliminary action by checking whether another event (e.g., received message) occurs before the user finishes inputting the transmitting message. By detecting the event occurrence in advance and displaying an event window, the system prevents potential input errors before they happen, rather than correcting them after the fact.
Solution Approach 2:
The system implements feedback by displaying an event window that notifies users of received messages during the message input process. This visual feedback mechanism informs users of the conflicting event, allowing them to consciously decide whether to acknowledge the event or continue message input, thereby preventing inadvertent key presses.
2Loss of information
If the system checks for predetermined keys to identify event acknowledgment, then event notifications can be processed, but legitimate message transmission keys may be misinterpreted as event acknowledgment keys, leading to message input errors
Solution Approach 1:
The system applies dynamics by changing the functionality of keys based on the current state. When an event window is displayed, the system dynamically determines whether a pressed key is intended for event acknowledgment or message transmission, rather than using fixed key assignments. This dynamic interpretation prevents misidentification of key presses.
Solution Approach 2:
The system performs preliminary action by checking whether another event occurs before finalizing the key press interpretation. By detecting event occurrence in advance and displaying the event window, the system establishes the context needed to correctly interpret subsequent key presses, preventing erroneous identification of message transmission keys as event acknowledgment keys.
3Productivity
If the system allows continuous message input without interruption, then message transmission efficiency is maintained, but users may not recognize important events like received messages, leading to information loss
Solution Approach 1:
The system introduces an intermediary mechanism (the event window) that mediates between continuous message input and event notification. The event window serves as a temporary overlay that delivers event information without completely blocking message input, allowing users to remain aware of events while maintaining input flow.
Solution Approach 2:
The system implements periodic action by checking for event occurrences at specific intervals during message input (e.g., when keys are pressed). This periodic event checking ensures that important events are noticed without requiring continuous interruption of the message input process, thus maintaining productivity while preventing information loss.
Data Source
AI summary
A method and an apparatus f preventing transmitting message input error in a mobile communication terminal are provided. When another event is generated while the transmitting message is being inputted, character input keys are inactivated and an event window is displayed. It is checked whether an ENTER key is pressed while the event window is displayed. If the ENTER key is pressed, the event window and an icon notifying generation of the event are closed. Accordingly, a user of the mobile communication terminal can recognize the generation of the event and prevent transmitting message input error after identifying the generated event.
