Mobile Line Selection Menu and Call Log
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with multi-line capabilities often lack a user-friendly interface for selecting the appropriate communication line for outgoing calls, leading to confusion and inefficient tracking of calling activities across different lines.
Innovation Solution
A dynamic user interface is provided on mobile devices that displays a call screen with a line selection menu, allowing users to select from multiple communication lines for outgoing calls, and includes a call log feature for tracking call activities by line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication lines are supported on a mobile device, then line-specific tracking and billing capability is improved, but user interface complexity and ease of operation deteriorates
Solution Approach 1:
The system pre-loads and displays all available communication lines in the line selection menu before the user needs to make a selection. This preliminary preparation eliminates the need for users to navigate through multiple screens or settings to access alternate lines, thereby maintaining ease of operation while supporting multiple communication lines.
Solution Approach 2:
The line selection menu is integrated into the existing call interface, making the same interface serve dual purposes: displaying outgoing call information and providing access to multiple communication lines. This universal approach allows the system to support multi-line functionality without adding separate, complex interfaces.
2Ease of operation
If a line selection menu is displayed on the call screen, then ease of operation for line selection is improved, but device complexity increases
Solution Approach 1:
The line selection menu is merged with the existing call screen interface rather than being a separate entity. The menu integrates seamlessly with outgoing call information display, allowing users to select lines without transitioning to a different screen or mode. This merging approach improves ease of operation while avoiding the complexity of maintaining separate interfaces.
Solution Approach 2:
The interface dynamically adapts its display based on user interaction state. The line selection menu appears or changes based on whether the user is initiating a call or viewing call information, allowing the interface to remain simple for basic operations while providing advanced functionality when needed.
3Measurement precision
If call log tracks all lines separately, then measurement precision for line-specific tracking is improved, but loss of time for managing call logs increases
Solution Approach 1:
The call log is segmented by communication line, with each line having its own separate tracking records. This segmentation allows precise measurement and tracking of call activities for each line independently, while the automated organization eliminates manual sorting time, thus reducing the loss of time for managing call logs.
Solution Approach 2:
The system automatically updates and organizes call log entries with line identification information as calls are made or received. This real-time feedback mechanism ensures accurate tracking without requiring users to manually record or categorize calls, thereby maintaining measurement precision while minimizing time investment.
Data Source
AI summary
A system and method for providing a user interface that allows users to change the active line on which an outgoing call may be placed. In example embodiments, upon detecting call screen interaction a line selection menu is displayed. The line selection menu contains a plurality of line identifiers, each line identifier uniquely identifying a corresponding one of the multiple communication lines accessible at the mobile device. A system and method is also presented for providing a call log for identifying call activity associated with a plurality of communication lines.
