Mobile Device Line Selection via Audio Prompts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern mobile devices lack an efficient method to allow users to select and initiate outgoing calls on specific communication lines, which can lead to incorrect billing and tracking issues for business and personal communications.
Innovation Solution
A mobile device method and configuration that includes detecting call initiation, outputting an audio prompt for line selection, receiving user input, and using a communication module to place calls on the selected line, enabling users to choose between multiple communication lines associated with different phone numbers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication lines are associated with a mobile device, then the device can support separate billing and tracking for business and personal communications, but the user cannot easily select which specific line to use for outgoing calls
Solution Approach 1:
The system performs preliminary action by detecting call initiation and automatically presenting line selection options to the user before the call is actually placed. This allows the user to choose the appropriate communication line in advance, resolving the contradiction between supporting multiple lines and maintaining ease of operation.
Solution Approach 2:
An audio prompt serves as an intermediary between the user's call initiation action and the actual call placement. The audio prompt presents line selection options and guides the user through the selection process, enabling multi-line support without complicating the overall operation.
2Ease of operation
If the system automatically selects a default communication line, then call placement is simplified, but the user cannot ensure calls are placed on the intended line for accurate billing
Solution Approach 1:
The system provides feedback to the user by presenting audio prompts that display available communication lines and their associated phone numbers. This feedback mechanism allows users to verify which line will be used before placing the call, ensuring accurate line selection while maintaining automated call placement.
Solution Approach 2:
The system performs preliminary line selection and presents options to the user before the call is actually placed. This preliminary action allows users to confirm or modify the default line selection, ensuring both ease of operation and measurement precision.
3Ease of operation
If the system presents visual line selection options, then users can see available lines, but hands-free operation is limited
Solution Approach 1:
The system replaces the mechanical visual display interface with an acoustic audio prompt interface. This substitution allows users to select communication lines hands-free by listening to and responding to audio prompts, thereby maintaining ease of operation while enabling hands-free capability.
Solution Approach 2:
An audio prompt acts as an intermediary that conveys line selection information acoustically rather than visually. This intermediary enables hands-free operation by allowing users to receive and respond to line selection options through audio output and voice recognition.
