Voice-Activated Call Pick-Up for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for mobile device call pick-up while driving require users to interact with the device, posing safety risks due to the need for hands-free operation.
Innovation Solution
A method utilizing sensors to detect when a mobile device is within a vehicle and in motion, allowing voice-activated call pick-up by automatically activating the microphone and connecting incoming calls via voice commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user interacts with the mobile device to pick up a call, then the call can be connected, but the user's safety is compromised when driving
Solution Approach 1:
The patent replaces mechanical interaction (pressing buttons, touching the screen) with voice-based acoustic interaction. The system activates the microphone to capture voice commands, processes them through speech recognition, and executes call actions without requiring physical contact with the device, thereby eliminating the safety risk of hand-device interaction while maintaining call connection capability
Solution Approach 2:
The system enables the mobile device to automatically detect and respond to call pickup commands through voice activation. The device monitors for specific voice patterns, automatically initiates call connection procedures, and manages the calling state without requiring manual intervention, allowing the driver to maintain focus on the road while the device handles call management autonomously
2Ease of operation
If a headset or speakerphone function is used, then the user does not have to hold the mobile device, but the user still has to interact with the device to pick up the call
Solution Approach 1:
The system performs preliminary actions by proactively monitoring for voice commands and pre-processing potential call pickup intents before the user needs to take action. The microphone remains active and ready to capture commands, and the system pre-configures the call connection parameters, so when a voice command is detected, the call can be connected immediately without requiring the user to navigate through device menus or press multiple buttons
3Reliability
If a button press is required to pick up the call, then the call can be connected, but unsafe driving conditions are created
Solution Approach 1:
The patent systematically replaces all mechanical button-pressing operations with acoustic voice command recognition. The microphone captures voice inputs, the speech recognition system interprets commands such as 'pick up call' or 'answer', and the system executes the call connection accordingly. This substitution eliminates the need for any manual button interaction, allowing drivers to keep both hands on the wheel and eyes on the road while maintaining reliable call pickup functionality

AI summary
Disclosed embodiments are directed an application program configured to run on a user's mobile device can allow voice-activated call pick-up to the user, without the user having to use his or her hands for picking up the call. For example, the application program can initially be trained to a user's voice command. When an incoming call is received at the mobile device, the user can pick up the call by issuing a voice command. In some embodiments, the application program can determine whether to allow voice-activated pick-up of calls based on data collected from multiple sensors associated with the vehicle, the mobile device, or a remote source.
