Mobile Device Voice Control via Call Timing Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in accessing information from a mobile device when it is left at a distant location, especially without internet connectivity, and borrowing another device can lead to social awkwardness and security risks.
Innovation Solution
A mobile device is programmed to recognize a predetermined pattern of call durations and intervals, allowing it to answer and respond via voice commands, enabling users to access contact information over a traditional voice line without revealing personal data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a user borrows another mobile device to access contact information, then the user can obtain the information, but the user risks identity theft and social awkwardness due to retaining personal data on the borrowed device
Solution Approach 1:
The patent introduces a voice communication channel as an intermediary medium between the user and the mobile device. The user calls their own device and provides voice commands, which are processed through the voice line without requiring physical access to the device or borrowing another device. This intermediary channel eliminates the security risks of borrowing devices while maintaining information access.
Solution Approach 2:
The patent replaces the mechanical/physical interaction of borrowing and using another device with a voice-based communication system. Instead of physically handling another device and risking data exposure, the user communicates through voice commands over a telephone line, substituting physical interaction with acoustic signal processing.
2Ease of operation
If the mobile device answers all incoming calls automatically, then the user can easily access the device, but the device cannot distinguish between authorized users and strangers
Solution Approach 1:
The patent employs periodic calling with specific temporal patterns as an authentication mechanism. The system analyzes the timing and frequency of incoming calls to distinguish between authorized users (who know the specific calling pattern) and strangers (who would call at random intervals). This periodic action creates a reliable authentication method while maintaining ease of access for authorized users.
Solution Approach 2:
The patent changes the parameter of call timing from random to predetermined patterns. By establishing specific temporal parameters for authorized calling (intervals, durations, sequences), the system creates a reliable distinction between authorized and unauthorized access attempts, solving the authentication problem while keeping the interface simple for legitimate users.
3Adaptability or versatility
If the user needs to access information without internet connectivity, then the user can use traditional voice lines, but the user cannot access cloud-based or internet-hosted data
Solution Approach 1:
The patent enables the mobile device to serve itself by processing voice commands locally and accessing locally stored information such as contact books. The device does not need external internet connectivity or cloud services to fulfill user requests - it independently processes the voice input, retrieves the requested information from its own storage, and provides the response through the voice line, making the system self-sufficient and adaptable to offline conditions.
Data Source
AI summary
The user calls to the mobile device with a predetermined pattern. In one embodiment the predetermined pattern is coded on the duration of the unanswered calls and the duration between successive calls. The predetermined pattern may be time coded on the durations of successive calls. After detecting the predetermined pattern the mobile device answers the incoming call. The user may continue by identifying via the voice line, if that is required. The mobile device responds to commands provided via the voice line, for example by providing contact information as synthesized speech.
