In-Vehicle Information Addition System for Safe Hands-Free Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication systems do not effectively associate and display additional information with personal communication data in a manner that is safe and convenient for users, particularly in vehicle environments, where accessing additional information requires manual interaction with the device, compromising safety.
Innovation Solution
An information addition system that integrates with a mobile communication terminal, hands-free apparatus, and navigation system to associate communication partner information with additional data such as date, time, and voice memo information, allowing for voice output or display of this information in various modes and timings, ensuring safety during vehicle use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional information is stored only in the mobile telephone, then the mobile telephone can display the information, but the user cannot access the information safely while driving
Solution Approach 1:
The patent combines the mobile telephone with the in-vehicle device (hands-free apparatus) to form an integrated system. The mobile telephone stores additional information, while the in-vehicle device provides voice output and display capabilities, allowing users to access information safely through voice commands and auditory feedback while driving.
Solution Approach 2:
The in-vehicle device acts as an intermediary between the mobile telephone and the user. It receives data from the mobile telephone, processes it through voice recognition, and provides output through speakers and display, enabling safe information access without requiring manual interaction with the mobile telephone.
2Loss of information
If the mobile telephone displays additional information on its display unit, then the information is visible, but the user must manually operate the device which compromises safety
Solution Approach 1:
The system segments the information access function into two parts: the mobile telephone stores and manages the additional information, while the in-vehicle device handles display and voice output. This segmentation allows the information to be accessible through multiple channels (visual display on in-vehicle device, voice output) without requiring manual operation of the mobile telephone.
Solution Approach 2:
The system adds another dimension of information access by implementing voice recognition and voice output capabilities in the in-vehicle device. Instead of relying solely on visual display and manual input, users can interact with the system through voice commands and receive information through auditory feedback, creating a new dimension of safe information access while driving.
3Adaptability or versatility
If the system integrates multiple devices (mobile telephone, hands-free apparatus, navigation apparatus), then information accessibility improves, but system complexity increases
Solution Approach 1:
The in-vehicle device is designed with multi-functionality, serving as both a hands-free communication apparatus and a navigation device, while also functioning as an information display and voice recognition system. This universality reduces the need for separate dedicated devices for each function, thereby managing system complexity while maintaining high information accessibility.
Data Source
AI summary
An information addition system acquires data and a control signal from a hands-free apparatus and a navigation apparatus. The hands-free apparatus is connected to a mobile communication terminal and includes an address-book data storage unit that associates communication-partner information of the mobile communication terminal with name information and stores the associated information in a personal information database as first personal information. The information addition system includes an additional information acquiring unit that acquires date and time information at an outgoing or incoming call from the navigation apparatus as first additional information and that acquires predetermined information at the outgoing or incoming call as second additional information, and an information adding unit that identifies the first personal information in the personal information database on the basis of the communication-partner information and that associates the first and second additional information with the first personal information and stores the associated additional information.
