Onboard Voice Outputting Device for Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice outputting devices do not adequately protect user privacy by failing to confirm if other users are present before conveying information intended for a specific user, particularly in scenarios like messaging service notifications within vehicles.
Innovation Solution
A system that includes a judging section to determine if the vehicle occupant is alone and an outputting section to only deliver information to a voice outputting device within the vehicle when the occupant is identified and no external exposure is anticipated, using a combination of voice input, image capture, and portable terminal identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is outputted by voice from the voice outputting device without confirming whether other users are present, then information can be conveyed to the user, but privacy protection is compromised
Solution Approach 1:
The judging section performs occupancy judgment before the outputting section conveys information. The system preliminarily determines whether other users are present around the specific user, and only proceeds with voice output if the judgment confirms it is safe to do so, thereby preventing privacy exposure before it can occur
Solution Approach 2:
The judging section acts as an intermediary between the information source and the voice outputting device. It mediates the information flow by controlling whether information should be output based on occupancy judgment, serving as a gatekeeper that balances information conveyance with privacy protection
2Measurement precision
If the system uses multiple identification methods (voice, image, portable terminal) to identify occupants, then identification accuracy improves, but device complexity increases
Solution Approach 1:
The voice outputting device is designed with multi-functionality, integrating voice input capability, image capture capability, and portable terminal identification capability into a single device. This allows the system to use multiple identification methods without requiring separate dedicated devices for each function, thereby improving identification accuracy while limiting the increase in overall system complexity

AI summary
An onboard voice outputting device includes: a judging section that judges whether or not an occupant of a vehicle is alone; and an outputting section that, in a case in which it is judged by the judging section that the occupant of the vehicle is alone, outputs information, which is an object of outputting, to a voice outputting section that is installed in the vehicle and that outputs information by voice into a vehicle cabin.
