Voice-Controlled Moving Body Operation Support System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic driving systems face challenges in safely executing user instructions, particularly when the instructions are unclear, unsafe, or mismatched with the moving body's current state, leading to potential accidents or inappropriate service provision.
Innovation Solution
A moving body operation support system that includes an acquirer, microphone, transceiver, and processor, which switches between two operations based on user instruction and moving body information to ensure safe operation. In the first operation, the system executes user instructions if safe, while in the second operation, it enables communication with an operator to confirm and adjust the user's intentions, ensuring safe navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system automatically executes user instructions in automatic driving mode, then productivity and ease of operation are improved, but reliability deteriorates when instructions are unclear or unsafe
Solution Approach 1:
The system implements feedback by having the notification device inform users of executed instructions and by providing a communication interface where users can report issues. This feedback loop allows the system to learn from user responses and improve the safety of automatic instruction execution over time.
Solution Approach 2:
The notification device and communication interface act as intermediaries between the automatic driving system and the user. When an instruction is executed, the system uses these intermediaries to inform the user and provide a channel for user feedback, bridging the gap between automatic operation and human oversight.
2Reliability
If the system switches to communication mode to confirm user intentions, then reliability is improved, but productivity and ease of operation deteriorate due to additional communication steps
Solution Approach 1:
The system applies partial action by selectively switching to communication mode only when necessary - specifically when there is a mismatch between the recognized instruction and the executed operation. For routine, clear instructions, the system executes automatically without additional communication steps, thus maintaining productivity while ensuring reliability when needed.
3Reliability
If the system provides detailed notification of executed instructions, then reliability and user awareness are improved, but device complexity increases
Solution Approach 1:
The notification device serves multiple functions: it notifies users of executed instructions, provides a communication interface for user feedback, and potentially logs system operations. By making this single device multi-functional, the system avoids adding separate complex subsystems while still achieving comprehensive user awareness and reliability.

AI summary
According to one embodiment, a moving body operation support system includes an acquirer, a microphone, a transceiver, and a processor. The acquirer acquires moving body information relating to a state of a moving body. The microphone is provided in the moving body. The transceiver performs transmitting to and receiving from an operator communication device. The processor implements one of a first operation or a second operation based on the moving body information and instruction information. The instruction information relates to an instruction based on a sound acquired by the microphone. The instruction is of a user riding in the moving body. In the first operation, the processor causes the moving body to perform an operation corresponding to the instruction information. In the second operation, the processor enables communication between the user and the operator by the transmitting and receiving between the transceiver and the operator communication device.
