Vehicle Display System for Passenger Conversation Initiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems fail to provide motivation for starting conversations among passengers, particularly in pallet vehicles where riders are strangers, as they do not account for individual conversation intentions or desires.
Innovation Solution
A display system mounted on vehicles that includes input and display devices, as well as sensors, to estimate and display conversation desire or intention levels among passengers, allowing them to know and communicate their own and others' willingness to engage in conversation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional information providing devices are used to identify excitement in conversation, then appropriate keywords can be provided to continue conversation, but motivation to start conversation among strangers is not provided
Solution Approach 1:
The system performs preliminary detection of conversation desire and intention before conversation actually starts. By detecting physiological signals and analyzing speech patterns in advance, the system identifies passengers who are ready to converse, enabling timely provision of conversation topics and eliminating the hesitation to initiate conversation among strangers
Solution Approach 2:
The system continuously monitors conversation desire levels and provides feedback through display devices showing matching passengers and suggested topics. This feedback loop helps passengers understand others' conversation intentions and receive guidance on appropriate conversation initiation, resolving the information loss about conversation intentions
2Ease of operation
If display devices are provided at each passenger place to show conversation desire levels, then conversation motivation is enhanced, but device complexity increases
Solution Approach 1:
The control device serves multiple functions: it detects physiological signals from sensors, analyzes speech patterns, determines conversation desire levels, identifies matching passengers, and controls display devices. By consolidating these functions into a single control unit rather than separate dedicated devices for each function, the system enhances conversation initiation while managing overall device complexity
Solution Approach 2:
The system automatically detects conversation desire through physiological sensors and speech analysis without requiring manual input from passengers. The control device autonomously processes data, determines matching passengers, and provides conversation topics, reducing the operational burden on passengers while maintaining enhanced conversation motivation

AI summary
There is provided, in a vehicle capable of accommodating a plurality of passengers, a display system capable of providing a motivation to start a conversation among the passengers in view of conversation intentions of each passenger. The display system includes a control device, and at least one display device. The control device is configured to perform a conversation desire display process to display a conversation desire level of each of the passengers. Alternatively, the control device is configured to perform a conversation intention display process to display a conversation intention of each of the passengers for the other passengers. The conversation desire level and the conversation intention among passengers are input to the input device provided in the display system, by an operation of the passenger. Alternatively, they are estimated by the control device based on the passenger state information detected by the sensor provided in the display system.
