Rendezvous Assistance System Gesture Recognition Crowded Meeting Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle rendezvous systems struggle to achieve smooth rendezvous between a dispatched vehicle and a user, especially when there are numerous persons at the meeting point, making it difficult for the vehicle to identify the correct user.
Innovation Solution
A rendezvous assistance system that includes a mobile terminal carried by the user and a rendezvous assistance device communicating with the mobile terminal. The system generates a message requesting the user to perform a specific gesture, which is transmitted to the mobile terminal at the appropriate timing when the vehicle is near the meeting point, allowing the vehicle to identify the user through the gesture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a meeting point is displayed on a map for rendezvous assistance, then the vehicle can recognize the meeting point location, but the vehicle cannot identify the correct user when there are numerous persons at the meeting point
Solution Approach 1:
The patent introduces a gesture recognition system as an intermediary mechanism between the vehicle and the user. The system transmits a predetermined gesture from the vehicle to the user, and the user performs this gesture at the meeting point. The vehicle then captures images of persons at the meeting point and identifies the correct user by detecting who performed the specified gesture. This intermediary gesture-based communication resolves the ambiguity of user identification in crowded settings.
2Reliability
If the vehicle waits for the user to be visually identified at the meeting point, then the vehicle can confirm the user's presence, but the rendezvous process becomes inefficient when there are many persons
Solution Approach 1:
The patent implements preliminary action by having the vehicle transmit the predetermined gesture to the user before the vehicle arrives at the meeting point. The user is instructed in advance to perform this specific gesture when meeting the vehicle. This pre-established communication protocol enables rapid and accurate user identification upon arrival, eliminating the need for time-consuming visual searching and confirmation processes at the meeting point.

AI summary
The purpose of the present disclosure is to achieve smooth rendezvous of a vehicle and a user even if there are numerous persons at a meeting point. A rendezvous assistance system includes a mobile terminal carried by a user who wants to rendezvous with a dispatched vehicle, and a rendezvous assistance device that assists rendezvous of the dispatched vehicle and the user at a meeting point. The rendezvous assistance device includes a message generator that generates a message that requests the user to do a gesture, a vehicle controller that determines timing of transmission of the message, and a vehicle communicator that transmits a message to the mobile terminal. The mobile terminal includes a mobile communicator that receives a message from the rendezvous assistance device and a notification unit that notifies the user of a request to do a gesture in accordance with the message.
