Meetrip

Background

We are working on a metaverse platform where people can share not only their own travel experiences such as photo or text, but also their biometric data.

And the name of the project? Since we want everyone's special experiences to "meet" in the metaverse world, we decided to call our project "Meetrip", by mixing those two words.

What Can Meetrip Do?

Meetrip is basically a metaverse photo gallery for you.

This is a simple sketch of actual metaverse we're thinking.

You can exhibit your own photos in the metaverse space that everyone can see and appreciate.

And what's more cool is that you can also exhibit biometric data measured by smart band linked to smartphone with photos you took on the smartphone.

This biometric data can be used to tell your friends how entertaining your trip was.

Or, If you feel uncomfortable to show your data, you can just post a one-line comment. We respect that. We'll tell you more about this later.

And here is how it works.

Service Model

This is our service model.

• User

Let's start with the User section. As you can see in the picture, we collect biometric data, GPS trails, photos, etc., of a user wearing or holding IoT devices.

• IoT Platform

We used the IoT platform to send sensor data collected from IoT devices to the metaverse server. As an IoT client platform, a smartphone application modeled as ADN-AE is implemented. Mobius, modeled as IN-CSE, is used as an IoT server platform.

The data structure can be shown with the resource tree below. We classified the container according to the type of data(on the very right side). And those containers are also classified by user IDs.

• Storage Server

In the Storage Server section below, photos are uploaded to Firebase.

IoT servers can also receive photo data, but it is not a good choice considering transmission time and storage space.

• Metaverse

Metaverse provides a personal gallery for you.

The gallery is an environment where many people can gather to see your photos and communicate. Detailed informations are in our demo video.

System Architecture

The following represents our system model.

It shows which flow of the sensor data generated from smart bands and smartphones is connected to the Metaverse world.

• Several kinds of biometric data measured by the smart band are sent to smartphone.
• Then, they are transmitted to the Mobius server along with data such as the location, weather, and image path data generated by the smartphone.
• On &Cube inside our application implemented as ADN-AE, we set the user protocol to HTTP.
• If you take a photo on your smartphone, it saves the image path data to be sent to Mobius and uploads the photo to Firebase Storage.
• Through Subscription/Notification, the data will be transferred to the Metaverse section.
• Based on the data received, we will request photo and biometric data from Firebase and display those in the metaverse environment.

Android Application

This is the UI configuration of the Android application. If you modify the photographing part, the development of the application is completed.

Security

Like we told you, you can feel just "not right" about showing your personal biometric data or location to public.

That is a reasonable feeling. Those are surely PRIVATE!

We have followed Mobius's default configurations since this is a simple sketch and no outsider's personal data was used.

But if we make this as an actual public service, we'll have to change access control policy.
