Connected to share is how our lives are changing daily. The technologies are supporting us with the day-to-day work and helping us with the challenges we are facing. The most important goal is to keep them human-centric. The future is there. And this time has already begun.

Two years ago our team was united around the idea of building solutions based on Internet of Things. This is how GRIMIK was born. In the beginning, understanding each other was, let's say, funny story: one marketing expert, one hardware engineer and one software developer speaking very different languages although we were using Bulgarian to communicate. But we shared the same vision for contributing to achieve sustainable and integrated tomorrow.

The main idea of our work was to build device for real-life social connection based on personal interest or current intent at specific moment. Having privacy in mind at first place we choose approach to track the data but not the people.

Today we are part of the #EUvsVirus hackaton with the goal to provide solution helping to safe our main rights of personal freedom and the power of living "United in diversity".

What it does

The wearable IoT device of GRIMIK is using Bluetooth to broadcast and receive UID data. The statistics are not related to the user or his location. The app on the phone is sending the information only about other GRIMIK gears nearby. Using cluster approach the interaction between the owners can be traced on approximately base.

In terms of pandemic and using mathematical approach critical issue can be addressed such as a "permanent observatory" to collect data on the behaviour and the habits of the population, in order to place preventive measures to reduce the risk of a new emergency.

Also tracking the possible epidemic expansion and analyse where and which measures to be taken.

Notification to every single user can be send to indicate personal health levels risk based on his social interactions.

The devices can be considered also as an everyday gadget. Building a profile of interest from various fields can assist the users to build real-life relationships. The indicators can guide them to find a partner, a friend or people sharing the same values.

How we built it

To protect user's privacy we decided to apply approach where we use the devices themselves as UID in our database. This is the first layer of security. The second is running an algorithm for one dynamic change of the IDs over the time.

The device is build of 3 main segments:

  • core, where the CPU and the Bluetooth LTE are placed
  • motherboard, to expand the connection of the core with power supplies and light indicators
  • units, including battery, switch and lights

The user can install the app on Android and iOS devices.

The server is running on .net and use iLCD (intrinsic, Longitudinal Community Detection) algorithm to detect dynamic communities in temporal network, i.e communities which change in a realistic manner when the network evolves.

Challenges we ran into

On 24th of April, we just received the circuit motherboards 2.0 version manufactured based on our schematise. And we don't see this as a coincidence.

Reducing the size of the first prototype was combined with thinking ahead for options to allow integrations of the device with other wearables.

The IoT connectivity is providing wide range of options. Choosing the focus of functional point and providing added value for the user is important decision. It's reflecting on the design of the product and also on the process flow.

This is why today we see the opportunity to help our community and the people around the world facing pandemic challenges.

Accomplishments that we are proud of and what we learned

Building shared vision as a team and achieving to deliver working prototypes was our first milestone. Working with a new type of hardware, writing the software for the system and placing process solutions are our team accomplishments and they reflect currently on the device.

What's next for GRIMIK

We are dedicated finding a way to increase the number of prototypes and run number of tests in the context of pandemic and in our regular life.
