It’s been a while since I wrote about expose, but finally I am sitting at the Munich airport again, which is my favorite time to write blog posts. From a technical point of view, expose is in the final phase of being polished. We’ve worked with the designers at SNK to create great user interfaces, ironed out a few bugs here and there and are currently thinking of two showrooms (Munich and New York) to install this prototype. While these discussions and the details will need a few more weeks, I think technically this prototype is locked-down and done. So it’s time to take a final look at it and wrap it all up.
So again, what is it all about?
There’s two perspectives that we can take. The technical and the business perspective.
From a technical point of view, expose is a Hybris Labs Experiment that combines RFID and IoT technology together YaaS. The location subsystem constantly scans for registered RFID labels and tries to determine the best possible location. The data is analyzed and yields an individual journey per user of the system as well as overall location analytics. The action subsystem allows individual participants of this experiment to interact on a 1:1 basis with the system. Current action stations include the signup station, the bar station, the journey station and the party booth – all four offer personalized interactions based on the customer’s previous behavior.
Business-wise, such a system can for example be used at events and showrooms. Via the technical means described above, we can track the location of RFID labels, which could be attached to a visitor’s event badge. From an event-coordinator’s perspective, real-time analytics where people are, where people are likely to go and what they do (action subsystem) can be offered. While the backend-users of such a system gain insights into their event and the flow of users, there’s something in for the visitors that carry the RFID labels, too. They can interact at various action points on a one-to-one basis. This means the barkeeper will remember your name and favorite drink, the event host might be able recommend people to meet based on your interests or location history, etc.
As I am a technical guy, let’s concentrate on the technical a architecture diagram first- have a look:
From bottom to top, you can see these layers of the expose system:
- The very basis of the system are micro-services powered by YaaS – Hybris as a Service. This prototype uses quite a lot, so after registering a user, we’ve got a new customer account via the customer service, the products at the bar of course are maintained via the product service. A purchase / order results in a cart being checked out for the customer.
- Once again, we’ve extended YaaS with custom micro-services for expose. Our RFID readers send HTTP Post requests in regular 3s intervals and the endpoint for those are part of the expose service – part of the expose package. To be brutally honest with you, at this point the configuration is rather static within this service, but at a later stage we could manage it on a tenant-by-tenant basis via a builder module. Totally accurate though in the above diagram are the user interfaces which are rendered by the expose service.
- We’re now touching the physical world, with RFID readers installed at various locations of a showroom and at the action stations where users can interact on a 1:1 basis. Our default setup will use 5 locations (Impinj Speedway Connect readers) and 4 action points. The latter are Raspberry Pis which my colleague Lars Gregori extended with a custom shield. We attach a small antenna to them so users can put their RFID label on top to have it read. The location readers are constantly sending the scanned RFID labels to our service, where we process the location information with some self-made algorithm and store the data in the YaaS document storage.

The 4 action point UIs – signup, bar, journey and party booth.
An extra paragraph on the party booth
The party booth will be an awesome action point of the expose system and it’s a bit crazy, I agree. I have to think of a nice way of showing you the UI’s, so give me a few days after my current trip to get that done. It shows how we can interact with visitors on a 1:1 basis with the help of YaaS. It will load the data that a visitor left at signup and create a personalized party experience. At the moment, we’ve specified how the party booth will roughly look like and a local artist, Andreas Kraeftner from Munich is working on the physical fabrication. We use metal, glass, wood and it all will be combined with the electronics like Raspberry PIs, LEDs, loudspeakers, a disco ball and a fog machine. The booth will take pictures via a camera connected to the raspberry pi within the booth and it will create an animated GIF in the end that users can post on twitter.
So yes, it’s crazy. And different to many showcases you’ve seen before. It’s okay to be different!
