Video: Surprise

You’re planning the perfect evening. A lovely dinner for two, cooked by yourself. That’s always a good way to impress someone special. Stimulating those taste buds with the meal you’ve prepared and the harmoniously matching wine you’ve chosen. Candles, music…it doesn’t get more romantic than that. Or does it? Wait for the surprise…


Video: Breaking New Ground

Time to get our hands dirty! hybris Labs isn’t just about building innovative prototypes that are designed to enhance the in-store shopping experience for consumers. We also think about how to improve B2B processes.

In B2B, time is of the essence. And when products are needed, but have to be reordered to keep things going, time is actually money. We thought of a way to minimise the factor time by simplifying the entire equation.

The first step is to set up a geo-fence, to define a list of the products in use. This will reduce the time needed for an on-site worker to find the right product, or might even exclude items that are not meant to be ordered from a specific location. Next, an ultrasound signal has to be assigned to each of these products. A determined ultrasound library recognises these signals, and adds the required items to a picklist. The order can now be placed and only needs approval from a supervisor or manager. Customer service will automatically be requested, just in case any kind of problems should occur. In addition to that, we’ve integrated conference call features and  push notifications for certain procedures.

This looks cooler than it might sound, so see for yourselves! hybris Labs, moving mountains…

Coupon Boxes – small, simple & orange

We’ve had them for a while and have been demoing them regularly at events, but never got round to present them here. That’s not really fair though. Okay, they’re probably not as controversial as Google Glass and not as magical as Stream… but they’re orange, they flash (a bit) and we like ‘em.

Right, let’s be a bit more serious. Our Coupon Boxes are a great way of handing out vouchers to customers. They can be placed basically anywhere. The customer just needs to tap the box with his phone to receive the coupon, a signed URL, which is transmitted via NFC. Adopting the coupon to gender is also possible, if a facebook profile is detected.

So where’s the extra benefit in handing out vouchers this way? Well, for a start it can be interesting to know where a coupon was picked up. Taking a more active approach, Coupon boxes can be used to guide customers to specific places, adding an element of gamification to the shopping experience.

Again, both sides can profit: customers receive a voucher, retailers gain a bit of information and everybody’s happy.


The Smart Wine Shelf – how IoT and retail come together

We’re close to present a new #hybrislabs prototype to the world, this time around IoT and Retail. Now that the technical design is pretty much nailed down, implemented and to a large degree well tested, I figured it’s the right time to write a blog post about it. We will first show this new prototype at the hybris North America Customer Days 2014 in Chicago early May.

You’ve seen me writing and presenting around IoT before and the smart wine shelf is really the project I used to explore and learn most around IoT. So what is the smart wine shelf? Well, a wine shelf (to some degree), connected to the Internet. Here’s a picture:



Why would you connect a wine shelf (aka an “element in a retail space”, hey commerce!) to the internet? Two reasons:

  • customer experience and
  • analytics

Our wine shelf improves the customer experience, as it will show you what wine fits your taste. We’ve created a mobile app which allows customers to walk through a quick wine test, then send the wine profile down to the shelf. The right selection of wine, according to your profile, lights up. Whenever to pick a bottle – either with a previously sent profile or not – you see details about the wine, it’s winery, which food it goes with. If the shelf has a profile, it will also show you why this wine fits: because it fit’s your overall style, acidity profile, etc.




And for analytics – whenever a customer lifts a bottle, either with a previously performed wine test or not, we send that data to the cloud where we analyze it. This analysis is used for two displays, as you can see in the picture. The first display is presenting the analytics dashboard of the wine shelf. It would normally not be close to the shelf ifself, we just put it there for demonstration purposes. The second display will provide details about the wine that is taken out of the wine shelf.




Making our life easier

While this is a great prototype, we needed to make our life a bit easier here and there to actually be able to create it. This is one general thing I learned during the last years and while we’ve been creating more and more prototypes. You concentrate on the main task and simplify the rest. The main task is: figuring out IoT. This means how is hardware connected in the best possible way – stable, fast and secure. We neither want to create the perfect shelf it self (e.g. space for multiple bottles each) nor the perfect “physcial selection mechanism” (we might have better placed the light rings above the wine bottles – but it needs to be portable and all components go into one platform for a bottle). Also using switches for input was mainly chosen because it provides a stable and easy input mechanism. There are other ways: ultrasonic distance sensors, pressure sensors, you name it. That’s not the point here.

Be your own customer

Being myself an absolute idiot when it comes to wine, I’d honestly believe this shelf would provide myself a lot of value (what is your experience with wine?). The real power of this can be realized when you stop thinking about the specific implementation of this prototype – the wine shelf. What if every retail space could become smart? What if you could use these to see which foods you can eat based on allergies that you have? What if the data gathered from these retail elements could be used to provide realtime information for in-store advertising?

The technical stuff

Let’s investigate a bit how the shelf was actually put together and which components have to work together. The following diagram is meant to help guide us:

Technical Wine Shelf - Firmata

  • iBeacon & smartphone app: A smartphone app is used for the wine test. The app then allows the customer to send her wine profile to a cloud API for all wine shelves. Part of that HTTP call is the id of the wine shelf, which we resolve via iBeacon proximity sensing.
  • All logic resides in the cloud and is accessed via a RESTful API: Once a profile was received and no one else currently uses the shelf to explore his wine taste, the logic (written in node.js) will match the customer profile against the wines in the database. If there are matches, it will look up the wine shelf and determine which positions in the wine shelf need to be highlighted. It will then use a ZMQ publishing queue under the topic name of the wine shelf to send the highlighting data to the shelf.
  • A Raspberry PI and an Arduino are the physcial, non-cloud elements that make the shelf smart: The Raspberry PI acts as subscriber to the cloud which publishes the selections. It was chosen mainly due to (network/internet)  stability reasons. We’ve explored Spark Core, Electric Imp and a few other options (like Espruino with a CC3000 module, Arduino with Ethernet Shield), but none was stable of fast enough to get the job done (this is changing quickly, but at the time we based a decision this was the case). The Raspberry PI’s main job is to act as a broker of data between the hardware and software world. It interfaces the Arduino, which is a well-known prototyping board. The Arduino handles the “last mile”, or “last centimeters” which is the actual control of the lights (output for selection)  and switches (input for analytics). Raspberry PI and Arduino also have to understand each other – we’ve used the so-called Firmata protocol to let them both talk to each other. It’s a blazingly fast serial protocol and allows us to connect the Arduino to the Raspberry PI via a single serial USB connection.
  • Switches and NeoPixel rings: these are very basic electronic components for the input and output of the shelf. There is almost no drama here, but I tell you that soldering 16 NeoPixel rings which each have 4 pins to solder plus the switches created a mild headache for a few days. The pic below also shows these 16 platfors, each housing a NeoPixel ring and switch for one bottle in the shelf.


Because we both send data down from the cloud to the hardware and collect data from the hardware and send it up to the cloud, our wine shelf is really an excellent example for my current valid defintion of IoT: a thing connected, able to receive and send messages from/to the cloud, able to process data and able to gather input and perform output.

You need a team for this

This is where I am really proud of #hybrislabs. A project like this requires so many diverse skills, no single person can get that done in a reasonable amount of time without going crazy. We’ve truely worked as a multidisciplinary team and many people with very different skills (mainly from software) have contributed to make that happen. Thx to Bert for the great iOS app, thx to Scott for figuring out the perfect bottles on top of the platforms, thx to Elke for designing the physical shelf, thx to Uwe for iteratively working with me on the platforms that house the switches and NeoPixel light rings and of course thx to Nick for already creating a script for a soon to be produced lab video, collecting and curating all data used (wine data, profile, matching, etc.) and discussing a lot with me about how to best build the shelf. Of course thx to Paul for many discussions and also letting us do this.

Global Making

I mentioned the hybris NA Customer Days 2014, where this will be shown for the first time. I happen to be in Munich, Germany and the event is in Chicago, USA. This means on top of all this, we’re also producing the wine shelf in the US while I will bring the platforms that house the components, cables, computers the day before the event. This is also the reason, you see so many connectors between these component platforms: It all needs to be disassembled, put into my travel bag (airport security will love me) and assembled in Chicago for the event. So a big thx to Tom in the US, too! After the event, we will build the shelf a second time for our permanent lab space in Munich. I expect the second whine shelf to take a fraction of the time needed for the first.

Like always, let’s discuss IoT in the hybris Google+ Community!
