Building a simple demo tool
So, it is yet again time for a new blog post. This time, I will focus on a tool that I have built to showcase the power of beacons and how they can work with advertising to give users relevant communication as they go along.
I give you, the Unacast demo tool. The goal was really to build a flexible tool to showcase the essence of what Unacast is doing, in a user-friendly way that can be handled by our commercial team and also partners of Unacast that bundle our services.
This was a project that was mainly handled by the engineering team, after experiencing in sales meetings that having a demo or visual presentation would be valuable. There were very few strict requirements, as it is always difficult to convey an idea that you need something, but you are not sure exactly what.
Carving out initial requirements
However, I chiseled out some of the requirements to fulfill, based on my own experiences in sales meetings as well as feedback from “the suits”:
- Flexible setup and configuration to handle different showcases and pitches
- Adding / removing beacons
- Adding / removing categories (i.e. Food&Beverage, etc) and attaching these to beacons
- Adding / removing ads and attaching these to categories
- An application that is installed on the user device that “picks up” beacons
- Creating and populating user profiles based on device id
- Displaying an ad on the user device and changing it in real time, based on beacon interactions
- Real-time view of user profile as the device interacts with beacons
- A pleasant UI to visualize the data and provide easy setup
Creating a data model
Based on this, I started iterating on an MVP. The data model and flow were roughly like this:
- An app is the domain or the bucket to which data belongs
- A user is identified by the IDFA of his / her device
- A user interacts with beacons and the app sends info about this to the backend, which saves a new interaction with info about the app, the user and the beacon encountered
- A beacon has one or more tags (Sports, Food, Travel, etc)
- When the user interacts with a beacon, this interaction is saved (as stated above). Also, an advertisement is shown in the app. This advertisement has a tag of the same type as the beacon. So you guessed right, a “sports” beacon will make a “sports” advertisement appear in the user’s app.
- Lastly, when a user opens the app out of range of a beacon, the app shows an ad that matches the tag of the beacon type the user has the most interactions with. If no previous data is available on the user, a random advertisement is served
Getting the hands dirty / Taking a first stab
Much can be said about this stage, but the fact is that pictures are much more telling than words, so I will just say that it ended up something like this:
First, a couple of beacons are needed. These are pretty cool. Stick a couple of USB-beacons in a couple of emergency chargers, and you have a nice setup for testing beacons in a controlled environment.
Users canedit basic information about the demo, such as name, description, beacon UUIDs to use, as well as the page that the app should embed (the app is very simple, just displaying the contents of a user-specified URL with an ad on top).
The user profile gives us a real-time updating view of an end user as he or she journeys trough a world of beacons. The box labeled “computed user profile” shows us the user’s preferences in a visual manner that updates automatically.
The user can add entities (we just used that name instead of beacons to have a generic model for all kinds of proximity tech, such as NFC). and assign tags to them.
Lastly, the user can create advertisements that are connected to the tags, completing the circle and also fulfilling the requirements that we outlined above.
Wrapping it up
Obviously, this is a very crude example, and some of our partners have advanced capabilities that go beyond this example. We do however, encourage Proximity Solution Providers and partners to think about this. It is a small price to pay to implement and it will increase the value of the data in the future. It is also important to keep in mind that it is possible to just store this data and apply analytics and scientific methods at a later stage. As Unacast is a data first company we cannot stress enough the importance of this.
PS: This also highlights an important part of our commercial and engineering culture and how they play together. Rather than placing an “order” from the tech team, the tech team was given great room to navigate and explore. This obviously only works if there is a high level of trust and transparency - essential components as Unacast scales up the organization in all professional disciplines.
