IoT Expo at IoT week 2019 Aarhus

We participated at the IoT expo at Ridehuset during IoT week 2019 in Aarhus. [ ]

Mindreading is all the rage

We brought our Muse headbands to the expo as a way to start a conversation about how quickly we generate data, and just how incredibly much our brain creates in no time. [ ]

The headbands was originally created to help with meditation training. They measure different brainwaves, while providing audio feedback through an app, indicating if the right meditative state of mind is achieved.

In reality they are relatively cheap EEG devices, and as such scientist have been using them to conduct experiments. This has seen them developing an app that can plot the data coming from the muse headband, using different graphs and raw numbers. This is the app we use to show, just how quickly we generate data with our mind. While the meditation app is used to lure people in and listen to us talk endlessly about data.

Meditation 9 to 5

The expo was visited by a great number of school classes from the greater Aarhus area. Who were all very interested in trying out meditation while getting their mind read. In actuality the interest was so great that we had long lines in front of our booth.

We had a lot of interesting conversations about relaxation, point scoring in the muse app and how relaxation can be more than an activity.

Patiently awaiting their turn to try the headbands in the meditation chairs

While a lot of our visitors were a bit to young for the entirety of our data agenda, we had a lot of interesting conversations with their teachers, and other participants at the expo.

And while the age of some of our participants might not have been entirely compatible with a hard data conversation. We had a lot of interesting conversations about relaxation, point scoring in the muse app and how relaxation can be more than an activity. Relaxation might be a state of mind, and not just watching youtube videos on the couch.

The muse headband and the data the children are immediately presented with (audio cues), allows us to somewhat share a mindstate. Having a common starting point, or at least, a common reference. We can discuss relaxation and what it is for us, to a much greater degree. Something that might be very needed in this time of constant input.

Infographics for everyone

We held our first workshop teaching citizens how to make their own infographics.

The aim of the workshop was highlighting how the participants could use readily available online tools for creating their own graphically infused stories.

Instead of focusing on the data aspect of the project, we tried in this instance to engage the citizens by helping them create the story they wanted to tell. Be it a CV, an invitation, or maybe a presentation for work visualizing, on a map, where the company’s assets were.

By helping the participants work towards an actual product, and teaching them tools and useful tricks to get there, the proces of creating (data)stories becomes concrete. Our thesis then, is that a future incorporation of data, to corroborate and strengthen your story, is more likely when the proces of creating a data story is less nebulous.

Workshop format

The workshop consisted of three major parts. First an introduction to using data in stories. Then a design- and tool introduction after which we started the work phase.

In the first part we introduce the concept of infographics and data stories; how they are used, different examples, and why they make sense. When data is everywhere making sense of it, quickly becomes a problem. Infographics and data stories are sorely needed if we want to tell or inform about subjects with complexity. We keep this introduction light and short.

after a brief design and tool introduction, we encouraged the participants to start working, relying on the usability of the tool to do most of the heavy lifting.

After our introduction to infographics and data stories, we start up with the design part. This is not a comprehensive design course in any way, but getting around basic concepts used in graphical design is helpful for the participants, in creating good looking infographics. We focus on concepts like complimentary colors and the difference between raster/bitmap and vector formats. Which tools to use, and so on. So, after a brief design and tool introduction, we encourage participants to start working, relying on the usability of the tool to do most of the heavy lifting.

The Tools

We used canva to make the infographics. Canva is a browser-based infographic tool. It is one of many options available online. We mostly chose canva due to the fact, that the non-paid option allows you to upload and output a product, almost hassle-free. There are some restrictions on output formats, but nothing really problematic. Our experience from the workshop is that the tool is easy to use – both for the tech literate and the ones less so. There are many other options out there that provides the same sort of service, and we of course encourage you to find the one that suits your needs the best.

  • Color.adobe is a tool for choosing complementary, monochromatic, analogous and so on colors. Great for avoiding the less fortunate color combinations.
  • Flaticon is one of many sites that offers free icons in different vector formats.
  • Pexel offers free high quality stock photos. Being free and high quality the selection is more limited than you will find at a paid site or a free one with a lower barrier for entry. It is a good starting point though, and will help the participants create more attractive infographics.
  • Vectr & Pixlr browser-based vector and image editors. Great for quick changes.


The workshop went exceedingly well. The participants quickly got to work on all manner of projects. The usability and ease of use in canva allowed almost everyone to get started right away with minimal help from the instructor.

All participants indicated during feedback, that the short introductory parts were very helpful in establishing and understanding the subject. The short timeframe ensured that it did not get too theoretical, while still being informative.

Letting the participants start working on their project in canva quickly was uniformly enjoyed. This is likely due to the fact that canva, and other browser-based software, is often very easy to get into for most people.

All in all the workshop went well, and can be easily adapted to other libraries.

Teens Measuring Brainwaves

Data literacy through self tracking

Discovering that teenagers may not be inclined to immerse themselves into data work, we will this Spring be testing new concepts and ideas, to investigate how we might grab their attention.

One topic that seems to transcend age and gender is the universal subject “me”. A deeper understanding of oneself is something most people long for, and is probably part of the reason self-tracking has become such an integrated part of our everyday lives.

Teens are furthermore known for being notoriously self-absorbed, and with that in mind, we wanted to do workshops for schoolchildren using the MUSE headbands. By letting them measure their own brainwaves, we were hoping to titillate their curiosity, and motivate them to working with visualizing the data afterwards.

The MUSE headbands are very easy to set up, and we use the app Muse Monitor to track and record the brainwaves. The recordings can be directly added to a Dropbox in .csv format.

The next step is to import the data into a spreadsheet (e.g. Microsoft Excel), and without detailed knowledge of data cleaning or analysis, convert it into different charts and diagrams.

We were aware, though, that the teens needed precise instructions, in order to perform the tasks in the workshop. Still, we were surprised by how much instruction they actually needed.

They were as expected very interested in the MUSE headbands, actually so excited that they created way too many and inaccurate data sets, instead of following our instructions and focusing on getting two-three useful data sets.

Another challenge was the openness in interpreting brainwaves. The teens were expecting to get a straight answer – e.g. if my brainwaves look like this, it is because I’m [smart or creative or easygoing or…] and working with brainwaves (and especially as your only source of input) there is no clear 1-to-1 mapping. So, they were a little disappointed by the results.

“They were scientists finding out the best ways to get teenagers to be sleepy (and get to bed at an reasonable hour).”

On the positive side, they were engaged and all of them eager to see their own brainwaves. They were also convinced by the frame of the workshop: They were scientists finding out the best ways to get teenagers to be sleepy (and get to bed at an reasonable hour). Though the concept of a study design was both difficult and new to them.

At this moment we are adjusting the scope and structure of the workshop. We need even more detailed instructions and we need to scale down a little to spend more time on the essentials:

  • Study design: What does the angle of our research mean in terms of the data we collect?
  • Data gathering: Why is it crucial we follow our initial study design instead of just going with the flow and creating lots of excess data?
  • Data visualization: What happens when we clean and analyse data, so it can presented in a visually appealing way?
  • Datastory: How do we create a context or narrative around our data, to make it compelling?

When we are done adjusting, we will be doing another set of workshops for schools during Fall 2019. We will later this spring also be testing the MUSE headbands with the library users, and see if they will be equally curious to see their own brainwaves.
