Hi! My name is Dominikus Baur and I'm a Data Visualization & Mobile Interaction Designer from Munich, Germany. I love crafting well-behaved systems where you won't even notice that thin interface between you and your data.
I blog about touchable visualizations, data visualization in general and mobile and touch-based interaction design.

You should talk to me: do@minik.us @dominikus


Interactive iPad Scatterplots

Another research project from this year that tackles multi-touch visualizations: Ramik Sadana's and John Stasko's Designing and implementing an interactive scatterplot visualization for a tablet computer. The authors came up with several neat interaction techniques for massaging the data presented in a scatterplot in various ways.

When I saw the excellent presentation by Ramik at AVI 2014 back in May, I was very reminded of my own Touchwave project - different visualization technique (scatterplots instead of stacked graphs), but related interactions based on the vocabulary of the iPad. I guess just one more such touchification paper until we see a taxonomy for touch-based interactions published...

Anyway, here's the video:


Kinetica (CHI 2014) goes DataSquid

I've been meaning to mention this project for a while now: Kinetica: Naturalistic Multi-touch Data Visualization by Jeff Rzeszotarski and Niki Kittur from Carnegie Mellon's HCI team is a fascinating look at what interaction with data can be like when you start from a purely touch-based premise.

The basic idea is to have every data point as an actual point on screen and give people several physics-inspired tools to explore it. Tools shown in the video are "walls" that filter for certain criteria and free-form "magnets" that attract data points, again based on certain criteria:

This concept was so appealing that Kinetica spawned a startup: DataSquid takes the same approach and lets you analyze your data using these multi-touch physics. Here's a demo from their website:

It's still invite-only, but it looks like it could have a great future! Dare I say Multi-touch Tableau?


Everything except the chart - tutorial at IEEE VisWeek 2014

Moritz Stefaner and I gave a tutorial at this year's IEEE Visweek in beautiful Paris. In 'Everything except the chart' we summarized everything we've learned about how to develop complex, web-based visualizations - except how to build the charts themselves. We've talked about things like our development process (Coffeescript, SASS, grunt, etc.), how to social media, and how WebGL is the hottest new thing out there for 3D piecharts (irony is hard on twitter!).

Anyway, you can find our code examples here and the slides right here (click to focus and navigate with arrow keys).


Multi-touch cleaving

(via @blprnt)

Today I stumbled upon a quite nice interaction technique that The Office for Creative Research developed for their Specimen Box project (in conjunction with Microsoft's Digital Crimes Unit). Their 'cleaving' lets people split the visualization into two with a simple two-handed gesture. This, of course, works especially well on a nice large digital display:

The whole project is chock-full of interesting touch-based interactions, so check out all videos about Specimen Box.


Selfiecity and OECD Regional Well-Being win KANTAR Information is beautiful awards

In yesterday's KANTAR Information is beautiful awards both Selfiecity and OECD Regional Well-Being scored big: we won Gold and Silver in the 'Website' category! Congrats to the teams and the other winners!


Animated transition for details-on-demand on mobile

Here's a nice little chart interaction technique built by Simon Rood in FramerJS that I stumbled upon on Facebook. On a desktop, showing details-on-demand is pretty much always done using hovering, but on mobile it's still tough (see my JSConfEU talk). Simon's animated transition looks like a smart way to do it:


JSConfEU talk online: Web-based vis on mobile

Back in September I gave a talk at the great JSConfEU 2014. The conference was three days of nerdy Javascript-details - highly enjoyable! My talk was on data-vis on mobile devices and I tried to shed light on some of the gritty details that Moritz Stefaner and I discovered over the various responsive projects we did. It also gave me the chance to conserve my beard in video-form for all eternity.

Metrico review

Digital Dreams recently released Metrico, a game for the Playstation Vita, whose marketing focused on its infographics-inspired aesthetics. The game boasts a minimal and geometric style and is filled with all your favorite charts - yes, even pie charts! From a game perspective, however, Metrico is less than stellar and it would be a disappointment if this was the best Infographics: The Game we ever got.

HTML5 Geolocation and User Experience

The W3C introduced a new client-sided way to detect a visitor's location with the HTML5 Geolocation API. For the OECD Regional Well-Being project, we decided to give this new way of learning about a visitor a try and get them started with the visualization in their home region. However, actually providing them with a nice user experience while moving through this somewhat complex process proved to be difficult. In this post, I'll discuss our issues and workarounds.

OECD: Regional Well-Being

Well-being exists on a scale from the individual to whole countries. In the OECD Regional Well-Being project - a part of OECD's Better Life Initiative - we dive deeper into this hierarchy: the interactive, web-based visualization shows various aspects contributing to quality of life for over 300 regions all over the world. In this post I'll discuss the project as a whole and its design decisions (with more technical posts coming up).
