Your Emotional Fingerprint on Slack

I’ve been doubting between calling it an emotional footprint or fingerprint. You leave a digital, emotional footprint be…

Improved version of the sentiment analysis for Slack. It supports mouse hover, to see the actual content. I’d make the site public but I’ll need to find a open Slack community, I guess our data might contain a bit too many internal discussions ;)

Used different colors, based on what I could find on emotions vs colors. Green-Yellow is more positive, while Purple-Pink denote more negative talk.

Played around with our HCI team’s Slack data. Using sentiment analysis to visualise how positive and negative our posts are along the week. There’s something about Sundays in my case (5th row), and our new colleague Yucheng hates Saturdays? ;)

Big robots are creepy. Small robots are too.

At ICRA 2015 in Seattle yesterday, researchers from MIT demonstrated an untethered miniature origami robot that self-folds, walks, swims, and degrades. src: IEEE.ORG (via: nu.nl)

Presented at Eurovis 2015, Cagliari, Italy. Our original approach of allowing collaborative filtering on interactive tabletops. This video was part of the Fast-Forward session (might not make a lot of sense without my voice-over). Paper should be up soon, so should a live recording of the presentation.

In the mean time, slides available here: http://www.slideshare.net/svencharleer/popi-glyph-designs-for-collaborative-filtering-on-interactive-tabletops

A tabletop application I developed in 2013 for my PhD, which is all about Learning Analytics dashboards. I'm a computer scientist, more specific in the field of Human-Computer Interaction and Learning Analytics, so the work I'll be posting is more focussed on usability, usefulness and effectiveness of data visualisation applications.

LARAe stands for Learning Analytics Reflection and Awareness environment. This tabletop setup shows the activities of an engineering class (blogs as reporting and discussion tools, twitter activitiy) and awarded badges (for specific achievements). The user can filter by student and time, compare etc.

Hey and welcome to yet another one of my online spaces. I'll be using this Tumblr to post updates on my research (if it's a long update I'll link to a Medium post) and gather/reblog stuff that's supposed to inspire my research! About me: I'm a PhD candidate at the "Augment" research group (HCI - Computer Science department) at KU Leuven, Belgium. I'm 34, so yes I've done other stuff before, such as playing software engineer and game developer. Now I'm a (mad) scientist! Head to http://svencharleer.com for more info on me!
