Call for Laevo user study participants


With great pleasure I can finally announce the first public installer of Laevo, a project I started out working on as part of my master’s thesis, and am now continuing working on as part of my PhD. In short, it allows you to organize your work in new ways which Windows traditionally doesn’t offer you. In case you spend most time of the day working on your PC you might be interested in trying it out. The project has come a long way and is finally ready for the greater public, hence I am looking forward to your input on what you think about the system. You would help me out greatly by installing Laevo, trying it out for one to two weeks, and giving feedback on it afterwards. Please send me an email (sjeu at or simply contact me in case you are interested in participating.


You can download the latest version (v0.1.3) here. This is a more recent version than the one I linked to on twitter earlier this week. In case you already installed the previous version, simply uninstall the old version and install the new one. Your data and settings will be saved. To get you started I strongly advise you to quickly read through the manual so you know about the functionality offered.

I have a PhD in Human-Computer Interaction and am currently working both as a software engineer at iMotions and as a postdoc at the Technical University of Denmark (DTU). This blend of research and development is the type of work which motivates and excites me the most. Currently, I am working on a distributed platform which enables researchers to conduct biometric research 'in the wild' (outside of the lab environment). I have almost 10 years of professional software development experience. Prior to academia, I worked for several years as a professional full-stack software developer at a game development company in Belgium: AIM Productions. I liked the work and colleagues at the company too much to give up entirely for further studies, so I decided to combine the two. In 2009 I started studying for my master in Game and Media Technology at the University of Utrecht in the Netherlands, from which I graduated in 2012.

  1. This does sound interesting in that it’s a calendar with highly enhanced functionality in which a lot of thought is being put, but sadly, unless it fully and seamlessly syncs with my Android phone’s calendar, this is absolutely useless to me…

    It’s definitely an interesting initiative, though. I’ll keep an eye on it.

    1. Naturally, eventually that’s (part of) the idea. Hence Alpha v0.1. ;p Unfortunately it’s a research project and I have to prioritize what to work on first. Synchronization isn’t that straight forward to implement and poses many new design questions. What would it mean to ‘seamlessly sync’, and is that even desirable? Therefore I am first releasing this version to collect initial impressions. Thank you for your interest!

  2. It sounded promising and I decided to give it a try, however I got it crashing after just 3 minutes of use. Is there anywhere you save a log which I can provide you? or should I just describe what happened that made the application crash?

    1. Yes, check the folder “C:\Users\username\Documents\Laevo”. There should be a “log.txt” file there. Please email this to me. Describing what happened is also really helpful, especially if the steps are reproducible. P.s. I just fixed a bug where you had a to-do item (the icons at the bottom) open (thus a yellow border), which you then dragged to an activity on the time line. This is now fixed:
