Start of Laevo user studies


As part of my PhD I created Laevo, an alternate way by which work can be organized under Windows 7/8, and now it needs to be evaluated by several participants during a 2 week study. Laevo augments your current windows environment with a couple of extra options to organize your daily activities. The goal is you attempt to use these features during a full 2 week period, while continuing doing the activities you ordinarily do. How much you want to use the system is entirely up to you, but ideally you have it running during the full 2 weeks. You can either exit Leavo at the end of each day, or use Window’s sleep and hibernate functionality.

You would help me out greatly by installing Laevo, and trying it out. You can start the 2 week period of using it either on Monday the 5th, 12th or 19th of August. At the end of each day please give some feedback on your experiences with the system that day by shortly answering a set of questions. This shouldn’t take longer than 5 minutes/day. You can compile the feedback in one document and send it to me at the end of the 2 weeks (sjeu AT

  1. Why was or wasn’t Laevo useful for you today? At a minimum state one positive and one negative points, but open feedback is encouraged.
  2. What activities have you done today that weren’t represented in Laevo at some point?
  3. What was/were your main activities today? In case they were represented in Laevo, where did they originate from (self-initiated, to-do item, email to-do, other)?
  4. Have you scheduled any activities today? Did you also plan them on the time line? Why (not)?
  5. Did you use Leavo’s to-do list today? Why (not)? How?
  6. Did you use Laevo’s Activity Context library today to store or retrieve files?
  7. Were there occasions where you considered creating an activity or to-do item but eventually decided not to? If so, why?
  8. Please have a look at your time line. Does the overview of today reflect the actual activities you did today? Why (not)?

You can contact me for any information on sjeu AT, but I will be out of office until the 11th of August.

When the application crashes there should be a “log.txt” file available in “C:\Users\<username>\Documents\Laevo”. Please email this to me. In case you continue encountering problems which severely hinder you from your work, please report them so I can try sending you a new version of Laevo to resolve the issues.

Please forward this to any participants which might be interested. Thank you for helping me out!

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.
