Everyone interested in OLPC or is doing some project concerning OLPC respectively, can sign on this map here:

For me, it shows better than s/th else, that space matters. One day after signing our project on the map, I got an email from Nick interested in our work. Nick is doing also some map stuff for the OLPC (like Map activity, OfflineMaps, and MapStats). However, it’s likely to merge some work, when I get some more free time getting back to XO coding .. I’ve still some things on my stack 🙂

Film about the project

Sorry for being absent for so long time. Thomas became father for the first time (congratulations again Thomas!) and me was quite busy since I finished my study. Getting into working life takes more time as I thought .. However, we found it very important to sum up our work we did so far in a short film. Not only for us but also for others who want to get an idea of Weiterlesen

It’s done ..

.. not the project so far, but my Diploma Thesis!

To be honest, I submitted my thesis already in the beginning of October, but now I got the information that I passed, yay! No marks from my supervisors, yet, but at least an official confirmation to pass my diploma.

However, if you are interested in the contents and results, feel free to download your own copy of it. I just corrected some smaller typos a week ago as you may know, you always find new typos in a thesis — even if there were 10,000 friends reading it. I believe that this is a common phenomenon (I observed it several times and everybody I talked to confirmed it)!

Kagugu School Day5: Collaboration (2nd try) and Final

After solving some technical problems which rose up due to cloning the laptops, we started a new approach testing the collaboration of the Geo Activity. We spent much efforts implementing the collaboration capabilities the XO laptop (and Sugar) offers. Performing games with others is much more fun, and besides this the learning effect grows exponentially.

Like on the other days, we tried the Geocaching and the Geotagging game. But now with sharing the activity, instead of performing single games in parallel.


First we tried the Geocaching activity which was pretty much fun — not only for the kids participating the game ;). It was fun to see, which ways the kids chose to find the cache. We even did not have to follow the kids directly, as we saw them on the map striving around the schoolground.


The trick was to orientate oneself with the help of the map and the player constellation. When the treasure was close, the kids could disable displaying all participants on the map, so they could concentrate on the stepapproaching the treasure (overlapping of XO icon and treasure icon), without being confused of the other players icons.

For the Geotagging game, unfortunately we had not too much time and I’m lacking some pictures (I guess, we forgot to take some „screenshots“), but besides some bugs (kids could not delete a tagged object) it works also very well. We will provide pictures on this after further tests back in Germany.

We finished this impressive week with some post tests on spatial abilities and sketch maps in both shifts, to measure possible improvements.

To say goodbye to the kids we brought some sweets from Germany and made group pictures, with XOs and with the flag 😉 We’ve let some of the GPS devices in class, so the kids can continue geocaching and geotagging in the future.

Finally we had an interesting summing up talk to the teachers and the headmaster. Kagugu Primary School is highly interested in establishing some kind of exchange of data with other schools, starting with the Bodelschwinghschule Münster. We put this on our todo list, to develop a server for publishing the maps made with the GeoActivity. Theodore was even asked by the headmaster to give teacher trainings for the GeoActivity in the future!

30,000,000 Laptops for Africa

This has been announced by the BBC two days ago.

However, as I read this news first by reading a german article at, I wanted check the figures, since for me 30,000,000 is a huge number (not to say here, this amount would not be needed at all). Reading the EAC announcement it exposed that the message is only a letter of intend, and no concrete figure was mentioned here.

BBC might have some insider information or the 30,000,000 laptops were just a guess (I think this might have been said in their article).

Preparations in Kigali

Our first week in Kigali was predominantely coloured by connecting people and preparing the following week’s work. That work contained the mapping of the schoolground, doing some paper tests with the children, having contacts with local contacts and preparing the installations on the school’s XO laptops. Talks to the local OLPC organization and the Ministry of Education gave us some directions for the upcoming tests of our activity. We settled in the local ESRI office and tried to see get to know parts of this fast developing city.

Here are some impressions of Kigali:

Kigali 041 Kigali 047


Not to forget the Kagugu Primary School where the tests will take place:

Kigali 029 Kigali 015

After the installations some teachers could try the activity and we had a lot of fun with the children.

Kagugu Vortest 015

While installing our activity on the school’s laptops we have found some „very special“ activities…

Don’t to forget the Kagugu Primary School where the tests will take place

Mapping Kigali

During our work in Kigali, we are mapping openstreetmap data. Not only for the school where we performing our tests, but also other parts of Kigali city. Theodore for example was excited collecting data in his sector and enjoyed to create his very first map on OSM. Have a look on PRE and POST:

Screenstory I

Hey out there,

took a long time since I posted the last progress step. We did some tests again in Bodelschwinghschule and refined collaboration functionality for the Geo activity.

We created some screenstories which tell you more about the workflow for each plugin we can provide for now (Geocaching and Geotagging). This is the first screenstory telling about the Geocaching, a later blog article will give you information about Geotagging.

First startup the Geo game and choose the Geocaching activity.

After our first test at Bodelschwinghschule we are planning further tests. Our activity and the plugins are growing, so we would like to test how the actual learning benefits are, when playing around with the Geo activity. Therefore we create some pre-/posttests which will indicate such benefit.

Our near future road map looks like this:

Feb 22–Feb 23, 2010 Workshop
Mar 22–Mar 26, 2010 Further tests at Bodelschwingh- schule, Münster, Germany
Apr 26–May 7, 2010 Tests and Evaluation in Kigali, Ruanda

Furtheron another Hack Night is going to be planned.
