General framework With the fast technology development some traditional techniques of human activities are turning into digital, supported by new devices. In this paper we are specifically focusing on sketching as an unavoidable part of architectural design in the initial parts of the process (Goldschmitt, 1994). Additionally, we are investigating collaboration over the Internet between two separate groups of students in two different countries. The collaborative setting introduces obviously some technical issues but it also puts emphasis on the shared medium between the students. We are setting up an experiment with two groups of students cooperating over distance. FA CVUT is meeting ETH Zurich using PragueLab and ValueLab. The equipment at each place tested is very different, therefore our test proves the compatibility of ETH state-of-the-art systems of collaboration, consultation and education (Halatsch, Kuntze and Schmitt, 2009) and the more common, low-tech set-up of FA CVUT. The experiment should result in finding a working scheme for collaboration using different types of device, programs and teaching schemes[fig. 1]. We are using a variety of scientific methods in the experiment during the collaborative seminar: We are creating a questionary for the participants, testing the devices (PQLabs multitouch overlay, iPad, Vacom) and the programs (AdobeConnect, JoinMe, ColLabsketch), the ergonomic aspects of using big touch screens for sketching and big screens for presenting and, in the end, both technologies together for consultation.
