In this paper we comment on design teaching and communication in the domain of architectural education, particularly in the initial parts of the design process, where hand sketching is applied. We are aware of advantages that electronic sketch devices incorporate, therefore we investigate their implementation in diverse phases of architectural studio education. We are testing our presumptions on site, running an experimental design studio with students at two universities: ETH Zurich and CVUT Prague. The focus lies in configuration and further use of Value Lab in teaching and in an adequate sketch application development. The tool is called ColLab sketch and its multi-interfacial manner fits large touch-tables as well as small tablets
