SketchIn is a multimodal tool which allows different and individual ways of communication. Instead of translating a kinesthetic feeling into an abstract parametric language we define interactions by actually performing them. We sketch compositions in a 3D-Space. 

The control of movement is based on intuitive gestures. This tool also helps us to stay in our work flow of ideas.

Why sketching interactivity? Why not creating interactivity?

I think that the word sketching leads to a more narrowed design solution driven by the benefits of the process of sketching. Sketching serves us as a thinking tool which enables us to start a dialogue with ourselves. Sketches encourages constructive discussions which gives everyone the permission to consider honestly and with no hesitation.
