By Felipe Erias Morandeira. In an analogue way to traditional hand-drawn sketching, we can sketch interactions and experiences when creating software solutions. These quick and inexpensive sketches are not only an invaluable tool for generating and exploring new ideas: they are also a great way to communicate initial design decisions and involve more people from the community in the design process. The talk will start by defining sketching and positioning its role in a general design process. It will then present a number of techniques than may be used to sketch interactive solutions, ranging from simple pen and paper to Free SW tools and frameworks. Several examples of real-world work from academical and Free SW communities will be discussed.
