Multi-touch interaction with computationally enhanced surfaces has received considerable attention in the last few years. The rediscovery of diffused illumination and frustrated total-internal reflection principles, which allow for building such surfaces at low cost, has pushed the development of multi-touch applications forward. Although this and other related techniques have been presented in an academic setting, the steps involved in building a high quality multi-touch enabled surface, on a software and hardware level, are not trivial.

By practically demonstrating the steps involved in creating these interactive surfaces the workshop aims to encourage the exploration of multi-touch by researchers who may not have considered self-construction of such hardware viable.
