In this paper we present the first version of DUL Radio, a small, wireless toolkit for sketching sensor-based interaction. It is a concrete attempt to develop a platform that balances ease of use (learning, setup, initialization), size, speed, flexibility and cost, aimed at wearable and ultra-mobile prototyping where fast reaction is needed (e.g. in controlling sound). The target audiences include designers, students, artists etc. with minimal programming and hardware skills. This presentation covers our motivations for creating the toolkit, specifications, test results, comparison to related products, and plans for usage and further development.
