We present our gesture-based interaction system for multitouch surfaces, called Evolve-Touch. The main feature of our system is its personalization capacity so that user can define his set of gesture and add new gestures at any moment. The system is based on our evolving recognition engine, Evolve++ that can be trained incrementally, starting from few data samples. Evolve-Touch includes a complete mechanism to allow user to manage his gesture sets for different application contexts in simple and user-friendly manner. An intuitive mechanism is adopted to get user feedback on recognizer answers, which allows the latter to continuously enhance its performance. Moreover, we integrate into the global system a multi-touch object manipulation modality with a simple mode switching. The showcase application presented in this video demonstrates the main features of Evolve-Touch system. Evolve-Touch is protected by a patent.
