We present a new interactive multimedia system for blended learning called PowerChalk. The goal of PowerChalk is to provide a robust, reliable, usable and sustainable multimedia technology to any intelligent environment focused on blended learning. The software architecture allows adapting the system to any hardware configuration and supports collaboration, communication, creativity and learning. In this sense, PowerChalk resolves many limitations of current e-learning systems, improves human-computer interaction for the management of different kinds of hardware and data and allows to implement different configurations for intelligent environments.
