Interactive Spaces Natural interfaces supporting gestures and manipulations in interactive spaces

This doctoral dissertation focuses on the development of interactive spaces through the use of natural interfaces based on gestures and manipulative actions. In the real world people use their senses to perceive the external environment and they use manipulations and gestures to explore the world around them, communicate and interact with other individuals. From this perspective the use of natural interfaces that exploit the human sensorial and explorative abilities helps filling the gap between physical and digital world. In the first part of this thesis we describe the work made for improving interfaces and devices for tangible, multi touch and free hand interactions. The idea is to design devices able to work also in uncontrolled environments, and in situations where control is mostly of the physical type where even the less experienced users can express their manipulative exploration and gesture communication abilities. We also analyze how it can be possible to mix these techniques to create an interactive space, specifically designed for teamwork where the natural interfaces are distributed in order to encourage collaboration. We then give some examples of how these interactive scenarios can host various types of applications facilitating, for instance, the exploration of 3D models, the enjoyment of multimedia contents and social interaction. Finally we discuss our results and put them in a wider context, focusing our attention particularly on how the proposed interfaces actually improve people’s lives and activities and the interactive spaces become a place of aggregation where we can pursue objectives that are both personal and shared with others
