Abstract : Most of our waking hours are now spent staring at a screen. While the advances in touch screens have enabled a more expressive interaction space with our devices, by using our fingers to interact with digital content, what we see and manipulate on screen is still being kept away from us, locked behind a glassy surface. The range of capabilities of the human senses is much richer than what screens can currently offer. In order to be sustainable in the future, interaction with the digital world should leverage these human capabilities instead of letting them atrophy. One way to provide richer interaction and visualization modalities is to rely on the physical world itself as a host for digital content. Spatial Augmented Reality provides a technical mean towards this idea, by using projectors to shed digitally controlled light onto real-world objects to augment them and their environment with features and content. This paves the way to a future where everyday objects will be embedded with rich and expressive capabilities, while still being anchored in the real world. In this thesis, we are interested in two main aspects related to these tangible augmented objects. In a first time, we are raising the question on how to interact with digital content when it is hosted on physical objects. As a basis for our investigation, we studied interaction modalities that leverage traditional input and output devices found in a typical desktop environment. Our rationale for this approach is to leverage the experience of users with traditional digital tools – tools which researchers and developers spent decades to make simpler and more efficient to use – while at the same time steering towards a physically enriched interaction space. In a second time, we go beyond theinteraction with the digital content of augmented objects and reflect on their potential as a humane medium support. We investigate how these augmented artifacts, combined with physiological computing, can be used to raise our awareness of the processes of our own bodies and minds and, eventually, foster introspection activities. This took the form of two different projects where we used tangible avatars to let users explore and customize real-time physiological feedback of their own inner states.
