All the definitions proposed leave little room for multimodality. However, augmented reality
has today exceeded the stage of repositioning virtual indices in a video flow and now also
proposes sound and even tactile augmentations. In [6] we proposed a more general definition
of augmented reality as being the combination of physical spaces with digital spaces in
semantically linked contexts. We can say that augmented reality is the combination of
physical spaces with digital spaces in semantically linked contexts for which the objects of
associations lie in the real world. On the contrary, we can define augmented virtuality as
being the combination of physical spaces with digital spaces in semantically linked contexts,
but where the task’s objects lie in the world of computing, states that the systems considered
aim to make interaction more realistic.
