Sheep Dalton posted this definition and explanation of the term ‘tangible interaction’… Worth a read.
‘Tangible Interaction has come to be the ‘umbrella term’ used to describe a set of related research and design approaches which have emerged in several disciplines. It became noticeable as a research topic in the late 90s and then rapidly grew into a research area.
Broadly, Tangible Interaction encompasses user interfaces and interaction approaches that emphasize
- tangibility and materiality of the interface
- physical embodiment of data
- whole-body interaction
- the embedding of the interface and the users’ interaction in real spaces and contexts.’
