US Homeland Security is funding a new screening project that makes use of commercially available sensors to measure things like your heart rate and body temperature - and one of the components, for now at least, is a Wii balance board.
"Studies are now under way to determine whether there is a level of fidgeting that would suggest the need for secondary screening." Brilliant.
The overall technology also uses sensors for heart rate, breathing, eye movement and things like that, and is known as FAST - Future Attribute Screening Technology.
Its masters envisage it being used to speed up security screening at places like stadiums and airports.
The good news is that according to the man in charge of the project, none of this is an invasion of privacy, because we're not being asked anything, just observed from a distance. So that's alright then. Move along.
