Smart rooms contain smart chairs that measures body posture:

'Tekscan' sensor sheets (42x48 force sensitive resister arrays) detect pressure 'Images' recognized with algorithm originally design for face recognition Transformed data statistically compared by "distance-from-feature" space Additional applications: Deployment of airbag forces Ergonomic data for furniture design Computer security
