I am sure that in the "house of future" all devices will be lighted & switched on and off by one clapping or voice command. For example, when you come home, clapped - there would be lighted on in the hall. By clapping twice- light would be off. Being in the kitchen -by saying :Coffee: or "Sandwich", appropriate devices would revive and cook for owner. But the TV sets would work by this way the best. There is no need to search for TV remote, which always vanishes. You flopped on the sofa, ordered "TV, I want any channel- that all, watch it! Switching the channels is busing the voice as well. Isn't it a paradise, is it?
