Are you ready for the "feelies"? A Bell Laboratories engineer has developed a device which créales false sensations of touch. Engineer Michael Noli calis the gadget a "machine communication tactile device"-or "feelies" for short. The machine enables people to feel three dimensional objects that don't exist, by using a computer hooked up to a grasped knob. The computer can cause a person to feel a rubber sphere suspended in space, a cube, or several other shapes. Varíety magazine suggests that feelies might some day be used in conjunction with home tv to créate all kinds of weird impressions.
