Researchers from Philips Electronics plan to describe a jacket they have lined with vibration motors to study the effects of touch on a movie viewer's emotional response to what the characters are experiencing. The jacket contains 64 independently controlled actuators distributed across the arms and torso. The actuators are arrayed in 16 groups of four and linked along a serial bus; each group shares a microprocessor. The actuators draw so little current that the jacket could operate for an hour on its two AA batteries even if the system was continuously driving 20 of the motors simultaneously."
