Watch, Listen, and Feel Movies with a Haptics Jacket
Paul Lemmens, a Philips senior scientist, explains that the jacket isn't meant to make viewers feel the actual punches and blows that the actors are receiving on the screen. Rather, the intentions are more subtle. The jacket's purpose is to make viewers feel anxiety and other emotions through signals such as sending a shiver up the viewer's spine, creating tension in the limbs, and creating a pulse on the chest to simulate a rapid heartbeat.
"People don't realize how sensitive we are to touch, although it is the first sense that fetuses develop in the womb," said Lemmens, who will be presenting recent research on the jacket at the IEEE-sponsored 2009 World Haptics Conference 2009, in Salt Lake City.
To produce these emotional sensations, the jacket contains 64 independently controlled actuators, which can cycle on and off 100 times per second. Because of the way the brain perceives touch, only eight actuators on each arm placed six inches apart are enough to cover sensations on the entire arm. The system uses such a small amount of current that two AA batteries could provide power for an hour if 20 motors were operating simultaneously.
The jacket can respond to signals encoded in a DVD, or it can be controlled on the fly, adding another element of reality to entertainment.
