 SAN JOSE, Calif. (AP) - Sony Corp. and Immersion Corp. said Thursday they have settled their long-simmering patent dispute over the vibration technology that shakes video game controllers, and will work together to bring the so-called "rumble" function back to PlayStation products.
The litigation threatened to halt Sony's U.S. sales of PlayStation and PlayStation 2 consoles, controllers and games that use Immersion's "vibro-tactile" technology. The patented technology adds a sense of realism to videogame play by jolting the player's hands whenever there's gunfire, explosions, crashes or other dramatic on-screen events.
Immersion's shares jumped nearly 32 percent in after-hours trading, while Sony's stock plunged 6.2 percent to 5,830 yen ($49.36) in Tokyo Friday.
