Immersion Corp., recently headline-makers for their legal action against Sony for the DUALSHOCK rumble technology in the PlayStation 2, is being talked about again.
Immersion's TouchSense technology reportedly allows for force feedback to be used in motion-sensitive controllers; at this past E3, Sony dropped force feedback from the PlayStation 3 because they said it conflicted with the controller's newly-announced motion sensitivity. Immersion president and CEO Vic Viegas told 1UP he believed Immersion could help Sony re-add this feature if they moved quickly.
Nintendo's Wii Remote, on the other hand, features both motion sensitivity and rumble. Immersion hasn't had a hand in this; the technology has been developed by Nintendo without Immersion's assistance. 1UP speculates Immersion may be giving the Wii Remote a very close look when they're able to get their hands on one to see if their methods violate any of Immersion's patents—which has the potential to land Nintendo in legal action not unlike that which Sony has already faced over DUALSHOCK.
