According to the report, they claim that insider sources have told them that the iPhone 6 could come with a new tactile feedback linear motor. This means that instead of a single type of vibration, the vibrations could vary from strong to weak. The strength of the vibration would depend on the app and possibly even which part of the phone is being touched.
Their sources note that the technology could cost 2-3 times more than the current vibration motor used in the iPhone 5s which has been pegged at around $0.60. This is an interesting claim but not a completely surprising one. Apple has expressed interest in haptic technology in the past, even going as far as filing a patent for it back in 2009. One of the examples they gave was the use of haptic feedback on webpages.
Of course patents are in no way indication of what Apple’s plans are. It could simply be the company expressing their interest or protecting their intellectual property. In any case take this rumor with a grain of salt for now, but what do you guys think? Would this make for an interesting device?
