A newly published patent application for Nintendo shows the company is interested in new ways to provide haptic feedback in a portable device. Given the preponderance of portable-related patents recently, it would be easy enough to load this one onto the Nintendo NX hype train and let it roll. But some of the illustrations indicate another potential use.
The patent (which was published in the US on June 30, but was filed on December 3, 2015, in the US and way back on December 26, 2014, in Japan) is a handheld “information processing apparatus” with a vibrator between two speakers. No, not that kind of vibrator. The speakers can be used to emit stereo sound and the vibrator can work in concert or independently of them to make a more convincing feeling of movement than the now-standard “rumble”.
Then again, it could always be both! If NX turned out to be a high-powered smartphone (maybe running Android, as the old rumors say) that could play The Legend of Zelda: Breath of the Wild on your TV, that would be a very Nintendoian way to address the “nobody buys handhelds because everybody plays games on mobile devices” problem.
