That Apple is toying with a bunch of varied gaming controller concepts is anything but unknown. Two years ago, an interesting Apple patent detailing an accessory for playing games with portable devices surfaced in the United States Patents & Trademark Office's database.
It was originally filed back in September of 2008, meaning the company had likely begun researching the invention ahead of the original iPhone debut five years ago. The patent outlines a few exciting gaming accessories for portable devices, such as a receptacle system of sorts that could let your iPod be inserted to play games.
Another highlight worth mentioning is a gaming controller featuring cameras, motion sensing, a dual-display configuration and physical buttons on the back coupling a multitouch surface on the front.
