It's no secret that Google is looking to "disrupt" the gaming market - the company's Project Stream technical test ran for several months, and allowed participants to play Assassin's Creed Odyssey in a Chrome browser tab - no installation required.
Google has a mysterious announcement to make at GDC 2019, and we're speculating that announcement will regard their rumored Project Yeti console, the hardware that is expected to accompany Google's "Netflix of games" streaming service powered by Chromecast and Project Stream technology.
On the one hand, game controllers have more or less become standardized these days.
One touch that's distinctively Google-esque is what looks like a voice control button in the center - a way of calling up Google Assistant perhaps while you're in the middle of a gaming session.
Unsurprisingly, a few talented artists have given those patent diagrams a more polished form, taking cues from Google's own design language. The patent shows a number of line drawings for the controller which features a traditional D-pad, twin thumb sticks, four primary buttons and a four triggers buttons.
Thurrott reported on the discovery of the patent application which is for a notification system between the contoller and its console counterpart. Given how mmost game controllers lean towards black colors, this Google controller will easily stand out. A lot of the language seems to be geared towards a client-server system that sounds a lot like a game streaming system.
