You mean the tech pioneered by Jackbox games. Using your phone as an adaptable controller.
Weird "patent" given the fact that smartphones are perfectly usable as PC controllers since around 2013-2014 and Nexus 4 and 5, LG G Pro, LG G2, Galaxy S4 and similar phones. Bluetooth connection is enough.
Next patent to come - touchscreens?
Wasn't this patent already used for Everyone 1-2-Switch?
