Sony is filing patents for a new, spherical controller that could add a new level of emersion to VR gaming. Several such patents have been filed by Sony over the past few years, hinting at interesting new features for the PlayStation 5 or a future gaming console. These include new systems that can track a player's eye movements and provide in-game responses or even add odor to the gaming experience like the old Smell-O-Vision systems. Other Sony patents suggest that the company is working on improved parental controls or gameplay roulette systems that could give recommendations based on titles the user has already played.
