According to the description, Sony is exploring the possibility of connecting a controller to a mobile phone. The smartphone is planned to be attached to the pad using a magnetic holder, after which it will work as an additional module, expanding the functions of a classic gamepad. This will allow the use of the touch screen, gyroscope, camera, and motion sensors of the smartphone in games.
According to the patent, the smartphone can serve as an additional screen, displaying maps, additional menus, or other information, leaving the main screen cleaner. The company is also considering using the phone's camera to create avatars and introduce game mechanics based on the physical movement of the device.
The idea of using smartphones as auxiliary controllers is not new, but modern technology and connection stability can take this experience to a new level. So far, this is just a patent, and it is unknown whether the function will appear on PS5 or become a feature of future systems.
