Nintendo released a patent yesterday about the Switch 2 Joy-Con controller, which shows that it can be used as a mouse, which is consistent with previous reports. The patent shows that the Joy-Con controller is equipped with an optical sensor on the side, so it can be used as a mouse. The patent also reveals that each Joy-Con controller can also be connected to a "peripheral" device, which suggests that Nintendo is expected to launch a mouse-style shell for the Joy-Con, making it feel closer to a mouse.
