Nintendo has taken a major step to address the persistent problem of stick drift in its Joy-Con controllers. The company recently filed a patent that proposes the use of a “smart fluid” in joysticks to solve the problem.

The patent describes a joystick that contains a  “magnetorheological fluid” (MRF)  This fluid adjusts its viscosity based on the strength of a magnetic field. In practice, this means that when a player moves the joystick, the fluid becomes thicker, creating resistance. As soon as the player releases the stick, it automatically returns to its original position. This innovative concept is similar to the “Hall Effect” sticks used in some modern third-party peripherals to prevent stick drift.

The patent does raise some questions, however. It remains unclear whether Nintendo will allow developers to adjust the resistance of the joystick, similar to the DualSense controller of the Playstation5  Also, it is not yet certain if this new stick design will be incorporated into upcoming Nintendo consoles or if it will provide a solution for the current Joy-Cons.

Stick drift is a common problem that affects many controllers. The Nintendo Switch in particular, which has been a global success, has seen increased reports of this annoyance. Despite the company’s efforts to fix the problem, repairs are still frequently required However, Nintendo seems determined to find a long-term solution that will provide gamers with a smooth and reliable gaming experience. The gaming community is eagerly hoping for further developments and to see if this innovative patent actually becomes a reality
