In the ever-evolving landscape of gaming technology, Nintendo has made a significant move to tackle a persistent issue in their controllers. The company recently filed a patent for a magnetic joystick that employs a ‘smart fluid,’ possibly aiming to eliminate stick drift, a long-standing problem in gaming. This innovative joystick contains a ‘magnetorheological fluid’ (MRF), which adjusts its viscosity based on the strength of a magnetic field. Essentially, when a player moves the joystick with their thumb, the fluid thickens, creating resistance. Once the player releases the joystick, it returns to its original position smoothly.
This concept appears reminiscent of ‘Hall Effect’ sticks seen in some third-party peripherals that rely on magnets for movement detection. Due to the absence of connecting parts, these sticks are not susceptible to stick drift. The patent document states, “The speed of return of the operation element [the stick] to the initial position can be made faster in the controller using the MRF. In addition, it is possible to achieve both presentation of a feeling to the user by the operation element, and an operation of the operation element returning to the initial position.”
While the patent language is technical, it’s unclear whether the reference to “presentation of a feeling to the user” pertains solely to providing a natural resistance akin to traditional analog sticks or if it suggests customizable force feedback, similar to the PS5’s DualSense controller triggers. The big question remains: where will Nintendo apply this new joystick design? It might become a part of the successor to the Switch, potentially replacing the standard Joy-Cons. However, it’s worth noting that many gaming patents never materialize into actual products.
This move comes in response to Joy-Con drift issues that have plagued Nintendo since the launch of the Switch in 2017. Nintendo recently announced plans to repair all Joy-Con controllers suffering from drift in the EEA and UK, even if they’re out of warranty. Despite internal revisions, this problem persists, as reported by users with newly purchased Joy-Con controllers.

Now THIS is interesting. I hope they implement it into their new console.
