Nintendo files patent for smart fluid joysticks which could stop stick drift
Nintendo has filed a patent for a new controller which would include a ‘smart fluid’ in its joysticks, in a change that may help stop stick drift — a problem which has affected Nintendo Switch owners since the release of the console in 2017.
As VGC reports, the patent describes the utilization of “magnetorheological fluid” — a type of smart fluid that can change in viscosity when subjected to a magnetic field. In this context, this can seemingly be used to cause resistance when a user moves a joystick.
Most importantly, as VGC points out, the process described in the patent sounds similar to Hall effect joysticks which are already on the market. These detect movement by using magnets, but have no connecting parts, so stick drift can never occur.
Over the years, many Nintendo Switch owners have reported running into stick drift issues — where their Joy-Con controllers have begun to detect incorrect joystick inputs over time — so if this new patent has been filed with the intention of fixing this problem for good, it’d be a huge step forward for Nintendo fans.

“By changing the viscosity periodically between the first viscosity state and the second viscosity state, it is possible to provide the user with an unprecedented feeling on the operation element and an unprecedented operation feeling thereof, while ensuring movement of the original element autonomously returning to the initial position,” the patent reads.
It’s worth keeping in mind, however, that a
