Sony filed a patent that could solve the persistent stick drift problem plaguing DualSense controllers. This development matters because it promises a hardware-level fix that outlasts the wear and tear of traditional potentiometers. Buyers waiting for the next PlayStation console should watch this technology closely.
New patent describes non-contact magnetic sensors to eliminate stick drift
The patent, titled 'Operating Stick and Assembly and Input Device,' appeared on July 2nd. It describes a controller design for the upcoming PS6 era that replaces mechanical contact with non-contact magnetic sensors. This shift aims to eliminate the physical degradation that causes input errors over time.
The design uses engaging protrusions that slot into grooves with a spring-based return system. A cylindrical biasing structure stabilizes the magnetic field to ensure consistent stick centering. Sony claims this setup allows for high-precision detection even after prolonged use.
The patent also notes that the magnetic approach prevents force from being consumed during stick rotation. This mechanical efficiency improves overall operability for the user.

It remains unclear if this technology will ship with the PS6 console or sell as a pro-level upgrade. Patents often describe ideas that may prove impractical or never become reality. The final implementation details will only be known when Sony releases the actual hardware.
