Next-Gen PS6 Controllers Could Feature Magnetic Joysticks To Eliminate Stick Drift
Story Highlight
- A new patent published by Sony suggests next-gen PlayStation controllers could use magnetic joysticks.
- These joysticks would use magnetic sensors, possibly TMR, to eliminate stick drift issues.
- The improved design ensures high-precision detection of tilt and press operations while preventing unwanted rotation.
Even though magnetic options exist, Sony and Xbox have continued to use traditional potentiometer-based analog joysticks in their console controllers over the years. These joysticks often develop stick drift with repeated use, requiring fixing and replacement over time.
However, we have found a new Sony patent that suggests the company might finally switch to magnetic joysticks for its next-gen PS6 controllers. The document explores innovative non-contact operating sticks that rely on magnetic sensors, like TMR or other types.
Sony aims to improve magnetic joysticks by enhancing their sensitivity, allowing high-precision inputs even after prolonged use.
The patent achieves this refinement by forming engaging protrusions on the stick's supported portion that fit into grooves in the housing. It constrains rotation about the axis and ensures that tilt forces are accurately detected.
‘Movement of the operating stick can be detected with high precision even under prolonged use. [...] when a user applies a force to the operating stick to tilt [...], that force is prevented from being consumed by the rotation of the operating stick, and as a result, operability of the operating stick can be improved.’
Why it matters: The improved magnetic joystick design aims to ensure long-term tilt and press accuracy while preventing stick drift in next-gen controllers. We can expect PS6 controllers to be more durable, precise, and long-lasting compared to the current ones.

The patent called 'OPERATING STICK ASSEMBLY AND INPUT DEVICE' discusses magnetic joysticks that also feature a spring-based return mechanism designed to reset the stick to its neutral position.
The joysticks also feature a cylindrical biasing structure that applies lateral force to stabilize stick position. This improves sensor precision and prevents rattling damage caused over time.
Sony argues that current joysticks used in controllers are not long-lasting because they don't remain high-precision after repeated use, as issues like stick drift become rampant.
Hall-effect and other magnetic joysticks are better alternatives, but are mostly available only as third-party replacement kits. However, that might change in the PS6 generation
As a non-contact sensor, for example, a magnetic sensor is utilized. [...] The tilting operation sensor may also be a TMR sensor (Tunnel Magneto-Resistance Sensor), which is another type of magnetic sensor.

Regardless, Sony has previously explored controllers with magnetic parts and easily swappable buttons; this patent seems to be a more grounded version of that idea.
Do you think the PS6 controllers will switch to magnetic joysticks to end stick drift for good, or will Sony stick to the traditional potentiometer-based analog joysticks? Let us know your thoughts in the comments below.
