"A Sony patent published on July 2 describes a controller design using non-contact magnetic sensors to improve analog stick accuracy and durability."
Patent Aims to Eliminate Stick Drift
The patent, titled "Operating Stick and Assembly and Input Device," outlines a design that uses "engaging protrusions" that fit into grooves. This mechanism is intended to reduce force consumption during rotation, directly targeting the common issue of stick drift.
Potential Application in Future PlayStation Hardware
This design could be used in a future PlayStation controller, potentially the PS6. The shift to non-contact magnetic sensors would represent a significant durability upgrade over current potentiometer-based sticks, which are prone to wear and drift over time.
