Overview
- Sony filed the patent with the World Intellectual Property Organization in November 2024 and the application was published by WIPO in May 2026, with media reports surfacing in mid‑June 2026.
- The document describes using a magneto‑viscoelastic elastomer and controllable magnets to vary a button or stick's hardness and elasticity by changing magnetic field strength.
- One detailed design would let a finger press into a button that then hardens around it to create a 'grab' sensation meant to simulate being seized or stuck in mud.
- Sony frames the system as real‑time, game‑driven feedback that could raise immersion, improve grip and offer new accessibility options, but the filing is exploratory and does not guarantee a consumer product.
- The work builds on PlayStation's DualSense haptics and has been linked by outlets to PlayStation's next‑generation planning, though technical, manufacturing and cost hurdles remain before this could appear in future hardware.
