Sony Interactive Entertainment has patented a novel controller design featuring buttons capable of altering their tactile resistance on the fly. The technology, detailed in a patent application initially filed in November 2024 and published in May of this year, would allow button hardness to adjust based on in-game events or player preferences.
This adaptive resistance is reportedly achieved through a magneto-viscoelastic elastomer, a material that can change its stiffness when influenced by a variable magnetic field. This magnetic field could be controlled by the game itself, with its strength fluctuating according to the action displayed on screen. The patent also mentions the potential use of fluid-filled membranes as an alternative method to achieve a similar outcome.
Further concepts within the patent describe a design where a player's finger could press into a button, with the button then hardening around it. While the exact application of this feature is not explicitly detailed, it could be used to simulate scenarios such as an enemy's grip or movement through difficult terrain like mud.
This development echoes Sony's innovation with the PlayStation 5's DualSense controller, which introduced advanced haptic feedback and adaptive triggers. The DualSense's adaptive triggers, for instance, can modify the resistance a player feels when squeezing, allowing for in-game actions like drawing a bowstring or firing different weapons to have distinct physical sensations.
While the implementation of adjustable button hardness is still theoretical, Sony has acknowledged ongoing development of its next-generation PlayStation console. Should this patent be granted, it could become a significant feature in an updated DualSense controller for a future PlayStation model. Current industry speculation suggests a potential release for the PlayStation 6 around 2028 or 2029, providing ample time for such advanced technology to be integrated into a production unit.
