Standard [[VR controller]]s ( | Standard [[VR controller]]s (for example Meta Quest controllers, Valve Index Controllers, PlayStation VR2 Sense controllers) typically include basic [[vibrotactile feedback]] (ERM or LRA). Some advanced controllers incorporate more nuanced effects, like the adaptive triggers and detailed haptics in the PS VR2 Sense controllers.<ref>Sony Interactive Entertainment. (n.d.).

[[Haptic gaming]] provides immersive experiences by allowing players to feel virtual environments and objects. Advanced systems like the [[Teslasuit]], [[bHaptics TactSuit]], and [[Dexmo]] exoskeleton gloves enable users to feel impacts, textures, and resistance in games.<ref>Pacchierotti, C., Sinclair, S., Solazzi, M., Frisoli, A., Hayward, V., & Prattichizzo, D.

The haptics industry faces challenges in [[haptic standardization]], with different devices using proprietary formats and protocols. Initiatives like the [[Haptics Industry Forum]] are working to establish standards for haptic content creation and playback across platforms.<ref>ISO/TC 159/SC 4 Ergonomics of human-system interaction.
