bHaptics On-Device AI Audio-to-Haptic Engine is software that adds haptic feedback to PC games that were never built for it. Running in the background, it captures game audio at the operating system level and uses an in-house AI model to classify individual sound effects such as gunshots, reloads, explosions, and hits in real time. Each recognized event triggers a haptic pattern authored for that sound on TactSuit, bHaptics' haptic vest. Earlier audio-driven systems map loudness and frequency to vibration, so everything feels alike. Classifying events instead lets each one carry a distinct pattern. A dedicated “none” class keeps the vest silent when nothing meaningful occurs. Classification runs on the device, using the integrated GPU where available, with minimal effect on the frame rate of the game running alongside. No developer integration is required, and total latency from sound to vibration on a Bluetooth-connected TactSuit stays under 50 ms.
