Motion sickness is a growing barrier to existing technologies.
Vehicles are becoming spaces for living, working, and entertainment. But as EVs, autonomous driving, and in-vehicle screen use reshape the ride, motion sickness is becoming a bigger problem, not a smaller one.
Left unaddressed, it stands in the way of the future of mobility.
The answer was the driver all along.
Drivers rarely experience motion sickness. They naturally anticipate turning, braking, and accelerating before it happens, so their bodies stay in sync with the vehicle's motion. Passengers don't get the same advance notice, and that mismatch causes motion sickness.
PREACT was developed to bridge that gap. PREACT technology delivers preemptive cues just before the vehicle moves, giving passengers the same anticipatory advantage drivers have always had. The result is a technology grounded in 7+ years of research and built for integration into next-generation vehicle platforms.
One technology. Multiple ways to integrate.
PREACT technology scales to match your platform and goals, whether you're integrating into an existing seat design or developing something entirely new.
PREACT Active Seat
Actively adjusts seat posture in real time to align the body with vehicle motion, directly addressing the root cause of motion sickness.
PREACT Smart Seat
Leverages existing seat actuators and bolsters to dynamically support the body, assisting passengers in adapting to vehicle motion.
PREACT Haptic Seat
Provides intuitive haptic cues to inform passengers of upcoming vehicle motion, enabling anticipation with minimal hardware integration.
Research you can build on.
From University of Michigan research to real-world testing, PREACT technology is built on evidence, not assumptions.
