A new in-car system is designed to assess passengers’ physical and emotional states, weighing key cues such as fatigue or sleep level, body posture in the cabin, and whether they’re using mobile devices like smartphones.

The idea is straightforward: the system will automatically pick the optimal moment to trigger an alarm for the driver or a passenger so they wake up before the vehicle reaches its final stop.

This becomes especially relevant for upcoming fully autonomous vehicles, where the driver can rest while the autopilot takes over. Timed well, a gentle prompt before arrival can feel natural and keep the ride calm, all while aiming to enhance comfort and safety.
