In-Cabin solutions include driver monitoring (DMS), occupant monitoring (OMS), and driver plus occupant monitoring systems (DOMS). Image sensors capture images of the driver using either ambient light, NIR light, or both depending on the overall system design. A Machine Vision processor analyzes the image data and determines the engagement level of the driver. The ADAS controller uses this input to make decisions.

OMS, which is similar to DMS, focuses on the occupants and not the driver. Child presence detection is the current use case. Seat belt detection and airbag adjustment are emerging OMS use cases. Another emerging trend is DOMS, a combination of driver and occupant monitoring using a single camera to capture images of the entire cabin as viewed centrally from either the rearview mirror or dashboard. These systems desire to combine driver state detection, occupant safety, and enabling social media applications.
