The trend towards increasing automation is not only having an effect upon the journey itself; it is also increasing its grip on the vehicle cabin. Assistance functions are increasingly turning drivers into passengers. The scope of potential secondary tasks and activities that are not related to driving is growing and this means that the driver and participating passengers can be distracted for extended periods of time. For driving safety reasons, the question of whether and in which situation the driver or other passengers would be able to assume control of the vehicle arises when dealing with cooperative or semi-automated driving. In order to answer this question, Fraunhofer IOSB has installed cameras in a vehicle cabin in order to be able to understand the respective movements and activities as well as take the overall cabin situation regarding the interaction with assistance systems into consideration with the aid of a robust body pose monitoring.
