Abstract:
Safe driving is mandatory for an advanced driver assistance system (ADAS). We consider that the adequacy
and safety of the driver assistance services can be monitored by observing drivers’ positive and negative
emotions, since, if they find a hazardous situation, he/she has a negative emotion, ”surprised” or ”dangerous.”
If they feel to be assisted by the system, they will have a positive emotion. In order to analyze requirements
for the ADAS, we propose a multi-layered scenario analysis (MuLSA). MuLSA is developed by integrating a
customer journey map and a service blueprint with the context of a scenario. A customer journey map consists
of a scenario; as the customer’s experiences, as well as a customer’s emotions toward the services. The service
blueprint represents a customer’s journey, as well as a mechanism of the services. Thus, MuLSA consists of
a driver’s journey, his/her emotions, the mechanism of services, as well as the context of the service. In order
to prioritize requi
rements for the safety of a future ADAS, we have observed driver emotions with regard
to hazardous scenarios with MuLSA. This paper shows the results of the observation, and we discuss the
effectiveness of MuLSA.
