Shed Light on the Path of Human-Machine Interaction in Autonomous Vehicles: Where Did We Come from? Part II, Search Strategy, Findings and Perspectives

As vehicles have become more complicated, Human-Machine Interaction (HMI) is becoming crucial. Nowadays, HMI is a substantial element in autonomous vehicles (AVs). Numerous studies are lately being published regarding significant parameters of AVs which can affect HMI. Hence, it is imperative to have a comprehensive prospect, to improve people's acceptance of AVs. In AVs, the driver's role will change to a passenger, however, it can be switched in some special situations. This work is divided in two parts: the first study has mapped from 299 papers in this area and found the most impressive concerns of people in using AVs. Various researchers’ approach has shown a dramatic shift from physical parameters to psycho-emotional ones; as results, trust and comfort are ranked first and second in the reviewed articles, respectively. The second part is dedicated to the explanation of methodology, the synthesis of findings and the perspectives about the future scenarios. Key findings and some insightful observations on the future of this approach are discussed in this section of the article. As a conclusion, we developed a novel model named 3p consisting of personal, psycho-emotional, and physical parameters, which states the current trend of momentous features affecting HMI in AVs.
