Dr. Maria Chiara Leva:

As the Deputy mentioned, the trend is towards an autonomous system that does not need a supervisor to be present. In the interviews we conducted with some of the users, the perception was that there should be a go-to person, which does not mean a security officer but could instead mean a central presence with a sense of place who is connected with with other human beings. In an autonomous system, there is an absense of human beings. It still has an impact on how we perceive that system to be, such as safe or unsafe or trustworthy or untrustworthy, from the perspective of a user. The trend, however, is towards autonomy.
