  In the presence of interaction conflicts, user trust in automation plays an
important role in accepting intelligent environments such as smart homes. In
this paper, a factorial research design is employed to investigate and compare
the single and joint effects of Level of Automation (LoA), Frequency of
Automated responses (FoA), and Conflict Intensity (CI) on human trust and
acceptance of automation in the context of smart homes. To study these effects,
we conducted web-based experiments to gather data from 324 online participants
who experienced the system through a 3D simulation of a smart home. The
findings show that the level and frequency of automation had an impact on user
trust in smart environments. Furthermore, the results demonstrate that the
users' acceptance of automated smart environments decreased in the presence of
automation failures and interaction conflicts.
