show human-adapted (and in some sense human-like) emotional behavior. The other side of the coin could be that human users might tend to attribute to a system showing human-like emotional reactions the full complexity of their own emotions. This may result in the user being sometimes worried about the system, disappointed, or frustrated when s/he realizes that the system is not a human. Or perhaps this danger will simply not exist, as humans will become used to interacting with affective systems and get to know them (including their limitations). In any case, we as designers should always make clear what is "inside the system" in order to avoid promoting false illusions in the users. This is not in contradiction with the fact of trying to make emerge not only humancentered, but also human-like emotional interactions in HCI.
