In this paper we present the results from a qualitative study exploring people's opinions and reactions to the possibility of emotion-aware adaptive web user interfaces, those which will have the capability to read users' emotions and adapt accordingly. The purpose of this work is to improve understanding of how people envision such emotion-aware interfaces may be a part of their computing experience, and to explore any concerns that people have relating to this technology. We expect that such information will be helpful for directing the development of new emotion-aware adaptive web interfaces.
