ABSTRACT
As far as interaction is concerned Ambient Intelligence (AmI) research emphasizes the need of natural and friendly interfaces for accessing services provided by the environment. In this paper we present the result of an experimental study aiming at understanding whether Embodied Conversational Agents (ECAs) and Social Robots may improve the naturalness and effectiveness of interaction by playing different roles when acting as interface between users and smart environment services. Results obtained so far show that ECAs seem to have a better evaluation than robots for information related tasks. On the other side, Social Robots are preferred for welcoming people and for guiding them in the smart environment, due to their possibility to move and to the perceived sense of presence. Moreover, the robot seems to elicit a more positive evaluation in terms of user experience.

Social robots and ECAs for accessing smart environments services
Recommendations
Social robots as mediators between users and smart environments
IUI '07: Proceedings of the 12th international conference on Intelligent user interfacesIn this paper we propose the use of a social robot as mediator between the user and a smart environment. Since the speech is considered one of the more natural and immediate input channel in human-robot interaction we discuss the importance of ...
Wizard of Oz studies — why and how
Current approaches to the development of natural language dialogue systems are discussed, and it is claimed that they do not sufficiently consider the unique qualities of man-machine interaction as distinct from general human discourse. It is concluded ...
Interaction Studies with Social Robots
ICMI '15: Proceedings of the 2015 ACM on International Conference on Multimodal InteractionOver the past 10 years we have seen worldwide an immense growth of research and development into companion robots. Those are robots that fulfil particular tasks, but do so in a socially acceptable manner. The companionship aspect reflects the repeated ...
