Quality of Service (QoS) is a central characteristic of human-centric Ambient Intelligence (AmI) systems, since it has a strong relation to the degree of satisfaction with the services provided to users. Hence, AmI applications must be able to describe their QoS needs as well as capabilities so that the corresponding infrastructures can match the latter to the preferences of users. Current QoS specification techniques are concentrated on special domains like communication systems and do not address special aspects of the AmI field like high dynamics. In this paper we, elaborate the special AmI requirements posed to QoS specifications and describe an initial approach towards a solution.
