Robot-era project: Preliminary results on the system usability

The European project Robot-Era is an ambitious integrated project (FP7-ICT-2011.5.4), which objective is the development of advanced robotic services, integrated in intelligent environments, to provide independent living to older people. In order to guarantee the matching of the users� need and the demands, two loops of experimentation were conceived, in realistic and real setting. The aim of the paper is to described the methods applied and the main results coming from the first experimental loop, concerning the degree of usability of the interfaces and provide guidelines for testing socially assistive robots with older people. � Springer International Publishing Switzerland 2015.
