Usability evaluation of a Virtual Assistive Companion

As a result of the great technological advances in the last decades, new solu-tions are emerging to avoid social isolation and to delay the institutionaliza-tion of older adults, as is the case of virtual assistants. This paper presents the usability evaluation of a Virtual Assistive Companion (VAC), the CaMeLi. The usability evaluation was based on a multi-method approach that comprises self-reported usability, usability reported by an evaluator and critical incidents registration. The usability tests were performed with 46 par-ticipants with an average age of 64 years. The results showed a good usabil-ity and satisfaction level, although usability reported by evaluators and criti-cal incidents registration suggest that some functionalities need to be im-proved in order to facilitate the VAC interaction and understandability.
