Abstract

Avatars are a common field of research for interfacing smart homes, especially for elderly people. The present study focuses on the usage of photo-realistic faces with different levels of movements (video, avatar and photo) as components of the graphical user interface (GUI) for Ambient Assisted Living (AAL) environments. Within a usability test, using the "Wizard of Oz" technique, these presentation modes were compared with a text and a voice only interface with users of the target groups: elderly people with (nMCI =12) and without (nMCI =12) Mild Cognitive Impairment (MCI). Results show that faces on the GUI were liked by both, elderly with and without cognitive restrictions. However, users' performance on executing tasks did not differ much between the different presentation modes.
