“…Given the positive effect of trust in the teacher on student performance [101], our data might help to improve patient education through e-learning by the use of avatars as tutors. Research in the field of Alzheimer’s disease has already shown that patients suffering from neurological diseases might benefit from interaction with avatars [102]. Our results suggest that this finding could also hold true in the population of PD patients.…”

Parkinson’s disease (PD) is a neurodegenerative disease that affects the motor system and cognitive and behavioral functions. Due to these impairments, PD patients also have problems in using the computer. However, using computers and the Internet could help these patients to overcome social isolation and enhance information search. Specifically, avatars (defined as virtual representations of humans) are increasingly used in online environments to enhance human-computer interaction by simulating face-to-face interaction. Our laboratory experiment investigated how PD patients behave in a trust game played with human and avatar counterparts, and we compared this behavior to the behavior of age, income, education and gender matched healthy controls. The results of our study show that PD patients trust avatar faces significantly more than human faces. Moreover, there was no significant difference between initial trust of PD patients and healthy controls in avatar faces, while PD patients trusted human faces significantly less than healthy controls. Our data suggests that PD patients’ interaction with avatars may constitute an effective way of communication in situations in which trust is required (e.g., a physician recommends intake of medication). We discuss the implications of these results for several areas of human-computer interaction and neurological research.

Embodied conversational agents (ECAs) are virtual characters using verbal and non-verbal communication for Human-machine interaction. The aim of our research is to create an ECA-based user interface for assistive technologies targeting older adults with cognitive impairment. Our design methodology is a co-design living lab approach, collecting design guidelines through questionnaires, focus groups and user trials.In this paper, we report on the results of the first phase of this iterative design process. We developed Louise, a semi-automatic ECA prototype that aims to compensate, through attention monitoring, for a user's attentional disorders by performing autonomous prompting, i.e., calling the user to regain his or her attention in case he or she got distracted. We evaluated the performance of Louise with a group of experts in assistive technologies and collected their feedback. Louise's simple attention estimator is more than 80% accurate. The system got quite positive reviews from users.

“…[2007] proposed to enhance one of the elderly main leisure activities by integrating an interactive avatar with the television. Carrasco et al [2008] adapted this technology to aid in the therapy of elderly suffering from Alzheimer's. The study was conducted with twenty-one people with Alzheimer's disease and the results showed that the participants were able to interact naturally with the avatar and understood the information conveyed by the avatar.…”

Studies in the field of human-computer interaction have demonstrated a significant impact of avatars and virtual environments on users' interaction experiences and behaviors. However, most of these studies are focused on the young users. With an aging population and more virtual environments built for the elderly, it is important to investigate the types of avatars elderly users prefer and hence provide them with a richer interaction experience through the use of avatars as virtual representations of themselves. In our exploratory study, 24 seniors aged 55 years and above evaluated 20 custom-created avatars. Results showed that the elderly participants were unable to identify with the avatars. However, the results showed a strong trust towards child avatars and an attraction towards animal and object avatars, which indicates a different form of identification or empathy. The paper concludes with discussion of avatar design for the elderly users.CR Categories: H5.m. Information interfaces and presentation (e.g., HCI): Miscellaneous.
