“…They found that most subjects liked the virtual character more than other modalities and performed significantly better in a task when guided by the virtual character. These findings are also supported by other results in [7]. In this study, Morandell et al compared a photograph with animated lips with a speech and text prompt.…”

We present the first experiment we conducted to evaluate the attention monitoring performance of Louise, following a Wizard of Oz method, during the interactions with a cohort of 8 elderly users in a day hospital environment. Louise is a new, semi-automatic prototype of an Embodied Conversational Agent (ECA), a virtual character interacting with users through social-like communication, adapted to the special needs of older adults with cognitive impairment; it is intended to ultimately provide assistance in their activities of daily living. We recorded and analyzed both videos of the conversation-like interactions and Louise's tracking data. In our experiment, Louise's attention estimation algorithm achieved about 80% accuracy; moreover, in almost all cases, the user's attention was successfully recaptured by Louise after a planned, experimenter-induced distraction. These results are in line with what was observed in previous experiments involving only younger adults, thus suggesting that attention measurement tools embedded in cognitive prostheses will not need to be adapted to elderly patients. Finally, to gain further insights on conversation management and provide evidence-based suggestions for future work, we performed an anthropological analysis of the whole experiment.

“…Among the former are devices for environmental monitoring and control [24]; smart walkers [20], which provide navigation assistance to older adults across public areas; and the smart kitchen environment Kochbot [1], which helps people with cooking tasks through spoken interactions. Virtual agents, which may be represented as people or characters, have been shown to enable an emotional relationship between people and assistive technologies [19,29,30]. Recently, virtual agents have been used in job interviews [6] and skill training [18], with associated studies to evaluate users' acceptance of virtual agents for teaching or training purposes [10,17].…”

This paper presents a study to determine users' attitudes toward smart devices. We conducted a web survey to elicit users' ratings for devices and combinations of tasks and devices; the results of this survey led to the development of a Recommender System (RS ) for smart devices for particular tasks. We investigated user-and item-based Collaborative Filters, and compared their performance with that of global and demographic RS baselines. We then developed a technique based on Principal Components Analysis to select a subset of the original survey questions that supports the prediction of users' ratings for device-task combinations. Our results show that the accuracy of an RS that asks only a small subset of the survey questions is similar to that of an RS that predicts users' answers to one survey question on the basis of their answers to all the other questions.

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.
