“…More specifically, the measure of attentional capabilities and processing speed through cognitive assessment tests can bring useful information for a personalization of such a user interface. In [12], the authors have proposed to adapt the prompting modalities to the person's cognitive and perceptive abilities.…”

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.

“…If dementias are usually associated with memory impairment, they also cause executive and attentional disorders [12], which come in addition to the diminution of attentional capabilities observed in normal aging [9]. These specific constraints call for a user-centric design approach.…”

“…The goal of our project is to rely on video game technologies (game engine, 3D animation and Kinect) to create an ECA, called Louise, that is adapted to the special needs of older adults with cognitive impairment. Older adults with dementia have executive and attentional disorders [2], which come in addition to the diminution of attentional capabilities observed in normal aging [3]. Our team, hosted at the Broca Hospital in Paris, in the LUSAGE living lab [4], observed in many assistive technology trials that people with dementia often lose track of what they are doing and their attention needs to be redirected towards the task.…”

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.

“…Individuals with MCI receive prompts or cues from their spouses or family members to guide them to complete or initiate the IADL accurately [7]. Innovative assistive technologies have been developed to assist the person with cognitive impairment with ADLs around the home and improving the quality of life of elderly and decreasing caregiver burden [14]. Assistive technologies such as smart homes use different prompts to guide senior to complete a task independently.…”

We present a design and preliminary evaluation of novel visual guidance of a remote assistive system for the elderly to find hidden objects in a kitchen. Our system has two essential functions; 1) to update a list and corresponding location information of objects concealed in a shelf with at all times, and 2) to display images and texts about the objects on the corresponding area of the door of the shelf. We aim to realize assistive visual guidance to elderly for overcoming the deficits of initiation, planning, attention and memory deficits while performing kitchen-based activities of daily living such as finding items for cooking. In this study, we focus on hidden objects because there is an increased possibility for the elderly with cognitive impairments to forget where and what the object is due to the non-visibility. The paper shows the prototype system that uses RFID and projection technology. We conducted a user study with twelve elderly participants to evaluate the usability of the system using the System Usability Scale (SUS). Additionally, we also investigate the acceptability of the system by applying the Unified Theory of Acceptance and Use of Technology (UTAUT). The results demonstrate that the elderly participants found the system useful and easy to use. Finally, we conclude that a remote assistive system can be used to assist elderly to storing and retrieving objects from cabinet and shelves during a kitchen task but need more studies to make the system more efficient and effective.
