Dementia is currently a growing epidemic, bringing forth severe health, social, and economic strains. As an alternative to pharmacological measures, current research supports the effectiveness of using cognitive training interventions to slow the decline of or even improve brain functioning in persons with dementia. However, implementing and sustaining these interventions on a long-term basis can be challenging as they demand considerable resources and people. Our research focuses on investigating the potential use of robotic assistants to allow for these interventions to become more accessible to users and caregivers. Namely, the aim of our work is to develop socially assistive robots that can provide cognitive and social stimulation for persons with dementia. In this paper, we study the social interaction attributes of the human-like robot, Brian 2.0, during a one-on-one personcentered cognitively stimulating activity to determine if the robot is capable of minimizing task-induced stress by providing assistance, encouragement, and celebration, while adapting its behavior to a user state during the course of the activity. Our preliminary study shows that the social intelligence of Brian 2.0 is effective in engaging individuals in a cognitively stimulating game while minimizing stress during gameplay.

“…Our research focuses on the second category of smart home systems, namely on the development of assistive technologies for the elderly in order to assist them with ADLs to promote aging-in-place (Nejat & Ficocelli, 2008;Chan, Nejat, & Chen, 2011;McColl, Chan, & Nejat, 2012). ADLs can be defined as (Lawton & Brody, 1969;Rogers, Meyer, Walker, & Fisk, 1998):…”

As the world's elderly population drastically increases, aging-related cognitive impairments have become one of the biggest healthcare concerns. In this paper, we present the design of an assistive kitchen system consisting of a user interface with two-way speech communication and an automated cabinet system to help promote aging-in-place. The assistive kitchen system incorporates a cognitive assistance feature that helps the user in overcoming initiation, planning, attention, and memory deficits, while performing kitchen-based activities of daily living (ADLs) such as storing and retrieving items, and obtaining recipes for meal preparation. This feature works synchronously with the automated kitchen cabinet to directly provide the location of an item to a user, bring the item in closer reach and also prompt the user to retrieve the item. An initial prototype of the assistive kitchen system has been developed and performance testing has been conducted. The testing has shown high success rates for users' retrieving and storing specified kitchen items. A small scale study was also conducted measuring the acceptance and use of the proposed system by older adults. The results show promise for the further development and use of the system for the outlined kitchen ADLs.

“…The goal of our research is to advance knowledge in cognitive/social interventions for elderly individuals suffering from cognitive impairments via the development of robotic technology [6], [7]. We aim to design humanlike, socially assistive robots capable of providing cognitive assistance and social interaction in self-maintenance (i.e., eating, dressing, and grooming) and activities of daily living (i.e., cognitively and socially stimulating leisure activities).…”
