    Management of complex medication regimens by older people poses a significant challenge wherein use of information technology could play a role in improving clinical efficacy and safety of treatment. The use of computing devices, however, presents a special challenge to older people given their physical and cognitive limitations. Robotic platforms show promise for extending the functionality of the user interface to make personalized interaction engaging and empowering, and for proactively reaching out to older users to support their healthcare delivery. We believe that a robot combining a touch screen and voice based interface could offer an effective platform to meet these requirements. This paper reports on a feasibility study of such a system for helping older people with their medications. We exposed 10 relatively independent residents of an aged care facility to our robot running a medication reminding application while they took their medications. The interaction was followed by a questionnaire and structured interview to elicit their opinions and feedback. We found the application to be well received as all users could successfully complete the session, and most subjects found it easy to use, appropriately designed and felt confident using it. A number of technical errors were uncovered, and the results suggest opportunities to refine the equipment and dialog design to provide a better robotic medication assistant.

    Improved robot attitudes and emotions at a retirement home after meeting a robot
    (IEEE, 2010-09-13) Stafford, R. Q; Broadbent, E; Jayawardena, C; Unger, U; Kuo, I. H; Igic, A; Wong, R; Kerse, N; Watson, C; MacDonald, B. A
    This study investigated whether attitudes and emotions towards robots predicted acceptance of a healthcare robot in a retirement village population. Residents (n = 32) and staff (n = 21) at a retirement village interacted with a robot for approximately 30 minutes. Prior to meeting the robot, participants had their heart rate and blood pressure measured. The robot greeted the participants, assisted them in taking their vital signs, performed a hydration reminder, told a joke, played a music video, and asked some questions about falls and medication management. Participants were given two questionnaires; one before and one after interacting with the robot. Measures included in both questionnaires were the Robot Attitude Scale (RAS) and the Positive and Negative Affect Schedule (PANAS). After using the robot, participants rated the overall quality of the robot interaction. Both residents and staff reported more favourable attitudes (p <; .05) and decreases in negative affect (p <; .05) towards the robot after meeting it, compared with before meeting it. Pre-interaction emotions and robot attitudes, combined with post-interaction changes in emotions and robot attitudes, were highly predictive of participants' robot evaluations (R = .88, p <; .05). The results suggest both pre-interaction emotions and attitudes towards robots, as well as experience with the robot, are important areas to monitor and address in influencing acceptance of healthcare robots in retirement village residents and staff. The results support an active cognition model that incorporates a feedback loop based on re-evaluation after experience.

    Deployment of a service robot to help older people
    (IEEE, 2010-10-18) Jayawardena, C; Kuo, I. H; Unger, U; Igic, A; Wong, R; Watson, C.I; Stafford, R.Q; Broadbent, E; Tiwari, P; Warren, J; Sohn, J; MacDonald, B.A
    This paper presents the first version of a mobile service robot designed for older people. Six service application modules were developed with the key objective being successful interaction between the robot and the older people. A series of trials were conducted in an independent living facility at a retirement village, with the participation of 32 residents and 21 staff. In this paper, challenges of deploying the robot and lessons learned are discussed. Results show that the robot could successfully interact with people and gain their acceptance.
