    Feasibility study of a robotic medication assistant for the elderly
    (Academia, 2011-01-17) Tiwari, P; Warren, J; Day, K; MacDonald, B; Jayawardena, C; Kuo, I.H; Igic, A; Datta, C
    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.

    Robots in older people’s homes to improve medication adherence and quality of life: a randomised cross-over trial
    (Springer, Cham, 2014-10-27) Broadbent, E; Peri, K; Kerse, N; Jayawardena, C; Kuo, I; Datta, C; MacDonald, B
    Healthcare robots are being developed to help older people maintain independence. This randomised cross-over trial aimed to investigate whether healthcare robots were acceptable and feasible and whether the robots could impact quality of life, depression and medication adherence. 29 older adults living in independent units within a retirement village were given robots in their homes for 6 weeks and had a non-robot 6-week control period, in a randomised order. The robots reminded people to take medication, provided memory games, entertainment, skype calls, and blood pressure measurement. The robots were found to be acceptable and feasible, and many participants described them as useful and as friends although not all comments were positive. There were relatively few problems with robot functions. The participants’ perceptions of the robots’ agency reduced over time. The robots had no significant impact on adherence, depression or quality of life. While the robots were feasible and acceptable, improvements in their reliability and functionality may increase their efficacy.

    Benefits and problems of health-care robots in aged care settings: A comparison trial
    (WILEY, 2015-09-13) Broadbent, E; Kerse, N; Peri, K; Robinson, H; Jayawardena, C; Kuo, T; Datta, C; Stafford, R; Butler, H; MacDonald, B. A; Robins, B
    Aim This study investigated whether multiple health-care robots could have any benefits or cause any problems in an aged care facility. Method Fifty-three residents and 53 staff participated in a non-randomised controlled trial over 12 weeks. Six robots provided entertainment, communication and health-monitoring functions in staff rooms and activity lounges. These settings were compared to control settings without robots. Results There were no significant differences between groups in resident or staff outcomes, except a significant increase in job satisfaction in the control group only. The intervention group perceived the robots had more agency and experience than the control group did. Perceived agency of the robots decreased over time in both groups. Overall, we received very mixed responses with positive, neutral and negative comments. Conclusions The robots had no major benefits or problems. Future research could give robots stronger operational roles, use more specific outcome measures, and perform cost–benefit analyses.

    RoboStudio: A visual programming environment for rapid authoring and customization of complex services on a personal service robot
    (IEEE, 2012-10-07) Datta, C; Jayawardena, C; Kuo, I. H; MacDonald, B. A
    Service robots for personal and domestic use are increasingly gaining momentum. Easy and efficient programming of such robots is an enormous research and commercial space that is beginning to be explored. In this paper, we present RoboStudio, a Visual Programming Environment (VPE) to program the interactive behavior of personal service robots. RoboStudio lies at the intersection of VPEs which aid in authoring the robot user interface and control logic. A novel contribution of this work is that it advances the research in authoring service applications on robotic platforms, specially for researchers who do development in decentralized multidisciplinary teams and validate their research goals through field trials. Furthermore, service robot programming environments is a novel area of research, particularly when it comes to expressing what the robot does in a declarative syntax.

    Design, implementation and field tests of a socially assistive robot for the elderly: Healthbot version 2
    (IEEE, 2012-06-24) Jayawardena, C; Kuo, I; Datta, C; Stafford, R.Q; Broadbent, E; MacDonald, B. A
    This paper presents the second version of a mobile service robot (HealthBot) designed for older people. The lessons learned from studies of the first version of the robot at a retirement village, and design decisions for the second version, are discussed. Technical requirements of field trials, a focus on cognitive human-robot interactions, the importance of working together in a multidisciplinary team, and the necessity for rapid iterative development suggested a new software framework. The features of new framework are discussed and implementation details are presented. Details of field trials and user acceptance results are presented. Results are promising for older-user acceptance of the robot.
