Managing Sensor Data in Ambient Assisted Living
Nugent, C.D.,Galway, L.,Chen, L.,Donnelly, M.P.,Mcclean, S.I.,Zhang, S.,Scotney, B.W.,Parr, G. Korean Institute of Information Scientists and Eng 2011 Journal of Computing Science and Engineering Vol.5 No.3
The use of technology within the home has gained wide spread acceptance as one possible approach to be used in addressing the challenges of an ageing society. A number of rudimentary assistive solutions are now being deployed in real settings but with the introduction of these technology-orientated services come a number of challenges, which to date are still largely unsolved. At a fundamental level, the management and processing of the large quantities of data generated from multiple sensors is recognised as one of the most significant challenges. This paper aims to present an overview of the types of sensor technologies used within Ambient Assisted Living. Subsequently, through presentation of a series of case studies, the paper will demonstrate how the practical integration of multiple sources of sensor data can be used to improve the overall concept and applications of Ambient Assisted Living.
From Compliance to Context - Advancing Assistive Technology Capabilities for Medication Management

It is a well known fact that patients do not always comply with their prescribed medication regimes. This may be partly attributed to the complexity surrounding the compliance issue itself. Issues relating to compliance involve a number of stakeholders in the supply-to-intake chain of medication and in addition are complicated further by the manner in which the medication is prescribed, delivered and taken. This paper presents an innovative electromechanical compliance aid which can be used within a person"s home and can be monitored remotely via Internet based technologies. The technology developed has been evaluated in 4 pilot sites and initial results have shown its usage to improve patient compliance levels and also to reduce the workload of stakeholders involved in home based support of medication management. The paper concludes with a vision of consolidating the proposed technical solution with advances in context prediction to further improve home based medication management services.

HomeTL: A Tool Set to Support Service Monitoring Development
Alberto Rugnone,Chris Nugent,Mark Donnelly,Enrico Vicaro,Cristiano Paggetti 동국대학교 정보융합기술원 2008 International Journal of Assistive Robotics and Sy Vol.9 No.1
The integration of intelligent technology into the home environment has become recognized as a means of providing higher levels of autonomy and independence for the aging population. Within this technology domain, an area of particular interest is in the development of the services offering the facility to monitor and react to contextual scenarios based on the information sampled from sensorised environments. To facilitate the definition of the set of rules upon which the monitoring service can react, healthcare professionals are consulted to define the specifications of scenarios and to profile user specific needs. This activity also requires technical expertise to design, implement and refine the set of rules which guide the context under which the technology operates. As a result healthcare professionals are unable to fully participate in the development of the service model. This has resulted in an emerging barrier between the coherence of the healthcare professional descriptions and the understanding of technology providers. The current work proposes a set of tools to reduce this barrier and involve the healthcare professionals in the development process. Initial results from a user evaluation suggest that such tools hold the potential for real world adoption in the process of designing and interpreting the set of rules used to govern an intelligent environment.
Assessment of Bradykinesia, Akinesia and Rigidity Using a Home-based Assessment Tool
L. Cunningham,C. Nugent,G. Moore,D. Finlay,D. Craig 동국대학교 정보융합기술원 2009 International Journal of Assistive Robotics and Sy Vol.10 No.4
An increase in the prevalence of age related diseases such as Parkinson's Disease (PD) and the increasingly aging population has created a need for appropriate health and social care services for the elderly and disabled. PD requires close monitoring and regular assessment. In order to be assessed and monitored, people are usually required to attend a clinic or hospital. In this study a home-based assessment tool, which collects information on people’s hand and finger movements, has been developed and evaluated. The tool collects data on the time taken to make a series of movements, the speed at which the movements are made and the path that is taken for each movement. Through the use of this tool movement difficulties such as bradykinesia, akinesia and rigidity could be identified within the home environment. Such an approach has the potential to decrease the number of clinic/hospital visits a person with PD requires. It could also assist with making the current, somewhat subjective, methods of PD assessment become more objective. If used over a long period of time, for example, daily or weekly, it could help identify how effective or otherwise a person's medication is. This would be achieved by the tool collecting data on a regular basis in order to establish what is considered to be ‘normal’ results for that particular person. So for example, a pattern may emerge over a few months that each time a particular participant is ‘off’ they take the same or similar length of time to use the tool. It could be suggested that the length of time the participant took to use the tool when ‘off’ during those months was their ‘normal’ result for their ‘off’ state. If, after a period of time, the results collected seemed ‘abnormal’ for that person it could indicate that a visit to the clinician is needed to identify if the medication needs changed. The developed tool was evaluated by twenty participants. Half of the participants had been diagnosed with PD and the other half were a control group without the disease. Within each group there were a mix of participants who were computer literate and those who had no experience of using computers. Results following evaluation of the tool indicated that the control group were able to conduct assessments using the tool in a time that was significantly shorter than that taken by the PD group (p = 0.034). This in turn suggests that such tools have the ability to assist with enabling more objective assessment of PD.
