— Increasingly, applications of technology are being developed to provide care to elderly and vulnerable people living alone. This paper looks at using sensors to monitor a person's wellbeing. The paper attempts to recognise and distinguish falling, sitting and walking activities from accelerometer data. Fast Fourier Transformation (FFT) is used to extract(More)
This is the final report on the PAPA (Distributed Ada Debugging) project (MoD Contract number: NUW72D/1090). The project's objective was to determine the requirements of a tool to support the testing and debugging of a distributed system implemented in Ada and produce a specification for such a tool. The work was to support the SMCS project being conducted(More)
— In this paper, we describe our experience of designing a telecare product for the elderly. This is a collaborative project involving Passivsystems Ltd and the Centre for Healthcare Modelling and Informatics at the University of Portsmouth. The research aims at adapting Passivsystems' existing in-home hub so that it is capable of providing a telecare(More)
The disciplinary status of health informatics remains unclear. Is it an art or a science? Does it have a body of theory? A survey was devised for UK academics that teach or research health informatics. Forty-six responses were received, twenty-five from the target group (representing between a quarter and a third of the population of interest). Health(More)
eHealth investments from developed countries to developing countries are expected to follow the emerging trend of eHealth for meeting global health problems. However, eHealth industry from developed countries will need to learn to make this impending venture a 'win-win' situation with profitable return on investments. This short paper highlights some of(More)
Based on qualitative research, we developed the theoretical construct "clinician information usage propensity" as a hypothetical indicator of attitudes and behaviour towards clinical information and systems. We devised a survey to validate the construct and had 146 responses. Principal components analysis extracted four factors accounting for 47.2% of the(More)
Debugging distributed programs is more difficult than debugging sequential ones. This paper describes a means of making this easier by presenting the user with a "time line" view of an Ada program. Each time line shows the successive states of an Ada task as easily recognisable symbols on a time axis. Communication and sychronisation between tasks is shown(More)
This paper discusses the role that information, particularly information collected and used near to the patient, can play in the delivery of healthcare services. We define what we mean by "near the patient" and review many of the ways in which information is currently collected, stored and shared. We identify what technological and other factors have(More)
