Abstract

One consequence of ongoing discoveries and successes related to the prevention and treatment of illnesses and diseases is an aging population. With this comes an increase in chronic illnesses which will place a significant strain on existing healthcare resources. One proposed solution is the introduction of assistive technologies such as telecare, to allow patients to live and be monitored at home. Much of this technology can be enabled by pervasive technologies. As a part of the process of implementing this assistive technology, an assessment is carried out by social workers. This assessment aims to elicit user requirements regarding a telecare system, based upon which an appropriate system is proposed and implemented. Unfortunately, there can often be a mismatch between a user's perceptions and expectations, and the system which is installed, leading to non-acceptance. This paper proposes and demonstrates how the PSABI model can be used as a part of this process. The factors that compose the model are shown to be effective at capturing information relevant to the monitoring aspects of telecare. The model itself is also simulated using VenSim, with a series of system designs assessed to see which meets the requirements of its users; and ultimately their acceptance of the technology.
