Another gimmick product that can behave as “e-health” systems for elderly care is smart clothing, which incorporates technological capabilities into existing wear. Nevertheless, smartphones also suffer from the constraints such as limited sensor quantities and locations. This means we do not need to fix sensor locations. Moreover, smartwatches are body mounted, with a standard, fixed location.
Smartwatches, a networked computer with an array of sensors, can realize continual connection to the skin to monitor physical signals. Functions that need skin contact monitoring are difficult to be realized by smartphones. However, the limited number of sensors and the locations where sensors are placed restricted smartphones’ functions.
For instance, smartphones are ubiquitously carried by people everywhere and every day besides the big enough screen of smartphones can behave as a great avenue for Human-Computer-Interaction (HCI). All of them have attractive advantages for delivering health information.
Finally, we discussed a series of considerations and future trends with regard to the construction of “smart clothing” system.Ĭurrently, smartwatch, smartphone and smart clothing are the mainstream products embedded wearable technologies with care functions. Since most elderly people suffer from age-related problems, some vital signs that can be monitored comfortably and continuously via existing techniques are also summarized.
Activity recognition not only helps ensure that sudden events (e.g., falls) will raise alarms but also functions as a feasible way to guide people’s activities so that they avoid dangerous behaviors. Positioning is the process of accurate localization and is particularly important for elderly people so that they can be found in a timely manner. These technologies are categorized into three types: indoor positioning, activity recognition and real time vital sign monitoring. In this article, we review state-of-the-art wearable technologies that can be used for elderly care. Recently, advances in wearable and sensor technologies have improved the prospects of these service systems for assisting elderly people.
With effective monitoring and alarm systems, the adverse effects of unpredictable events such as sudden illnesses, falls, and so on can be ameliorated to some extent. Generally, the elderly are more prone to health problems compared to other age groups.
