Abstract

In the past century, there has been a significant rise in human life expectancy in almost all regions of the world. In order to improve the well-being and quality of life with specific attention for ageing, different organizations support innovative digitally-enabled solutions for older people. Personal mobile devices, such as smartphones and wearables, provide a great opportunity to monitor and evaluate any health condition that the elderly subject may have. Wearables require batteries and the device's power requirements drive the battery weight, size, and type. The battery weight is an important concern in wearable devices because it may affect negatively to its ergonomic. Therefore, to reduce the battery weight is of the utmost importance. One way to reduce the battery weight is to reduce the battery consumption of the wearable device. However, a reduction on battery consumption could negatively affect to other concerns of the system, like the relative error or the response time. So, it is important to have a trade-off between battery saving and these other concerns. Self-adaptation approaches like Dynamic Software Product Lines (DSPL) are suitable for this purpose as they can adapt systems taking into account contextual information and the current state of the device. In this work, we study the integration of a wearable platform, Smart Cane, with a DSPL, Tanit. Our experiments show it is possible to have a trade-off between the different concerns of the system, so we can save energy and at the same time to have an acceptable relative error. With a relative error lower than 1%, we can elongate the life of the Smart Cane more than 8 hours.
