Aging is associated with a progressive decline in health, resulting in increased medical care and costs. Mobile technology may facilitate health self-management, thus increasing the quality of care and reducing costs. Although the development of technology offers opportunities in monitoring the health of older adults, it is not clear whether these technologies allow older adults to manage their health data themselves. This paper presents a review of the literature on mobile health technologies for older adults, focusing on whether these technologies enable the visualization of monitored data and the self-reporting of additional information by the older adults. The systematic search considered studies published between 2009 and 2019 in five online databases. We screened 609 articles and identified 95 that met our inclusion and exclusion criteria. Smartphones and tablets are the most frequently reported technology for older adults to enter additional data to the one that is monitored automatically. The recorded information is displayed on the monitoring device and screens of external devices such as computers. Future designs of mobile health technology should allow older users to enter additional information and visualize data; this could enable them to understand their own data as well as improve their experience with technology.

A Software Product Line (SPL) is a portfolio of products that targets a particular domain. Feature Models are generally used for modeling domain knowledge including variability within SPLs. The Product Line Architecture (PLA) defines the structure that all potential products in the SPL share. Designing a good PLA is challenging since different products may require different characteristics, and it is difficult to achieve an acceptable trade-off. In this paper we apply Model-Driven Engineering techniques for systematizing the Domain Engineering stage to enable the automation of the Application Engineering stage. We use features to modularize architectural decisions and we encode them as model transformations that render the fragment of the product architecture that addresses the features. Then, we make the rationale explicit, and we enhance evolvability and incrementality diminishing design complexity. Product implementation is derived by means of generators analogously. We show our approach by developing a Meshing Tool SPL.
