  Wearable devices are a trending topic in both commercial and academic areas.
Increasing demand for innovation has led to increased research and new
products, addressing new challenges and creating profitable opportunities.
However, despite a number of reviews and surveys on wearable computing, a study
outlining how this area has recently evolved, which provides a broad and
objective view of the main topics addressed by scientists, is lacking. The
systematic review of literature presented in this paper investigates recent
trends in wearable computing studies, taking into account a set of constraints
applied to relevant studies over a window of ten years. The extracted articles
were considered as a means to extract valuable information, creating a useful
data set to represent the current status. Results of this study faithfully
portray evolving interests in wearable devices. The analysis conducted here
involving studies made over the past ten years allows evaluation of the areas,
research focus, and technologies that are currently at the forefront of
wearable device development. Conclusions presented in this review aim to assist
scientists to better perceive recent demand trends and how wearable technology
can further evolve. Finally, this study should assist in outlining the next
steps in current and future development.
