Wearable devices have increasingly become popular in recent years. Devices attached to users body remotely monitor his daily activities/health. Although some of these devices are pretty simple, others make use of an operating system to manage memory, resources, tasks, and any user interaction. Some of them were not initially designed and developed for this purpose, having a poor performance requiring the use of more resources or better hardware. This chapter presents a characterization of wearable devices considering the operating systems area. Some constraints of this context were designed to analyze the operating system's execution when inserted into a wearable device. Data presented at the end shows that there is a lack of performance in specific areas, letting to conclude that improvements should be made.
Chapter Preview

Operating systems and wearable devices can be analyzed in a separate way: the first one concerns about software specificities that control and manage the attached hardware. The second one is related to the context where the solution is applied. In this way, evaluate operating systems performance may be considered separately to the wearables context. However, it will lose precision, once the main area of applicability is not considered. Here the authors depict main related works that evaluate operating systems used by different fields. Conversely, in a second part, particularities related to wearable computing are also analyzed as a way to understand the main desired features when using an operating system inside this context.
