Software and Hardware Requirements and Trade-Offs in Operating Systems for Wearables: A Tool to Improve Devices’ Performance

Abstract

Wearable device requirements currently vary from soft to hard real-time constraints. Frequently, hardware improvements are a way to speed-up the global performance of a solution. However, changing some parts or the whole hardware may increase device complexity, raising the costs and leading to development delays of products or research prototypes. This paper focuses on software improvements, presenting a tool designed to create different versions of operating systems (OSs) fitting the specifications of wearable devices projects. Authors have developed a software tool allowing the end-user to craft a new OS in just a few steps. In order to validate the generated OS, an original wearable prototype for mining environments is outlined. Resulting data presented here allows for measuring the actual impact an OS has in different variables of a solution. Finally, the analysis also allows for evaluating the performance impact associated with each hardware part. Results suggest the viability of using the proposed solution when searching for performance improvements on wearables.

Benefits of Home-Based Solutions for Diagnosis and Treatment of Acute Coronary Syndromes on Health Care Costs: A Systematic Review

“…In Europe, massive progress has been achieved since the early 1990s when the European Commission started to promote the adoption of eHealth practices in the member states. The first eHealth Action plan covered the period between 2004-2012 and has been replaced by the second eHealth Action plan 2012-2020 [68] and complemented by the Digital Agenda for Europe, the Innovation Union initiative and the Digital Single Market Strategy. Monitoring the levels of key cardiac biomarkers from blood samples has a great potential to become a popular home-based solutions due to: (i) low degree of invasiveness, does not require implantable sensor or surgical procedure, (ii) easy implementation in current clinical practice both in the primary and secondary care setting and (iii) potential anticipation of health deterioration triggering early intervention.…”

Field Research Cooperative Wearable Systems: Challenges in Requirements, Design and Validation

“…This is important to understand the most relevant variables when proposing novel tools and architectures. This paper analyzes hardware and software project practices and the usual methodologies employed during the design process of wearable systems [34].…”

“…In this section, we perform a case-study to validate the presented processes. This system is based on a prototype proposed by Amorim et al [34], displayed in Figure 2. We do not propose any change in the hardware configuration since our objective here is not to validate the device alone, but the application of multiple devices.…”

“…This validation follows the reviewed and presented methods. For this matter, we develop a platform based on a previously verified platform, proposed by Amorim et al [34]. This process focuses on the design of a novel system architecture using validated devices to the detriment of novel device architecture.…”
