Tutorials are one of the most fundamental means of conveying knowledge. Ideally, tutorials not only describe each step with text or via audio narration but show it as well using photos or animation. In most cases, tutorial authors capture media from handheld mobile devices to import into these documents, but increasingly they use wearable devices as well. Here we explore the use of head-mounted...

BACKGROUND Recent epidemiological evidence indicates that, on average, people are sedentary for approximately 7.7 hours per day. There are deleterious effects of prolonged sedentary behavior that are separate from participation in physical activity and include increased risk of weight gain, cancer, metabolic syndrome, diabetes, and heart disease. Previous trials have used wearable devices to in...

With the rapid growth and increased life expectancy of the world’s population, the prevalence of chronic disorders such as Parkinson’s disease (PD) is also increasing. This challenges the current healthcare system in terms of cost and resources reallocation. An emerging approach facilitated by a new technological platform, called the Internet of Things, and the introduction of wearable devices ...

The majority of available wearable devices require communication with Internet servers for data analysis and storage, and rely on a paired smartphone to enable secure communication. However, wearable devices are mostly equipped with WiFi network interfaces, enabling direct communication with the Internet. Secure communication protocols should then run on these wearables itself, yet it is not cl...

This paper describes the development of a low-cost health monitoring system for the elderly at home. The system integrates ZigBee mesh network, cellular network, ubiquitous and mobile computing, hardware miniaturization and various sensor technologies. The centerpieces are wearable devices that are capable of detecting accidental falls, monitoring heart rate, tracking locations, etc. Wearable d...

Sensor devices integrating embedded processors, low-power, lowbandwidth radios, and a modest amount of storage have the potential to enhance emergency medical care. Wearable vital sign sensors can track patient status and location, while simultaneously operating as active tags. We introduce CodeBlue, a wireless infrastructure intended for deployment in emergency medical care, integrating low-po...

match, it was the first time that a computer Go program was able to beat a 9-dan professional without handicaps. This was simultaneously met by reactions of enthusiasm and horror regarding artificial intelligence. In particular, the fear that doctors will be replaced by artificial intelligence is rampant in among doctors. The role of WATSON, designed by IBM for application in the medical area, ...

Surface Electromyography (EMG) is an important tool for medical diagnosis, rehabilitation and sports biomechanics. While it is usually used to perform recording of data under laboratory conditions, wearable sensors have enabled also mobile recording of dynamic movements. This has led to feedback applications which require real-time processing of the EMG data on mobile devices. This paper presen...

This special issue of the Journal of Medical and Biological Engineering highlights the field of advanced bioelectronics and bioinformatics. Several papers were considered for this special issue, including those on bioelectronics in wearable and implantable medical devices, such as sensors, and bioinformatics in healthcare, brain cognition, and various neural pathologies. Many investigators cont...

As the market and related industry for wearable electronics dramatically expands, there are continuous and strong demands for flexible and stretchable devices to be seamlessly integrated with soft and curvilinear human skin or clothes. However, the mechanical mismatch between the rigid conventional electronics and the soft human body causes many problems. Therefore, various prospective nanomate...
