BACKGROUND: Wearable devices have attracted much attention from the market in recent years for their fitness monitoring and other health-related metrics; however, the accuracy of fitness tracking results still plays a major role in health promotion. OBJECTIVE: The aim of this study was to evaluate the accuracy of a host of latest wearable devices in measuring fitness-related indicators under various seminatural activities. METHODS: A total of 44 healthy subjects were recruited, and each subject was asked to simultaneously wear 6 devices (Apple Watch 2, Samsung Gear S3, Jawbone Up3, Fitbit Surge, Huawei Talk Band B3, and Xiaomi Mi Band 2) and 2 smartphone apps (Dongdong and Ledongli) to measure five major health indicators (heart rate, number of steps, distance, energy consumption, and sleep duration) under various activity states (resting, walking, running, cycling, and sleeping), which were then compared with the gold standard (manual measurements of the heart rate, number of steps, distance, and sleep, and energy consumption through oxygen consumption) and calculated to determine their respective mean absolute percentage errors (MAPEs)...

INTRODUCTION: The use of wearable activity monitors has seen rapid growth; however, the mode and intensity of exercise could affect the validity of heart rate (HR) and caloric (energy) expenditure (EE) readings. There is a lack of data regarding the validity of wearable activity monitors during graded cycling regimen and a standard resistance exercise. The present study determined the validity of eight monitors for HR compared with an ECG and seven monitors for EE compared with a metabolic analyzer during graded cycling and resistance exercise...

Despite widespread understanding of the benefits of physical activity, many adults in the United States do not meet recommended exercise guidelines. Burgeoning technologies, including wearable fitness trackers (e.g., Fitbit, Apple watch), bring new opportunities to influence physical activity by encouraging users to track and share physical activity data and compete against their peers. However, research has not explored the social processes that mediate the relationship between the use of wearable fitness trackers and intention to exercise...

Maximal heart rate (HRmax) is a fundamental measure used in exercise prescription. The Apple Watch™ measures heart rate yet the validity and inter-device variability of the device for measuring HRmax are unknown. Fifteen participants completed a maximal oxygen uptake test while wearing an Apple Watch™ on each wrist. Criterion HRmax was measured using a Polar T31™ chest strap. There were good to very good correlations between the watches and criterion (left: r = 0.87 [90%CI: 0.67 to 0.95]; right: r = 0...

Due to recent advancements and appealing applications, the purchase rate of smart devices is increasing at a higher rate. Parallely, the security related threats and attacks are also increasing at a greater ratio on these devices. As a result, a considerable number of attacks have been noted in the recent past. To resist these attacks, many password-based authentication schemes are proposed. However, most of these schemes are not screen size independent; whereas, smart devices come in different sizes. Specifically, they are not suitable for miniature smart devices due to the small screen size and/or lack of full sized keyboards...

As humans, we are born with no knowledge of odour. Our sense of smell is linked directly to the limbic system, the emotional part of our brain responsible for memory and behaviour, and therefore, our individual sense of smell is based purely on life's deep experiences and impressions. The roots of "Aromatherapy" can be traced back more than 3,500 years, to a time when essential oils were first recorded in human history for their therapeutic and medicinal properties. However, in the 21st century, it remains one of the most controversial complementary therapies applied in medicine because of its pseudoscience connotations and limited available data on health benefits, despite the importance of smell on human health...

BACKGROUND: Physical activity tracking wearable devices have emerged as an increasingly popular method for consumers to assess their daily activity and calories expended. However, whether these wearable devices are valid at different levels of exercise intensity is unknown. OBJECTIVE: The objective of this study was to examine heart rate (HR) and energy expenditure (EE) validity of 3 popular wrist-worn activity monitors at different exercise intensities. METHODS: A total of 62 participants (females: 58%, 36/62; nonwhite: 47% [13/62 Hispanic, 8/62 Asian, 7/62 black/ African American, 1/62 other]) wore the Apple Watch, Fitbit Charge HR, and Garmin Forerunner 225...

REVIEW
Colin Camerer, Dean Mobbs
Real behaviors are binding consequential commitments to a course of action, such as harming another person, buying an Apple watch, or fleeing from danger. Cognitive scientists are generally interested in the psychological and neural processes that cause such real behavior. However, for practical reasons, many scientific studies measure behavior using only hypothetical or imagined stimuli. Generalizing from such studies to real behavior implicitly assumes that the processes underlying the two types of behavior are similar...

Using augmented input might be an effective means for supplementing spoken language for children with autism who have difficulties following spoken directives. This study aimed to (a) explore whether JIT-delivered scene cues (photos, video clips) via the Apple Watch(®) enable children with autism to carry out directives they were unable to implement with speech alone, and (b) test the feasibility of the Apple Watch(®) (with a focus on display size). Results indicated that the hierarchical JIT supports enabled five children with autism to carry out the majority of directives...

Electronic laboratory notebooks (ELNs) will probably replace paper laboratory notebooks (PLNs) in academic research due to their advantages in data recording, sharing and security. Despite several reports describing technical characteristics of ELNs and their advantages over PLNs, no study has directly tested ELN performance among researchers. In addition, the usage of tablet-based devices or wearable technology as ELN complements has never been explored in the field. To implement an ELN in our biomedical research institute, here we first present a technical comparison of six ELNs using 42 parameters...

Leslee Thompson
Something big is happening in healthcare. It's not the new Apple Watch, 3D printing or the advent of personalized medicine. It's people power. And, it is starting to shake up the very foundation on which healthcare systems around the world have been built. Healthcare professionals and hospitals are iconic features on a healthcare landscape that has been purpose-built with castles, moats and defence artillery. Turf protection, often under the guise of "patient protection," has become so ingrained in the way things are that few recognize what it has become...
