The band has an optical heart rate proctor, along with the gyro meter, 3-axis accelerometer, as well as the sensors for skin temperature, ambient light, galvanic skin response, and the capacitive touch (IDTechEx, 2014), as shown in the figure 2 in the Appendix. In addition, the ABI Research also suggests that the most promising area where the wearable technology is used most widely is the health and fitness in today’s market, and by 2017, this area alone can be ranged over 170 million of devices (Kurwa, et al. , 2014).

In this regard, there are some other examples, such as Adidas miCoach for athletes, adiSTAR Fusion used in shoes and sports, Zephyr’s Consumer HxM and BioHarness used for emergency responses, electromyography-sensor-based shirt by university students used to trail the data for exercises, and also the Utope’s fashionable Sporty Supaheroe used for fitness (a jacket with LED showing accelerator, phone calls, and 3D gyroscope) (Ranck, 2012). In the area of medical and E-health, it is suggested that the current market for medical devices in wearable technology is valued at $2 billion in 2011, which is predicted to be tripled by 2016 (TaylorWessing, 2012).

For example, the CGM (continuous glucose monitor) is the wearable medical device that is used by diabetes patients, where it provides alerts in advance about the increasing or lowering glucose levels in the patients, which help them to adopt a healthy lifestyle according to their disease (the device architecture is shown in appendix ad figure 3) (Facchinetti, et al. , 2013). In addition, the healthcare providers are using internet and wearable devices together to trail the patients’ symptoms and connect them to cure, such as medical patches, Tricorder, MEMS sensors, and Pulse Oximetry (Villasenor, 2014).

Apart from the medical, fitness, sports and lifestyle areas of wearable technology market, the optical devices in the area of computing and communication are becoming the mainstream product of the wearable technology market. For example, a recently launched device named, Google Glass, by the Google Inc. has computing and communication features with the style/glamour. Ranck, (2012) has stated that“…Google Glass has a camera that can collect and store images and video, and it also has a gyroscope, accelerometer, compass and microphones as well as Wi-Fi and Bluetooth…” (p.

10) (as shown in the figure 4 in appendix). It is the most recent innovative device that is also stylish and is priced only at $1500 and is launched for the consumer market.
