Today, there are many companies which offer wearable devices with different capabilities. In health and fitness wearable measure different parameters like heart rate, perspiration, and oxygen levels of the human body. Due to advancement in image processing and machine learning techniques, it has become possible to detect drowsiness which is used in a smart driver assistance system.
Some additional capabilities of wearable devices are more ordinary but provide very useful information For example, wearable devices could tell if you have your jacket on in the car. This could be helpful in keeping remind that you have your jacket or not. If your wristband can measure perspiration levels that could also be used as a data point for adjusting both temperature and humidity.
The above examples could all use a smartphone as the central control for delivering these capabilities, but is that really the most efficient approach? Would it be better if the Internet of Things (IoT) devices could communicate directly? We certainly don’t want to use our smartphone for every information wearable devices wishes to convey? Perhaps a better model is that the smartphone can help set up the modes of operation you want to support, as well as the privacy level you wish to enforce. Once the communication “strategy” is in place, all the devices can communicate as desired.
Wearable devices could be allowed to automatically connect to devices around the home too. We can have a preferred lighting level while watching TV from a particular location. We could turn on the TV and our wearable device could help adjust the lighting level from the connected LED lights within the room. An intelligent house might even support automatically blocking light from windows to avoid displeasure while watching TV. Even the backlighting on the LCD TV screen could be adjusted and all settings optimized for saving energy, as well as creating the most favourable viewing experience. All these interactions could be done automatically using wearable with IoT.
In this challenging time, using IoT technology, we can measure the body temperature of surrounding people. The basic symptom of COVID-19 is fever and high body temperature. Using smart wearable, we can measure our body temperature as well as the body temperature of other surrounding people. These are the great device which can protect us from virus-like COVID-19.
Wearable technology can also improve patient management efficiency in hospitals. Researchers hope to use wearable technology for the early detection of health imbalances. Wireless communication in wearable techniques enables researchers to design a new breed of point-of-care (POC) diagnostic device. For example, garments integrated with wearable solutions, such as commercial portable sensors and devices in the emergency medical services (EMS), emergency room (ER) or intensive care unit (ICU) environments, have facilitated the continuous monitoring of risks that endanger patient lives. The system enables detection of patient health-state parameters (heart rate, breathing rate, body temperature, blood oxygen saturation, position, activity and posture) and environmental variables (external temperature, presence of toxic gases, and heat flux passing through the garments) to process data and remotely transmits useful information to healthcare providers.
Developing wearable devices and algorithms to monitor mental conditions is a relatively new domain. Some wearable devices are equipped with sensors that can detect human physiology statuses, such as heartbeat, blood pressure, body temperature, or other complex vital signs (e.g. electrocardiograms). Using these signals, new systems can be developed to monitor mental conditions. Stress detection is the most common application of such systems.
