Wrist computers are fully automated wearable gadgets or smartwatches designed to offer the best solutions and open the growth in the field of technology. Carrying computer systems everywhere is unworkable. With the help of wearable devices, the user can avail game playing facility, digital time telling, performing calculations, as well as operation of mobile devices, can be done by connecting the wrist wearable to your smartphone via Bluetooth.
The first wearable computer was designed in the 16 century, which was taken to an advanced level by Steve Mann, to solve complex algorithms, implement various tasks rather than only displaying time and perform mere chores.
However the development of wearable computers came into recognition in the 2010s, by interfacing WPAN(Wireless Personal Area Network) and WBAN(Wireless Body Area Network) which gave rise to development in intervention treatment, defense systems, and self-health checkup systems as well.
Sony manufactured the first wearable device that needed to be connected with a smartphone(android), accessible from a particular distance, acting as a notification tool as well. The existence of wearable computers proceeded with many other brands and organizations working on the same goal.
Design and Development strategies
Wrist wearables include a 3D interface, pulse sensor, accelerometer, pressure and temperature sensor, camera, flashlight along with LED display. The wrist wearables also provide information about the wearer, a GPS system.
The user’s intent is kept in mind that includes offering a life of ease. Along with a humidity sensor, steps measurement, memory chip, and voltage regulator, the wrist wearables can be carried in a bog or worn, keeping the activities on all day long.
Applications of Wrist wearable devices
The wrist wearable computers were designed to assist the soldiers during wars and fights. It was first introduced in the US Army in 1989 including land warrior programs. The Indian-based military project called F-INSAS consists of largely developed wrist wearable computers for more specific targets.
Elderly support- Wrist wearables provide supports to the elderly by helping them with disabilities and guiding them through the right directions. It acts as the third eye for elderly people.
The wearable devices are designed for children especially with colorful bands and attractive UI. The main purpose of these types of advanced wrist wearables is to protect the children from human threats and call in case of emergency.
Healthcare monitoring system-The wrist wearables help in heart rate monitoring, spot illness, help you to maintain a balance between workout and rest. Fitness trackers are commonly used by 90 percent of the individual to monitor and maintain fitness.
Challenges in wrist computers:
With the surge in technology, wrist wearables are also prone to many vulnerabilities. Challenges like security issues, regulation unacceptance, ethical issues, wrist wearables were mostly seen in the health and fitness sector, in the form of smartwatches or fitness band to check heart rate, steps per day, barometers, GPS, Wifi, and Bluetooth enabled techniques for easier access to the user.
No doubt technology is making the life of humans easier but is also harmful in some ways. With the increase in wearable computers like Bluetooth headphones, human-to-human interaction is in the diminishing stage, causing social and cultural issues. The development of wrist wearable like google glass break also created many privacy issues, due to its potential to record and store anything without the user’s awareness.
Although the internal issues, the wrist computers also face some technical problems such as battery issues, data management, security issues, improper software architecture as well.
Wearable computers are found in many forms. For instance, smartwatches(wrist-mounted computers) or smartphones sometimes strapped to arms, wearable computers in the form of helmets for safety, and sensory recognition.
The wrist wearables are designed to perform tasks easily even in remote areas, however, the only flaw is that the display screen is comparatively smaller than normal computes, making it challenging for the reader to read and perform their task.
