Wearable technology
Wearable technology encompasses electronic devices that are worn on the body, including items like fitness trackers, smartwatches, and smart glasses. These gadgets are designed to enhance daily living by monitoring health metrics, delivering notifications from smartphones, and even providing hands-free access to various functions. Fitness trackers, such as the Fitbit, are particularly popular as they track physical activity, heart rates, and sleep patterns, often syncing this data with companion apps for user analysis. Smartwatches offer functionalities similar to smartphones, but in a wrist-worn format, allowing for calls, messages, and other app interactions.
Smart glasses represent a more advanced form of wearable technology, projecting information directly into the user’s line of sight and capable of hands-free operation. However, despite their potential benefits, the growth of wearable technology faces challenges, such as high costs and concerns over privacy and data security. Many devices collect and transmit personal information, raising fears about identity theft and unauthorized tracking. Looking ahead, the future of wearable technology may involve increasingly sophisticated smart clothing that can monitor vital signs, detect health issues, and possibly even administer medical treatments directly. This evolution highlights the delicate balance between technological advancement and the need for privacy and security in an interconnected world.
Wearable technology
Wearable technology refers to any electronic device worn on the body. Wrist wear, shoes, and glasses are some of the most common forms of this technology. The variety of wearable technology available to consumers is growing rapidly. Many experts think that wearable technology has the potential to improve people's everyday lives. However, others warn that the large amount of personal data wearable technology collects could easily be obtained and used for criminal activity.
Types of Wearable Technology
Fitness trackers, like the Fitbit, are the most common form of wearable technology. These devices are normally worn on the wrist or clipped on clothing. However, some devices are paired with or built inside shoes. Many function as powerful pedometers and heart-rate monitors. Some even help users track periods of rest, calories burned, and the quality of their sleep. Most fitness trackers work with a smartphone application or computer program to deliver the collected information.
Another type of wearable technology is a smartwatch, which has functions similar to a smartphone. Smartwatches mimic the appearance of traditional watches, featuring digital screens that display time and additional information. Most smartwatches pair with a user’s smartphone, allowing the user to see messages or calls on the watch that the phone has received. Some smartwatches are even capable of taking pictures, sending messages, and making phone calls.
While smartwatches are limited by their small screen size, smart glasses bypass screen size entirely. Instead, they use a translucent material placed in front of one or both eyes to project a screen directly into the user’s field of vision. Most smart glasses function by tracking the hand and eye movements of the users and syncing their movements with the projected display. The glasses can function as a global positioning system (GPS), access the internet, and take hands-free videos and pictures. Some can also pair with a user’s smartphone, providing many of the same functions as a smartwatch.
Other forms of wearable technology are much less common. A number of clothing brands offer smart shirts targeted toward high-level athletes. These shirts provide incredibly detailed biometric information about the wearer through a variety of sensors attached to the fabric. Other less common forms of wearable technology include rings programmed for functions such as changing television channels, controlling door locks, and interacting with smartphones; belts that track the wearers' waistlines; and shoes that sync with a GPS and vibrate in the direction the GPS instructs wearers to turn.
Limitations of Wearable Technology
The popularity of wearable technology is limited by a variety of factors. First among these is price. Some of these devices are considered cutting-edge technology and are accompanied by a high price tag. While many smartwatches and fitness trackers became more widely accessible and affordable in the 2010s, technologies like smart glasses remained expensive, often putting the item well out of range of the budget of average consumers. Because of this, many consumers dismissed some types of wearable technology as unnecessary luxury items.
Another limitation of wearable technology is that many experts believe the proliferation of wearable technology severely damages the average person’s expectation of privacy. When digital security firm Symantec tested common forms of wearable technology, it found that virtually all commercially available products could be used to track and record the location of the wearers without their consent. A significant percentage of these devices also transmitted a variety of personal information without encryption, making that information particularly easy to steal.
Experts warn that even information that is transmitted with encryption is only as safe as the network on which it is stored, and that keeping large amounts of personal information on a home computer may be unsafe. They worry that the increased use of wearable technology puts users at greater risk of identity theft, extortion, and stalking. They also worry that devices with discrete cameras, such as smart glasses and smartwatches, will make it impossible to avoid being recorded in public.
Future of Wearable Technology
High-end wearable technology already has the ability to collect a large amount of data about individual users. The future of wearable technology is in expanding the ways this data can be stored and used. Experts think that in the future, most smart clothing will be able to determine wearers' locations, read their vital signs and stress levels, and record their daily activity. Smart clothing may even have the capacity to alert wearers if they begin to show early signs of a disease, or if they need more exercise, sleep, or relaxation. In people with existing health conditions, the wearable technology could automatically call an ambulance if the wearer has collapsed. Experts think that someday, wearable technology may even be able to administer medicine directly through the wearer’s skin.
