Introduction
Wearable computers, also known as wearables, are a class of electronic devices designed to be worn by a user, providing them with convenient access to information, communication, and various applications while on the move. These devices are typically integrated into clothing, accessories, or even implanted into the user’s body, making them easily accessible and unobtrusive. Wearable computers have become increasingly popular due to their ability to enhance productivity, improve health and fitness monitoring, and revolutionize user interactions with technology.
The Origins of Wearable Computers
The concept of wearable computers dates back to the 1960s when researchers began exploring the possibilities of integrating computing devices with clothing and accessories. However, it was not until the 1980s that the first wearable computer, known as the “Personal Electronic Aid to Maintenance” (PEAM), was developed by Edward O. Thorp and Claude Shannon. The PEAM was designed to help gamblers predict the outcome of roulette wheels.
