Smart glasses are a type of wearable computer that are designed to be worn on the head like a pair of regular glasses. They typically include a display that projects images into the user's field of view, a camera for capturing images and videos, and various sensors for tracking the user's head movements and eye gaze.
There are a variety of smart glasses available on the market, from those that are designed for general computing and entertainment purposes, to those that are specifically geared towards augmented reality (AR) applications. While most smart glasses are still in the early stages of development, there are already a number of companies and developers working on them, and a number of different product designs and prototypes have been unveiled.
One of the most notable examples of smart glasses is Google Glass, which was developed by Google and released in 2013. Google Glass was designed as a general-purpose computer, and was widely publicized as an example of the potential of wearable computing. However, the device was met with privacy concerns and was eventually discontinued.
A number of other companies are also working on smart glasses, including Microsoft, Amazon, Facebook, and Intel. While it remains to be seen how successful these products will be, it is clear that there is significant interest in the development of this technology.
