The most advanced smart glasses on the market are the Google Glass and the Microsoft HoloLens. They both offer a wealth of features that allow users to interact with their environment in a more natural way.
The Google Glass is equipped with a camera that can take photos and record videos, as well as an array of sensors that allow it to track head movements and eye gaze. This enables users to control the device hands-free, making it ideal for use in situations where using a traditional smartphone would be impractical. The device also has built-in Wi-Fi and Bluetooth connectivity, allowing it to connect to the internet and other devices wirelessly.
The Microsoft HoloLens is similarly equipped with cameras and sensors, but also includes an array of microphones that enable it to detect sound directionality. This allows users to hear holograms from specific directions, making them appear more realistic. The HoloLens also features inside-out tracking, which means it doesn't require any external markers or cameras to track its position in space - something that makes it much more portable than other virtual reality headsets on the market.
