Google Glass
The glasses with a small screen and camera that were meant to become a computer for the face.
Google Glass showed information and photos in front of the eye and was controlled by voice and touch. The product raised debate about privacy because the wearer could film without others knowing.
The consumer version was withdrawn in 2015, but the technology lives on in industrial versions and in later smart glasses.
Materials: Titanium, plastic, prism and display
Manufacture: Developed by Google and sold to developers from 2013.
