Slide 1


Image of Smart Glasses detailing main features:

  • Infra-red projector

  • Infra-red camera

  • The arms house a processor capable of driving the displays at 30 frames per second

  • Depth Camera: a depth camera measures the distance to nearby objects, a little like radar. A pattern of infra-red points are projected forwards and a camera looks for changes in these points. These changes reveal the 3D structure of nearby objects.

  • The smart-glasses comprise a camera to sense the environment and a digital display to show an enhanced view. The battery and processing unit are connected via a cable and not shown here.

  • Transparent Displays: The lenses are Organic Light Emitting Diodes (OLED) that show an enhanced image to the wearer while appearing transparent to everyone else. This allows the eyes to be seen which is important for social interaction.
