Setup Guide

This documentation describes how to develop the Optical See-Through display app. It allows the user to see what is shown on the smart glasses screen while still being able to see through it (without the background of the camera). Image Tracker is supported with Optical See-Through display whereas all trackers are supported with Video See-Through display. Select 'None' at Wearable Type or refer to Unity Setup Guide to develop the Video See-Through display app.
