First, please follow the Hardware Setup Guide that came with your Looking Glass. If it can't be found, download a copy here:
Download and install HoloPlay Service to start working with holograms.
Interaction Accessory Pack
Interaction Accessory Pack owners must also install Leap Motion drivers. Please download and install the V4 (Orion) version of the Desktop SDK.
This is only available on Windows. Mac users may experimentally use V2 drivers, though tracking quality is worse, and many apps in the library are not compatible.
Test your Setup
This simple test can be run to ensure that hardware is connected and software is installed and configured:
When the above button is pressed, the Looking Glass should show a 3D image like below. To close this image, move your mouse over and click anywhere on the image.
The image should appear 3D. If it appears with diagonal lines (as on the right), there is an error. Please retry the setup steps above to ensure it is properly configured. If that doesn't fix it, try troubleshooting HoloPlay Service.
Once the setup is complete, go back to the User Guide welcome page to begin working with the Looking Glass.
