Licensing

FusionHub has two options for license protection:

Hardware dongle

License authentication using a hardware dongle; This is especially interesting for air-gapped installations that are not connected to the internet. As long as the dongle is inserted into a USB slot of the host system, FusionHub will run. Please note that for the Android (Quest 2 HMD) version of FusionHub, the GUI running on the streaming host is dongle protected, see more detailed information in the specific manual chapter.

Online license

License authentication using a software, online license; This makes sense for systems that are connected to the internet at least during the initial installation of FusionHub. The software checks its license status with our license server with following sequence:

1. Enter license key in configuration file. You receive your personal license key from us.

2. Send license key and machine code to server

3. Server checks if license is valid and returns response code, if it is valid

4. Copy the response code from the log and enter it in the config file to the ResponseKey parameter. Save the config file.

5. This allows FusionHub to run on this specific machine without reconnecting to the internet. One license unit will be subtracted from your license account. Please ask us for assitance if you’d like to move your license.

If your default configuration file config.json doesn't contain it already, add the LicenseInfo block as shown below. Enter your personal key you received from us as LicenseKey.

The optical system is the tracking reference, its pose is what is received by the visualization backend. The orientation of the IMU sensor is calibrated relative to the optical markers on the HMD. Therefore it is important to set up the tracking body or rigid body in the optical tracking software (DTrack, Motive etc.) in a way that its axes align with the optical axes of the head mounted display.
