Nuitrack Device API allows you to enumerate and activate compatible depth sensors and run Nuitrack with a selected depth sensor. Please note that you can use several sensors only if you run several Nuitrack instances (1 sensor = 1 process).
In Examples, you can find two samples that show how to use Nuitrack Device API:
There's also nuitrack_device_api_sample in the Nuitrack runtime that allows you to select and activate a specific sensor by its serial number and run Nuitrack with this sensor. You can find this sample in %NUITRACK_HOME%/bin on Windows or in /usr/bin/ on Linux.
Note: If you want to run Nuitrack with several depth sensors, we recommend you to use the sensors of the same type, for example, 2 RealSense D435. You can see the list of all supported sensors and platforms at our website.
See an example of Nuitrack integration in our tutorial Integrating Nuitrack with your application (Windows/Ubuntu).
