Use python to run script under pupil_src/shared_module:
$ python3 hololens_server.py
Get the IP address of your host computer, copy it into your Hololens Apps. Make sure Hololens and your host computer are in the same network.
Now you could start your tracking functions in the Hololens App
Notice that if you are using Windows system, you probably have to specify the network interface by changing the TCP_IP parameter in the hololens_server.py
