INFO

CAVR is a general, future-proof design that exports multiple types of context information that are sent over anetwork interface. This design works for basically all VR-HMDs, with the help of community-supported tools.

DESIGN & IMPLEMENTATION

The theoretical design and used software to implement this design:

INSTALL

First clone this repository:

git clone https://github.com/Charles-Derek/Context-Aware-VR.git

To build the Context-Extraction system, navigate to the third-party directory under vr_tracking:

cd Context-Aware-VR/vr_tracking/third-party

Make the three main install scripts executable:

chmod +x packages.sh cppzmq.sh mqtt.sh

First we install all necessary packages, check if any errors occur!

./packages.sh

Next, we install the ZMQ library, check if any errors occur!

./cppzmq.sh

Finally, we install the MQTT library, check if any errors occur!

./mqtt.sh

All necessary software should be installed and we can test the Context-Extraction system. To build it, use the CMakeLists.txt under Context-Aware-VR/vr_tracking/CMakeLists.txt

To test the system, don't forget to first install Steam & SteamVR, once SteamVR detects the HMD correctly the system should work.

The subscriber that shows the visualization is located in vr_subscriber called subscriber.py. For MQTT you need to run an additional instance broker.py

Future implimentations include a web interface for the subscriber to run on a remote machine using Docker with usb passthrough to the host machine and motion capture system.
