Screenshots and Videos

^ The software connects the virtual world (AR/VR) and physical worlds (Arduino) through data channels.

^ Using a virtual slider (top) to control a physical robot (bottom) [Video]

^ A smartphone user seeing the virtual shapes drawn by the Hololens user [Video 2nd half].

^ Left: A physical knob controlling a virtual shape (green) & sound [Video]. Right: Kicking around a virtual element [Video].

Features

  • Connect Unity3D to Arduino electronics

    • Arduino to Unity: Use physical sensors to control Unity objects / effects

    • Unity to Arduino: Use Unity virtual objects to control physical actuators / robots

  • Connect multiple AR / VR devices together

    • Currently you can connect multiple Hololens devices together and a PC.

    • All users can see the shared 3D objects and manipulate them.

    • (Under development) You can port this to other MRTK-compatible devices, like smartphones and Oculus / VR headsets.

  • Features for creating 3D worlds: Use the library menus to create new objects (3D models from the Objects library; 2D images from the Images library). Move/scale/edit objects between multiple users. Add object effects tied to sensor data. (Coming soon: Load OBJ models and images from a web address)

  • Features for connecting sensors to virtual objects: Sensor values can influence custom effects (ex: generate sounds based on sensors). Sensor values can influence transformations (ex: objects change their scale, rotation, color based on sensor values)

  • Features for creating presentations: Save/load scenes you've created, and create step-by-step presentations. Virtual laser pointers and drawings for annotating the scenes.

  • Summary of features: see features list

Downloading and Using

  • First please ensure you are looking at the latest repository. The latest repository is found at: [https://github.com/iuli4n/AR-CYBS-UnityArduinoMultiplayerXR]

  • Hardware requirements:

    • This project is meant to run on Windows computer with multiplayer AR/VR with Arduino connections.
    • You don't actually need an Arduino or Hololenses
    • (Optional: It has been used on iOS Unity; and on Android mobile and on iOS mobile, in multiplayer mode together with a Windows PC and Hololens users; it can probably be ported on other devices compatible with MRTK)
  • Software requirements

  • Installation: Follow the documentation for instructions on downloading and using.

Features Under Development

  • Websocket connections to other wifi electronics (ex: ESP32)

  • Deployment on other platforms: Android, Oculus VR

Known Bugs

  • Clicking with the right hand doesn't work well unless the wrist is angled. Use left hand instead.

  • Moving/closing the in-world menus needs to be synchronized across all users

  • Collider for drawings has some issues

  • Effects set on objects do not transfer if those objects are saved/loaded across scenes
