Latest rt-xr toy: shared virtual whiteboards

Since the sticky note idea now works, I thought that it would be fun to do a freehand version – a virtual whiteboard. It’s working pretty reasonably now. I placed a big whiteboard in my virtual office as you can see above to show how two or more occupants of the space can work together on a shared virtual whiteboard. The video below shows how this works.

The screen on the left is the desktop rt-xrViewer app, the screen on the left is the Mixed Reality Portal showing the Windows Mixed Reality rt-xrViewer app. The mouse is used to draw on the whiteboard in the desktop app (blue lines), motion controllers are used for the WMR app (red lines).

This also shows the new interaction rays. They sort of emanate from where the nose of the avatar should be.

They help give a sense of what the virtual occupants are doing. Otherwise, writing on the whiteboard seems a bit ghostly.

Whiteboards are actually proxy objects, driven from a special server that’s part of the SharingServer. The whiteboard itself is a completely dumb graphical asset. This makes it ideal for packaging as a Unity assetbundle and downloading at runtime rather than having to be built into the app. The required standard scripts included with rt-xrViewer are attached after a proxy object is instantiated.

This is the first time that proxy objects have supported interaction, opening the door to more interesting proxy objects in the future.
