If you do not have an Oculus Rift DK2 VR headset, you can still enjoy AltspaceVR in 2D mode (though we think that the VR mode is more engaging). The controls are largely the same as described above, with one major addition: alt-toggle.
Press the left alt key on your keyboard to switch between Look Mode and Cursor Mode.
In Look Mode, your mouse will control where the camera is looking (this also corresponds to the avatar’s head motion).
In Cursor mode, you have access to the in game cursor to teleport, mouse over players, and interact with the action bar.
