develop with proxy for vr hardware

Can I develop for VR hardware while not connected to VR hardware? I'm starting with the VR examples that come with 5.3.

I find it cumbersome to need to physically connect to an Oculus to move forward with my development. I would like to use some sort of proxy for head tracking, hand controller tracking and buttons. I feel like it should be possible to use WASD keys or similar for tracking input, and mouse (Fire1, etc) for button input.

Btw, I am enjoying the new articles about virtual reality that came with examples for version 5.3. Thanks Unity Devs!
