Camboard - The "travelling mate" (for VR)

Filming in VR implies a whole new conception of the movie "stage".
While standard 2D (or "Aquarium 3D") is limited to shoot at a rectangular zone, VR filming implies shooting "in the action", the scene being "all around".
This way of shooting video requires an evolution of standard filmmaking, but will be really great :
- For members of the audience in next VR-equipped theaters (an high-end VR helmet in the back of each seat, allowing UNIQUE movie watching if VR and in 3D for each spectator).
- For film studios companies, because :
1 - They could rise the price of the movies (but please shoot @ 120Hz !)
2 - Spectators could go see the same film many times for instance because a friend has told them that they missed a scene while watching at something else at a specific time !

"Camboard" is the first step in the direction of my conception of next-gen VR filmmaking : Piloting a kind of "terrestrial drone" which holds the VR camera amongst actors.

This first prototype is manual, and so is equipped with 2 systems :

- Pull : You pull the camboard with a (transparent) wire (you can attach it to your belt for instance, to have your arms free).
It follows you wherever you go (but take car, running with it can be dangerous for the camera ;-)
It's not as good but cheaper than a €1600 "following drone"...
- Push : You "drive" the camboard with your selfie stick (instead of shooting another duck-face selfie with it ;-), "connected" to the rectangular "selfie stick holder" on the board.
You can make smooth turn and the camera slides along while keeping perfectly horizontal, more stable than filming a the end of a selfie stick.

Here's a demo of it (push mode) :

The (obvious) limitation of this system is that human action is required.
And unlike for "2D movies", VR cameras are also filming...the cameraman himself !
So camboard could be really great for shooting in VR if it was radio-controlled.
It could then be called a "smartboard".

Right now, this is only a daydream, but if I were working @ Google, I could be part of a team to make it a reality :

- Adding a Bluetooth-controlled servo-motor to the three wheels, allowing "translation" of the board in any direction with analog speed control using the left stick
- Right analog stick would control camera rotation (to move VR "center" of the movie (which can be overridden by VR "looking"))
- Standard "cross" controller (up/down/left/right) could motor-control the height of the selfie stick with up/down, and camera tilting/(rolling ?) with left/right buttons
- It would use any standard Bluetooth controller with 2 analog sticks (while Micro$oft and Apple would create and sell dedicated controller :-( )

For Holywood productions, camboard movements could be performed in real time on a "flat" video shot by a drone above the scene, the camera being located by a moving blinking red spot on it, alongside with a VR stream of the camboard camera.

The question about this idea (remember, CC BY-SA) is not "Will it become a reality ?".
The question is : "When will it become a reality ?"
