Should I be surprised that this doesn't work with Google's own Daydream? I would have assumed support for that before Vive and Rift. I'm assuming there are technical limitations to doing this on Daydream but is it just not doable at all on it? Is the control not precise enough or do you need two?

Edit: Okay thanks for the clarification! I guess I wouldn't be surprised if Google has it working internally on their own standalone Daydream hardware.

When Google releases a 6DOF standalone or mobile Daydream they will port all of their desktop PC VR apps to mobile. We're close to this, as the standalone Daydream hardware (mobile Vive) has 6DOF inside out headtracking, even though it lacks a 6DOF controller required for all VR content creation apps. For now, mobile devices don't have the input and tracking capabilities to provide a good modeling experience.

Performance aside, Daydream does not have 6DOF.

There's a bunch of hacks you can do around 3DOF, but the experience would be severely crippled without 3D tracked controllers.

once 6DOF technology gets more advanced and more distribution, is there any use case or niche for 3DOF where it is actually the better solution?

As far as UI goes I can see it being a keyboard to your mouse. Some UIs like menus are actually easier to design and interact with in a 3DOF plane.

But as far as hardware goes 3DOF is just a stepping stone; we only use it because it's easier to make. Once good, efficient 6DOF is available we can pull 3DOF out of it whenever we need to.

Other than cost to produce, not really and you can always ignore position or rotational tracking to drop down from six to three which will likely be the default when losing tracking from an inside out system.

Assuming rough parity in terms of simplicity and cost, no. Unlike, the limited range of B&W photography vs. color, there is no intrinsic value in having a compromised sense of space and severely limited range of motion when using immersive media.

Not if you understand the difference between a system that only tracks three degrees of freedom (i.e., rotational motion only / e.g., Daydream and GearVR), and one that tracks all six (i.e., rotational + translational / e.g., Vive and Rift).

Since 3 DoF systems are widely-viewed within the industry as being time-limited, most designers with long-range plans for their work will build for 6 DoF first and foremost, and maybe develop a 3 DoF version if the basic concept and funding stream allows.

Being a general authoring tool rather than a specific title, Google's VR Blocks fit squarely (sorry) in the Do 6 DoF First category.

vive and rift are accurately positioned in space while daydream has just an approximation from the gyro and a lot less inputs. So yeah, basically just not doable on this platform and similar ones like samsung's
