Are there any updates on google cardboard support?

DISCLAIMER: I have no idea if this is going to help you along, but here’s what I know from experience so far.

I know there are some bluetooth clickers on the market. They simulate a tap on the screen/Using the Magnet Clicker. VR interaction on a controller free platform has 2 main interactions right now. Using a click of some kind (like the clicker or cardboard magnet) in combination with a reticle, or a lookAt interaction of sorts, either time based or rollOver based, depending on the kind of interaction you’re looking to have happen. Hope that shoots you into the right direction, or helps a bit. WAA! and Vanguard V are great examples of the clicker-less interaction.
