Right out the box, the HTC Vive comes with two controllers and two base stations. This is sufficient for the majority of VR experiences, however we’ve been tinkering with the hardware and software to see what can be accomplished outside of the standard setup. In these experiments we observed the capacity of Vive’s tracking power.
How Many Controllers Can You Run in SteamVR?
Prior to the release of the Vive trackers we wanted to explore the viability of implementing foot controllers to the Vive for added experiences such as kicking or juggling a soccer ball. In order to prove the concept, we synced another pair of controllers to SteamVR and strapped them onto sandals.
We were able to enable successfully foot interactions in our freestyle sports demo, which allowed a user to control both their feet as well as their hands simultaneously (video below).
