Question
Answer
SDK 1 How do identify whether Vive
Tracker or the controller is being
tracked?
You can use the class type of SteamVR SDK to
identify if Vive Tracker or the controller is currently
being tracked.
2 Does Vive Tracker have a different
coordination system compared to
the controllers?
Yes. Content developers need to apply different
coordination settings based on the position where the
Vive Tracker is mounted.
3 How can I replace the controller
with Vive Tracker if I already
created content meant for the
controller?
Content developers need to apply different
coordination settings based on whether Vive Tracker
is mounted on the same position as the controller.
If its position is different, content developers need to
recalibrate for Vive Tracker.
4 What's the equivalent of Vive
Tracker's hardware button to the
controller?
The hardware button of Vive Tracker maps to the
System button of the controller.
5 How can I simulate the button event
when I connect Vive Tracker to a
computer through USB?
Check the "Data format" section in the developer
guidelines, and follow the SetFeature 0xB4 format to
fill your simulated data in "Button byte" data.
6 How can I simulate the controller
trackpad when I connect Vive
Tracker to a computer through
USB?
Check the "Data format" section in the developer
guidelines, and follow the SetFeature 0xB4 format to
fill your simulated data in "Pad X" and "Pad Y" byte
data.
7 Why is tracking lost when I
connected Vive Tracker to a USB
cable?
When you connect Vive Tracker to your computer
using a USB cable, it enters data sending mode. To
resume tracking while connected to a USB port, follow
the developer guidelines to send the SetFeature 0xB3
command to fill Host type byte.
8 Can we implement our own data
into Vive Tracker's data stream?
Vive Tracker only supports data that's compatible with
the controllers.
