## Overview
|
|
This extension provides an XrPath for getting device input from a VIVE wrist tracker to enable its interactions. VIVE wrist tracker is a tracked device mainly worn on user¡¦s wrist for pose tracking. Besides this use case, user also can tie it to a physical object to track its object pose, e.g. tie on a gun.

### Interaction profile path:

|
|
|
|
### Valid for user paths:
|
|
- /user/wrist_htc/left
|
