Articulated Hand and Eye Tracking in Unity

HoloLens 2 has introduced some new and exciting capabilities, such as Articulated Hand and Eye Tracking.

The easiest way to leverage the new capability in Unity is through MRTK. There are also some example scenes to help you get started.

Building Blocks supporting Hands, eyes and others in MRTK

MRTK v2 provides a set of UI Controls and building blocks to help you accelerate your development.

Button Button Bounding Box Bounding Box Manipulation Handler Manipulation Handler
A button control, which supports various input methods including HoloLens2's articulated hand Standard UI for manipulating objects in 3D space Script for manipulating objects with one or two hands
Slate Slate System Keyboard System Keyboard Interactable Interactable
2D style plane, which supports scrolling with articulated hand input Example script of using the system keyboard in Unity A script for making objects interactable with visual states and theme support
Solver Solver Object Collection Object Collection Tooltip Tooltip
Various object positioning behaviors such as tag-along, body-lock, constant view size, and surface magnetism Script for lay out an array of objects in a three-dimensional shape Annotation UI with flexible anchor/pivot system, which can be used for labeling motion controllers and object.
