This document describes the Vuzix iWear VR920 virtual reality headset. It includes descriptions of the headset components and specifications, calibration process using included software, and usage with the Unity game engine and Microsoft Kinect for motion tracking integration. The headset features dual LCD screens providing stereoscopic 3D imagery, integrated audio, and head tracking via onboard sensors. Calibration ensures accurate head tracking over time. Unity and Kinect SDKs allow development of VR applications with support for head tracking and motion controls.

12.  The last step is calibrating the
head tracker.
 The iWear VR920 video eyewear
computes head tracking data
through a series of 3 magnetic
sensors and 3 accelerometers
mounted inside the display
enclosure.
› Yaw
› Pitch
› Roll
12

13.  As the magnetic fields around us change constantly and your
eyewear must be periodically calibrated to adjust for these
fluctuations and their effect on the magnetic sensors.
 If you change the location of your eyewear, even from one side of
room to another or if you reposition items that emit an
electromagnetic field in its proximity, it should be recalibrated.
 Magnetic fluctuations caused the rotation of the earth, will affect its
magnetic sensors slowly over a period of time. If you find its
accuracy has changed – recalibrate.
13

14.  Open the iWear VR920 Calibrator
application.
 Press the “Begin Calibration”
button.
 Hold the eyewear facing your
monitor, with the temples fully
open.
 Rotate the eyewear fully through
each axis; pitch, roll and yaw.
14

15.  When you have completed rotating
the eyewear fully through all 3
axes, and then press the “Lock
Calibration” button.
 Place the eyewear on your face as
you would normally wear it.
 Face your desktop monitor and
press the “Set Zero” button.

17.  a fully integrated
development engine that
provides rich out-of-the-box functionality to
create games and other interactive 3D content.
 used to assemble our art and assets into scenes.
 Unity support deployment to multiple platforms
Such as Windowos,Mac,Linux,Android,ios,xbox360and Wii
.

18. SDKs & packages :-
 Oculus Rift (Unity pro required)
Unity 4 : SDK
Unity 3.5.7 : Package
 Razer Hydra (Unity pro required)
Sixense Unity plugin
Easy start-up package & Basic demo (don't forget to credit Alex)

TrackIR
Package (thanks to Tobbe)


19. Video TrackIR with unity
Steps:-
1. there are plugin to connect vuzix with unity project
2. there are TrackIRCamera code that assign it to Main camera.
› this code take vuzix X,Y,Z position through plugin and vuzix
Yaw,Pitch,Roll Rotation through plugin ,then assign vuzix position and
rotation to Main camera in project.
 Note: we can assign vuzix position and rotation to object that
we want to take head tracking not main camera only.

21.  Kinect is a line of motion
sensing input devices by
Microsoft for Xbox 360 and
Abox One video game
consoles and Windows PCs.
 Based around a webcam-
style add-on peripheral, it
enables users to control and
interact with their console /
computer without the need
for a game controller,
through a natural user
interface using gestures and
spoken commands.

23. 1. Downloading and Installing the SDK
2. Bringing the Kinect SDK in to Unity
 Install the Unity Package
23

24.  KinectModelControllerV2 : This is the script that you will attach to
your model that you want to manipulate - you will drag each of the
bones to be controlled into the appropriate slot, and determine
which player controls which model.
 KinectPointController : This script will place GameObjects that
you define onto points that are tracked by the Kinect, generating a
skeleton. The starting scene comes with an example of how this
looks / should be done.
24

25.  DisplayDepth : This script will get the depth image. Attach it to a
game object with renderer. NOTE: In unity, you need to restart unity
everytime after running your world, otherwise this script will not
work (because of SDK issue).
 DisplayColor : This script will get the RGB image. Attach it to a
game object with renderer. NOTE: In unity, you need to restart unity
everytime after running your world, otherwise this script will not
work (because of SDK issue).
 KinectRecorder : This script will record your movement and output
playback files for the emulator.
25

26.  KinectEmulator : This script will act as a virtual Kinect. It works
with playback files. For now it only simulate the skeleton data.
 KinectSensor : This script gets data from the physic Kinect.
 DeviceOrEmulator : This script sets whether to use physic Kinect
or the emulator.
 SkeletonWrapper : This script grabs skeleton data.
26

27.  DepthWrapper : This script grabs depth image data.
 KinectInterop : This script grabs data from Microsoft Kinect SDK.
 Recordings/playbackDefault : This is the default playback file for
emulator. Do NOT remove this file.
