Introduction Your iWear VR920 video

eyewear incorporates the latest in virtual reality technology.

Two high resolution LCD displays that appear as a 62 in. screen as viewed from a distance of 9 ft.

5

Introduction Standard 2D monoscopic video is displayed by default

and 3D stereoscopic video when used in conjunction with supporting software and graphics card.

Pitch, roll and yaw head tracking is also available when used in conjunction with supporting software.

An integrated audio system with detachable headphones and a microphone provide an all-in-one solution for in-game chat and VOIP communications.

Calibration 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

13

Calibration 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.

14

Calibration 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.

15

Calibration 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.

Connect vuzix VR920 to unity with TrackIR

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.

Microsoft Kinect 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.

Implementation

1. Downloading and Installing the SDK2. Bringing the Kinect SDK in to Unity

Install the Unity Package

24

Scripts in kinect unity package

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.

25

Scripts in kinect unity package

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.

26

Scripts in kinect unity package

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.

27

Scripts in kinect unity package

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.
