Introduction
Overview
Augmented reality bridges the gap between the real and digital worlds. The Wrap
920AR provides eyes through which to see those worlds.
The Wrap 920AR augmented reality eyewear from Vuzix Corporation are a wearable
display that provides a visionary portal into the worlds of virtual, mixed and
augmented reality from your true perspective. Its dual camera system capture real-
world images in stereoscopic 3D, its near-eye display system provides a combined
stereo image of the real-world video capture and computer generated content, stereo
earphones add audio into the mixture and a 6 degree of freedom head tracker locks
the were you look to what you see for a complete AR solution.
While developing the Wrap 920AR, Vuzix recognized that AR can and will be
applied in many different ways and not all AR applications will use a common set of
components. The versatility of the Wrap 920AR’s modular design works well in this
regard, allowing you to customize your unit based upon your needs.
Below is a brief description of the Wrap 920AR’s major components, many of which
are also available as separate products from Vuzix.

Wrap 920
The Wrap 920 video eyewear forms the base of the Wrap 920AR. It provides a 67-
inch virtual display, as seen from 10 feet. The Wrap 920AR can be worn like a pair
of sunglasses and used solely as a wearable 67-in display for viewing videos, or
computer content. It supports standard 2D video and a simple change of its
configuration, through an on-screen options menu, enables it to display any one of
multiple stereoscopic 3D video formats. Removable earphones round out this
product for the ultimate portable big-screen experience.
Wrap Stereo Camera Pair
The most visually apparent feature of the Wrap 920AR is its stereo camera pair
mounted into the face of the eyewear. With dual cameras spaced to approximate the
visual perspective of your eyes you can capture markers and similar objects or
complete scenes in stereoscopic 3D.
Image capture is a key component in augmented and mixed reality. The Wrap
cameras capture video 60 frames per second in 640 x 480 resolution and are
recognized by your computer as independent USB webcams. No special or
proprietary APIs are required to access and process what they capture.
Wrap VGA Adapter
A Wrap 920 is designed for flexible convenience. Out of the box it connects to
virtually any media devices that supports composite (RCA) video – which is pretty
much any non-computer media device. For computers, simply replace the eyewear’s
battery powered Control Box with a Wrap VGA Adapter. The VGA adapter can be
connected directly or through a standard gender-bender if you have a DVI or mini-
DVI video port and power is drawn through a USB connection. This connection
provides 2D and 3D stereoscopic video support when connected to virtually any
make or model of Windows compatible graphics card able to support dual monitors.
It works with desktop, notebook and laptop computers and comes complete with
Vuzix VR Manager providing stereoscopic video drivers and instant VR
compatibility with a wide assortment of games, simulators and other applications.

Wrap Tracker 6TC
Head tracking brings applications to life, placing you right in the middle of the
action. The Wrap Tracker 6TC is the newest and most advanced tracker system
available on the consumer market and it’s included with each Wrap 920AR. This
tiny 6 DoF (degrees of freedom) capable tracker, with compass, plugs into a small
port on the Wrap 920 and communicates head movement data through the Wrap
eyewear and it VGA Adapter’s USB connection.
Software developers can utilize tracking examples provided in the Vuzix SDK or they
can read raw tracker data.
Vuzix VR Manager™
VR Manager is a software application that provides tracker calibration, drivers for 3D
stereoscopic video, and VR support for a wide variety of games, simulators and other
applications.
maxReality™, Autodesk 3ds Max Plug-in (optional)
maxReality is a powerful plug-in for Autodesk 3ds Max. Together, 3ds Max and
maxReality allow users to create virtual and augmented reality worlds, saved as VWD
(Virtual World Descriptor) files. In addition to the 3ds Max capabilities maxReality
enables support for ambient and 3D audio, animation and other special effects such
as blue screening. The VWD files can be played back and viewed in 2D or 3D
stereoscopic video using a freely distributed maxReality Viewer application.
Tip: maxReality can be installed as a 15 day trial version – Autodesk 3ds Max required.
maxReality Viewer
The maxReality Viewer is a free viewer application for playing maxReality creations,
with or without Autodesk 3ds Max installed. The maxReality Viewer supports
playback of VDW files in 2D and 3D stereoscopic video, movement between scenes,
object interactivity, keyboard control and more.
Note: A Wrap 920AR is required to run the maxReality Viewer application and view VWD files.

Section 1
Wrap 920AR Setup & Install

Installation Overview
Though the Wrap 920AR is flexible and can be used in different configurations, its
setup is fast and easy.
The Wrap 920AR can be setup in either of two ways, for connection to a media
player or Windows based personal computer as your source device.
The first part of the instructions covers the installation of peripherals such as the
head-tracker and earphones. These items are unaffected by your choice of a source
device. Next, you choose your source device, a media player or a computer, and
follow the instructions specific to that source.
Each source device utilizes different components but you can quickly and easily
switch between sources at any time.
Peripheral Connections
Wrap Tracker 6TC
The Wrap Tracker is a 6 degree of freedom tracker with compass that plugs into the
Wrap 920AR in the video display unit near the right temple hinge.
!Plug your Wrap Tracker 6TC into the micro-port between the right
temple hinge and the right earphone port on the back of the display
module.

Note: Although the Tracker connector looks much like a UBS micro-B port, it is not. Do not attempt to
connect a USB micro-B connector into this port and do not attach the Wrap Tracker 6TC to a USB
micro-B cable or device.
See Section 4 “Wrap Tracker 6TC” for more information.
Wrap Noise Isolating Earphones
In addition to providing great sound quality, the earphones provided with your
Wrap AR eyewear are noise isolating and removable.
The earphones come with three pairs noise isolators to allow you to choose the set
that provides the best comfort and fit. The noise isolators simply slip on/off the
audio post.
!Plug an earphone into the audio ports on either side of the display module.
Your Wrap eyewear can be used with or without the earphones. To use the eyewear
without the earphones:
!Unplug the earphones from your Wrap AR eyewear and control volume using
the volume control provided by your media source.
See Section 2, “Wrap 920 Video Eyewear” for more information.
Media Player Connection
Note: If you are connecting your Wrap AR eyewear to a computer system, disregard this step and
proceed to “Windows Computer Connection”.

Wrap 920AR can be connected to virtually any media source with compatible
audio/video connects. Your eyewear includes a composite (RCA style) cable set as
well as a composite cable for Apple iPod, iPod touch, iPhone and iPad. Additional
cables and accessories are available from the Vuzix website (www.vuzix.com).
Note: Various AR functions are not currently compatible with media players. Vuzix is working to
address this within the current media player hardware limitations. Check the Vuzix website
periodically for new developments.
Your Wrap AR eyewear comes with two Control Boxes. The one used to connect to a
Windows based PC has a VGA and a USB cable. The one illustrated below, without
any attached cables, is used to connect to media players.
The media player Control Box serves two functions; it provides eyewear display and
audio controls as well as power for your video eyewear from two (2) AA batteries
(included).
To install the batteries:
!Open the back of the media player Control Box and insert the two AA batteries.
oPull the lid closure tab back and swing the door up to open the battery
compartment.
oInsert the batteries as indicated and then close the lid.

This Control Box provides two cable connectors. The rectangular port is for the cable
coming from the video eyewear and the round port is for the cable going to your
media player.
!Plug the eyewear’s Multi-connect Cable from your eyewear into the matching
connector on the Battery/Control Box.
The black side of the connector tip and the Vuzix imprint face up toward the buttons
on the Control Box.
!Connect a Vuzix compatible composite cable into the Control Box port labeled
“AV”.
Note: Be sure to insert the connector fully into the AV connector. Partial insertion is a common error.

You can use the RCA style composite cable or the custom Apple composite cable
provided. Additional cables are available from the Vuzix website (www.vuzix.com).
!Connect the composite cable to your media player.
Note: The eyewear will automatically turn off if no video signal is received for approximately 30
seconds. Turn on your media player before your eyewear to prevent this.
Windows Computer Connection
For full support of your Wrap AR peripherals, you’ll want to connect your Wrap AR
eyewear to a Windows based personal computer. Windows 7, Vista or XP (32-bit
and 64-bit) are supported. Virtually any hardware configuration (netbook, laptop or
desktop model) can be used as long as it support dual monitors.
Note: Though users have reported success connecting to other operating systems, some features and
components may not function as intended. Alternate operating systems are not supported at
this time and they are not eligible for technical support.
PC Hardware Connection
When connecting your Wrap AR eyewear to a Windows based personal computer,
the battery powered Control Box is not used and the Wrap VGA Adapter (the
Control Box with the VGA and USB cables) is used in its place.

The Wrap AR eyewear has two cables. The cable with the larger connector and the
chrome dot is the USB connector for the cameras. The smaller connector, with the
Vuzix imprint, is the eyewear Multi-connect cable.
!Connect the Wrap eyewear’s Multi-connect cable to rectangular port on the
Wrap VGA Adapter.
!Connect the VGA cable from the Wrap VGA Adapter to an available video port
on your computer.
If your computer has a DVI video port, you can use the provided DVI to VGA
Adapter. If your computer is equipped with another format of video connector, you
will need to acquire an appropriate VGA adapter.
!Connect the remaining two USB cables to USB 2.0 ports on your computer.
Note: If you are using a desktop computer you may find it convenient to add VGA and USB 2.0 cable
extensions.
The USB cable for the Wrap eyewear cameras provides data transfer and power for
the camera. The Wrap Multi-connect cable audio, video and tracker data transfer as
well as power for those components. If you are using a USB hub for connecting your
eyewear, it must be USB 2.0 compliant and have an external power supply.
Tip: Although many of you will be tempted to look in the Wrap eyewear display now, you’ll likely see
nothing other than a blue screen at this time. This is perfectly normal. The proper video image

cannot be displayed until the appropriate drivers have been installed and the video configured
correctly.
System Preparation
It is important that your system be properly prepared before you begin the software
installation.
Tip: Following these few simple precaution will minimize the risk of conflicts and the time and
frustration required to find a resolution.
!If you have any 3rd party stereoscopic display drivers installed, uninstall or
disable them before proceeding.
!If your system has any prior versions of VR Manager or Vuzix iWear VR920
support software installed on your computer, use the Windows Programs and
Features Control Panel to uninstall them before proceeding.
!If you have a Vuzix SDK installed, uninstall it before proceeding. You can
reinstall the latest version after this installation has been completed.
!You must have Autodesk 3ds Max (2010 or 2011) installed if you wish to use the
maxReality plugin.
Tip: If you wish to try maxReality but don’t have 3ds Max, you can download and use a trial version
from the Autodesk website.
!Your Wrap eyewear, VGA Adapter and Wrap Camera Pair must all be connected
to your computer before proceeding with the software installation. Some
drivers will not install if they are unable to find the appropriate hardware
connected.

additional information any updated information that may not be in this User Guide.
!Read the Readme.txt document now, if you have not already done so.
Wrap Master Installer
The Wrap software installer (setup.exe) combines several installation programs
combined into a single package. When run, it will call each of the individual
installation programs matching your system profile.
Vuzix VR Manager A Vuzix program that provides tracker calibration, virtual
reality 3D video and tracking support for a large number
of applications and 3D stereoscopic video drivers.
DirectX A linked DirectX installer required to ensure the
correct DirectX version is installed.
Vimicro Camera Driver Drivers for the Wrap camera pair and “AMcap”, a
Microsoft DirectShow video capture utility.

maxReality An Autodesk 3ds Max plug-in that enables the
creation of interactive VR and AR worlds. If Autodesk
3DS Max is not installed on your computer, this
portion of the software will not install.
maxReality Viewer An application for viewing maxReality creations
without the need for Autodesk 3ds Max. It will install,
even if 3ds Max is not detected.
!Open the decompressed software folder and run the “setup.exe” program.
During the installation process, the screens, options and buttons displayed will vary
from one version of the Windows to the next. We suggest choosing the default
options.
During the installation process you’ll be presented with a “Complete” and a
“Custom” install option. The “Custom” option enables you to choose which
components of some software are or are not installed. Unless you are familiar with
the components and the potential ramifications of not installing them, we suggest
choosing the “Complete” installation option.
The first installation will be for the Vuzix VR Manager software.
!Select the “Complete” option to install all the provided programs and drivers.
During the VR Manager installation the DirectX, XNA installer will launch.
!Allow the DirectX, XNA installation.
Next the Vimicro USB2.0 UVC PC Camera installer will launch followed by the
maxReality installer.
The maxReality installer will determine if Autodesk 3ds Max is installed on your
computer. If it is installed, both the maxReality plugin and maxReality Viewer
application will install. If neither 3ds Max program is found, only the maxReality
Viewer application will install.
