2 The Screen
Please prevent any mechanical damages and soiling to the screen!
Do not bring chemicals and sharp objects in touch with the screen! This can damage the screen.
If the screen is soiled be very careful while cleaning it. Do not use any chemicals! Please use only a
wet cleaning cloth! In doubt please contact a specialist!
3 The Projectors and the Cabling
While the projectors are switched on and immediately aer switching offthe projectors an
uninterrupted power supply has to be available. Otherwise the projector’s lamps can be damaged.
Somemes dust can be amassed on the projector’s light outlet. Do not use any chemicals to clean
this outlet. This outlet can only be cleaned by using cleaning equipment for opcs. A dry and so
cleaning cloth can also be used if the cleaning is done very carefully.
Only specialists are allowed to carry out repairs on the projectors.
Cleaning of filters inside the projectors has to be done by specialists.
Repairs of the cabling can only be done by specialists. Do not alter the cabling inside the short throw
projecon system and between the short throw projecon system and the pixel processor! Use high-
end DVI cables to connect your equipment to the short throw projecon system’s pixel processor!
4 The Housing
The housing is covered with a resistant paint.
Do not touch the housing with sharp objects! This can damage the paint and the appearance of the
short throw projecon system.
5 The Pixel Processor
To control the short throw projecon system use the “3DInsight Projecon System Manager”
installed on the control tablet. For further informaon see the “3DInsight Projecon System
Manager” manual.
If the system works and there is no input signal on the DVI connectors of the pixel processor it shows
a checkerboard paern.
Do not change the system setup of the pixel processor! If you change the sengs malfuncons of the
pixel processor can occur.

6Key Mapping of the Pixel Processor
By pressing keys on the keyboard of the pixel processor it can be switched to several working and
tesng modes. If the pixel processor does not react on keyboard inputs do a leclick with the pixel
processor’s mouse.
6.1 Calibrated Output
This is the mode the short throw projecon system uses normally aer startup. If you want to return
to this output mode press the key ‘c’.
6.2 Uncalibrated Output
If you want to show the output of the minVR Wall in uncalibrated mode press the key ‘u’.
6.3 Zooming out One of the Four Segments of the short throw projection
system
By pressing ‘1’ to ‘4’ the corresponding segment is zoomed out. Pressing ‘0’ shows the whole image
consisng of all four segments.
6.4 Flipping the Order of the Eyes for Stereoscopic Output
By pressing ‘x’ le and right eye for stereoscopic output are changed.
6.5 Switching to Several Test Modes
By pressing ‘t’ the first me the pixel processor shows a blue image with the text LEFT on one eye
and a red image with the text RIGHT on the other eye. This can be used to check if le and right eye
for stereoscopic output are interchanged (see the previous paragraph).
By pressing the key ‘t’ the second me the pixel processor shows a stereoscopic photo for tesng
purposes.
By pressing the key ‘t’ in conjuncon with ‘Shi’ these test images are displayed on each segment.
Pressing the key ‘c’ lets you return to the calibrated output mode.
6.6 Close the pixel processor’s software manually
If you want to close the pixel processor’s soware manually you have to press the key ‘Shi+q’. The
soware can be restart by double-clicking the Icon ‘VRWall’ on the pixel processor’s desktop.
6.7 Keys to affect the synchronization of the short throw projection
system’s segments
For a pleasant stereoscopic output it is necessary that all four segments show the outputs
synchronized. Therefore a synchronizaon mechanism is integrated in the short throw projecon
system. There exist keys to influence this mechanism. A user should not affect these parameters. If
you think the synchronizaon was influenced by you restart the pixel processor.

6.8 Keys for Automatic calibration
If you connect your calibraon camera directly to the pixel processor you are able to do a nearly
automac recalibraon. This automac recalibraon can be iniated by pressing a buon of the
control tablet (Chapter 6.2.3 of Tablet Soware Descripon). Another way to do an automac
recalibraon is to iniate it by pressing the key ‘Enter’ once on the pixel processor’s keyboard. This
acvates the start screen of the calibraon mode.
6.8.1 Adjusting the offset parameters of each segment
Pressing the key ‘s’ in the calibraon start screen makes it possible to adjust the offset parameters of
each segment.
The keys ‘Picture Up’ and ‘Picture Down’ let you choose the segment. The keys ‘arrowle’ and
‘arrowright’ let you choose the border part (le, right, top, boom)of a segment. The keys ‘arrow
up’ and ‘arrowdown’ let you increment and decrement the offset value of the chosen border part of
a segment. You should see a green border around each segment.
Pressing the key ‘enter’ saves your adapted values and lets you return to the start screen of the
calibraon mode. Pressing the key ‘Esc’ discards all your changes and returns to the start screen of
the calibraon mode.
6.8.2 Adjusting the camera’s position in front of the screen
If you are in start screen of calibraon mode (you pressed ‘Enter’ once on the pixel processor’s
keyboard while you were in calibrated output mode.) you can also check if the camera sees the
whole screen.Therefore press the key ‘s’ to get into setup mode.
If you use an usb camera press the key ‘c’ to get the connuous image stream from the camera. Use
this view to posion your camera properly.
If you use an SLR camera press the key ‘p’ to take a snapshot. Repeat the posion adjustment and
taking snapshots unl the camera sees the whole screen.
Pressing the key ‘ESC’ lets you return to the start screen of the calibraon mode.
6.8.3 Starting the automatic calibration
Pressing the key ‘Enter’ in the calibraon start screen starts the calibraon.
Several precondions have to be fulfilled to do a successful recalibraon. Look into the descripon of
the control tablet soware for a detailed descripon of these pre-condions (Chapter 6.2.3). Aer
starng the calibraon the camera setup is done. Aerwards the calibraon paerns are recorded.
Then these images are used to extract calibraon parameters. If this process was successful the
message “Calibraon successful“ is displayed. Otherwise the message “Calibraon failed“ is
displayed. Successful calibraons are applied immediately. Failed calibraons are discarded and do
not change the system’s state.
By pressing the key ‘Enter’ the final system message is confirmed and you leave the calibraon mode
and return to normal calibrated viewing mode.

7 The Control Tablet
The mini VR Wall is controlled by the control tablet. It communicates with the components of the
short throw projecon system via wireless LAN.
The control tablet is switched on by pressing its power buon. Aer boong the “3DInsight
Projecon System Manager” is started automacally. See the “3DInsight Projecon System Manager”
user’s manual for further instrucon.
The control tablet can be used in conjuncon with the docking staon or via its touch display.
Do not change the system sengs of the control tablet! This can lead to malfuncons of the
“3DInsight Projecon System Manager”.
Handle the control tablet’s touch display with care! Do not touch it with sharp objects!
8 The Calibration Camera and its Accessories
The short throw projecon system is calibrated using a photographic method. Therefore a Nikon
DSLR camera with a high-end Nikon fish eye lens is used. During the calibraon the camera is placed
in front of the wall on a tripod. It is connected to the control tablet via an USB cable. For further
informaon regarding the treatment and usage of the camera, the lens and the tripod read the user
manuals.
Handle the camera and the lens with care! Do not drop the camera or the lens! This can destroy
them.
Camera and lens can only be cleaned by using special cleaning equipment for opcal equipment. In
doubt contact a specialist!
Use only the cables delivered with the camera to connect it to the control tablet during the
calibraon!
9 The Wireless LAN
The control tablet communicates with the pixel processor via wireless LAN. Therefore a WLAN-Access
Point is installed in the short throw projecon system.
The IP of this AP is 192.168.100.1.
The configuraon interface can be reached by typing hp://192.168.100.1 into your browser. The
user name for administraon purposes is admin. The password is minivrwall. The SSID is InsightAir.
It is WPA2 protected. The passphrase is minivrwall.
Do not alter any configuraon of the AP! This can lead to malfuncon of the short throw projecon
system.
