Hardware Description
The HeadMouse Nano is an infrared optical sensor that tracks
side-to-side and up-and-down head movements. It then filters and
transforms these movements to control the mouse pointer position
on a computer, tablet or communication device screen.
HeadMouse Nano is a modest power device and is usually
supplied directly from the device USB port. HeadMouse Nano
uses infrared light to track a tiny reflective dot that is placed on the
user's forehead or glasses.
When used with mouse utility software, such as Origin
Instruments' Dragger, mouse clicks are performed by positioning
the mouse pointer and dwelling for a selectable period of time.
Alternately, mouse clicks can be performed with an adaptive
switch, such as the Origin Instruments Sip/Puff Switch or Orby
switches. One or two industry standard adaptive switches can be
connected directly to HeadMouse Nano through a 3.5 mm stereo
jack located next to the USB connector.
The HeadMouse Nano also contains an integrated infrared
receiver for use with wireless switches. The optional Beam™
wireless switch transmitter supports wireless connections for up to
three adaptive switches.
HeadMouse Nano is connected to the computer, tablet or
augmentative communication device with a standard A, to micro-B
USB cable.

The aluminum body of the HeadMouse Nano measures 2.1- by
1.5- by 0.35-inches, the optical transceiver extends another 0.15-
inches.For best results and reliable long-term operation, do not
touch the dark window. It is not necessary to clean the window as
part of a regular maintenance program.
A red and green LED is located on one side of the optical
transceiver. These LEDs indicate tracking status. The red LED
indicates that search is in progress. The green LED indicates the
HeadMouse has found and is tracking a target.
An infrared receiver for wireless switches is located on the other
side of the optical transceiver. Direct the optional Beam wireless
switch transmitter toward this receiver to communicate with the
HeadMouse Nano.

Located on the top edge of the HeadMouse Nano are a Micro-B
USB connector and a 3.5mm (1/8-inch) stereo microphone
connector. Connect a mono adaptive switch into the microphone
connector to provide a LEFT mouse button click. A dual-mono-to-
stereo adapter is available if you need to directly connect mono
adaptive switches for both LEFT and RIGHT mouse button clicks.
The HeadMouse Nano draws its operating power directly from the
computer, tablet or AAC device through the USB connector.

On the rear of the HeadMouse is an informational label and the
sensor serial number. This information is needed for
troubleshooting, repairs or warranty service.
A small piece of Dual Lock fastener is centrally located on the rear
panel of the HeadMouse Nano for use in mounting. The high-
density Dual Lock fastener is designed to mate with low-density
Dual Lock fasteners on mounts or directly on the bezel of your
computer's display. A kit of Dual Lock fasteners is included with
your HeadMouse Nano.
Four small DIP switches are accessible through an opening on the
rear panel of the HeadMouse Nano. These switches are factory
set and only rarely need to be changed by the user.
The default switch settings are all in the ON position.

Setup and Installation
The HeadMouse Nano is a “plug-and-play” USB device and does
not require any special software. Your device will recognize
HeadMouse as a standard desktop mouse.
Mounting
Think of the HeadMouse as a camera that should be positioned
and pointed so that you and your HeadMouse dot are nominally
centered in its field-of-view.
Optimal HeadMouse placement would generally be at the top and
center of the display bezel. Place the HeadMouse so that it does
not obscure the screen. A good rule of thumb is to position the
HeadMouse so that it is near eye level and pointing directly at the
target dot on your forehead. This will provide the user with
maximum range of motion.
The HeadMouse Nano is shipped with a Dual Lock mounting kit
and one or more universal brackets. There are other brackets
available from Origin Instruments, please visit http://www.orin.com
or call for more information.
The Dual Lock kit, can be used for mounting to a variety of
devices. Dual Lock has a strong adhesive backing on one side
and plastic, snap-locks on the other. It can be thought of as a
more secure and stable version of Velcro. Peel the backing off the
adhesive, afix a piece of low-density Dual Lock on the bezel of
your device and snap it to the piece on your HeadMouse. Be
aware, the pressure sensitive adhesive is very strong and not
easily removed, especially if pressed firmly in place and
allowed to set for several days.
The best way to locate the mating piece of Dual lock on your
device display is to mate it to your HeadMouse and with the
release paper in place experiment with different HeadMouse
positions. When you determine the optimum placement remove
the release paper and use the HeadMouse case to press the Dual

HeadMouse Nano User Guide
Origin Instruments Corporation Page 11
Lock adhesive in place. Be careful not to damage your device
display by pressing too hard. Do not press on the HeadMouse
window.
The pressure sensitive adhesive used on Dual Lock is powerful
and not easily removed.To remove, gently peel Dual Lock away
from your monitor. Excess adhesive can then be removed with an
appropriate adhesive removing solvent.
Universal Mounting Bracket
The universal bracket is designed to attach the HeadMouse Nano
securely to a variety of device displays −desktop, laptop, tablet
and communication devices. The adjustable bracket can
accommodate various thicknesses, and uses Dual Lock to secure
HeadMouse to the bracket.
Longer legs are included for use with thicker desktop displays.
Figure 4: For thicker desktop displays use the longer
bracket legs.

HeadMouse Nano User Guide
Origin Instruments Corporation Page 12
The bracket is held to the display using two adjustable rubber
tipped legs that clamp to the display. The bracket is held securely
in place by tightening individual thumbscrews on each mounting
leg.
After attaching the mounting bracket to your device, simply snap
the HeadMouse in place.

Connection
After the HeadMouse Nano is mounted, use the appropriate cable
and connect HeadMouse to the USB port on your computer, tablet
or communication device. If an adaptive switch is being used to
perform mouse clicks, connect it to the switch input jack on the
HeadMouse Nano. (Dual switch users please refer to Dual and
Multiple Switch section)
Turn on the computer or communication device. The status LED
on the HeadMouse Nano will light and turn red to indicate that it is
receiving power.
Once the HeadMouse begins tracking the status LED will turn
green.
NOTES:
1. Some computers can take more than 60 seconds to
recognize HeadMouse Nano when it is first plugged-in to a
USB port.
2. You may need to click in a dialog box to indicate that no
special device driver is provided or needed.
3. When connecting through a USB hub, a powered hub is
recommended. With some computers, a non-powered hub
may be acceptable but connection through a non-powered
hub can impact the operation and/or performance of the
HeadMouse.
4. For best results use the USB cables that were delivered
with your HeadMouse Nano and do not use USB extender
cables.
Using HeadMouse Nano
Tracking Status
The red and green status LED on the front panel of the
HeadMouse Nano indicates tracking status. When the red LED is

HeadMouse Nano User Guide
Origin Instruments Corporation Page 15
on, it indicates that the HeadMouse is searching for a target dot. If
a bright object or a reflective object moves into its field of view, the
green LED may come on momentarily but HeadMouse will resume
its search if the object is not a target dot. When the HeadMouse
has located a target dot, the green LED comes on. After the
HeadMouse has located a target dot it will lock on to the dot and
will not be affected by another dot until something obstructs its
view and breaks tracking lock.
NOTE: If both LEDs are off, the HeadMouse is not receiving
power or USB enumeration has not occurred.
General Use
Place a target dot on the user’s forehead or glasses. The
HeadMouse Nano will immediately locate the dot and the pointer
will move with the user’s head movements. The HeadMouse Nano
offers very precise pointer placement. Optimally the user should
be 18- to 24-inches (45- to 60-centimeters) from the HeadMouse
Nano, but can be as far as 5-feet (1.5-meters). The greater the
distance from the HeadMouse, the more head movement is
required to move the pointer from one edge of the screen to the
other. Clicking functions can be made by using an adaptive
switch, or dwell software. Please see Dual and Multiple Switch
section for details regarding using multiple switches.
Origin Instruments offers a variety of adaptive switches, on-screen
keyboards with built-in dwell, and dwell selection software for both
Windows and Mac OS X.
Pointer Position
It is best to take a few minutes to practice pointing. Just like the
desktop mouse will at times need to be repositioned to maintain
comfort, the pointer on the screen will also need to be
repositioned periodically when using the HeadMouse Nano. This
is often referred to as centering the pointer, or re-calibrating.
When the pointer is in the center of the user’s work area, the user
is most comfortable. The pointer will need to be re-centered as the
location of the work area changes. Keep in mind that you are not

HeadMouse Nano User Guide
Origin Instruments Corporation Page 16
necessarily centering the pointer in the center of the computer
screen but in the center of your work area. This is done by
“pushing” the pointer against the screen edge opposite the side of
your desired work area. It is best understood by walking through
an example.
Exercise Example: Sit in a comfortable position and take note of
where the pointer is on the screen. As an example, say the pointer
is at the bottom of the screen. To move the pointer to the top of
the screen attempt to move it past the bottom edge of the screen,
or “push” it against the bottom edge. Then move your head back
to the original comfortable position. The pointer will have moved
closer to the top of the screen. This same technique can be used
to reposition the pointer in the horizontal axis as well. This
centering technique becomes second nature within a few minutes.
Pointer Control
The mouse speed in the Control Panel/Preferences of the
computer, tablet or communication device determines the amount
of sensitivity the pointer has to movement. If the mouse speed is
set too fast or high, the pointer will move a greater distance with
less physical movement from the user. When the mouse speed is
set to slow or low, the pointer will move a smaller distance
requiring more physical movement from the user. Each user is the
best judge of what is most comfortable for his/her particular
abilities. Begin with the mouse speed settings at about ¾ of the
way to fast. Adjust from that point in small increments until the
user is comfortable with the settings. If the mouse speed is still too
slow for the user, additional adjustment can be made via the Mode
Switch settings on the HeadMouse Nano.
NOTE FOR MAC USERS: For those using the HeadMouse Nano
to access a Macintosh, it is best to begin with the mouse speed in
the fast setting as the mouse drivers in the Macintosh operate at a
slower speed than standard Windows drivers so increased speed
is often required.

Dual and Multiple Switches
The switch input jack can accept a stereo plug for emulation of
both left and right mouse buttons. The primary switch (or “left”
mouse button) should be connected to the “tip” of the plug. The
secondary switch (or “right” mouse button) should be connected to
the “ring” of the plug. For example, the Origin Instruments' Sip/Puff
Switch can be connected to the HeadMouse Nano through a
single stereo cable such that a “sip” produces a left click and a
“puff” produces a right click.
A dual-mono-to-stereo adapter is available to connect two mono
switches directly to the HeadMouse Nano. When using two such
directly connected switches, activate the primary switch (left
mouse button) at least one time before activating the secondary
switch (right mouse button).
It is generally best to connect switches before connecting the USB
cable. If you change from a stereo switch to a mono switch after
the HeadMouse Nano is connected and operating, please allow
30 seconds for the HeadMouse Nano to adapt to the new switch
connection.
Up to three switches can be connected to Beam Wireless Switch
Transmitter, to emulate a 3-button mouse.
