Introduction

This document describes the installation and use of the DynaVox EyeMax for eye tracking.

The EyeMax enables a user to make selections by fixing his or her gaze at specific objects on

the device screen. Once the EyeMax is properly connected and calibrated, conversation,

environmental control, and even email and the Internet are only a blink (or gaze) away.

Be sure to read through the step-by-step instructions in this document to learn the proper

installation methods and ways to customize the software to best suit the needs and

capabilities of the device user.

SYSTEM REQUIREMENTS

In order to use the EyeMax properly, you must have the following:

• DynaVox speech generating device. The EyeMax connects to two different models of

speech generating device:

• DynaVox Maestro

• DynaVox Vmax+ Dual Core

NOTE

See the picture on the previous page for reference.

• DynaVox Series 5 Software: No matter if you use a Maestro or a Vmax+, your speech

generating device must be running version 1.07.2 (or later) of the Series 5 Software.

• Mounting system. The EyeMax System (EyeMax + speech generating device) is not a

hand-held system. It must be securely mounted for proper positioning.

ABOUT THIS USER’S GUIDE

This document contains descriptions of and instructions for performing the basic operations of

your EyeMax. Throughout the text, you will find the following kinds of comments:

NOTE

This document offers notes on making the most of your communication system. These notes are

designed to highlight features that can be used to make the device a better fit for an individual

user, or point out other important considerations.

CAUTION

You should always be sure to read the notes beside the caution symbol. These notes contain very

important information to help you use your DynaVox hardware safely, and to prevent device

damage and loss of information.

REFERENCE

Many of the topics in this document are explained in more detail in the Series 5 Searchable Help

that can be launched on your Maestro/Vmax (or the CD and/or DVD that came with your Maestro/

Vmax). The reference notations include a key word or phrase that can be used to quickly find the

topic in the Searchable Help.

EyeMax User’s Guide 3

Part # 401216-C

Chapter 1: Introduction

EMERGENCY USE (INTENDED USE OF THIS PRODUCT)

The Maestro/Vmax and EyeMax are intended for everyday communication situations. They

should not be relied upon as a means of communicating emergency medical information. We

recommend having multiple ways to communicate information during a medical emergency.

CAUTION

The EyeMax emits infrared light, which may interfere with infrared-controlled devices. Do not use

the EyeMax in the same room with any infrared-controlled device if device failure could affect the

safety or health of the user.

PHYSICAL STRAINS

There are two types of strain that can occur from using any kind of eye tracking device: neck

strain and eye strain. This is true for using computer monitors as well. Recommendations for

alleviating such ‘monitor eye strain’ may be found by browsing to this Web site:

www.mayoclinic.com/health/eyestrain/WL00060.

If, at any time, you notice discomfort, pain, or fatigue in either your neck or your eyes, stop

using the EyeMax and rest until you feel well again.

The length of time that the EyeMax can be used before feeling strain or fatigue will vary from

person to person. You should listen to your body and rest when it tells you.

Trying out the EyeMax may initially be fatiguing to new users. This may be because they tend

to strain their eyes to reach and concentrate upon each target. A typical user will quickly grow

accustomed to the eye tracking process, and use of the system will soon become less

fatiguing.

Chapter 1: Introduction

LIGHT EXPOSURE

The EyeMax contains light-emitting diodes (LEDs) that emit light in the near-infrared spectra.

This type of infrared (IR) light occurs naturally in sunlight and also in light from incandescent

lamps.

Several national and international organizations provide guidelines for human exposure to

optical radiation, and recommend exposure limits for the eye and skin. The most prominent

are: the American Conference of Governmental Industrial Hygienists (ACGIH)1-2 in North

America, and the International Commission for Non-Ionizing Radiation Protection (ICNIRP,

1997). In the European Union, there is an Optical Radiation Directive that employs the ICNIRP

exposure limits in the workplace. Other organizations recommend product-safety emission

limits (ANSI, 2005, 2000, 2007; CIE, 2002; CENELEC, 2002; IEC, 2007; CDRH, 1995).

Currently, there are two sets of product safety standards that apply to the use of lamps—

including solid-state lamps (LEDs) worldwide. These are:

• The CIE Lamp Safety Standard: CIE Standard S009/E-2002, Photobiological Safety of

Lamps and Lamp Systems.

• The EN 60825-1 Laser Product Safety Standard

The maximum level possible with the EyeMax in any setting never gets close to the emission

limits set by these standards. A person using the EyeMax during regular operation is exposed

to less than 0.1% of the accepted long-time exposure according to EN 60825-1/A1-A2. This

exposure is also well within the safety guidelines given in the book, 1996 TLVs and BEIs, by

the American Conference of Governmental Industrial Hygienists.

PRODUCT CARE & HANDLING

To clean your Maestro/Vmax and EyeMax, first turn the Maestro/Vmax off and then wipe all

the hardware gently with a damp cloth or soft paper towel. You may dampen the towel with a

mild window cleaner to remove fingerprints, food particles, and dust.

Do not use tape or stickers on the Maestro/Vmax touch screen or on any of the plastic cases.

Additionally, do not cover the glass over the EyeMax camera or either of the infrared

transmitters. They are difficult to remove and may damage the device surfaces. Tape, stickers

and other sticky materials can damage the touch screen and interfere with the operation of the

devices.

Be sure to avoid getting any of your DynaVox devices wet. Never submerge them in water (for

example, in dishwater). If your devices accidentally get wet, shut them down immediately and

allow them to dry thoroughly. If after 24 hours you find that the devices seem to function

normally, there is probably no damage. If the devices fail to function or behave abnormally,

contact DynaVox Technical Support:

• US and Canada - Monday through Friday, 8:00 a.m. until 7:00 p.m. (Eastern Standard

Time): 1-800-344-1778.

• UK and Ireland - Monday through Friday, 8:30 a.m. until midnight: +44 (0) 1926 516250.

• Other European Countries, Asia Pacific, and the Middle East: please call the dealer from

whom you purchased your device.

You may need to ship the devices to DynaVox for repairs.

CAUTION

Never, under any circumstances, disassemble any of your DynaVox hardware - Maestro, Vmax, or

EyeMax. Doing so for any reason will void the warranty, and you will be responsible for the cost of

any required repairs.

Installation & Setup

This section describes how to properly attach and connect the EyeMax to your DynaVox

device (Maestro or Vmax).

NOTE

Since the device mount and mounting plate may be shipped separately, you may receive your

EyeMax kit from DynaVox before you receive the mount. If that is the case, the caregiver can still

connect the EyeMax to your Maestro/Vmax, charge the batteries, and begin to get familiar with

the Series 5 software. However, the entire system (EyeMax + Maestro/Vmax) must be properly

mounted before it can truly be put into use.

Installing/Replacing the Vmax Battery

When your Vmax is shipped, the battery is not installed. Before you can turn on your Vmax,

you must install and charge the battery.

NOTE

You may also follow the steps below if you need to replace the battery in your device with a new

battery from DynaVox Technologies. If the battery in your Vmax becomes unable to maintain

power after being charged, it could need to be replaced. You can order a replacement battery by

contacting DynaVox Customer Service/Sales Support.

To install (or replace) the battery in your Vmax:

1. If you are replacing a battery, turn the device off and, if necessary, disconnect the charger.

2. Lay your device face down on top of a soft cloth on a flat surface. You should be looking at

the support leg and the battery door on the back of the device.

3. Extend the support leg to uncover the battery door.

4. Using a flat-head screwdriver (or a coin), loosen the two screws that hold on the battery

door by turning them to the left (counter-clockwise). The screws cannot be removed

completely; when they are loose, they will spring up slightly from the battery door.

5. Lift the battery door away from the device’s case and put it in a safe place (you will need it

again if you ever disconnect the EyeMax from your Vmax).

NOTE

If you are replacing the current battery, lift it out of the battery well and set it aside.

6. Locate the connector slots on the bottom of the battery and the connector in the left side of

the battery well on the device case. Then, place the battery into the device case so that

the connectors fit together. The battery should lie flat in the battery well.

At this point, you must connect the battery door that is attached to the EyeMax, and make the

necessary cable connections between the two devices. Continue with Connecting EyeMax to

Vmax on page 14.

Connecting EyeMax to Vmax

The EyeMax is already attached to a replacement battery door for your Vmax. After you have

installed the battery, you should set aside the original battery door that came with the Vmax,

and attach the replacement battery door with the EyeMax.

After the battery door is in place, you can then make the necessary cable connections

between your EyeMax and your Vmax.

These instructions pick up where Installing/Replacing the Vmax Battery on page 13 left off.

To continue:

1. Place the EyeMax battery door on your Vmax and tighten the screws by turning them

clockwise (to the right). You should only have to turn them a quarter-turn or half-turn.

NOTE

After you replace the battery door, make a note of both your Vmax’s serial number, and the

EyeMax’s serial number. They are printed on the label on the battery door. Pull the Vmax+ Quick

Start guide out of the Vmax shipping box, and write the two serial numbers in the space provided

on the last page. This information will be handy if you ever need to contact DynaVox Technical

Support about your Vmax or your EyeMax. You will also need to write the Vmax serial number on

the registration card. Set the registration card aside. You can fill it out while the battery is charging.

2. If you plan to keep the EyeMax connected to your Vmax for an extended period, complete

this step. (If you plan to disconnect the EyeMax after a brief period, proceed to step 3.)

a. Use the supplied Allen wrench to loosen the black plastic “feet” that hold the support

leg in place on the back of the Vmax.

b. Remove the feet and set them aside.

c. Lift the support leg away from the Vmax and set it aside.

d. Place the supplied metal handle in the grooves that originally held the support leg.

e. Replace the black plastic “feet” to hold the handle in place.

f. Unclasp the nylon handle on the bottom of the Vmax, and remove both halves from

the strap attachment points (once the EyeMax is installed, this handle is not needed).

CHARGING THE BATTERIES

Each of the DynaVox devices (Maestro/Vmax and EyeMax) has an internal battery, and they

must all be charged. It can take up to 4 hours to completely charge the batteries. There are

three things to remember about these batteries:

• They will both charge at the same time.

• You cannot overcharge the batteries. You can leave the charger plugged in continuously,

and this will not harm the batteries in any way.

• You can still use the EyeMax system to communicate while the batteries are charging.

When your Maestro/Vmax battery begins to run out of power, the low battery icon will appear

on the right side of the title bar on the touchscreen (refer to the picture below). If you see this

icon, you should plug in your device to conserve the remaining power, and you should

recharge the batteries as soon as possible. The icon will remain visible until the batteries are

recharged.

LOW BATTERY ICON IN THE TITLE BAR

NOTE

If the EyeMax battery begins to run out of power, the charging indicator LED on the left side of the

EyeMax will blink (see Left Side on page 7). You should recharge the batteries as soon as

possible.

If the batteries completely run out of power, your DynaVox devices will automatically shut

down. Any unsaved programming will be automatically saved before the devices shut down.

You will need to either charge the batteries or plug in the charger before you can turn the

devices on again.

NOTE

It is important to make sure that you use the EyeMax power supply/charger that shipped in the

EyeMax box. The Maestro/Vmax charger will not work with the EyeMax.

To charge the device’s battery:
