Read the following before using this product:
The RED-m Eye Tracking Device is a sophisticated measurement
device. Please handle it with care in order not to damage any of its
internal components.
When not in use, the RED-m Eye Tracking Device should be unplugged
from the USB port and safely stored in the case.
When in use, do not unplug the device from the USB port.
Do not scratch the shield (the front face) of the RED-m Eye Tracking
Device.
No part of the product maybe modified or rebuilt.
Any usage other than described in this manual is not permitted.
Note: Read the section Optimal User Conditions before you permit a

1.4 Safety Information Regarding Magnets
The RED-m Eye Tracking Device contains Neodymium magnets (Rare
Earth magnets) to conveniently connect the RED-m Eye Tracking Device to

a mounting bracket attached to the PC monitor. However, this type of
magnet is extremelystrong and must, therefore, be handled with extreme
care.
Handling Warning
Finger Pinch
Warning
Do not confuse Neodymium magnets with standard "fridge magnets'.
This type of magnet can cause injury if not used properly.
Do not place your fingers between the two magnets while connecting the
RED-m Eye Tracking Device to the mounting bracket. The two attracting
magnets have enormous strength and can severely pinch your fingers if
they come between the magnets when theyare connecting together.
Do not let the RED-m Eye Tracking Device freely connect to the mounting
bracket. Although the Neodymium Magnets have high strength, theyare
also very brittle and prone to cracking and chipping. If connected too
quickly, or if the RED-m Eye Tracking Device is dropped, the magnets
may shatter and scatter shards of the magnet, possiblyeven towards the
user's eyes.
Neodymium magnets have strong magnetic fields and likely to cause
damage to magnetic media devices. Therefore, keep the RED-m Eye
Tracking Device away from magnetic media such as hard drives,
memorysticks, credit cards, magnetic I.D. cards, or other magnetic
media. KEEP THE DEVICE IN THE STORAGE CASE WHEN NOT IN USE.
Do not place metal items near the magnets on the RED-m Eye Tracking
Device. The metal items, such a keys, knives, or tools maycause the

magnet to shatter.
Do not leave the RED-m Eye Tracking Device near an open flame or a
heat source. Aside from destroying the device, the neodymium magnets
will ignite, burn and create toxic fumes.
HEALTH WARNING
Pacemaker
Warning
Neodymium magnets should NEVER be used near a person who uses
medical aids such as a pacemaker. The magnet can cause the medical
aid to malfunction. Individuals with pacemakers or internal medical
devices should use caution when handling the RED-m Eye Tracking
Device and the mounting bracket. Magnetic fields mayaffect the
operation of these devices. Consult your physician and the manufacturer
of your medical device to determine its susceptibility to static magnetic
fields prior to handling the RED-m Eye Tracking Device and the mounting
bracket. All of our magnetic products should be kept at a safe distance
from individuals with these devices.
Do not handle the RED-m Eye Tracking Device when eating. The metal
compounds in the magnets maybe toxic when ingested after handling
food.
WARNINGFOR CHILDREN
NEODYMIUM MAGNETS (RARE-EARTH) MAGNETS SHOULD BEKEPT OUT
OFREACH OFCHILDREN. RARE-EARTH MAGNETS ARENOT TOYS.
Children should not be allowed to handle or play with rare-earth magnets.
Small magnets pose a choking hazard. Children and adults should not

ingest magnets or place magnets in any bodyorifice such the ear, nose or
mouth. Ingestion of magnets is very hazardous. If magnets are ingested or
aspirated to the lungs, immediate medical attention is required. Swallowed
magnets can stick together across intestines causing serious infections
and death. Seek immediate medical attention if magnets are swallowed or
inhaled. Children under 3 should not handle magnets, in anycase.
Transportation
The International Air Transport Association (IATA) Dangerous Goods
Regulations provide guidelines for the identification, classification, and
testing of potentiallyhazardous materials offered for transports by air. IATA
Packing Instruction 902 defines the acceptance criteria and provides
packaging guidelines for magnetized material. These instructions should
be consulted prior to transporting magnetic material by air. These
regulations also apply to magnets built in to products such as the RED-m
Eye Tracking Device and mounting bracket.

2.3 Quick Start
The following is a summaryof the steps required to set up the RED-m Eye
Tracking System.
Preparation:
1. Run the Installation Package. See Running the Installation Package.
2. If you are using a Desktop PC, attach the RED-m Eye Tracking Device to
the mounting bracket which you attach to the bottom edge of the
monitor. See Attaching the Mounting Bracket to a PC Monitor.
3. If you are using a Laptop, place the device in the hinge area. See
Placing the Eye Tracking Device on a Laptop.
Setup:
4. Start the iViewRED-m application, which will also start the iView Eye
Tracking Server. See Running iViewRED
5. Select or create a user profile. See Creating a User Profile.
6. Ensure the user is sitting in a comfortable position of approximately65
cm (approx. 26 inches) from the screen. See Optimal User Conditions.
7. Orient/tilt the RED-m Eye Tracking Device towards the eyes of the user.
8. Set the measurement values in the Geometry Settings area of the
iViewRED-m application. These values are critical for accurately
tracking the user’s eyes. The iViewRED-m application needs to know
precisely where the RED-m Eye Tracking Device is located relative to
the screen. This is done by:
Measuring the height and distance of the RED-m Eye Tracking
Device to the PC Desktop monitor or Laptop screen.
Measuring the width and height of the PC Desktop Monitor screen

(not including the frame), or if using a Laptop, the Laptop screen
width and height.
Measuring the angle between the face of the RED-m Eye Tracking
Device and the PC monitor or Laptop screen.
See Geometry Settings for Desktop PCs, Geometry Settings for
Laptops and Setting Angle Measurements.
9. You may need to adjust the sitting position of the user. See Using the
Eye Tracking Monitor.
10.The RED-m Eye Tracking Device needs to be calibrated and validated
with the user who will be using the Eye Tracking System. This ensures
the RED-m Eye Tracking Device is accuratelytracking where the user is
looking on the screen. See Calibration Settings.
The RED-m Eye Tracking System is now readyfor Eye Tracking
experiments.
