IR Markers can be placed in almost every position
(e.g. upside down, sideways, angled), as long as
the front is facing the participant and the IR Marker
reference points (measured from the IR illumina­tor) stay on the same plane (see the image below).
Place the IR Markers at an angle pointing towards
the glasses worn by a participant, to improve the
tracking of IR Markers by Tobii Glasses.

Distance guidelines for IR Marker detection:

Maximum distance: 2,5 meter (at a 0 degree angle)
Minimum distance: 60 centimeter (at least 4 IR Markers should be within view of the IR
sensor or Scene camera)

The smallest IR Marker detection range (using the minimum size AOA: 4 IR Markers, at
10cm apart) is shown in the image. This minimum detection range can be widened by
adding pairs of IR Markers next to, above or below the current AOA.
Add a set of at least 4 extra IR Markers pointing outwards (not in one line) to increase
the angle of detection. The maximum range distance will still remain 2,5 meters.

Make sure the glasses do not move

around on the head and are not removed

during testing & calibration.

Always use the supplied headband

to get accurate results.

An AOA is any area visible within the frame of the scene camera that contains at
least 4 IR Markers. For analysis of distances between 1-2 meters/3.3-6.6feet
from the AOA (optimal range for IR Markers), it’s recommended to mount IR
Markers anywhere within the AOA at minimum 20 centimeters apart. When a
participant will get closer (<1meter/3.3feet), IR Markers might drop from view of
the IR sensor and scene camera. To avoid losing IR Marker Coverage during a
test: Make sure to have at least 4 extra markers closer together around the center
of your AOA with a mutual distance of minimum 10 centimeters.
Do not move the IR Marker Holders during a study!

Make individual snapshots of the different distances at which IR Markers will
show, including at least 4 IR Markers in each snapshot or use a single snapshot

AOA

(A) How to define an Area Of Analysis

Before the recording

Follow these Steps:

(see the User Manual for more detailed
instructions)

1. Charge the Batteries

2. Charge the IR Markers

3. Define an Area of Analysis (A)

• Note down the position and ID number of

each IR Marker Holder on the AOA

Optional: Make a Snapshot of the AOA´s

with a digital camera, or choose to do
this with the built in scene cam later.

4. Insert Battery

5. Insert Memory card

6. Mount the appropriate nose pad to the
glasses

7. Turn the Recording Assistant on

8. Check the battery and memory

9. Make a Snapshot of the AOA´s with the
Tobii Glasses scene camera (B)

• On the Recording Assistant, open the

scene camera: Main menu>Camera

• Make a Snapshot, including the whole

AOA with at least 4 IR Markers

• Save the Snapshot and make additional

snapshots for each AOA in the test

10. Use the glasses with the supplied
headband

Use an IR Marker without a holder, the LED should turn green during the calibration procedure.

Hold the IR Marker at 1 meter distance against a flat surface.
The front of the IR Marker should face the glasses and should not be covered!
Ask the participant to follow the IR Marker with his/her eyes whilst keeping his/her head still during
the entire procedure.

(virtual calibration plane)

(E) How to perform a calibration

Move the IR Marker over a flat surface
to move the dot on the Recording
Assistant display over the different
calibration points of the virtual calibra­tion plane, stop on each point until it
turns green.

Making the recording(s)

Follow these Steps:

Create a new session for each participant or
different task, for easy analysis of the data.

First recording? Make a trial recording first! 1.

Log participant data and related session 2.
information (e.g. session number, duration)
in a Research Log

Optional: Calibrate (instead of after a recording)

Do not take the glasses off between recording
and calibration

3. Record (C)

• Track Status

• Recording

• Pausing and continuing with a recording

• Stop&Save recording

4. Calibrate (before or after recording) (D)

• Track Status

• Calibration (E)

• Accept calibration

5. Repeat step 1-5 for additional recordings

• Check the battery status & memory card sta­tus in between recordings. Replace in time!

• Replace IR Markers that indicate a low battery!

Optional: Hot swapping the battery
Hot Swapping will save time and power, since
no reboot is required.

• Connect the power adapter before swapping

the battery!
Optional: Changing the Memory card between
recordings

• Turn off the Recording Assistant

• Change the Memory card and store it safely

(C) Recording

Track Status
(before recording & calibration)

Wait until the pupil is found
automatically. a dot represents a
found pupil (this should be within
the red border), the color of this
dot and the score on the right
both indicate the tracking quality,
a green dot and a score from 3-5
(5 being a perfect fix on the pupil)
indicates the pupil is found, you
can then select Continue (Right
selection key) to start recording.
