On Safety
Read this manual carefully before connecting and using
the eye
tracker
The Tobii T60 and T120 Eye Trackers are intended only for use in office and home environments.
Safety of NIR illumination from the Tobii T Series Eye Trackers
The illuminators of the Tobii T Series Eye Trackers have been tested at ETL SEMKO, Stockholm,
according to IEC/EN 60825-1/A1-A2. The test has shown that the products comply with the standard
for IEC/EN 60825-1/A1-A2 class 1 LED products intended to be used for long time exposure.
The standard IEC/EN 60825-1/A1-A2 states an Accessible Emission Limit (AEL) for continuous long
time exposure. This limit is the maximum illumination that a person should be exposed to for eight hours
a day many days in a row.
The products are intended to be used by a subject at a distance of approximately 60 cm from the eye
tracker. At the regular user distance the exposure, averaged over time, of light from the Tobii T60 and
T120 Eye Trackers to the subject sitting in front of it is 0.1 % of the allowed limit for long time exposure
according to IEC/EN 60825-1/A1-A2 class 1 LED products.
Epilepsy warning
Some people with Photosensitive Epilepsy are susceptible to epileptic seizures or loss of consciousness
when exposed to certain flashing lights or light patterns in everyday life. This may happen even if the
person has no medical history of epilepsy or has never had any epileptic seizures.
Such people may have a seizure while watching certain images or patterns on a monitor, or even when
exposed to the light sources of an eye tracker. It is estimated that about 3-5% of people with epilepsy
have this type of photosensitive epilepsy.
Do not open the eye tracker!
Non-compliance will result in loss of Warranty! There are no user serviceable components inside and the
risk of electric shock is high due to the presence of Dangerous High Voltages. Contact Tobii support if
your eye tracker is not working properly.
All Tobii Eye Trackers are CE-marked, indicating conformity with the essential health and
safety requirements set out in European Directives.
