2.5 Emergency
Do not rely on the device for emergency calls or banking transactions. We recommend having multiple ways to com-
municate in emergency situations. Banking transactions should only be carried out with a system recommended by,
and approved according to the standards of, your bank.
2.6 Infrared
The Tobii Dynavox I-Series+ emits pulsed infrared (IR) light both from the eye tracker and from the Environmental
Control Unit. Other devices controlled by IR or susceptible to disturbance by IR light might be affected by the IR light
emitted from the Tobii Dynavox I-Series+. Do not use the Tobii Dynavox I-Series+ in the vicinity of such devices if
their functionality is of critical importance.
2.7 Epilepsy
Some people with Photosensitive Epilepsy are susceptible to epileptic seizures or loss of consciousness when ex-
posed 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.
A person with Photosensitive Epilepsy would also be likely to have problems with TV screens, some arcade games,
and flickering fluorescent bulbs. Such people may have a seizure while watching certain images or patterns on a mon-
itor, or even when exposed to the light sources of an eye tracker. It is estimated that about 3-5% of people with epi-
lepsy have this type of Photosensitive Epilepsy. Many people with Photosensitive Epilepsy experience an "aura" or
feel odd sensations before the seizure occurs. If you feel odd during use, move your eyes away from the eye tracker.
2.8 Electricity
Do not open the casing of the Tobii Dynavox I-Series+ device, since you may be exposed to potentially hazardous
electrical voltage. The device contains no serviceable parts.
2.9 Child Safety
The Tobii Dynavox I-Series+ are advanced computer systems and electronic devices. As such they are composed of
numerous separate, assembled parts. In the hands of a child certain of these parts have the possibility of being sepa-
rated from the device, possibly constituting a choking hazard or another danger to the child.
Young children should not have access to, or the use of, the device without parental or guardian supervision.
2.10 Environmental Control
The GEWA Programmable IR Remote Control — Environmental Control Unit (ECU) is not to be relied on as the only
method of interaction with IR controlled devices.
2.11 Gaze Interaction
Some people may experience a certain amount of fatigue (due to intentional eye focusing and hard concentration) or
even a dryness of the eyes (due to less frequent blinking) when first getting used to Gaze Interaction. If you are experi-
encing fatigue or dry eyes start off slowly and limit the length of your Gaze Interaction sessions to your comfort level.
Remoisturizing eye drops can be helpful to combat dryness.
