2.4. Child Safety The EyeControl system is an advanced computer system and electronic device. As such it is composed of numerous separate, assembled parts. In the hands of a child some of these parts may become detached from the device, possibly constituting a choking hazard or another danger to the child. Young children should not have access to, nor use of the device without parental or guardian supervision.
2.5. Infrared Warning When activated, the EyeControl emits pulsed infrared (IR) light. Certain medical and other devices are susceptible to disturbance by IR light and/or radiation. Do not use the EyeControl device when in the vicinity of such susceptible devices as their accuracy or proper functionality could be impaired. Do not use the EyeControl at the same time as another device which uses infra-red lighting or it may interfere with the performance of the device.
2.6. Electromagnetic interference The EyeControl device uses certified products and follows the protocol for electromagnetic devices. In Page 9 of 59
case of electromagnetic interference that may lead to a malfunction, the power button will illuminate red to notify the user that there is an error. If the power button illuminates red, please contact support.
2.7. Epilepsy Warning Some people with photosensitive epilepsy (PSE) are susceptible to epileptic seizures or loss of consciousness when exposed to certain flashing lights or light patterns in everyday life. This may occur even if the person has no medical history of epilepsy or has never had any epileptic seizures. A person with PSE 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 monitor, or even when exposed to the light sources of an eye tracker. It is estimated that 3% to 5% of those diagnosed with epilepsy have this type of epilepsy. Many people with PSE experience an "aura" or odd sensations before a seizure occurs. If you, or the wearer of the head mount, feel odd during use, turn off the device and remove the head mount.

3. Usage Conditions The EyeControl is designed for 24/7 use. and may be worn in conjunction with most other head mounted devices (such as a CPAP). However, some of the following conditions may affect performance.
3.1. Light conditions We recommend that the device be used in a controlled and well-lit environment. Sunlight should be avoided as it contains high levels of infrared light which may interfere with the eye tracking system. Sunlight affects eye tracking performance severely and prolonged exposure to sunlight can overheat the eye tracker. The eye tracker is not designed for exposure to (direct) sunlight. Eye tracking generally does not work in strong direct sunlight. Shielding the eye tracker adequately from the sun may prevent sunlight from interfering with eye tracking.
3.2. Eyelashes Long eyelashes can be obstructive when the user’s eyes are not fully open, especially if the user is wearing mascara. In rare cases, eyelashes may completely block Page 15 of 59
the view of the user’s pupils, making eye tracking impossible.
3.3. Eye Make-up Eye makeup may interfere with the eye tracking capabilities of the device. It is recommended to avoid the application of mascara and eye liner when operating the EyeControl.
3.4. Droopy eyelids Droopy eyelids or otherwise obstructive eyelids can block the view of the participant’s pupils. In rare cases, such eyelids may completely block the view of the participant’s pupils, making eye tracking impossible.
3.5. Eye glasses and contact lenses The EyeControl device may be used in conjunction with standard eye glasses, but reflections on the glass may interfere with eye tracking. Bi-focal lenses may cause interference with the eye-tracker. Standard contact lenses may be worn. Colored or decorative lenses that change the appearance of the pupil or iris should be avoided as they may make eye tracking impossible.

3.6. Color blind The EyeControl device may be operated by a user who is color blind, although there is a possible limitation in the user’s ability to interpret the LED indicators on the main unit.
3.7. Cataracts The EyeControl may be operated by users with cataracts, although there may be a reduction in performance.
3.8. Range of motion limitations The EyeControl device is operated by tracking the user’s left eye. If the user does not have full range of motion with the left eye, the device will be inoperable. The device design requires that the user have full range of eye movement: up, down, right, left and blink. Note: The default operation of the device requires the ability of 5 gestures: up (back), down (select), left (previous), right (next) and blink (speak). However, the user may change the number of gestures which control the device. For more information, please refer to: https://my.eyecontrol.co.il. Page 17 of 59
3.9. Usage while in motion There may be a reduction in performance if the device is used while in motion.
3.10. Power Use an accessible outlet and make sure the cords are properly placed to avoid the risk of tripping. Never use damaged power cords. When possible, we recommend using the device while it is connected to a power outlet.
3.11. WLAN/Bluetooth connectivity WLAN signal quality is affected by different environmental factors such as the distance between the main unit and the router, the presence of walls, windows, furniture and other objects, and the presence of other WLAN devices and networks in the same area. A weak or low-quality WLAN signal will decrease the quality of connection during support mode and while performing software updates. * The EyeControl is compatible with 2.4GHz WLAN networks. Bluetooth signal quality is affected by different environmental factors such as the distance between the main unit and the tablet/computer. A weak or lowPage 18 of 59
