Does Eye-Tracking cause the user physical discomfort?
No, not with proper use of the system. However, there are some precautions that the user should take. There are two types of strain that can occur from using eye-tracking devices: neck strain and eye strain. If you notice discomfort, pain, or fatigue in either of these areas, stop using EyeMax and rest until you feel well again. The length of time that a person can use the EyeMax before feeling strain or fatigue varies from person to person. You need to listen to your body and rest when it tells you. This is true for all eye-tracking systems, and for all computer monitor users. Recommendations for alleviating such monitor eye strain. Trying out an eye-tracking system may initially be fatiguing to a new user. This may be because they tend strain their eyes to reach and concentrate upon each target until they become more relaxed in the operation of the system. A typical user shortly gets used to eye-tracking and their use of the system will soon become less fatiguing.
