Optical Safety of Infrared Eye Trackers Applied for Extended-Durations
To review the potential optical radiation hazards from infrared eye-tracking systems when exposure durations are continuous throughout the day. Emphasis is placed upon the use of eye-tracking for gaze-based communication for severely disabled persons, which requires exposure of the eyes throughout a day over many years. Although there exist exposure guidelines from the International Commission on Non-Ionizing Radiation (ICNIRP) for infrared exposure and a CIE Standard (S-009) for photobiological safety of lamps and lamp systems, the lengths of exposure employed in this type of interface technology for disabled users may exceed the durations envisioned in the current exposure guidelines and standards. Abnormalities in the eye behaviour of severely disabled users may also require special treatment in safety standards.
