We are currently looking at ocular fixation using the Skalar Limbus tracking
device. One of the parameters that we intend measuring is the mean fixation
time. Has anyone looked at this using the Slaral Limbus system (or somthing
similar). If so, how have you defined when the eye is fixating either on or
off target. HAve you used a velocity threshold e.g. fixation ocurrs when the
eye velocity is less than X deg/s
Comments/advice welcome
