[−][src]Struct libeyelink_sys::DSAMPLE
@ingroup messaging \brief Floating-point sample with floating point time
The EyeLink tracker measures eye position 250, 500, 1000 or 2000 times per second depending on the tracking mode you are working with, and computes true gaze position on the display using the head camera data. This data is stored in the EDF file, and made available through the link in as little as 3 milliseconds after a physical eye movement. Samples can be read from the link by eyelink_get_double_data() or eyelink_newest_double_sample().
