1. Introduction
This section introduces the technical capabilities and supporting
documentation for the EyeLink
®
1000 Plus eye tracker. The EyeLink 1000 Plus
can be used in several configurations, each with its own strengths and
capabilities, allowing a single base system to suit a wide variety of research
applications. The same camera technology and software supports all
configurations, making the EyeLink 1000 Plus the most versatile solution for
eye and gaze monitoring available. Each EyeLink 1000 Plus configuration
shares the same application programming interface (API) and EyeLink Data File
(EDF) output, allowing experimenters to seamlessly switch between data
collection and analysis modes that best suit their particular experimental
paradigm or to accommodate different participant populations.
The EyeLink 1000 Plus high-speed camera has been designed to
interchangeably fit into different mounting options (with the exception that an
additional Fiber Optic Camera Head is required with the Long Range Mount).
This means that the purchase of a single Base System plus an array of mounts,
allows the same eye tracker to be used in a wide range of settings from high
precision recording in the laboratory with the head stabilized, through Remote
recording without head stabilization, to sensitive and specialized recording
environments like MRI or MEG settings. In all of these modes the
unprecedented low noise, stability and the world’s fastest sampling rates are
available. The EyeLink 1000 Plus is truly a multipurpose eye tracking solution.
The EyeLink 1000 Plus camera can be affixed to a Desktop Mount that provides
highly accurate monocular or binocular data acquisition at up to 2000 Hz (with
the 2000 Hz camera upgrade) using a chinrest. In addition, the cameras can be
configured in a redesigned Tower Mount that allows highly accurate monocular
or binocular recordings with a wide field of view when the participant’s head is
supported by a chin and forehead rest. A third mounting option is the LCD Arm
Mount that affixes the EyeLink 1000 Plus beneath an LCD monitor on a flexible
arm so that the entire eye tracking apparatus and display can be easily moved
into place in front of the viewer whose eyes are to be tracked. The Long Range
Mount with the Fiber Optic Camera can be used at distances up to 150 cm from
the eye for electromagnetic sensitive environments (e.g., EEG or MEG) or
environments where metal content needs to be minimized (e.g., MEG or MRI).
Finally, the Primate mount provides a mounting option for the camera so that
placement can be out of the way and above the participant, making it ideal for
use in animal recording situations.
