Page 5: 1 Introduction
1 Introduction 1.1 Overview Tobii Pro Spectrum can be used in various setups, either with an attached monitor or as a stan- dalone unit, to perform eye tracking with physical objects. It supports research investigating blinks and eye closure dynamics, based on raw pupil and eye openness signal data (for example, con- striction/dilation velocity, lid closure rate and acceleration). The eye tracker's design enables the subject to move naturally during recording while still achiev- ing high accuracy and precision. In 2022, Tobii introduced Eye Tracking modes so that research- ers can choose between human and nonhuman primate modes. Read more about Nonhuman primate modes. Figure 1. The typical setup is using Tobii Pro Spectrum connected to a PC that is running Tobii Pro Lab. 1.2 Basic operating principles Tobii Pro Spectrum use infrared illuminators to generate reflection patterns on the corneas of the subject’s eyes. These patterns, plus other visual data about the subject, are collected by image sensors. Sophisticated image-processing algorithms identify relevant features, including the eyes and the corneal reflection patterns. Complex mathematics is used to calculate the 3D position of each eyeball and the gaze point on the screen (or when a screen isn’t used, for the gaze point on the object); in plain words, it tells you where the subject is looking. Eye trackers from Tobii Pro are designed for use in indoor office environments and for tracking on humans. 1.3 Product versions Tobii Pro Spectrum is available in three product versions: 1200 Hz, 600 Hz, and 300 Hz. The values denote the eye tracker’s maximum sampling frequency, but it can be used at lower set- tings as well. The 600 Hz and 300 Hz versions can be upgraded to a faster version. For more information, contact your sales representative or visit Tobii online. Tobii Pro Spectrum User Manual v 2.9... -

3 Safety 3.1 Mounting warning Tobii Pro Spectrum should be mounted according to the instructions of the approved mounts used. Tobii AB or its agents are not liable for damage or injuries to a person or its property due to Tobii Pro Spectrum falling from a mounted configuration. The mount- ing of Tobii Pro Spectrum is done entirely at the user’s own risk. 3.2 Emergency warning Tobii Pro Spectrum is to be used for data collection purposes only. Be aware that due to the low, but possible risk of failure or distraction, Tobii Pro Spectrum should not be relied upon or used in dangerous or otherwise critical situations. 3.3 Epilepsy warning Some people with photosensitive epilepsy are susceptible to epileptic seizures or loss of consciousness when exposed to certain flashing lights or light patterns in everyday life. This may happen even if the person has no medical history of epilepsy or has never had any epileptic seizures. A person with photosensitive epilepsy would also be likely to have problems with TV screens, some arcade games, and flickering fluorescent bulbs. Such people may have a seizure while watching certain images or patterns on a monitor, or even when exposed to the light sources of an eye tracker. It is estimated that about 3-5% of people with epilepsy have this type of photosensitive epilepsy. Many people with pho- tosensitive epilepsy experience an “aura” or feel odd sensations before the seizure occurs. If you feel odd during use, move your eyes away from the eye tracker. 3.4 Infrared warning When activated, Tobii Pro Spectrum emits pulsed infrared (IR) light. Certain medical devices are susceptible to disturbance by IR light and/or radiation. Do not use Tobii Pro Spectrum when in the vicinity of such susceptible medical devices as their accur- acy or proper functionality could be inhibited. Tobii Pro Spectrum User Manual v 2.9... -

Page 23: 8 Additional Features
Available in: Tobii Pro Lab, when selecting the Calibration stimuli in the Design Timeline Tobii Pro SDK, when using screen-based calibration class/methods 8.1.2 Monocular calibration Tobii Pro Spectrum’s monocular calibration functionality lets you to collect eye tracking data optimized for each of the eyes of the participant. Tobii Pro Spectrum can robustly identify the left and right eyes, irrespective if only one eye or both are visible to the eye tracking sensors. For increased confidence in some cases, you could choose to cover the eye that is not tracked, but this is not required. This functionality is useful if one eye causes the binocular calibration process to fail. This could happen, for example, due to severe strabismus, or if one eye is a prosthetic. Separate calibration for the two eyes is also useful for research into binocular coordination and fixation disparity, or in situations where you would like the calibration to pass even if only one eye could be tracked. Note that a default calibration is used for the eye that was not selected for calibration or that has failed to calibrate. During the recording, Tobii Pro Spectrum will continue to search for both eyes because it is less likely to find data for the uncalibrated eye. Nevertheless, Tobii Pro Spec- trum will report the data for the uncalibrated eye when available. Tobii Pro Spectrum allows for two types of monocular calibration: Both eyes Only one eye – left or right Tobii Pro Spectrum User Manual v 2.9... -
Page 24: Use The Ttl Input Port For External Event Recording
Calibrating only one eye at a time: Using the Monocular calibration functionality lets you calibrate only one of the participant´s eyes, while ignoring the other eye. In this case, a calibration is successful if enough data has been collected for the eye of interest and the other eye is ignored. The calibration results report how good the calibration was for the eye of interest. If the data is not good enough for your research, you can improve a calibration by redoing the entire calibration or recalibrating the points with missing data for the eye of interest. Proceed with calibrating the other eye if desired. Available in: Tobii Pro Eye Tracker Manager, when selecting Calibration mode you can choose between: Both eyes, Right eye or Left eye Tobii Pro SDK, when using Screen based Monocular calibration class/methods For more information on how to calibrate Tobii Pro Spectrum using Tobii Pro Eye Tracker Man- ager, read the Learn article, Performing a monocular calibration with the Tobii Pro Spectrum. For more information on the Binocular and Monocular calibration using Tobii Pro SDK, visit the Tobii developer site. 8.2 Use the TTL input port for external event recording Tobii Pro Spectrum is equipped with a digital data input port that records events in up to eight par- allel TTL signals. The events are recorded with a timestamp accuracy better than 50 µs. The detected events are available in decimal format (0–255) through either Pro Lab or Pro SDK. The TTL signal can be combined to obtain up to 256 different events. Any digital signal source fulfilling the electrical specification can be connected to the tracker, for example the Cedrus Stimtracker. Interface: 8-bit parallel TTL input (DBc9) TTL levels: Vin <0,8 V=>; Vin > 2 V => Logical 1 Pinning: pin 1-8: inputs; pin 9: GND Input voltage interval: 0-5 V Tobii Pro Spectrum User Manual v 2.9... -
Page 25: Eye Images
Input configuration: inputs (pin 1-8) are connected to pull up resistors and are opto-isolated. 8.3 Eye images Eye images are available in 5 Hz from Tobii Pro Spectrum eye tracker. Each eye tracking cam- era provides a 5 Hz image stream. During tracking mode (i.e., when the eye tracker detects eyes), the image resolution is 496 x 175 px, except for 1200 Hz when the resolution is 384 x 105 px. During gaze recovery (i.e., when the eye tracker does not detect eyes), the image resolution is 640 x 512 px. The eye images are accessed via Tobii Pro SDK. They are also visible in Tobii Pro Eye Tracker Manager. 8.4 Eye openness Tobii Pro Spectrum provides a raw, unprocessed eye openness signal. The eye openness data is provided in mm, for the left and the right eye individually, at the same frequency as the gaze. (For example, in 1200 Hz when the eye tracker’s frequency is set to 1200 Hz and 600 Hz when the fre- quency is set to 600 Hz.) The eye openness signal can be used independently of the other signals. The timestamp of the eye openness signal will match those in the gaze stream, as they are based on the same eye images. The eye openness signal is available in firmware (FW) version 2.6.1 or later. It also requires Tobii Pro SDK version 1.10 or later. 8.5 Eye tracking mode Tobii Pro Spectrum provides m odes for different groups of nonhuman primate species, due to vari- ations in facial and eye features. Available modes are human, great ape, monkey, and small mon- key. Each nonhuman primate mode is described in the Appendix Nonhuman primate modes. The eye tracking modes monkey and great ape are available in FW version 2.6.1 or later and requires Tobii Pro SDK version 1.10 or later. Eye tracking mode small mon- key is available in FW version 2.9.0 or later and requires Tobii Pro SDK version 1.11 or later. Tobii Pro Spectrum User Manual v 2.9... -

Page 33: Appendix B Recommended Monitor
Appendix B Recommended monitor Tobii Pro Spectrum is supplied with a thoroughly tested and approved 23.8” 16:9 LCD monitor. Our recommendation is to use this monitor, which has been tested for weight, dimension and center of gravity for the system set up with the eye tracker unit and screen mounting solution. If you need to use a different monitor, we recommend that you choose a black monitor without any colored décor elements and that the screen bezel is as slim/thin as possible. No connections or buttons should be located underneath the monitor as this could interfere with the mounting of the eye tracker. The monitor must be equipped with a standard 100 x 100 mm VESA mounting inter- face on the back and it should not weigh more than the supplied monitor. The eye tracker has undergone tipping tests with the supplied monitor attached. If you choose to use a different monitor, Tobii cannot guarantee the safety of such a com- bination and you will use it at your own risk. Tobii Pro Spectrum User Manual v 2.9... -
