In this paper, a hands-free technique for controlling the alteration of endoscope direction using a pupil-tracking method via an image processing method was introduced.
First, the horizontal pupil movement signal was extracted from the infrared video data using a pupil extraction method.
Eye position was monitored using an infrared pupil tracking system (ISCAN, Inc .. Functional and anatomical data from both human and monkey subjects were preprocessed and analyzed using FreeSurfer and FS-FAST (version 5.3; http://surfer.nmr.mgh.harvard.edu/ (Fischl 2012).
So we'll invest in the early years, help put troubled families back on track, use a pupil premium to make sure kids from the poorest homes go to the best schools not the worst, recognise marriage in the tax system and, most of all, make sure that work really pays for every single person in our country Remember last year?
Here 20 patients with posterior cortical atrophy, 17 patients with typical Alzheimer's disease and 22 healthy controls completed tests of fixation, saccade (including fixation/target gap and overlap conditions) and smooth pursuit eye movements using an infrared pupil-tracking system.
After the WFPTa experiment, the changes in the wavefront aberrations were simulated using the pupil tracking data, the first wavefront slopes measurement and a reference wavefront yielding a mean wavefront RMS of 0.35 ± 0.10 μm (mean error RMS of the simulations was 0.21 ± 0.07 μm); see Fig. 7- d).
The pupil size was recorded from the unilluminated eye using an infrared video pupil tracking system (ViewPoint, Arrington).
The MobileEye system uses Dark Pupil Tracking to compute the x and y coordinates of the pupil within the scene.
Check the tracking force using a tracking gauge.
Pupil diameter modifications were assessed using an eye-tracking system (SMI ETG 1, SensoMotoric Instruments GmbH, Teltow, Germany) (Additional file 1: Fig. S1); heart and respiratory rate and thoracic volume variations were measured using a biometric belt (Hexoskin, Montréal, Canada).
