The Argus II eye prosthetic captures images through a camera positioned on the wearer's face.
Fortunately, people in a state of drowsiness produce several visual cues that can be detected in the human face, such as (i) yawn frequency, (ii) eye-blinking frequency, (iii) eye-gaze movement, (iv) head movement, (v) facial expressions. .
The general scheme of both systems is shown in Figure 1, where six modules are presented as follows: (i) face detection; (ii) eye detection; (iii) face tracking; (iv) eye tracking; (v) drowsiness detection; (vi) distraction detection. .
Initial fixations (initial orienting) 20 met the following requirements: (i) gaze was fixed on the central cross before drink stimuli appeared, (ii) eye movement occurred ≥100 ms after the drink stimuli appeared and (iii) eye movements occurred towards the AOIs.
In addition to these main stimulus conditions, the experimental protocol also included three types of pure rotation conditions for both leftward and rightward directions: (i) eye pursuit over a black background (with the projector on), (ii) eye pursuit over a static field of dots, and (iii) pure rotational optic flow in a 3D cloud (simulated rotation-only).
Cryocoagulation was performed for peripheral iatrogenic tears (n = 10; group I: three eyes, group II: five eyes, group III: two eyes).
As the nation marched off to both World War I and II, all eyes and focus turned to the war effort, as those at home supported soldiers overseas.
Interestingly, group III revealed minimal area of cataract distribution on treatment with 200 mg/kg body weight of C-PC compared to group II rat eye lens.
The Eyelink II video eye tracker was used; it consisted of infra-red cameras (CMOS sensors).
The abnormality of the background EEG during the ERP recording session in stage II non rapid eye movement (NREM) sleep was classified as either moderate, severe, or hypsarrhythmic.
