1. A computer-implemented method of using an infrared eye-tracker camera of a handheld eye-tracker console that is wirelessly controlled by an operator-side handheld computer physically untethered from the handheld eye-tracker console, the method comprising:
wirelessly connecting the handheld eye-tracker console with the operator-side handheld computer via a cloud server that provides wireless communication between the operator-side handheld computer and the handheld eye-tracker console while both a display screen and the infrared eye-tracker camera of the handheld eye-tracker console are mechanically mounted together and oriented in a same direction and while the operator-side handheld computer is portable to different locations relative to the handheld eye-tracker console;
during said wireless communication between the operator-side handheld computer and the handheld eye-tracker console via the cloud server and in response to a command input at the operator-side handheld computer while a patient is oriented toward the handheld eye-tracker console, operating the infrared eye-tracker camera mounted adjacent to a periphery of the display screen of the handheld eye-tracker console to convert infrared-detected eye movements of the patient into a real-time data stream that includes pupil positions and gaze vectors during display of a predetermined sequence of stimulus videos on the display screen of the handheld eye-tracker console; and
subsequent to said operating the infrared eye-tracker camera of the handheld eye-tracker in response to the command input at the operator-side handheld computer, automatically uploading to the cloud server without human intervention both a first file storing timestamped eye-tracking gaze coordinate data of the patient collected during the display of the predetermined sequence of stimulus videos and a second file storing a playlist of the predetermined sequence of stimulus videos and associated timestamps of the predetermined sequence of stimulus videos.
