He also talked about a supposed cold and calculating "Jewish gaze".
However, when the head is rotated, the direct gaze should be calculated on the basis of the relationship between the position of the iris and the degree of head rotation [25].
Eye trackers consist of an infrared camera that films the eye, and software that calculates the gaze position using image processing and geometrical calculations.
To evaluate our main prediction for cognitive performance, we calculated the difference score between the percentage of correct trials in the direct gaze and in the averted gaze conditions, and compared this measure between groups (this is analogous to testing the interaction effect in a 2 × 2 analysis of variance with group and condition as factors).
We calculated the beak orientation within the horizontal plane from the position data of the base and the tip of the beak to estimate gaze direction (see Discussion for the problem of "gaze direction" in birds).
The synthetic functions, which were described in the previous section, are used to calculate the specific gaze-dependent measurement error for any gaze position during sentence reading.
He closed one eye to gaze at the ceiling and beyond, calculating.
Because the gaze similarity values are calculated based on each participant's gaze location on each film frame, the order of frames for each participant (and thus the order of their eye movements across frames) was shuffled.
At each sampling time, for the eye relative to the head (eye), the head relative to the space (head) and the eye relative to the space (gaze), we calculated the harmonic mean of all available data of the infants whose calibration factors were determined.
Or just stare — this was for strangers — his eyes following whoever it was into the candy store, wondering, calculating, assessing as a man alone might do, a man alone and unguarded in the brazenness of his gaze.
