Influences of data filtering on human-computer interaction by gaze-contingent display and eye-tracking applications

摘要: We describe an interactive gaze-contingent display (GCD) applied to clinical applications; the system uses a simple texture hole inhibit peripheral vision, test and stress overt mechanisms of visual searching in normal subjects. The correct use GCD vision research is affected by tremor hole, due noise, nystagmus, eye blinking, calibration subject reactivity. These issues compromise execution task. In order obtain stable we implemented predictive (PGCD), fitting through dispersion fixations modulating filter. paper describes PGCD compare it with common technique, providing evidence that humans fit exploration based on characteristics computer system; particular found significant difference applying or finite impulse response suggest human-computer interaction neuropsychological context must be developed taking consideration both technical point view human behavior.
