With the eye tracker, the eyefixation and fixation time distribution in different speeds are analyzed when the car passes through traffic signs with different font height.
Two experiments were designed to examine the pattern and duration of eyefixation as subjects interpreting line graphs to explore the underlying cognitive process of graph comprehension.
Not showing the normal preference for eyefixation may also affect a child's social growth by lowering a child's ability to interpret and react to emotional cues communicated by the eyes.
