Data Analyses



Eye Movements

  • Several Classes

  • For this talk the important class is the miniature eye movements

  • Several types, e.g.,

    • Microsaccades

    • Jitter

  • Move eyes small distances

  • Jitter is random

  • These eye movements are modeled by randomly repositioning the entire figure a small distance over the array of receptive fields a small number of times and taking the average.
