stereotypy
Stereotypy
  • Any non-functional repetitive behavior
  • Two main causes for stereotypy
    • Lack of sensory feedback
    • Lack of cognitive feedback
  • Methods of control Stereotypy

Body Rocking is the most prevalent stereotypy for people who are blind and visually impaired

proposed solution

Rocking

Z

Non - Rocking

Y

Rocking action can be recognized with an accuracy of 94% within 2 seconds

X

Behavioral Psychology literature shows that one rock action is approximately 2.2 seconds long. Effectively, recognizing a rocking behavior well within one rock cycle.

Initial Estimate

Motivation: Weak Temporal Redundancy

Motivation:ComplexObject Structure & Abrupt Motion

Approach: Deterministic Search over a small probable search space (Histogram of Gradients with Chamfer Match)

Approach: Stochastic Search over

a large search space (Color Histogram Comparison)

Result: Approximate Estimate

Result: Accurate Estimate
