  2. Scope of this dissertation Multimedia Technologies • Interactions between individuals • Physically isolated. • Sensory deprived. • Sensory overload. • Communication breakdown. • Evidence-based understanding of the social interaction enrichment technologies • Work on this

  3. Social Interactions Social Situational Awareness Face Body Social Cognition Social Reciprocation Social Hearing Voice Social Sight Social Touch Social Stimulation Social Stimulation Social Cognition Social Reciprocation

  4. SSA in Various Settings Remote Collaborations Social Assistance Decision Making TeamSTEPPS • Expressing Opinion • Managing Conflict • Making Decision • Speed of Decision • Interaction with Colleagues • Difficulty Establishing Rapport • How many people? • Where are they located? • What are their facial expressions? • Eye Gaze • Eye Contact • Body Mannerisms • Leadership • Mutual Support • Communication • Attitude • Situation Monitoring • Patient Safety

  5. Group Vs. Dyadic Interactions

  6. Case Studies of People who are Blind

  7. Self-Report Importance of Non-Verbal Cues Focus Group on 8 Social needs • 27 participants - 16 blind, 9 low vision and 2 sighted specialists.

  8. Contributions from this Dissertation Future work Focus 8 8 6 7 7 6 Ground Work in Social Assistance 3 5 Importance 1 4 3 2 5 2 1 4 High Feasibility

  9. 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

  10. 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.

  11. Social Gaze & Interaction Space Interpersonal Space 1.5’ 4’ 12’ 25’ 0’ Intimate Social Public Personal

  12. Modeling Distance & Direction through Face Detection Module 1: Color Analysis Module 3: Evidence Aggregation Module 2: Markov Random Field LPCD

  13. Structured Mode Searching Particle Filter (SMSPF) Step 1 Step 2 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 Example Search Windows Corrected Estimate
