  1. Augmented Reality Effects in JAUS Subsystem Commander Teleoperation Interfaces Problem areas with AGV teleoperation interfaces: - Communication - High-overhead - Poorly Designed - Outdated technologies Gregory Garcia Center for Intelligent Machines and Robotics Dept. of Mechanical and Aerospace Engineering University of Florida December 2008

  2. Existing Interface

  3. Functional Demonstration

  4. User Study Conditions • Apparatus: • Quiet Room (2 days) • Laptop Computer (15.4 inch 1280x800 display) • Optical Mouse • Experimental and control Interfaces • Study Protocol: • 5 minute tutorial and Q/A (2x) • Interface Evaluation (2x) • Questionnaire • Metrics: • Quantitative • Error Rate • Decision making time • Qualitative • Situational Awareness • Interaction Style • Eye Gaze • Random testing order • Ease of use • User Confidence • Strengths/ Weaknesses

  5. Results and Analysis • Ho: OERstandard ≤ OERvideo Ha: OER standard > OERvideo • p-value = 0.27996, t’ = 0.58977, tα = 1.69913 • Fail to reject the Null Hypothesis • 28% probability that pattern is due to chance One sided T-test for independent samples w/ unequal variances α = .05 • H0: DMTstandard – DMTvideo = 0 Ha: DMTstandard – DMTvideo ≠ 0 • p-value = 0.2203, t’ = 1.26524, tα/2 =2.08596 • Fail to reject the Null Hypothesis • 22% probability that patter is due to chance Two sided T-test for independent samples w/ unequal variances α = .05

  6. Results and Analysis (2) • Other Observations • Unanimously chose Video interface • Highest marks for ease of learning • Increased User Confidence Level • Color scheme received favorably • Rely heavily on video for initial big-picture, used sensor fusion for details
