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
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
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
