Experiment

• Independent Variable
• Interface Design
• Realistic
• Form-based

• Dependent Variables
• Speed of task completion
• Subjective satisfaction

Hypothesis The realistic interface will yield
longer task completion times than the form-based
interface, but will rate higher subjectively.
Subjects 22 undergraduate UMD students with
varying levels of computer experience

1. How would you rate the interface overall
Poor (1) -- Excellent (9) 2. The interface was
Confusing (1) -- Straightforward (9) 3. The
interface was Unattractive (1) -- Attractive
(9) 4. The interface was Visually distracting
(1) -- Visually non-distracting (9)

Summary of Results

• The realistic interface did not result in
  statistically greater task completion times

• The realistic interface was perceived as being
  more visually attractive than the form-based
  interface

• The realistic interface was not perceived as less
  confusing, less distracting or better overall
  than the form-based interface

Conclusions

• Impact for Practitioners
• Use in home/office/entertainment applications,
  where subjective satisfaction is important.
• Use in life-critical and industrial applications
  if it does not increase design time/cost.

• Suggestions for Future Researchers
• Avoid a within-subjects design
• Larger population sample

• Refined Theory
• Performance time for realistic interface is not
  appreciably greater than for form-based
  interface.
• Users prefer the realistic interface visually.
