  1. Radial Marking Menu Performance Improvement and User Type Detection • Tim Burke - tburke2@umbc.edu • Prepared for CMSC601

  2. Radial Marking Menus

  3. Why?

  5. Related Work - Performance • Andy Cockburn, Carl Gutwin, and Saul Greenberg, “A Predictive Model of Menu Performance,” ACM SIGCHI Proceedings, 2007. • Amy Hurst, Scott E. Hudson, and Jennifer Mankoff, “Dynamic Detection of Novice vs. Skilled Use Without a Task Model,” ACM SIGCHI Proceedings, 2007.

  6. Background - Predictive Model • “Morphing Menus” change over time in response to user • Yields a 12% to 25% reduction in selection time of frequently used commands even when factoring out user memorization

  7. Background - Dynamic Detection • Dynamic user type detection through trained C4.5 decision tree statistical classifier • Novice and expert users differ in needs when interacting with software • Achieves 90%+ detection accuracy with proper training data

  8. Experiment • Two experiments: • Menu adaptation through “morphing menu” concept from Cockburn experiment to radial marking menus • Build dynamic detection classifier from Hurst experiment by collecting training data and testing for accuracy with radial marking menus

  9. Test Application

  10. Evaluation • Menu Adaptation Experiment • Statistically significant reduction in menu selection times as compared to baseline tests with static, unchanging menus • Dynamic Detection Experiment • Once trained, is the classifier able to detect the user as novice or expert with accuracy approaching that of the previous experiment (approaching 90% accuracy)

  11. Conclusion • Radial marking menus poised to become more popular • Understanding ways to better leverage them to provide a more powerful user experience
