  1. MEASURING AWARENESS AND DISTRACTION CAUSED BY CHANGE IN INFORMATION DENSITY A Semester project by MAULIK SHUKLA DENZIL JOHN AJAY JAMPANI Project Advisors: DR. CHRIS NORTH DR. SCOTT McCRICKARD

  2. CONTENTS • MOTIVATION • EXPERIMENTAL SET UP • METHODOLOGY • SUBJECTS • FINDINGS • CONCLUSION • FUTURE WORK

  3. MOTIVATION • Understanding the effects of information density on one’s ability to perform primary task • Awareness caused by a change in information density • Related work - SOMERVELL et al. “Measuring awareness and distraction caused by textual and graphical displays in the periphery”

  4. EXPERIMENTAL SET UP • Primary Task: Computer Simulated Game • Secondary Task: Pictures of Varying Density

  5. PICTURES OF DIFFERENT DENSITY LEVELS • DENSITY RATIO 16:4:1 (FOR ALL PURPOSE) HIGH (320) MEDIUM (80) LOW (20)

  6. METHODOLOGY • Three Groups - Only game - Only picture - Game + Picture • Three Rounds • Three Density Levels In changing order - Low Mid High - Mid High Low - High Low Mid

  7. SUBJECTS

  8. RESULTS

  9. CONCLUSIONS • No significant effect of information density on primary task performance – It is just presence of secondary task that makes the difference • No significant effect of change in density on secondary task performance • Count and Identify tasks are better at low densities and Pattern and Group tasks are better at high densities

  10. FUTURE WORK • Make the primary and secondary task more realistic • More weightage to the errors in primary task • Time based analysis of effect of information density on primary task

  11. THANKS • Special thanks to JACOB SOMERVELL for system integration • STUDENTS OF 2604 and all other FRIENDS who participated in the experiment
