  1. Office Activity Awareness Ian Li Machine Perception Spring 2005

  2. Activity awareness can be good • Awareness of how one uses time in the office can be useful • Manage activities, coordinate interaction with others, and assess your own productivity • But, too much to remember and recording can be tedious

  3. Computers can help • Delegate recording of activity to computers • Can monitor daily • Can store activity for months and years • User can focus on analyzing the information at the end of the day or week

  4. What did I do? • System for office activity detection • Applied system for “productivity” assessment

  5. What is the result? • System can reliably detect activity in the office environment (87%-93%) • System can somewhat match the users’ measurements of their own “productivity” (up to 74%)

  6. The rest of the talk… • System: activity detection • Application: “productivity” assessment • Future work

  7. Sensors for detecting activity Sensors Extracted Features Amount of motion Sound level Using mouse or keyboard? Activities detected Walking Sitting/standing Sitting & talking Not in space Talking Not talking Using mouse Pressing keys Not using computer

  8. Data collection tool

  9. Ground truth for activity detection • Took snapshot every half minute sitting not in space walking sitting & talking? sitting & talking

  10. Activity can be detected accurately • Using microphone and camera features

  11. Applying to productivity awareness • Can we measure productivity by looking at activities? • How aware are people of their own productivity?

  12. Recording productivity • Measurement of productivity • What percentage of the past 15 minutes did you spend actively engaged in a work-related task? • “Experience sampling” technique • Every 15 minutes the timer plays a bird sound Bird sound

  13. Using knowledge of activity is okay for detecting productivity

  14. Using raw features is slightly better for detecting productivity!

  15. Future work • Longer deployment of the system • How many features are sufficient to predict productivity? • Use temporal model (e.g., HMMs) • Activity-oriented vs. task-oriented measurement of productivity • Other applications of activity awareness • Setting goals and monitoring completion of goals

  16. Office Activity Awareness http://www.cs.cmu.edu/~ianl/16899/ will be up by March 13th for more details or contact me at ianli@cmu.edu Ian Li Machine Perception Spring 2005

  17. Acknowledgements • Software development help from Bilge Mutlu and James Fogarty • System deployment participants: Anind Dey, Jason Hong, Bilge Mutlu, and Pedram Keyani
