    2. Outline Introduction Related works System overview Implementation Evaluation Discussion Conclusion

    3. Introduction AndWellness: a personal data collection system for activity and experience sampling. Area of usage: health and behavior monitoring Example: Cancer Survivor Study by UCLA measures the behaviors and emotions of young breast cancer survivors. Collect daily information on: nights sleep, various emotional feedback, behaviors remind users to take simple saliva sample to measure various biomarkers.

    4. Introduction In the past: asked participants to recall events used paper diaries to log events employed automated telephone systems to record data recently used PDA or wireless mobile devices to log data

    5. Introduction The trend: moving towards a real time assessment of human behavior Because factors can and do affect the memory of participants recalling past experiences (Recall bias): current emotional state length of time asked to recall participant sitting in a foreign environment Alleviate the issue by having participants record events as they happen or immediately thereafter

    6. Introduction Challenges with experiences sampling studies: Time and resources for developing robust data collection systems from scratch Data collection systems should allow researchers enough control to: measure a participant’s timely adherence to the process configure when and why a participant is queried

    7. Introduction AndWellness: a personal data collection system, uses mobile phones to collect and analyze data from: active, triggered user experience samples: survey responses passive logging of onboard environmental sensors

    8. Related works Can be divided into two classes: Experience sampling studies Other software systems

    9. Related works Experience Sampling Studies Paper diary: very low upfront cost but costly and labor intensive post-study analysis, can not verify adherence, low motivation to adherence Reminders can help Automated phone system: eliminates problems with data entry (response stored as integer), time stamped responses ensuring adherence Recently, various handheld devices: prompt triggers to remind participants, compliance checks via time stamps
