2. Challenges to deploy a sensing campaign  Deciding the granularity of the sensed information Components that collect low-level data vs high-level data  Calibrating the sensing components to the population to be monitored. To the particular participants characteristics Indicating a calibration criteria  The target users are researchers with little or no technical background Developing a tool for behavioral data collection from mobile phones to enable researchers with low technical skills to implement a sensing application: InCense

3. InCense implementation model  Session: group of components connected to achieve a sensing goal.  Sensors: act as interfaces with the mobile phone’s sensors  Filters: preprocess raw data from sensors  Survey: multiple choice or open- ended questions  Triggers: start sessions if certain conditions are met  Sink: data pool wherein the sensed information is assembled into files

8. Scenario:  “A public health organization (PHO) is interested in comparing the walking habits of older adults in the winter and in the spring. They began using InCense for data gathering from 392 individuals during two weeks in the middle of January, and then again in May. The application captures the individual location, the activity level obtained from the accelerometers. A filter infers from the GPS and accelerometer, if the individual is walking or in a vehicle as he leaves his home. When InCense detects that the user is back at home, the mobile phones, will ask the individuals to complete a survey with question related to the activity being performed and their wellness. The data captured from the individuals is sent to the PHO to find interesting correlations with standard statistical packages.”
