INDEX
• Background info:– Goals of my PhD project,– Achievements,– Experience Sampling Method (ESM),– Day Reconstruction Method (DRM),
• Application
OVERALL GOAL
• How can Awareness Systems support intra-family communication?
Awareness Systems
• Awareness Systems are a class of CMC systems having as a goal to help people keep in touch about their activities and whereabouts over long periods of time.
EXAMPLES OF AWARENESS SYSTEMS (1/2)

MY FOCUS
• Communication between “busy parents”
• Couples:– Both working,– Have at least one dependent child,
• Goal is to support their communication with Awareness Systems
PROBLEM
• Communication needs of “busy parents” are dynamic and changing with their context,
• How to capture those needs?
METHODS ALREADY USED
• Interview study,
• Online survey study,
• Common problem=> lacking flexibility to fit into the life events of participants.
Experience Sampling Method
• A quasi-naturalistic method that involves signaling questions at subjects at random times throughout the day.
Day Reconstruction Method
• Subjects first revive memories of the previous day by constructing a diary consisting of a sequence of episodes,
• Then they answer the research questions thinking about the episodes.
• Assess how people experience their various activities and settings of their lives.
BOTH METHODS HAVE SHORTCOMINGS
• ESM: interrupting the subject from daily activities, asking at inconvenient moments, => loose valuable data
• DRM: difficulty in remembering occurred events => weak accuracy, unreliable data.
GOALS OF ESM & DRM STUDY
• Find out what information are parents willing to automatically share among themselves,+ under which context,
• Evaluate the combined method.
OVERVIEW OF THE STUDY
• INITIAL TASK (WEBSITE): – Info willing to automatically share with partner,
– Places and activities (during a typical working day),– Link the info selected to context (place & activity)
• 5 TYPICAL WORKING DAYS (WEBSITE & PDA):– Ask at random times about context (at that time) & info willing to automatically share.
FILTER INFO THAT A PARTICIPANT WOULD GENERALLY WOULD BE WILLING TO SHARE
WITH PARTNER
CONTEXT (PLACES) DURING A TYPICAL WORKING DAY
CONTEXT (ACTIVITIES) DURING A TYPICAL WORKING DAY
LINK INFO TO CONTEXT
LINK INFO TO CONTEXT
ANSWER QUESTIONS ON THE PDA

3rd TASK: FILL OUT THE MISSING PARTS
CURRENT & FUTURE WORK
• EXECUTE THE STUDY WITH 20 SUBJECTS,
• DEVELOP AN AWARENESS SYSTEM FOR “BUSY PARENTS”.
