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.

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

3rd TASK: FILL OUT THE MISSING PARTS

CURRENT & FUTURE WORK

• EXECUTE THE STUDY WITH 20 SUBJECTS,

• DEVELOP AN AWARENESS SYSTEM FOR “BUSY PARENTS”.
