INDEX
• PhD background info,• Definition of Awareness Systems (AS),• Examples of AS,• Motivation & Study Method,• Results & Conclusions.
OVERALL GOAL
• How can Awareness Systems support intra-family communication?
MY FOCUS
• Communication between “busy parents”
• Couples:– Both working,– Have at least one dependent child,
• Goal is to support their communication with Awareness Systems
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.

NEED OF MORE EMPIRICAL RESEARCH
• Is a constant information flow between parents wanted at all?
• Are there any other communication needs except intimacy?
• Should the information flow be symmetric?
INTERVIEW STUDY RESULTS
• 20 Dutch “busy parents”,
• Results:– While at work, refrain from initiating communication for fear of interrupting,
– Not much need for directly communicating affection,
– Most cases a practical reason is used as a carrier for communicating affection as well.
METHOD
• Through literature review of papers describing AS & our interview transcripts we formed 41 statements representing Awareness Information that can be exchanged.
METHOD: EXAMPLE OF STATEMENT
METHOD: EXAMPLE OF STATEMENT
METHOD: EXAMPLE OF STATEMENT
METHOD: EXAMPLE OF STATEMENT
METHOD: ASKING IN 2 STEPS
METHOD: ASKING IN 1 STEP
METHOD
• 69 participants,• Group 1: 34 in 2 steps,• Group 2: 35 in 1 step.
• H1: When parents are asked in a way representing an asymmetrical exchange of information they would be willing to exchange more information than when asked in a way representing a symmetrical one.
• H2: Parents are willing to receive more information than they are willing to send.
ANALYSIS
• Rerated each of the 41 statements for the 2-step for each participant of Group 1,
• calculated the proportion of participants choosing a statement,
• did a significance interval test at 95% for each statement comparing with the 1-step.
• Did a significance interval test at 95% for both sending and receiving.
RESULTS
• Method: In both cases no statistically significant difference between the two,
• =>There is no difference in asking in a 1 step or 2 steps,
• =>There is a symmetry in communication needs.
CONTENT OF INFORMATION
• Most wanted statements to be shared:
– My spouse is informed that I am wishing him/her a good day,
– My spouse is informed about how I am feeling today,
– My spouse is informed that I do not want to be disturbed now.
CONTENT OF INFORMATION
• Most wanted statements to be received:
– I am informed that my spouse is wishing me a good day,
– I am informed about how my spouse is feeling today,
– I am informed that my spouse does not want to be disturbed now.
LESSONS LEARNED
• Empirical evidence that there is a symmetry in communication needs,
• Empirical evidence of more expressive means for affective communication,
• Informing about availability,
• Combine requirements elicitation methods to validate their results.
