EXPECTED INFORMATION NEEDS OF PARENTS FOR PERVASIVE AWARENESS SYSTEMS Vassilis-Javed Khan, Panos Markopoulos, Boris de Ruyter, Wijnand IJsselsteijn
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.
AWARENESS SYSTEMS FOR COUPLES Strong & Gaver Tollmar & Joakim Vetere et.al.
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: 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.
