EXPECTED INFORMATION NEEDS OF PARENTS FOR PERVASIVE AWARENESS SYSTEMS 08.11.07 Vassilis-Javed Khan, Panos Markopoulos, Boris de Ruyter, Wijnand IJsselsteijn Slide 2 INDEX PhD background info, Definition of Awareness Systems (AS), Examples of AS, Motivation & Study Method, Results & Conclusions. Slide 3 OVERALL GOAL How can Awareness Systems support intra-family communication? Slide 4 MY FOCUS Communication between busy parents Couples: Both working, Have at least one dependent child, Goal is to support their communication with Awareness Systems Slide 5 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. Slide 6 AWARENESS SYSTEMS FOR COUPLES Strong & Gaver Tollmar & Joakim Vetere et.al. Slide 7 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? Slide 8 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. Slide 9 METHOD Through literature review of papers describing AS & our interview transcripts we formed 41 statements representing Awareness Information that can be exchanged. Slide 10 METHOD: EXAMPLE OF STATEMENT Slide 11 Slide 12 Slide 13 Slide 14 METHOD: ASKING IN 2 STEPS Slide 15 METHOD: ASKING IN 1 STEP Slide 16 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. Slide 17 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. Slide 18 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. Slide 19 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. Slide 20 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. Slide 21 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.
