Presentation Transcript

  1. Video Analyses for Human-Computer Interaction How can users handle and appreciate the inherent complexity in interactive multimedia and what type of design elements can work as means to handle it? • control • activity and engagement • media vs. tool • temporal issues How do they react on design and what kind of use approach did they apply to handle the complexity Interaction approach and user experience as input to design • Calls for real life studies on a micro level The general goal is to arrive at principles for multimedia interaction design

  2. Material Observations Video: 2-3 schools every field trial approx. 80 hours, not equally distributed Field notes - my own, master students' other researchers' Products / Writings Presentations The software Plans for the field trials General project documents Interview Interview with one group Questionares (2nd trial) General interference during students project work

  3. Experience of the presentation in context: The user: "He is in there too long [on the canvas]" Then she closes the box for timing and moves up to play the scene through from the beginning. When the picture of the man disappears according to the new timing the user says: "But .. he ... he has to be there for a long time ... he has to be there the whole time [the whole scene]" The co-user: "Yes" ...and play through the scene another time. Timing elements as a numerical operation: She then selects the picture and opens the box for timing, and see the current timing: "He has to be ... Begins at 0 and ends at 20 [seconds]. What about 10?" The co-user: "Yes ... 10 or less" The user: "7, then" Changes the duration to 7 seconds. She then go back and change the numbering again Analyses of a sequence

  6. Video analyses: Practical • Prepare for the video footage • What do you want to get? • Prepare technically (Sound!) Ideally, have a small technical test • Consider how intrusive you are • Make a log of the material (as general as possible) • Select key sequences • Make categories (also by use of theory) • Make tentative statements continously • Study and comment material together

  7. Video Analyses: Some warnings • Easier to collect than to analyse • 'Sequence time' vs. 'analyses time' between 1:5 and 1:100, or more (!) • An extensive material tends to be contradictory • Considerable 'expressive challenges' • Categorisation, comparison, transcription

  8. Video analyses: What's good • A firm ground to base reserach on Compare to interview data: "What we call our data are really our own constructions of other people's constructions of what they and their compatriots are up to" Geertz(1973): Local Knowledge: Further essays in interpretative anthropology. Basic Books New York • A sourch of data to return to, with minimal ’interpretative layer’ • New interpretations of existing material Recommended: Sanderson and Fisher: "Exploratory Sequential Data Analyses" Human-Computer Interaction. 1994 Vol 9.
