GTI                                                                         http://gti.upf.edu



                               Motivation
•  Dynamic collaborative activities in physical spaces
   (classroom) -> “knowledge-intensive” social interactions
   -> learning
•  The orchestration “overhead” hinders its adoption:
      •  Indicate group formation and role assignment for every activity,
        distribution of resources/tools, collaboration areas, …
        considering the evolution of the learning situation/constraints

      •  Teachers and students devote attention to orchestration aspects

      •  Time-consuming, noise / mess effect (disorganization/distraction)

      •  +demanding when +students


(Connection to virtual spaces… see Hernández-Leo et al., to be published)
GTI                                                         http://gti.upf.edu



                            Our statement
  •  Augmenting physical educational spaces with
      “orchestration awareness mechanisms” can facilitate
      the orchestration of collaborative dynamics


       •  Our solution:

          Wearable and fixed devices
          that “communicate”
          orchestration aspects (signals)


  •  Related work
      e.g., ambient displays to support
      classroom activity supervision using
      interactive lamps (Alavi & Dillenbourg, in press)
GTI                                                                http://gti.upf.edu



                Signal Orchestration System
•  Visual and auditory signals (color, blinking, sound,…)
•  From manager to wearable devices
   Signals collectively perceived
•  Examples:
        •    Colors: group formation, work areas
        •    Blinking: role distribution
        •    Sound: change of activity
        •    (Depends on teachers’ creativity and needs)



•  Vs. smart phones
      •  Sometimes not available / not allowed / cost
      •  Attention distraction / cognitive load / -agile dynamic
      •  “Ambient group awareness effect” difficult to achieve !
GTI                                                             http://gti.upf.edu



      Wearable devices: designs / experiments
                -  Necklace:  + visible,  considerable
                  size / weight, uncomfortable




                -  Fabric:  Lighter and thinner,
                  aesthetically nicer;
                   - visible: since + comfortable  risk of
                  forgetting to check, too similar to clothes
                  of classmates



                -  Arm bracelet: intermediate approach,
                  compact, more robust,
                  awareness also when sitting down…
                  (vs. control group:
                  -time
                  + group awareness, enjoyment, performance)

                                         (Hernández-Leo et al., EC-TEL 2011;
                                  Hernández-Leo et al., JUCS to be published)
