  2. 2. 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)
  3. 3. 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)
  4. 4. 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 !
  5. 5. 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)
