SoS, Signal Orchestration System

SoS, Signal Orchestration System
Wearable devices and classroom furniture to display digital signals indicating collaborative orchestration mechanisms

The Signal Orchestration System (SOS) augments the physical environment with digital signals indicating orchestration aspects. It includes a manager, where orchestration visual and auditory signals are configured, changed on the fly and transmitted. These signals are rendered in physical devices that students can easily wear in a way that the signals can be collectively perceived (by the rest of the students in a group). This facilitates awareness of the social dynamic and the activity flow. For instance, to indicate group formation, students’ devices can show color signals. The students with the same color form a group. Blinking lights can indicate role or resource distribution, sound signals change of activity, etc. However, the actual meaning of each signal depends on the needs and creativity of the teacher who design the collaborative dynamic and its orchestration.
