Santos-Gago1, Manuel Caeiro-Rodríguez1, Manuel J. Fernández Iglesias1 1Department of Telematics Engineering, University of Vigo, Campus Lagoas-Marcosende A protocol to evaluate solutions based on commercial-off-the-shelf (COTS) wrist wearables to estimate stress in students is proposed. The protocol is carried out in two phases, an initial laboratory-based stress induction test, and a monitoring stage taking place in the classroom while the student is performing academic activities.
