Robot teacher can tell if students get distracted
Scientists
have developed a robot teacher that can detect whether children are distracted
in class and accordingly respond to encourage them to pay attention.
Luis
Imbernon Cuadrado and colleagues at the Department of Artificial Intelligence
in Madrid have developed the system for use, with software applications, in
schools.
“The
main goal of our work was to design a system that can detect the emotional
state of primary school children interacting with educational software and make
pedagogic interventions with a robot tutor that can ultimately improve the
learning experience,” said Mr. Cuadrado.
Rather
than focusing on specific emotions, the researchers first identified three
cognitive states (concentrating, distracted and inactive) known to influence
the course of learning.
Keyboard
strokes and mouse actions of children using educational software were used to
predict whether children were distracted or inactive.
An
algorithm then chooses pedagogic intervention to engage students.
These
could be words and gestures of encouragement or an attempt to spark interest in
a learning objective, all of which can be delivered by the robot tutor.
“The
next step will be to implement methods for detecting a more complex range of
emotions with cameras and microphones and to test the longer term impact of
robot tutors on children’s learning curves,” Mr. Cuadrado said. — PTI
