A little girl lines up plastic letters in front of a little robot. The robot struggles to reproduce them on a tablet. The girl kindly steps in to help, writing out the word to show the robot how to do it. She puts in effort to teach the robot, without realizing that she is actually the one who is improving her writing skills. Yesterday, EPFL researchers introduced their new teaching tool at the Conference on Human-Robot Interaction (HRI) held in Portland, the USA.
The program is based on a principle called “Learning by Teaching”. When children experience difficulties in writing, they can easily lose confidence, or even gradually lose interest in the learning process. Eventually, their entire education can be affected. When students put themselves in the place of a teacher and pass on what they know to their peers, they can regain their self-confidence and interest in their studies.
Scientists developed progressive writing algorithms (算法) and used them in an existing robot model which was designed to interact with humans. With these algorithms, the machine can slowly draw words on demand, and then gradually improve. To do this, it uses many handwriting examples, which allow it to reproduce common errors made by young children while learning. It
is also possible to program the robot so that it can pay attention to the particular difficulties of a student.
The system has already been used in primary school lessons with about seventy students ranging from six to eight years old, and then individually with a six-year-old child for one hour per week over the course of one month. So far the system has been very well received.
