The interactive environment developed will allow for instance the teacher to ask an open question to
all the learners by expecting a drawing, a symbol or a formula as answer that will be handwritten with
a stylus (electronic ink) on a tablet screen.
The objective is to analyse in real time all graphical responses of learners to make a synthesis explicable
by the teacher: aggregation, interpretation or automatized clustering of graphical responses.
The challenge consists in having a generic approach allowing different nature of graphical responses
(e.g. formula, writing, symbols …) to be apprehended for:
 Combining graphical responses of children in an intelligible way (saliency map, interactive
graphics clouds) ;
 Elaborate different visualisation levels from the emergence of “cluster” of solution ;
 Make the summary map interactive to allow an intuitive and progressive reading of the
elements of responses based notably on the identified clusters.
