Abstract: A learning and training process that memorizes traces of a learner solving an exercise, attaches meta labels to the learner traces, and compares the learner traces to reference traces of a referent solving the exercise, meta labels being attached to the reference traces.

Abstract: A process and device for simulating a product printed by a virtual press. The process implemented by the device includes creation of a three-dimensional object page, selection of at least one fold among a set of predetermined folds, with the selected folds corresponding to the folds produced on the product to be simulated, for each fold produced and selected, a modification of the three-dimensional object page by the addition of at least one fold line at a given position on the three-dimensional object page, construction of the simulated product starting from the modified three-dimensional object page, and a display of the simulated product constructed in this manner.
