The goal is to propose an e-learning system to help the autonomy of the child with a personalized course. We have designed IntuiGeo , an Intelligent Tutoring System which allows the child to draw freely geometric figures by simulating the traditional pen and paper approach.\u00a0 IntuiGeo interprets, on the fly, the child\u2019s sketches, allowing for a real-time user interaction, and visual, corrective or guidance feedback interventions, in order to enhance the child\u2019s learning performance.<\/span><\/p>\n<p><a href=\"https:\/\/www-intuidoc.irisa.fr\/files\/2018\/05\/IntuiGeoErgo.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-1595\" src=\"https:\/\/www-intuidoc.irisa.fr\/files\/2018\/05\/IntuiGeoErgo-300x201.jpg\" alt=\"\" width=\"713\" height=\"478\" srcset=\"https:\/\/www-intuidoc.irisa.fr\/files\/2018\/05\/IntuiGeoErgo-300x201.jpg 300w, https:\/\/www-intuidoc.irisa.fr\/files\/2018\/05\/IntuiGeoErgo-768x515.jpg 768w, https:\/\/www-intuidoc.irisa.fr\/files\/2018\/05\/IntuiGeoErgo-1024x686.jpg 1024w\" sizes=\"auto, (max-width: 713px) 100vw, 713px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<p><span data-contrast=\"auto\">The interaction mode is stylus-fingers.

Volunteers professors from middle-schools in the region of Brittany allowed us to carry user experiments with their pupils in their classrooms. The experiments compared the pupils performance when using IntuiGeo with a control group using pen and paper. The results showed the positive impact of our tutor as well as the learning transferability between the supports since the pupils who used our tutor were also able to succeed better than the control group when they switched to the pen and paper support for the post-test experiment.<\/span><\/p>\n<p><b>Contact <\/b><br \/>\n\u00c9ric Anquetil (eric.anquetil@irisa.fr)<br \/>\nFull professor at INSA Rennes, IRISA laboratory<br \/>\nHead of\u00a0 <a href=\"http:\/\/www.irisa.fr\/intuidoc\">IntuiDoc team<\/a><\/p>\n<p><b>Researchers and engineers in the IntuiDoc team, involved in the ACTIF project<br \/>\n<\/b><\/p>\n<ul>\n<li>\u00c9ric Anquetil (Professor)<\/li>\n<li>Nathalie Girard\u00a0 (Associate Professor)<\/li>\n<li>Omar Krichen (PhD student)<\/li>\n<li>Simon Corbill\u00e9 (Research Engineer)<\/li>\n<li>Micka\u00ebl Renault (Research Engineer)<\/li>\n<li>Morgane Carry (Research Engineer)<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><b>Publications:<\/b><\/p>\n<ul>\n<li data-aria-posinset=\"1\" data-aria-level=\"2\"><a href=\"https:\/\/hal.archives-ouvertes.fr\/hal-01816617\"><span data-contrast=\"auto\">O.
