Telemaque, a new visuo-haptic interface for remediation of dysgraphic children

Abstract

The aim of this paper is to present a new visuo-haptic interface for remediation of dysgraphic children. This interface allows teaching the children to reproduce a letter according to a standard not only static (i.e. its correct shape) but also dynamic (i.e. the rules of motor production). A new specific handwriting static and dynamic font was built. Using this font, four exercises were carried out for each letter. First, the sculpturing of a letter was designed to familiarize the child with the haptic pen and the static and the global shape of a letter. Second, the circuit game was focused on the correct order of production of a letter. Third, the dynamical tracing exercise was dedicated to dynamical aspect of production of a letter. Fourth, the blindfolded recognition exercise of letters was focused on the static and dynamical aspects of a letter. This exercise required retrieving the letter in memory from dynamical haptic cues. The effects of these exercises on a dysgraphic child were currently assessed.
