Résumé :
Due to a lack of appropriate tools, learning geometry remained difficult for a blind pupil...until a new kind of devices was released : haptic devices. Those kind of tools, plugged to a basic Personal Computer, allow people to feel and explore virtual objects using the sense of touch. Thus, the idea of the SALOME project is to use such a device to help blind pupils to learn geometry . Although a large part of the relevant issues had been tackled since 2003 (beginning of the software developments at France Telecom), a huge ergonomic issue appeared : so far, exploration was performed with the haptic device and construction with the keyboard. This way of interacting with SALOME proved quite boring for children and leaded to substantial waste of time.
This internship aims at integrating the possibility to use exclusively the haptic device to build geometrical elements (triangle, segment...). The solution chosen consists in using SYMBAL ( a 2-dimensional gesture recognizer developed at France Telecom Recherche and Development) to transform the haptic device into a gesture commands device (one command is executed when its associated gesture is recognized).
This work is divided into three different topics : 1) to make every geometrical constructions available by gesture commands ; 2) to develop and test a possible solution to make gestures learnable for blind people ; 3) to develop a protocol and some tools to carry out an experiment aimed at testing the usability of such a gesture command-based software.
