4. Applications

These results open up a wide range of possible applications for this type of visuo-haptic simulator, particularly in learning foreign alphabets (Indian, Japanese, Chinese, Greek, etc.). Writing simulators can also be offered to children, taking into account their specific cognitive abilities. Indeed, Palluel et al. have shown, in 6-year-old children, similar results to those presented above with position-based haptic guidance, whereas this type of guidance seems less suitable for adults. This difference must be weighed against the lack of certainty regarding the mechanisms by which motor information is stored in writing, and should be taken into account when designing such devices.

Other applications are conceivable, such as the re-education of dysgraphia or the relearning of handwriting in the case of amputations. However, we must be cautious...
