A bidirectional haptic device for the training and assessment of handwriting capabilities

Haptic devices have been used to help people to learn or recover specific movements. An interesting application is the handwriting. In this paper we present a haptic device designed to help people to improve their writing skills. Guided by a teacher, who controls one of the mechanisms providing the haptic feedback, a group of students were asked to write few words using their second hand. The test led to some interesting outcomes. A quantitative analysis is then carried out in order to support the considerations uniquely based on the qualitative observation of the results.
