Abstract
The spatial and motor skills used for handwriting are particularly difficult for visually impaired people to develop. These skills are required in order to sign an aesthetically pleasing and repeatable signature, which is often required for documents such as legal agreements and job applications. In a previous study, a system called McSig 1.0 was designed to teach visually impaired students how to write letters and eventually, a signature. McSig 1.0 is designed for the teacher and student to work together. The system recreates the movement of the teacher’s pen for the student. The student holds a pen which is attached to the mechanical arm on a PHANTOM Omni haptic device. The teacher scribes a letter shape on a Tablet PC screen. As the teacher’s pen moves, software causes the mechanical arm to move the student’s pen around the trajectory of the stroke, so that the student’s hand is guided through the formation of the letter. At the same time, the stereo pan and pitch of a sound tone are altered to express the movement of the pen in the x and y axes, respectively. The tip of the student’s pen moves over a tactile plastic sheet. The sheet is scored, leaving a tactile ridge that the
