PROJECT TITLE :

Electrotactile Augmentation for Carving Guidance

ABSTRACT:

In this study, we tend to presented an economical and unobtrusive tactile feedback system, which is used to train dental technicians in carving tasks employing a wax stick and knife. First, we tend to developed a technique for generating performance metrics employing a model-based estimation of clearance angles between an object's surface and also the carving blade. The calculated clearance angles are compared with desired angles obtained from knowledgeable operators. Then, angular errors are presented as tactile cues to the user's finger pads through electrical stimuli at the center phalanx of the index finger and the thumb. Subsequently, we tend to conducted a feasibility test with novice dental technicians, who showed improvement in initial clearance angles of carving strokes. Moreover, the results showed important reduction in the prevalence rate of poor-carving when using the proposed system. From these results, we tend to concluded that electrotactile augmentation will provide effective steerage for carving tasks.
