Abstract

In this paper we propose an Outer-Covering Haptic Display (OCHD) method to better teach learners how much force to apply to the tool during a laryngoscopy. Laryngoscopy is a medical procedure in which a tool called a laryngoscope is used to open a patient's mouth to view the vocal folds and glottis. The OCHD imparts haptic sensation to the back of the hand holding the laryngoscope, and guides the learner to perform the procedure. The learner moves the laryngoscope by his/her own force and receives the tool application force sensation on the palm of the hand. To evaluate the OCHD method, we conducted the comparison experiments with two existing methods, the haptic guidance method that directly actuates the tool, and the visual information guidance method. The results showed that, the OCHD method is more effective than existing methods for hand skill training which require learner to apply strong force to his/her palm such as in laryngoscopy.
