Assisting hand skill transfer of tracheal intubation using outer-covering haptic display

Abstract

Various systems for hand tool skill training have been developed in the domain of haptic displays. These systems typically present force to a learner's palm by directly actuating the tool. However, this approach is sometimes ineffective because learners have difficulty sensing the haptic feedback from the tool when they are holding it tightly. Thus, we propose a different approach (OCHD) that effectively guides the learner's hand by presenting force to the back of his/her hand as if an instructor is holding it. A preliminary experiment showed that OCHD effectively guides users with less actuator drive force than cases where the tool is directly actuated.

Haptics to improve task performance in people with disabilities: A review of previous studies and a guide to future research with children with disabilities

“…In medical applications, for instance, guidance is used for palpatory training by following the recorded position trajectories of an expert physician, 108 or training practitioners to learn how much force to apply during a surgical procedure. 109 In wheelchair driving training, the trainee learns motor training strategies through guidance from an experienced person (physical guidance) or forces generated by software (virtual guidance), 53,106 or it allows training novice users or children with disabilities on how to use the wheelchair controls. 106 Guidance has also been used to replicate an expert's motor skills in order to facilitate hand movements for training handwriting (e.g.…”
