Providing accurate sensory information to the individual with a myoelectric limb is of great importance for improving device use in a wide variety of tasks. A number of feedback systems presently being investigated rely on either vibrotactile or electrotactile skin stimulation, which does not provide sensory patterns similar to those in a natural grasping hand. A prototype system was developed to enhance sensory information transfer by using a technique in which the feedback modality (pressure) was the same as the grasping pressure. The present study compared the developed system (pressure) with vibrotactile feedback, vision, and compounds of these three modes. It was found that the pressure-pressure concept reduced grasping pressure replication errors and error variability.
为使用肌电肢体的个体提供准确的感官信息对于改善其在各种任务中的设备使用非常重要。目前正在研究的一些反馈系统依赖于振动触觉或电触觉皮肤刺激，而这些刺激并不能提供与自然抓握手中类似的感官模式。通过使用一种反馈模式（压力）与抓握压力相同的技术，开发了一个原型系统以增强感官信息传递。本研究将开发的系统（压力）与振动触觉反馈、视觉以及这三种模式的组合进行了比较。结果发现，压力-压力概念减少了抓握压力复制误差和误差变异性。
