摘要
在虚拟现实和遥操作系统中,力/触觉接口是非常重要的人机交互设备。目前的力觉装置有外骨骼和固定设备、数据手套和穿戴设备、点交互设备和专用设备等,这些力觉装置中采用气动、液压、电机或磁场等驱动的主动式力反馈居多,也有基于液体智能材料的被动式力觉反馈。触觉的实现方法主要有由电磁(螺线管、发声线圈)驱动的机械振动,压电晶体、形状记忆合金驱动的探针阵列,气动系统,热力泵(塞贝克效应)系统等。
Haptic interfaces are of importance in virtual reality and telepresece system. Most current force feedback dev＇ices, such as exoskeletons and stationary devices, gloves and wearable devices, pointsources and specific task devices and so on, are active devices actuated by a pneumatic system,hydraulic system, motors or magnetic field. Some of these devices are based on ERFs/MRFs. From the technological point of view, the tactile stimulation can be done by solutions based on mechanical needles actuated by electromagnetic techniques （ solenoids, voice coils）, piezoelectric crystals, shape memory alloys, pneumatic systems and heat pump systems based on Peltier modules.
