指端可穿戴式力触觉交互装置设计与评估

Design and evaluation of a wearable fingertip haptic interaction device

可穿戴式力触觉交互技术作为力触觉交互技术的一个分支,可以为操作者提供更为真实、自然的人机交互体验。设计了一种指端可穿戴式力触觉交互装置,装置由穿戴于腕部的控制盒以及穿戴于指尖的部分组成,穿戴于指尖的部分重约30g,尺寸为38mm×31mm×50mm。装置采用连杆机构,可实现三自由度的力触觉反馈。装置使用蓝牙通信,具有小型轻便、穿戴方便的特点。通过方向感知与识别实验证明,装置可在指腹面产生8个有效的方向性信息,而且每个方向都可以为人所正确感知。此外,虚拟环境交互实验证明,装置可帮助人在虚拟环境中控制交互力的大小,并提高人机交互的效率。

As a branch of haptic interaction technology, wearable haptic interaction technology can provide operators with a more realistic and natural human-computer interaction experience. In this work, a wearable fingertip haptic interaction device is designed. The device consists of a control box worn on the wrist and a structure worn at the fingertip, and the structure weighs only about 30g with a size of 38 mm×31 mm×50 mm. The device uses linkage mechanism and can realize 3 DOF haptic feedback. The device adopts bluetooth communication and is small, lightweight and easy to wear. The direction perception and recognition experiment indicate that the device can produce 8 effective directional information on the finger pad, and each direction can be correctly perceived by subjects. In addition, the virtual environment interaction experiment proves that the device can help people control the interaction force in the virtual environment and increase the efficiency of human-computer interaction.
