近年来，不受地面和人体约束的非接地触觉显示器已被深入研究。为视力受损者提供路线导航和紧急情况下的逃生被认为是此类设备的应用，因为该设备应在空间中是自由的。然而，由于用户受到的反作用力应该在其他地方得到支持，因此难以显示除了伪力之外的实际力。鼓风机是一种可能的解决方案，可以在半空中显示实际的力量，因为空气与风压反应，而无需接地。在这里，我们提出了一种使用风压的非接地触觉显示器。显示器改变力方向，因为器械应产生平移和旋转力以向前导航并改变方向。器械还应显示与器械姿势无关的力。所设计的设备有两个风扇，每个风扇安装在手柄末端的双轴万向节上。该设备可以通过将两个风扇分别定向到相同和相反的方向来显示平移力和旋转力。我们开发了一个原型设备，并进行了人体受试者的研究，以调查该设备的性能方面的方向歧视和完成时间与不同的方向和力模式。结果表明，平移和旋转力都可以显示，旋转力的感知更清晰。© 2016日本电气工程师协会。由John Wiley & Sons公司出版
In recent years, a non‐grounded haptic display that is unconstrained from the ground and the human body has been studied intensively. Route navigation for the visually impaired and escape during an emergency have been considered as applications of such devices because the device should be free in space. However, it is difficult to display the actual force other than a pseudo force because the reaction force received by a user should be supported elsewhere. A wind blower is a possible solution that can display the actual force in midair because the air reacts with the wind pressure without grounding. Here, we propose a non‐grounded haptic display that uses wind pressure. The display changes the force directions because the device should generate translational and rotational forces to navigate forward and change directions. The device should also display the force independent of the device posture. The designed device has two fans, each of which is mounted on two‐axis gimbals at the end of the grip. The device can display translational and rotational forces by orienting the two fans to the same and opposite directions, respectively. We developed a prototype device and conducted a human subject study to investigate the performance of the device in terms of direction discrimination and completion time with different directions and force patterns. The results showed that both translational and rotational forces could be displayed and that rotational forces were perceived more clearly. © 2016 Institute of Electrical Engineers of Japan.
