摘要

在本研究中,我们对一个系统进行了原型设计和测试,该系统允许用户在不佩戴任何设备的情况下用多个手指操作3D虚拟对象。自动立体显示器产生3D图像,深度传感器测量手指的运动。当用户触摸虚拟物体时,触觉反馈由超声波相控阵提供。通过估计与虚拟物体接触的手指的横截面,并通过在其周围创建一个力模式,用户可以识别相对于手指的表面位置。为了评估我们的系统,我们进行了两个实验,以表明所提出的反馈方法在识别物体表面方面是有效的,从而使用户能够在看不到物体的情况下快速抓住物体。

Direct Finger Manipulation of 3D Object Image with Ultrasound Haptic Feedback
In this study, we prototype and examine a system that allows a user to manipulate a 3D virtual object with multiple fingers without wearing any device. An autostereoscopic display produces a 3D image and a depth sensor measures the movement of the fingers. When a user touches a virtual object, haptic feedback is provided by ultrasound phased arrays. By estimating the cross section of the finger in contact with the virtual object and by creating a force pattern around it, it is possible for the user to recognize the position of the surface relative to the finger. To evaluate our system, we conducted two experiments to show that the proposed feedback method is effective in recognizing the object surface and thereby enables the user to grasp the object quickly without seeing it.
