三维(3D)显示以其自然直观的方式受到广泛关注。提出一种基于悬浮真三维显示系统的指套式力触觉交互方法。通过Leap Motion提取指尖坐标,利用双目相机实现光场显示区域和交互区域的坐标转换;判断手与显示区域的位置关系,传递信号使指套振动,从而完成力触觉交互。结果表明,利用所提方法可以完成光场显示区域和交互区域的坐标转换,转换精度在5 mm以内。当用户与三维显示模型交互时,有效和实时的力触觉交互有助于增强真实的感官体验。

Three-dimensional (3D) display has gained wide attention for its natural and intuitive performance. Herein, we proposed a finger sleeve haptic interaction method based on a suspended 3D display system. The fingertip coordinates were extracted by Leap Motion and a binocular camera was used to assist the coordinate transformation between light field display area and interaction area. Then, the position relation between the hand and display area was examined and the signal was transmitted to vibrate the finger sleeve, thus the haptic interaction was finally realized. The results show that the proposed method can be used to complete the coordinate transformation between light field display area and interaction area with a transformation precision of within 5 mm. Furthermore, when the user interacts with a 3D display system, the effective and real-time haptic interaction enhances their real sensory experiences.
