在半空中显示虚拟物体的能力，可以看到没有特殊的头盔是一个有吸引力的主张，为不久的将来的虚拟现实系统。体积显示技术已经证明了这一概念，允许用户在3D空间中查看具有真实的尺寸的虚拟对象，同时实现某些形式的交互。已经见证了触觉反馈技术的发展，触觉反馈技术用于在数字世界中传递触觉。随着虚拟环境在当今世界中的应用越来越广泛，触觉反馈设备有可能与虚拟现实系统集成，并有助于提供更具沉浸感和交互性的用户体验。在此，提出了一种名为Aerohaptics的基于空气的触觉反馈设备，其在用户操纵伪全息显示器内的虚拟对象时传递半空中的触觉反馈。所开发的系统构成了一种具有成本效益的方法，具有相对较低的复杂性和各种潜在的应用，因为不需要可穿戴或手持外设。所传递的触觉反馈可以准确地指向用户手上的特定位置，并且可以控制其强度以适应各种交互场景。通过实验，局部反馈用户的指尖，以及根据用户的手的运动变化的反馈力被证明。
The ability to display virtual objects midair that can be seen without special headwear is an attractive proposition for the virtual reality systems of the near future. Volumetric display technologies have demonstrated this concept, allowing users to view virtual objects with real dimensions in 3D space while enabling some forms of interaction. Developments have been witnessed in haptic feedback technologies which are used to deliver a sensation of touch in the digital world. As virtual environments find more applications in today's world, haptic feedback devices have potential to integrate with virtual reality systems and contribute to a more immersive and interactive user experience. Herein, an air-based haptic feedback device, named Aerohaptics, is presented, which delivers mid-air tactile feedback while the user is manipulating virtual objects within a pseudo-holographic display. The developed system constitutes a cost-effective approach with relatively low complexity and various potential applications as no wearable or handheld peripherals are required. The delivered haptic feedback can be accurately directed at specific locations on the user's hand and its intensity can be controlled to suit various interaction scenarios. Through experiments, localized feedback on the user's fingertips as well as varying feedback force according to the user's hand movement is demonstrated.
