论文摘要
近年来，虚拟现实（VR）头部安装式显示器（HMD）已用于实时提供身临其境的，第一人称的视野，用于无人驾驶的遥控地面车辆（UGV）。一个关键的问题是，要感知车辆周围障碍物与HMD中2D视图的距离，这是一项挑战，从而恶化了UGV的控制。 HMD中使用的常规距离指标占用了屏幕空间，该屏幕空间会导致显示屏上的混乱，并可以进一步降低对物理环境的意识。为了解决这个问题，在本文中，我们建议使用Vibro-Tactile和/或轻视觉提示在屏幕外反馈，以为UGV遥控器提供实时距离信息。一项研究的结果表明，在反馈类型，减少工作量以及提高驾驶任务中的可用性方面的性能明显更好，这需要持续了解UGV及其环境对象或障碍之间的距离。我们的发现表明了一个可靠的案例，可用于在高度依赖对象距离感知的UGV的远程操作中，以支持设备内的泡沫触觉和/或光视觉反馈。
In recent years, Virtual Reality (VR) Head-Mounted Displays (HMD) have been used to provide an immersive, first-person view in real-time for the remote-control of Unmanned Ground Vehicles (UGV). One critical issue is that it is challenging to perceive the distance of obstacles surrounding the vehicle from 2D views in the HMD, which deteriorates the control of UGV. Conventional distance indicators used in HMD take up screen space which leads clutter on the display and can further reduce situation awareness of the physical environment. To address the issue, in this paper we propose off-screen in-device feedback using vibro-tactile and/or light-visual cues to provide real-time distance information for the remote control of UGV. Results from a study show a significantly better performance with either feedback type, reduced workload and improved usability in a driving task that requires continuous perception of the distance between the UGV and its environmental objects or obstacles. Our findings show a solid case for in-device vibro-tactile and/or light-visual feedback to support remote operation of UGVs that highly relies on distance perception of objects.
