Abstract

Personal vehicles such as the Segway have been actively used for security patrols or supervision of construction sites, because of their mobility capabilities. In the current study, we proposed a vehicle-ride sensation sharing system enabling a rider to remotely collaborate with a driver, and to receive both 3D visual perception and vibro-vestibular sensation. We developed a prototype personal vehicle system with two 360° cameras attached to the Segway with a stabilizer to capture stereoscopic 3D images and send them to each eye of a head-mounted display worn by a remotely collaborating rider. We also developed a prototype of vibro-vestibular display by modifying a conventional wheelchair with a simple lightweight mechanism for actuation and vibration by two DC motors. In our presentation algorithm, each wheel of the wheelchair is accelerated or decelerated proportionally to the acceleration of each wheel of the Segway. When the velocity of each wheel was almost constant and the acceleration was nearly zero, the wheelchair slowly moved to the initial position, with movement that the rider could not perceive, to keep the wheelchair accelerating or decelerating in a limited space.
TwinCam Go:基于立体3D视觉感知和振动前庭反馈的沉浸式远程协作的车辆驾驶感觉共享方案
赛格威(Segway)等个人车辆由于其机动性,已被积极用于安全巡逻或建筑工地监督。在当前的研究中,我们提出了一种车辆乘坐感觉共享系统,使乘客能够与驾驶员远程协作,并同时接收3D视觉感知和振动前庭感觉。我们开发了一个原型个人车辆系统,将两个360°摄像机连接到带有稳定器的赛格威上,以捕获立体3D图像,并将它们发送到远程协作骑手佩戴的头戴式显示器的每只眼睛。我们还开发了一个振动前庭显示的原型,通过修改传统轮椅与一个简单的轻量级机构驱动和振动的两个直流电动机。在我们的演示算法中,轮椅的每个轮子与赛格威的每个轮子的加速度成比例地加速或减速。当每个车轮的速度几乎恒定,加速度几乎为零时,轮椅缓慢地移动到初始位置,这种移动是骑乘者无法感知的,以使轮椅在有限的空间内保持加速或减速。
