论文摘要
天然运动界面对于许多VR应用的开发至关重要。对于家庭VR应用，有两个基本要求：自然的沉浸式经验和最小化的空间职业。现有的运动策略通常不能同时满足这两个要求。本文提出了一种新型的全向跑步机（ODT）系统，称为Hex-Core-Mk1（HCMK1）。通过实施两种镜像对称的螺旋滚筒来产生全向速度场，该提议的系统能够在小至1.76 m^2的区域中提供真正的自由度的真实步行体验，同时在重量，音量，量，潜伏期和动态性能方面，在几个现有的ODT系统上提供了很大的优势。与InfineDeck和HCP的尺寸相比，到目前为止，两个最佳电动机驱动的ODT是HCMK1的8 cm高度仅占InfineDeck的20％，而HCP的50％的高度为50％。此外，HCMK1是一种仅重110公斤的轻质设备，它提供了进一步扩展VR场景的可能性，例如地形模拟。 HCMK1的延迟仅为23ms。实验表明，HCMK1可以以16.00 m/s^2的起始加速和30.00 m/s^2的制动加速度传递。
The natural locomotion interface is critical to the development of many VR applications. For household VR applications, there are two basic requirements: natural immersive experience and minimized space occupation. The existing locomotion strategies generally do not simultaneously satisfy these two requirements well. This paper presents a novel omnidirectional treadmill (ODT) system, named Hex-Core-MK1 (HCMK1). By implementing two kinds of mirror symmetrical spiral rollers to generate the omnidirectional velocity field, this proposed system is capable of providing real walking experiences with a full-degree of freedom in an area as small as 1.76 m^2, while delivering great advantages over several existing ODT systems in terms of weight, volume, latency and dynamic performance. Compared with the sizes of Infinadeck and HCP, the two best motor-driven ODTs so far, the 8 cm height of HCMK1 is only 20% of Infinadeck and 50% of HCP. In addition, HCMK1 is a lightweight device weighing only 110 kg, which provides possibilities of further expanding VR scenarios, such as terrain simulation. The latency of HCMK1 is only 23ms. The experiments show that HCMK1 can deliver on a starting acceleration of 16.00 m/s^2 and a braking acceleration of 30.00 m/s^2.
