Abstract

Recent hand-held controllers have explored a variety of haptic feedback sensations for users in virtual reality by producing both kinesthetic and cutaneous feedback from virtual objects. These controllers are grounded to the user's hand and can only manipulate objects through arm and wrist motions, not using the dexterity of their fingers as they would in real life. In this paper, we present TORC, a rigid haptic controller that renders virtual object characteristics and behaviors such as texture and compliance. Users hold and squeeze TORC using their thumb and two fingers and interact with virtual objects by sliding their thumb on TORC's trackpad. During the interaction, vibrotactile motors produce sensations to each finger that represent the haptic feel of squeezing, shearing or turning an object. Our evaluation showed that using TORC, participants could manipulate virtual objects more precisely (e.g., position and rotate objects in 3D) than when using a conventional VR controller.
TORC:一种用于手持式高灵巧手指交互的虚拟现实控制器
最近的手持控制器通过产生来自虚拟物体的动觉和皮肤反馈,为用户在虚拟现实中探索了各种触觉反馈感觉。这些控制器与用户的手相连,只能通过手臂和手腕的运动来操纵物体,而不能像在现实生活中那样使用灵巧的手指。在本文中,我们提出了一种刚性触觉控制器TORC,它可以呈现虚拟物体的特征和行为,如纹理和顺应性。用户可以用拇指和两个手指按住TORC,并通过在TORC的触控板上滑动拇指来与虚拟物体进行交互。在交互过程中,振动触觉马达对每根手指产生感觉,代表挤压、剪切或转动物体的触觉。我们的评估表明,与使用传统的VR控制器相比,使用TORC,参与者可以更精确地操纵虚拟物体(例如,在3D中定位和旋转物体)。
