Abstract

Virtual reality has already been successfully used as a therapeutic tool for the treatment of various phobias. Due to advances in the 3D graphics and in the computing power, the real-time visual rendering of a virtual world poses no significant problems nowadays. However, the haptic interaction with such environments remains a challenge. This paper explores the haptic interaction with a dedicated virtual environment in spider phobia treatment to elicit disgust, as changes in fear and in disgust were shown to be highly associated with the observed decline in arachnophobic symptoms. A dedicated virtual environment is programmed within which a Novint Falcon haptic device is used for the interaction with a virtual spider. Different software options for interfacing with the haptic device and for the modeling of 3D objects are compared and discussed. Three testing scenarios are implemented that allow a subject to be gradually exposed to his/her spider phobia.

在恐惧症治疗中，与虚拟蜘蛛互动引起厌恶

虚拟现实已经被成功地用作治疗各种恐惧症的治疗工具。由于三维图形和计算能力的进步，虚拟世界的实时视觉渲染已经不是什么大问题了。然而，与这种环境的触觉交互仍然是一个挑战。本文探讨了在蜘蛛恐惧症治疗中与专用虚拟环境的触觉相互作用，以引起厌恶，因为恐惧和厌恶的变化被证明与观察到的蜘蛛恐惧症症状的下降高度相关。一个专用的虚拟环境被编程，在其中使用Novint Falcon触觉设备与虚拟蜘蛛进行交互。比较和讨论了用于与触觉设备接口和用于3D对象建模的不同软件选项。实施了三个测试场景，允许受试者逐渐暴露于他/她的蜘蛛恐惧症。
