Virtual Reality Haptic Device Design

摘要: 随着5G技术的发展和计算机技术的快速进步，虚拟现实(VR)技术的应用范围日益扩大。新冠疫情和人际互动的需求进一步推动了VR技术的增长。在此背景下，VR设备的设计和开发变得尤为重要。在数字化和网络化的推动下，人类对虚拟世界的探索从未停歇，追求更真实的虚拟体验。当前的VR产品仅依赖听觉和视觉已无法满足沉浸式交互的需求，技术发展正向触觉感官扩展。与国际相比，中国的VR触觉反馈技术起步较晚，但市场潜力巨大，增长迅速。然而，市面上的触觉手套多处于原型测试阶段，存在外观设计不足、触觉反馈弱和沉浸感不强等问题。本文设计了一款新型触觉手套，包含手套主体、控制系统、传感追踪系统和微型震动反馈模块。手套主体采用硅橡胶材质，内部嵌入柔性传感器，可追踪手部动作并将其映射到虚拟场景。控制器收集传感器数据并转化为触觉反馈信号，使用户感受到虚拟物体的重量、形状和大小。该设计强调了传感器的低延迟和高精度、触觉反馈的真实性、沉浸式体验以及与其他VR设备的适配性。一个主要创新点是传感器和控制器可拆卸，允许用户在普通手套、数据手套和VR手套之间切换，并实现组件在不同型号手套上的替换使用。本研究对提升虚拟现实世界的感知深度和交互质量具有显著意义。

Abstract: With the development of 5G technology and rapid advancements in computer technology, the application scope of Virtual Reality (VR) technology is expanding day by day. The COVID-19 pandemic and the need for interpersonal interaction have further propelled the growth of VR technology. Against this backdrop, the design and development of VR devices have become particularly crucial. Driven by digitalization and networking, humanity’s exploration of the virtual world has never ceased, in pursuit of more realistic virtual experiences. Current VR products that rely solely on auditory and visual senses can no longer meet the demands of immersive interaction; technological development is expanding towards tactile senses. Compared to the international arena, China’s VR haptic feedback technology started relatively late, but the market potential is enormous and the growth is rapid. However, many haptic gloves on the market are still in the prototype testing phase, with issues such as insufficient exterior design, weak haptic feedback, and a lack of immersion. This paper designs a new type of haptic glove, which includes a glove body, control system, sensing tracking system, and micro-vibration feedback module. The glove body is made of silicone rubber, with flexible sensors embedded inside to track hand movements and map them to virtual scenarios. The controller collects sensor data and converts it into haptic feedback signals, allowing users to feel the weight, shape, and size of virtual objects. The design emphasizes the low latency and high precision of the sensors, the authenticity of haptic feedback, immersive experience, and compatibility with other VR devices. A major innovation is that the sensors and controllers are detachable, enabling users to switch between ordinary gloves, data gloves, and VR gloves, and to replace components on different models of gloves. This research has significant implications for enhancing the depth of perception and quality of interaction in the virtual reality world.
