触觉反馈是虚拟现实交互中一种重要的感知方式。触觉意味着力反馈（模拟物体硬度、重量和惯性）和触觉反馈（模拟表面接触几何形状、光滑度、滑动和温度）。提供这样的感觉数据需要桌面或便携式专用硬件称为触觉接口。物理交互建模涉及精确的碰撞检测、实时力计算和高控制回路带宽。这导致需要在联网计算机上进行多处理器并行处理的大计算负荷。触觉密集型VR模拟的应用包括CAD模型设计和装配。改进的技术（可穿戴计算机，新型执行器，触觉工具包）将在未来的VR模拟中增加力/触觉反馈的使用。
Haptic feedback is a crucial sensorial modality in virtual reality interactions. Haptics means both force feedback (simulating object hardness, weight, and inertia) and tactile feedback (simulating surface contact geometry, smoothness, slippage, and temperature). Providing such sensorial data requires desk-top or portable special-purpose hardware called haptic interfaces. Modeling physical interactions involves precise collision detection, real-time force computation, and high control-loop bandwidth. This results in a large computation load which requires multi-processor parallel processing on networked computers. Applications for haptics-intensive VR simulations include CAD model design and assembly. Improved technology (wearable computers, novel actuators, haptic toolkits) will increase the use of force/tactile feedback in future VR simulations.
