本文研究了基于触觉的交互对于在虚拟环境中执行装配相关任务的好处。该研究研究了触觉反馈影响用户表现的环境，并确定了受影响的装配操作。四十名参与者完成了三项与虚拟装配相关的实验：重量辨别、零件定位和手动装配。每个实验都包含一系列由性能变量的因子组合生成的试验。根据任务完成时间和不同的准确性衡量标准对受试者进行评估。与仅视觉方法相比，定量结果表明，基于触觉的交互有利于通过减少重量辨别的完成时间来提高性能，在定位虚拟对象时允许更高的放置精度，并能够沿着三维轨迹实现更稳定的手部运动。结果还表明，用户在重量辨别方面的准确性取决于结合所提供的感官信息操纵虚拟对象时的手部优势。
This paper investigates the benefits of haptics-based interaction for performing assembly-related tasks in a virtual environment. The research examines the context in which haptic feedback affects user performance and identifies assembly operations that are influenced. Forty participants completed three experiments relevant to virtual assembly: weight discrimination, part positioning, and manual assembly. Each experiment featured a series of trials generated from factorial combinations of performance variables. Subjects were assessed based on task completion time and different measures of accuracy. When compared to visual-only methods, quantitative results show that haptics-based interaction is beneficial in improving performance by reducing completion times for weight discrimination, permits higher placement accuracy when positioning virtual objects, and enables steadier hand motions along three-dimensional trajectories. The results also indicate that user accuracy in weight discrimination is dependent on hand dominance when manipulating the virtual object combined with the provided sensory information.
