多种感觉方式收集有关我们周围环境的信息，以根据环境及其内物体的属性计划适当的运动。这项研究旨在检查视觉和触觉信息单独和一起检测曲率的灵敏度。当视觉和触觉信息都存在时，信号发生的时间延迟被用来确定视觉上的触觉估计曲率的干扰的异步感觉信息的效果。即使在视觉和触觉信息明显不同的最大时间延迟下，视觉信息的呈现也会影响曲率的触觉感知。与单峰视觉条件相关联的不确定性小于在单峰触觉条件下，无论是主动采购的触觉信息，或在机器人辅助曲率检测。当视觉和触觉信息都可用时，不确定性没有减少;它等于单峰触觉条件。视觉和触觉信息的权重是高度可变的科目，一些科目作出判断，主要是基于触觉信息，而其他人往往依赖于视觉信息相等或更大程度上比触觉信息。
Multiple sensory modalities gather information about our surroundings to plan appropriate movements based on the properties of the environment and the objects within it. This study was designed to examine the sensitivity of visual and haptic information alone and together for detecting curvature. When both visual and haptic information were present, temporal delays in signal onset were used to determine the effect of asynchronous sensory information on the interference of vision on the haptic estimate of curvature. Even under the largest temporal delays where visual and haptic information were clearly disparate, the presentation of visual information influenced the haptic perception of curvature. The uncertainty associated with the unimodal vision condition was smaller than that in the unimodal haptic condition, regardless of whether the haptic information was procured actively or under robot assistance for curvature detection. When both visual and haptic information were available, the uncertainty was not reduced; it was equal to that of the unimodal haptic condition. The weighting of the visual and haptic information was highly variable across subjects with some subjects making judgments based largely on haptic information, while others tended to rely on visual information equally or to a larger extent than the haptic information.
