In order to analyze spatial linear navigation through a task of self-controlled reproduction, healthy participants were passively transported on a mobile robot at constant velocity, and then had to reproduce the imposed distance of 2-8m in two conditions: "with vision" and "without vision". Our hypothesis was that the reproduction of distances would be longer with than without visual information. Indeed, with visual information the reproduction of all distances was overshot. In the "without vision" condition the reproduced distances were quite close to the imposed ones, but only for the shortest distances (2 and 4m) as the longest ones were clearly undershot. With vision the reproduction error was less than 10% for all distances; however the error could be smaller without vision at short distances, and therefore vision was not necessary.
为了分析通过自我控制的重复任务进行的空间线性导航，健康参与者被被动地以恒定速度运送到移动机器人上，然后必须在两种条件下重复施加的距离 2-8 米：“有视觉”和“无视觉”。我们的假设是，有视觉信息的距离复制会比没有视觉信息的距离复制更长。事实上，有视觉信息时，所有距离的复制都超过了预期。在“无视觉”条件下，复制的距离与施加的距离非常接近，但仅适用于最短的距离（2 和 4 米），因为最长的距离明显不足。有视觉时，所有距离的复制误差都小于 10%；但是在短距离时，没有视觉时的误差可能更小，因此视觉不是必需的。
