本文提出了两种不同的方法来控制人类步行节奏之间的比较，进一步的目的是评估用户是否可以同步到建议的节奏，低的努力，同时执行其他任务。弹性触觉带用于在旨在再现真实的工业或人-机器人协作任务的练习期间建议行走速度。该系统由两个可穿戴接口提供定时信息给用户，和一个压力传感器估计的真实的步态模式，从而导致在步行状态监测和振动触觉刺激相结合，以调节步行速度。根据所需的步行节奏，交替地和重复地向人体的右侧和左侧给予具有恒定呈现间隔的振动刺激。我们测试了两种不同的接口位置：手腕和脚踝。在脑力和体力负荷下，使用额外的任务对制导系统进行了评估：在平面中心平衡一个小球体。实验结果表明，受试者更喜欢脚踝的位置，因为它涉及到穿着，舒适性和容易执行任务。所提出的方法在日常使用中的例子是体育，康复和人机合作和互动的训练和教练。
This paper presents a comparison between two different approaches to control human walking cadence, with the further aim to assess if the users can synchronize to the suggested rhythm with low efforts while performing other tasks. Elastic haptic bands are used to suggest walking-pace during an exercise aimed at reproducing real industrial or human-robot cooperation task. The proposed system consists of two wearable interfaces for providing timing information to the users, and a pressure sensor to estimate the real gait pattern, thus resulting in a combination of walking-state monitoring and vibro-tactile stimuli to regulate the walking pace. Vibrational stimuli with a constant presentation interval are alternately and repeatedly given to the right and left side of the human body, in accordance with the desired walking cadence. We tested two different interface placements: wrists and ankles. The guidance system has been evaluated under mental and manual workload using an additional task: balancing a small sphere in the center of a flat surface. Experimental results revealed that subjects prefer the ankle position for what concerns wearability, comfort and easiness in task execution. Examples of the proposed approach in daily use are training and coaching in sports, rehabilitation, and human-robot cooperation and interaction.
