散步是健康生活中必不可少的活动，如果一起散步，就不会那么累，也会更愉快。我们在进行充分的体育锻炼时遇到的共同困难，例如缺乏动力，可以通过利用其社会方面来克服。然而，我们的生活方式有时让我们很难找到时间和那些住得离我们很远的人一起去散步。在这篇论文中，我们提出了一种新的系统，通过在不同地方行走的两个人之间的步态频率流，增加相互存在感，使人们能够进行“远距离社交步行”。使用者脚踝处的震动显示了拍档在脚后跟撞击时的感觉。为了在两个用户的实验中实现上述目标，我们设想了一个四步增量验证过程:i)单个步行者必须使用软件生成的虚拟参考来适应步行者的步频;ii)单一使用者须遵从预先设定的时变步态;iii)领导者-跟随者场景，其中触觉驱动是单向的;iv)一个双向触觉通信的点对点案例。我们一共对50人进行了仔细的实验验证，证实了我们的系统在每个场景中感知伴侣步态的有效性。

原文题目：Wearable Haptics for Remote Social Walking

原文：Walking is an essential activity for a healthy life, which becomes less tiring and more enjoyable if done together. Common difficulties we have in performing sufficient physical exercise, for instance the lack of motivation, can be overcome by exploiting its social aspect. However, our lifestyle sometimes makes it very difficult to find time together with others who live far away from us to go for a walk. In this paper we propose a novel system enabling people to have a ‘remote social walk’ by streaming the gait cadence between two persons walking in different places, increasing the sense of mutual presence. Vibrations provided at the users’ ankles display the partner’s sensation perceived during the heel-strike. In order to achieve the aforementioned goal in a two users experiment, we envisaged a four-step incremental validation process: i) a single walker has to adapt the cadence with a virtual reference generated by a software; ii) a single user is tasked to follow a predefined time- varying gait cadence; iii) a leader-follower scenario in which the haptic actuation is mono-directional; iv) a peer-to-peer case with bi-directional haptic communication. Careful experimental validation was conducted involving a total of 50 people, which confirmed the efficacy of our system in perceiving the partners’ gait cadence in each of the proposed scenarios.
