散步是健康生活中必不可少的活動，如果一起散步，就不會那麼累，也會更愉快。我們在進行充分的體育鍛煉時遇到的共同困難，例如缺乏動力，可以通過利用其社會方面來克服。然而，我們的生活方式有時讓我們很難找到時間和那些住得離我們很遠的人一起去散步。在這篇論文中，我們提出了一種新的系統，通過在不同地方行走的兩個人之間的步態頻率流，增加相互存在感，使人們能夠進行「遠距離社交步行」。使用者腳踝處的震動顯示了拍檔在腳後跟撞擊時的感覺。為了在兩個用戶的實驗中實現上述目標，我們設想了一個四步增量驗證過程:i)單個步行者必須使用軟體生成的虛擬參考來適應步行者的步頻;ii)單一使用者須遵從預先設定的時變步態;iii)領導者-跟隨者場景，其中觸覺驅動是單向的;iv)一個雙向觸覺通訊的點對點案例。我們一共對50人進行了仔細的實驗驗證，證實了我們的系統在每個場景中感知伴侶步態的有效性。

原文題目：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.
