隨著智慧型手機及行動網路的蓬勃發展，人們可以隨時隨地與世界各地的人進行聯繫，而交友服務也藉著智慧型手機上簡單直覺的操作方式發展成行動交友應用程式，讓交友行為變得既簡單又有效率。但在市面上的主流行動交友應用程式所提供的交友流程差異卻不大，其中有非常多數都是先提供候選配對對象的長相及基本資料再讓使用者決定是否進一步交流的模式，因此，我們希望瞭解目前主流的交友模式是否適合多數有交友意願的使用者，以及瞭解不同的人機互動介面或功能是否能增進交友體驗。

　　本研究進行的方法是透過設計線上問卷來收集有使用行動交友應用程式經驗的受訪者回應，在2016年11月21日至27日期間，共收集到509份有效樣本。透過統計結果，我們發現不同性別對於主流行動交友應用程式需提供的長相資料有兩極化的看法。而我們也進一步瞭解到提供客觀的事實資料，如雙方的共同朋友資訊，即可以改善對於平台上不熟識對象的不信任感。我們也藉由討論移植自即時通訊應用程式的熱門功能至行動交友應用程式的相關問題來瞭解這些不同的功能及人機互動介面是否能進一步增進交友體驗。其中我們發現，多數的受訪者認為在即時通訊應用程式中評價兩極的已讀提示功能能夠增進行動交友應用程式互動階段的交友體驗，但有些應用於即時通訊應用程式的功能並不適合應用在交友服務上，如群聊、閱後即焚訊息等。

Nowadays, people can contact with people living on another side of earth easily by smartphone and mobile network. The friend-making behavior starts to move the mobile platform. Friend-making apps provide intuitive gesture operations to make friend-making easier and more efficient. However, the flows of mainstream friend-making apps are little different from each other, so we want to understand if this friend-making flow is suitable for most of the users, and what HCI component can improve the friend-making experience.

We created an online questionnaire to collect the responses from users who have used one of mobile friend-making apps from November 21, 2016 to November 27, 2016, and there are 509 valid responses. We found females really mind they are seen by strangers on the apps so they are unwilling to provide portraits or interact via video. And, providing objective information, like mutual friends, is helpful to reduce the mistrust of users on friend-making apps. We also consider to applying some popular functions from instant messaging apps to friend-making apps. Most of the respondents agree the "read" sign is helpful to make friends but group chat and self-destructing message are not suitable for friend-making apps.
