隨著網路的進步，網路交友也逐漸興盛。人們依靠網路上的媒體資訊來了解其他人，並透過這些媒體來與其他人聯繫。然而，人們自然的交友方式並非如此，以往人們因為某些接觸而相識，因屢次的相遇而熟識。彼此的生活是有所交集而逐漸變成朋友，網路的發展應是來維繫這些友誼而非取代過往的交友形式。
本研究的主要目的是希望透過行動科技的協助讓人們回歸自然的交友習慣。因此本研究建構一手機應用程式moFriends，來取得人與人之間實體互動與虛擬溝通的平衡點。利用“地點”跟“時間”兩個參數，篩選出與自己十分有緣的人或生活型態類似，我們稱之為“熟悉的陌生人”。本研究利用手機做為探針，找出用戶身邊熟悉的陌生人，建立與這些潛在朋友之間的關聯。

With the developing of the Internet technology, it brings with lots of convenience to us that we can do lots on the Internet. Therefore, the life -style of modern people had changed, and the ways they make friends also become different than before. When people trying to get familiar with someone interested only relays on the personal information showing on the net, and the connections between two people just depend on the Internet media. But the way of making friends in the past is totally on the contrary from now.
In this study, the goal is arousing the human nature of making friend, a mobile service will be provided to balance of virtual community and physical interaction. Try to sieve out the familiar strangers by ”Location” and “Time”. The mobile device serves as a probe for aware the familiar strangers around us, and bridging us via it.
