隨著電視牆及電子看板的廣泛設置，商家或是企業主想要提供資訊給顧客可以說是一件相當簡單的事情。然而，這些看板因為缺乏和使用者之前的互動，造成其所提供的資訊有可能輕易的被消費者所遺忘或是忽視。因此，若想要強化消費者與看板上廣告及訊息之間的連結，或許可以透過增加使用者參與的方式，來加深使用者對看板訊息的興趣和印象。綜上所述，本篇論文便推出了一個結合數位螢幕和智慧型手機的系統來完成在看板訊息和使用者之間的互動模式。本系統讓使用者可以直接地和電子看板進行互動，並擁有容許多使用者在同時間下的互動模式。除此之外，本論文亦實作了一個在本系統架構下的餐廳訂位系統，讓消費者可以透過手機 App來連結智慧型看板，並透過指令來了解候選餐廳目前的排隊人數，再對心儀的餐廳進行訂位；本餐廳訂位系統能夠讓多位使用者同時完成上述的操作。本次論文的實作是在Android系統上實行。

With the widespread deployment of digital signage and the screen wall, it is really easy for any organizations or business side to put some information to the customers. However, the customer could forget the news they saw on the screen most of the time due to the lack of interaction. In order to make the connection between a customer and the information on a display stronger, encouraging user engagement is a worthy way to try. Consequently, this thesis proposes a system combine digital signage with smartphone to achieve the interaction between the user and signage information. Unlike the current existing signage system, the proposed system allows multiple users to interact with the digital signage. According to the proposed system structure, a restaurant reservation system is implemented. The user can use an android smartphone app to connect with our digital signage, which shows the restaurant information in a department store. Once the connection is built, the user can check how many reservations the restaurant in which they are interested has. A user can also make a reservation for the prefer restaurant anytime as long as the connection existing. The system provides the capability for more than one user. Different users would have their own moving cursor; therefore, users could control the signage at the same time. The app is implemented on Android System while the signage system is implemented on Windows System.
