新生或是遊客來到一個陌生的校園所面對的第一個問題，那就是方向的問題， 而紙張的校園導覽不僅可能會有看不懂或是不夠詳盡的問題，更造成了許多紙張的浪費，這些紙本的校園導覽地圖，很可能僅僅是被使用一次之後就被丟棄，那麼如果將其改成電子的呢?更讓其行程只要輸入想去的地方就可以幫你自動找尋最佳的路徑的APP呢? 這個APP在戶外可以使用GPS衛星定位來達到高準確度的定位。在你打開APP之後，首先使用者必須先選擇目前所在的地方為室內或者室外，這樣可以使得我們程式能精確的切換室內外的定位方式，之後可以先從下拉式選單來選擇你目的地的大範圍(例如:理工學院、師範學院、人文學院....等等)，選擇完你的大範圍之後再選擇小範圍的部分(例如:哪一間教室)，選擇完畢之後APP將會運用A*路徑演算法來計算最佳路徑。 如果到了室內GPS收不到的範圍，APP則會提醒使用者必須切換室內外定位。在螢幕下方有一顆室內外的開關，只要將其打開則會切換成Wi-Fi定位和感測器定位來輔助定位使用者所在的位置。使用者可以透過手機螢幕上的提示訊息來讓使用者知道是否到達自己的目的地。當使用者看不懂地圖的時候也可以跟著螢幕左下角所顯示羅盤指針方向走即可，這樣可以讓人們更輕鬆地找到自己想去的地方，並且也能更盡興地遊覽這個校園。

The first problem faced by freshmen or tourists when they come to an unfamiliar campus is the problem of direction. The paper-based campus tour may not only have problems that are not understandable or not detailed enough, but also cause a lot of paper waste. These paper-based campus navigation maps are likely to be discarded after being used only once. So what if you change it to electronic? How about an APP by just entering the place you want to go, then you will find the best route automatically? This APP can use GPS satellite positioning outdoors to achieve high-accuracy positioning. After you open the APP, the user must first select the current location as indoor or outdoor, so that our program can accurately switch the indoor and outdoor positioning methods. After that, you can select a large range of your destination from the drop-down menu (for example: Polytechnic, Normal College, Humanities College... etc.). After selecting your large area, select the small area (for example: which classroom). After the selection is completed, the APP will use the A* path algorithm to calculate the best path. If it reaches the range that the indoor GPS cannot receive, the APP will remind the user to switch indoor and outdoor positioning. There is an indoor and outdoor switch at the bottom of the screen. When it is turned on, it will switch to Wi-Fi positioning and sensor positioning to assist in locating the user’s location. When users can’t read the map, they can follow the compass pointer displayed in the lower left corner of the screen. This will make it easier for people to find where they want to go and visit the campus more enjoyable.
