QR碼 (Quick Response Code) 是二維條碼的一種,具有易於辨識及良好的容錯能力, 因此有很多衍生的應用。智慧型裝置則是近年來越來越普及,幾乎已達人手一機的情況。本論文利用 QR 碼的特性,以及智慧型裝置的普及,實現一個快速的點名系統雛形,可以取代傳統的上課點名。教師開啟伺服器網頁,產生課程的QR碼,學生透過專用APP掃描QR碼,即可完成點名。所有學生的點名動作,可以在同時間完成,且出席記錄會保存在雲端伺服器中,方便教師隨時隨地查看及管理。此系統具有快速點名的優點,能夠減少傳統點名所浪費的時間,幫助教師了解及掌握課堂出席的狀況 ,以提升教學之品質。
Quick Response (QR) Code is a two-dimensional bar code, which is easily scanned with good fault tolerance, and nowadays there are a lot of derivative applications. On the other hand, smart devices are becoming increasingly popular in recent years, and almost every young student has one in hand. In this thesis, we design a fast roll call system prototype based on QR codes for Android smart devices. A teacher opens the web page of the server which generates the QR code with course information, then each student scans the QR code with his smart device to complete the roll call action. The results of all students attendance are completed at the same time and the attendance records are stored in the cloud server for later access and management anytime and anywhere. The system has the advantage of rapid response when compared to the traditional method. It helps teachers to quickly grasp the attendance situation of the classroom in order to improve the quality of teaching.
