Application development to learn the degree of roasting and the coffee producing countries with a coffee roaster

Abstract

Mechanical engineering has often developed by fusing with information technology in recent years. We have been developing a coffee roasting machine for mechanical engineering education. We can study machine design, metalworking, and heat transfer engineering in the process of developing a coffee roasting machine. In this paper describes an application development to learn coffee roasting degree and coffee bean production area. In the application to learn the roasting degree, click on the image of the roasted beans according to the button of the eight roasting degrees and explain the roasting degree by computer voice. In the application to learn the production area indicates the position on the map with a marker by clicking on the major coffee producing countries in the world, and explains the characteristics of the coffee production area by computer voice.
