Construction of Interactive Teaching System for Course of Mechanical Drawing Based on Mobile Augmented Reality Technology
Keywords:Augmented Reality, Mechanical Drawing, Interactive teaching system, multimedia teaching application
The teaching aim of Mechanical Drawing is to cultivate the students' graphics interpreting ability, plotting ability, inter-space imagination and innovation ability. For engineering students in China Universities, Mechanical Drawing course with the characteristics of 3D and 2D inter-space transformation, is often difficult to master. The ordinary dull teaching method is not enough for stimulating students’ spatial imagination capability, interest in learning, and cannot meet teachers’ teaching needs to explain complicated graphs relationships. In this paper, we design an interactive teaching system based on mobile augmented reality to improve the learning efficiency of Mechanical Drawing course. To check the effect of the proposed system, we carried out a case study of course teaching of Mechanical Drawing. The results demonstrate that the class for which interactive teaching system based on mobile augmented reality technology was adopted is significantly superior to the class for which the ordinary dull teaching approach was adopted with regard to the degree of proficiency of course key and difficult points contentï¼Œspatial imagination capability, students’ interest in learning and study after class, especially in respect of students’ learning interest and spatial imagination capability.
