Abstract
This paper describes education support system for mechatronics using marker free augmented reality technology. The system aims to offer useful information for the learner, to support intuitive study, and to improve the efficiency of the in-depth understanding and study. For the purpose the system that synthesizes information that seems to improve study to the image of the reality on real time was developed using marker free augmented reality technology to mechatronics training, and study. The education support system haves function to show explanation and datasheet of parts of the mechatronics system for learner when the learner click the parts through the display and to show circuit diagram on real image at leaner's request.
