Abstract
An interactive system based on computer vision technology for food and agricultural education is proposed, on which knowledge of food cuisines can be learned by game playing using object-based tangible interfaces. Specifically, cuisines with their ingredients are projected onto an interactive projection table for the user to learn when specially-designed objects attached with light-reflecting stickers are placed on the table and recognized by the system. Such objection recognition is realized by analyzing the shapes of the stickers appearing in the IR images taken by an infrared filter camera. The system was exhibited and observations of the users’ performances as well as interviews with experts and the users were conducted. The collected data were used to evaluate the effectiveness of the system to reach the following conclusions: 1) the use of computer vision technology to carry out human-machine interaction offers a novel and interesting experiencing process; 2) the object-based interface helps the participants fit into the context of education; 3) the interactive experience of performing the system is appealing and amusing; and 4) the adopted projection mapping approach could be combined with richer dynamic images and more knowledge contents to enhance the educational effect.

Keywords
food and agricultural education, human-machine interaction, computer vision technology, interactive game playing, object recognition.
