This demonstration will illustrate an interactive immersive computer game, POMY, designed to help Korean speakers learn English. This system allows learners to exercise their visual and aural senses, receiving a full immersion experience to increase their memory and concentration abilities to a greatest extent. In POMY, learners can have free conversations with game characters and receive corrective feedback to their errors. Game characters show various emotional expressions based on learners’ input to keep learners motivated. Through this system, learners can repeatedly practice conversations in everyday life setting in a foreign language with no embarrassment.
