Play is the basics of cognitive, physical, and emotional development of infants, and especially pretend play is very important in the aspect that it enhances imagination and expression of infants by drawing making up free imaginative story and physical expressions. On the other hand, on the effect of structural reality of toys used in pretend play on pretend play of infants, it is predominant that as the structure of the toy becomes higher, the pretend play is promoted. When it is connected to the environmental aspect of play of infants, it can be inferred that infants may be easily immersed in imaginative world using the fact that they are placed in play environment that provides detailed symbols about certain subjects. Also, as a technique to provide such environment, chroma key that realizes virtual learning environment may be used. Chroma key, one of image composition technologies, can be an effective means of enhancing curiosity, immersion, and expression skills of play activities by providing infants with realistic spatial background. Furthermore, sense of space is an essential basic ability to understand, interpret, and evaluate surrounding world, and virtual reality may help infants overcome physical and economic constraints of the existing child education institutes and raise their sense of space in safe environment. In addition, in order to use the chroma key technology effectively, it’s necessary to make infants understand about the chroma key and specialize teaching methods along with appropriate education plan.
