In view of the benefits of and success in acquiring multiple languages in an immersive learning environment while young, this research aims to create an immersive language learning environment for young children to acquire multiple languages utilizing robots and IoT (Internet of Things) -based toys. This paper presents the results from the first two stages of this project aiming to develop a design framework to guide the development of such an immersive environment. Our extensive review of the relevant literature indicates that the framework should, at least, consist of five main pedagogical considerations: language input, activity design, interaction design, toy design and robot design. In each of the five dimensions, a number of key factors should also be addressed in creating an effective learning environment. The development of the design framework is to serve as a road map providing design principles and guidelines for educators and researcher to create an immersive learning environment.
