The interface of the mobile learning resource is the window for learners to interact with learning content and it can affect learners' experience and engagement through multiple sensory channels. This paper first identifies the influencing factors of learning engagement in mobile learning environment by literature analysis, interview and questionnaire survey. Then through expert evaluation, the highly influential and interventional factors of interface design are clarified. Finally, based on ICAP framework, this paper proposes a hierarchical model of mobile learning resource interface design. According to that model, the interface design is divided into sensory level, behavioral level and emotional level to meet learners' sensory needs, interactive needs and emotional needs respectively, and trigger their different levels of learning engagement as well. Owing to that model, some strategies for interface design of mobile learning resources are proposed. The structure of both interface and knowledge content should be matched to adapt to learners' cognitive characteristics. The design of learning scaffolds should pay attention to its effects on learners' visual, auditory, tactile and other senses, and a multi-channel supported the learning scaffold is necessary to satisfy learners' deep learning needs. In order to arouse learners' sense of immersion and high degree of engagement, it is suggested to design a three-dimensional interactive interface and construct a natural human-computer interaction mode. Moreover, the display and coordination of the aesthetic, emotional and cognitive functions of the color should be stressed to optimize the learning experience and enhance the learning effect.
