Abstract
The 3D talking-head mobile app is a type of mobile app that presents the head of a computer generated three-dimensional animated character that can talk or hold a conversation with human users. It is commonly used for language learning or entertainment, thus the quality of the mobile app is determined by the accuracy and the authenticity of lip synchronization and facial expressions. A typical 3D talking-head mobile app is structured by six key components, i.e., animated 3D head model, voice over scripts, background audio, background graphics, navigational buttons, and instructional captions and subtitles. When the app is meant for educational purposes, the integration of these components requires proficiency in creating an animated 3D talking head, authoring a mobile app, and understanding pedagogical principles for mobile assisted language learning. The mastery of scientific knowledge in these areas is essential to keep abreast with the advancement of mobile technologies and future research direction.
