Learning should be more effective in real-world situations. Language learning also has important dependence on the same situation. Bruno believes that “successful foreign language classroom teaching should create more situations in the class, giving students the opportunity to use the language materials they have learned.” The importance of context makes situational teaching It has long been a hot topic in foreign language teaching research. So far, many situational teaching modes and methods have been proposed, and it has also effectively guided the practice of foreign language teaching. The key factors that should be included in the language teaching situation are: cultural context and contextual context. The language classroom teaching situation should include both contextual context and cultural context. However, due to the constraints of classroom teaching conditions, some hidden contextual factors are inconvenient and effective to display. Only by means of virtualization technology can be used to assist the realization. Language immersion, the learner is placed in a real language context to experience the language, perceive continuous language input, and guide language output. Classroom virtual teaching situations can be built through Kinect somatosensory interaction technology to enhance language immersion. Guided by the situational cognitive learning theory, this paper analyzes and designs the virtual classroom context elements of the English classroom to realize the Kinect virtual situation creation system. For example, when teaching English as a second language, teachers or students collect or produce contextual material (pictures, audio and video, 3D scenes) related to the subject of the lesson before class, and explain the content in English. Kinect captures the body of the commentator. Pose and voice, and incorporate the narrator into the virtual scene through background recognition and character avatars. The commentary can be done in class or in the classroom before class. This kind of role as a "news anchor" or "narrator" can be explained on the spot, so that teachers and students can feel immersive. In addition, perform character play with virtual dolls. The virtual doll (Avatar) is the embodiment of the learner in the virtual scene. The learner can manipulate the doll through his own ideas. In addition to the basic gestures, he can also recognize subtle facial expressions, such as mouth opening or eyebrows. And react it to the virtual doll. Students can hold vivid and live virtual doll talk shows in their own situational dramas, or manipulate different figures to complete character performances. The Kinect virtual situation creation system has an active auxiliary role in creating teaching situations such as situation, experience situation, deductive situation and reflective evaluation. Kinect somatosensory interaction technology can create a realistic situation for classroom teaching, and has practical significance for improving the contextualization and abstraction of traditional classrooms, enhancing students' learning motivation and learning interaction. Compared to professional situational teaching systems, Kinect is inexpensive and easy to integrate with existing multimedia systems or language teaching systems.]]> 2018-12-03 06:00:32 UTC https://padlet.com/shanzhenglin/2zvyj0yp90m2/wish/310283029
