实时录播系统与虚拟现实技术在机能学实验教学中的应用探讨

Searching for the use of virtual reality and real-time recording technique in the functional ex-periment teaching

机能学实验对学生掌握疾病的发生机制和诊疗原则有重要意义。机能学实验教学中既要求学生掌握机能学手术技能，也要求其掌握复杂多变的机能学变化规律，因而机能学实验需要成为开放性课程。而虚拟现实技术和实时录播系统的应用为机能学实验开放提供了新的可能性。通过实时录播系统可以即时播放高清画质的实验操作视频，从而方便指导学生机能学手术操作。而根据目前虚拟现实技术的发展现状，其更适合在课前预习和复习考试等学生自主学习环节中应用；若能将开发重点放在实验拓展部分，则更能发挥其优势，将更多复杂的机能学变化展示出来，拓展教学深度。这些新技术的运用对机能学实验教学效果有一定提升作用。

Functional experiment plays an important role in understanding the mechanisms of diseases and principles of diagnosis and treatment. It requires students to master basic skills of func-tional operation, and complicated disciplines of functional alteration as well. Thus functional experi-ment needs to be an open course. The use of the virtual reality （VR） and real-time recording tech-niques provides potential for this exploration. By the way of real-time recording system, HD video of experiment operation is played, which helps guiding students to learn basic experiment skills; while based on the development status of VR technology, it is more applicable for learning by oneself, such as preview before the class and review for the test, and furthermore, the advantage of VR technique will be more apparent, if the key development focuses on experiment extensions to disclose more compli-cated functional alterations. This new technique helps to improve teaching effects of functional experi-ment.
