An Approach of Holographic Technology for the Practical Distance Education

ABSTRACT

In order to face the requirement of distant education after covid-19, this paper has presented a cyber-physical co-existence environment for practical distance learning events, we called it as a “Co-existing Practical Environment, CPE”. CPE includes “Holographic Wearable Device, HWD” for behavior sensing and vision sharing mechanism, cloud “Digital Twin Model, DTM” database for expert correcting variables real time, and collaborative fabrication discussion interface. We built an immersive HoloLens interface to help distance learning participators, understanding the concept of structural mechanics form morphs with mix-reality sensing, communicating the augmented information of parts of models for collaborative fabrication, and sharing the views of operation process for lecturers to solve the technical problems instantly. Furthermore, users are able to make their own custom digital twin project in CPE and optimize their fabricating process by adding more realistic material factors, operation callbacks, or analyzing their practice results in parameters relationships. This paper revised an application of holographic technology with a practical distance learning workshop as example, and discover CPE as a new kind of co-creation, cross-field, and remotely prepared cooperation mechanism. While the epidemic is still ragging, we are looking further researchers of more immersive methods for distance education. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
