Building a Remote Laboratory Based on NVIDIA GeForce Experience and Moonlight Streaming

Innovations in Internet technology have led to new forms of teaching and learning. Online education is one of the most exciting innovations. In the current period, the COVID-19 pandemic has made the need for online learning more prominent and essential to avoid contact and gather many people. In online courses, students can not only do distance learning but also conduct experiments using a remote lab. The implementation of remote experiments that use hardware or have high requirements for real-time has been studied recently. However, there is still a lack of a flexible, easy-to-deploy and effective solution. This article presents a new case study for remote labs utilizing a combination of labs and NVIDIA GeForce Experience and Moonlight Streaming. On the server-side connected to the practical KITs, NVIDIA GeForce Experience enhances video quality. It reduces image rendering latency by using the GPU to encode streaming video, while the client is custom programmed software based on Moonlight PC - an opensource NVIDIA Gamestream Client. Furthermore, this work set up a prototype to illustrate the entire proposed system.
