Experimental Testing of The Roblox Platform for Control System GUI Design

This research focuses on the design of a two-dimensional-based control system using Roblox Studio, a metaverse platform that has been proven to provide learning facilities in engineering. This research is conducted using two testing methods: direct testing in the Roblox application and testing using the Black Box testing method in the Roblox Studio. The testing is performed step by step, starting from testing user interactions with the system, testing GUI's ability to respond to user inputs, testing the ability to implement mathematical functions and display them in text form, and testing Roblox's capability to display these functions in simple graphic form. The design results can then be tested by analyzing the system's output in the form of mathematical calculations and how these results are shown through the designed two-dimensional interface. There is no direct correlation between mathematical calculation results and the aesthetics or comfort of the systems' GUI. Errors in such simple mathematical operations can be one factor in the occurrence of errors in open-loop systems. Roblox is highly recommended to provide more dynamic functions on BillboardGUI so that developers can have more options in their design activities.
