In today's technology, 3D presentation is vital in conveying a realist and comprehensive understanding of a specific notion or demonstrating certain functionality for a specific device or tool, especially on the World Wide Web. Therefore, the importance of this field and how its continuous enhancement has become one of the dominant topics in web development research. Virtual Reality (VR) combined with the use of a 3D scene and 3D content is one of the best delivering mechanisms of this realist ambience to users. AquaFlux and Epsilon are clinical instruments that were built, designed, and developed at London South Bank University as research projects for medical and cosmetic purposes. Currently, They have been marketed and used in almost 200 institutions internationally. Nevertheless, considering the type of these tools, they often involve on-site thorough training, which is costly and time-consuming. There is a real necessity for a system or an application where the features and functionalities of these two instruments can be illustrated and comprehensively explained to clients or users. Virtual User Manual (VUM) environment would serve this purpose efficiently, especially if it is introduced in 3D content. The newly created system consists of a detailed virtual guide that will assist users and direct them on how to use these two devices step-by-step. Presenting this work in a VR immersed environment will benefit clients, user and trainees to fully understand all the features and characteristics of AquaFlux and Epsilon and to master all their functionalities.
