Virtual reality (VR) technology has novel, complex attributes such as realism and immersion that far surpass 3D multimedia applications, thus entailing appropriate development methodologies. In this study, the researchers propose a new development methodology based on the adaptation of Sutcliffe's VR development methodology in designing a diagnostic tool called Web Based Non-Immersive Virtual Environment Application (WEB-NIVEA), which would be used as a tool to diagnose dyslexic children’s potential in visual spatial field. The development of WEB-NIVEA was based on tasks analysis and domain models phases. Specifically, the analysis of task phases focused on three sub activities, namely application functions, interaction properties, and application activities.  In tandem, the analysis of the domain models helped the design and development of the tool using relevant environmental themes mediated by a virtual agent. To add a sense of presence, realism and interaction elements were employed to engage potential users, especially dyslexic children, to use this tool with ease and fun. Through heightened engagement, dyslexic children can diagnose their potential, so that appropriate learning path can be identified and enhanced to help these children learn efficaciously, thus helping them to embark on suitable careers later in their lives.Â
