Designing a web based non-immersive Virtual Environment Application (WB-NIVEA) for diagnosing dyslexic children' potential

Developing virtual reality applications is more challenging compared to developing 2D or 3D multimedia applications as the former requires greater design details. The challenge becomes more intense when the VR applications will be deployed in diagnosing tasks. Against this backdrop, this paper discusses the design of VR application called `Web Based-Non Immersive Virtual Environment Application' (WB-NIVEA) that will be used to diagnose dyslexic children's potential. The design principles of WB-NIVEA is based on Sutcliffe's VR methodology, involving a series of phases: i) determining the type of VR, ii) selecting the appropriate modalities and interaction devices, iii) creating and modeling the 3D objects, iv) creating the proper terrains, and v) determining the type of agent. To make WB-NIVEA more robust, several optimization techniques were utilized. The design approach used in designing WB-NIVEA can be used as guidelines by application developers to develop non-immersive desktop virtual reality applications.
