The design of 3D cyberspace as user interface: Advantages and limitations

Abstract

Virtual reality propagandists, technologists and the Internet community have long debated the issue of the usability of online three-dimensional (3D) environments. A lot of work was published about the benefits of 3D spaces for human-computer interaction and information visualisation due to their realism (Anders, Kalawsky, Crossley, Davies, McGrath, Rejman-Greene, 1998, Hamit, 1993, Heim, 1992, Aukstakalnis, Blatner, Roth, 1992). This topic also receives continuous industry support including standardisation of Virtual Reality Modeling Language ( VRML, VRML Consortium, 1997) and the more recent Macromedia & Intel alliance to bring web 3D to the mainstream (200 1, Intel Corporation). The actual implementation of this technology is, however, still challenging (McCarthy & Descartes, 1998) and minimal because 3D is too new and waiting for good design to be discovered (Nielsen, 1998). The practical aim of this project is to fulfil the niche by creating a functional 3D interface for the access of two-dimensional (2D) information, such as text, using VRML. The theoretical aim is to contribute to further research into 3D usability by describing and analysing the design process in terms of possibilities, challenges and limitations
