Multiplatform virtual environment (VE) development is fast-becoming a realization for todayâ s developers. 3D user interfaces (3DUIs) can easily be ported to a variety of VE systems. However, few researchers have addressed the need to intelligently migrate 3DUIs across VE systems. We claim that the naÃ¯ve migration of 3D interaction techniques (3DITs) to other VE systems could result in decreases in usability. We also claim that device specificity can be used to increase usability on these other VE systems. In this thesis, we have chosen three manipulation 3DITs to naively migrate across a set of four VE systems. We use an exploratory usability study to identify any usability issues stemming from our naÃ¯ve migrations. After finding decreases in usability in select migrations, we redesigned two of the 3DITs for device specificity. We investigated the benefits of our redesigns with usability studies on the original, naÃ¯ve, and redesigned implementations of both 3DITs. Results from our studies are mixed. In one case we demonstrate that device specificity can be used effectively to increase 3DIT migratability. As a result from our experience in this work, we have learned several lessons in device-specific design as well as 3DIT migration.
