Toward Specification Techniques for Pre-Screen Projection and Other Next-Generation User

摘要

We have investigated new languages for describing and implementing next-generation interfaces that might be used in 3-D visualization environments. Working with researchers at NRL Code 5513, we learned about the interfaces they are currently developing and are planning for future work. For current work we examined pre-screen projection and foot control; and we discussed future plans for research in 3-D manipulation, such as 3-D route planning and object-based 3-D visualization. We then studied how new specification languages might capture these types of interfaces and described an approach and conceptual model for doing this. We began with a model and language that combines discrete and continuous interactions, which is described in detail in this report. In collaboration with NRL researchers, we considered its applicability to NRL's 3-D user interface designs. We also began exploring the issue of how to connect the user interface component to a simulation component of a 3-D visualization system.
