introduction: hospital portals, as the first virtual entry, play an important role in connecting people with hospital and also presenting hospital virtual services. the main purpose of this article was to suggest a conceptual model to improve tehran private hospital portals. the suggested model can be used by all the health portals that are in the same circumstances and all the health portals w...

Our goal is increasing the users’ value and experience and decreasing the implementation time for web portals. To achieve this goal we adopt a subject-centric perspective on information architecture. The fundament of this approach is that portals should be driven by subject-centric models of the portals’ domains. Out of these domain models, the interaction and interface design of the portals is...

We are investigating methods to accelerate rendering of architectural walkthroughs. In this paper, we improve upon a cells and portals framework by using images to replace geometry visible through portals (doors and windows) in a three-dimensional model. We present several solutions: images texture-mapped onto the portal, 3D warping of single reference images, and 3D warping of layered depth im...
