3D interfaces could created simpler to use systems, using real-world physics and views. Advanced 3D designes provide rapid situational awareness, reduced numbers of actions and meaningful feedback for users. As shown by the evolution of games from 2D to 3D environments, the human mind processed 3D environments much more quickly and is able to understand what is going on much more quickly. 3D art and media experiences are becoming more popular on the internet and a standard has been created called X3D for such purposes. Several applications have been created that showcase the possibilities of using 3D in our every day desktop work environments.

Computer displays which concern 3D and 2D graphics are often misunderstood. Interfaces often described as being 2D, are actually 3D after further examining their layout. For example, overlapping windows or tabs require the users to have an understanding of 3D in order for this technique to be interpreted effectively. Without getting into too much detail, the author of this articles believes that it necessary to design with a combination of 2D and 3D concepts hence the articles title of "Designing with a 2 ½ D Attitude."

Navigating through a webpage can be frustrating to an end user if not designed properly. When the site has good graphics and links they are finding that the user will get more involved with the sites content. Before clicking on the link there needs to be an understanding where the link will take them so they feel the site has organization. Some designers find that too many links could confuse the user. They feel if they can use button bars users can navigate more easily.

2D is a better approach when building interfaces over 3D.  3D modeling needs to understand that the user will have to remember what was past and what may be lurking behind an object that is near them, and out of immediate view.  There is a good time to use 3D, when visual physical objects need to be understood in their solid state.  For example with new technology for surgeons performing a cut on a patient.  The body will be rendered in 3D with the location of a tumor in 3D.  This provides an easier method to understand the approach than a 2D X-ray would allow.  Another good example where 3D excels is with the entertainment industry, specifically the gaming industry.  3D excels because the user does not really want to accomplish any goals beyond being entertained.

This document is an overview of 3-D interaction and user interfaces. It goes in depth to explain three sections of 3D/2D as it relates to HCI: navigation, selection/manipulation, and system control. Furthermore, the document explains different approaches to User interfaces (UIs) & 3-D interaction design. Further into the document it compares and contrasts 2D and 3D interaction design.
