Information contains numerical and parametric data and other information. This data can help users relate between the picture they see and the numerical data, and understand the relation between distance, motion and time. (Yair, Mintz & Litvak, 2001)
The Rationale Behind the Feature (Specific Design Principle):
The Virtual Solar System is a non-immersive 3D virtual environment. The user flies in the solar system by the computer mouse as a spaceship. While “flying” and navigating, the user can read information about a specific object by touching it (see figure). The goal of this data is to represent information that can not be represented visually, without changing the global picture on the computer screen. This way it does not capture the user’s attention.
