The type of task also affects people’s perception of depth cues when searching
a virtual environment. Risden et al. (2000) compared the behavior of engineers when
browsing a huge amount of internet information on conventional 2D browsers or on a
3D hyperbolic graphic interface and discovered that even if most engineers
consider the 3D interface to be better when searching within existing categories,
they preferred the 2D interface during search tasks for new categories. Perception
and action are intertwined, and to understand space perception (for visualized
interface designs), designers need to understand the purpose behind the information seeking
behavior. Risden et al. suggest that the two interfaces should be combined
to make an optimum visual presentation of the large amount of information found on
the internet.
