Just read an interesting discussion in one of the blogs at http://www.acm.org.

On the Importance of Replication in HCI and Social Computing Research, by Ed H. Chi:

From the blog:
> In the second experiment, when restricted to retrieval tasks rather > than including comparison tasks also, Hyperbolic Browser was faster, > and users appears to learn more of the tree structure than Explorer. >
> What’s interesting is the interpretation of the results suggest that > squeezing more information onto the screen does not improve subject > perceptual and search performance. Instead, the experiment show that > there is a very complex interaction between visual attention/search > with density of information of the display. Under high scent > conditions, information seems to ‘pop out’ in the hyperbolic browser, > helping to achieve higher performance.
