Great article Jason. I really admired how you blended the theoretical with the practical aspect. Wish HCI books had this type of explanation :) Cheers and well done!

Great article, it is still an area that web designers and developers need to learn to incorporate much more in their actual client work. since it helps to satfisfy clients all the more.

hi, with regards to Grouping Items, you might be reducing movement time to click on either Home or Blog but what about accuracy i.e. clicking the right button when there’s no space between them? particularly with a touchscreen interface?

Was going to point out about the edges, but @Alex beat me to it. Tog also has a useful article about Fitt's Law that's worth reading.

Great article, thanks for sharing.

I would like to point out that there is an extension to the “5 magic pixels” concept. In fact, a screen offers more than that:
- 4 edges (the vertical and horizontal lines that create the boundary of the screen)
- 4 corners (the intersections of those lines)

It is easy to hit an edge, and at the same time it is very easy to hit a corner, rather than an edge.

This doesn’t really apply to web-sites, but this is a common practice in desktop applications.

Examples:
- Windows 7 uses the edges to resize a window (left side, right side or full screen)
- Windows 7 uses the lower right corner as a ‘show desktop’ trigger
- Compiz on Linux starts an Expose-like window switcher if you move the mouse to a corner

Which is the correct equation for Fitt’s Law? The one here uses (2 x D/W) but Wikipedia says (D/W + 1).

Makes sense. Before reading this article, I never considered the time is so important in context of completion of certain event. For e.g. Submit form. I am sure having larger button will certainly increase user experience as I don’t need to concentrate and take the mouse curson to specific relatively small button area. Good Post :)

Another really good article from Six Revisions. Things are picking up this week with some really informative subjects with strong content.

I had not looked at these concepts before, now if I can avoid re-writing everything I have ever done…
