User interfaces evolve at a previously unseen pace, becoming more and more user-interactive. Hot-tracking is one of the latest technologies added to the user interface interactivity. Hot-tracking is a user interface concept that provides a visual effect where elements of user interface such as buttons, etc., react to user interaction. Most commonly, the effect works by highlighting GUI elements when the mouse cursor is over, showing them precisely where they are over.





Widely introduced with Microsoft Internet Explorer 3, hot-tracking toolbars quickly found their place in many applications from browsers to Office products. While flat toolbars with hot-tracking enabled sure look more impressive than the older, traditional ones, the usability effect of hot-tracking is more than just looks. Applications with hot-tracking feel more responsive and provide better feedback to the user, providing overall a more pleasant usage experience.

Historically, first enabled applications used monochrome toolbars as 'regular', only displaying a single 'hot' button in color when the mouse cursor was over it. Since then, a more vivid approach to user interfaces prevailed, displaying all buttons on a toolbar in color, and highlighting a 'hot' button in a different manner.

From the designer perspective, there are several states of to be drawn, representing the various states of user interface elements. There are normal, and 'hot' versions of each to be designed.

When designing an application, it is essential to provide all versions of icons for best possible usability. But what if your product comes with hundreds of images? Do you have to each single one of them in all the three states? In a word, yes; but it's not necessary that you do it by hand. There exist special products for designing icons aimed at producing all three versions out of a single 'normal' original.

The latest version of recognizes the need, and makes it possible to automate the process of designing 'hot' versions of icons. The product produces 'hot' versions of icons for hot-tracking completely automatically by applying the Hot effect, thus making it possible for designers to concentrate on drawing unique images instead of drowning in technicalities. The effect, as implemented in IconLover, is more realistic and pleasant-looking than any 'hot' version of a toolbar than the default Windows implementation of hot-tracked items.
