Every one knows Ipod’s success, the reason for its success is the usability of the product’s navigation. Inspite of the various options this object needs to perform, Apple people have made the best use of the wheel as navigation.
Very recently I have been working on a flash graph, where the space was constraint, all I had to do is look at the behaviour of the Ipod navigation menu, and I came with a small jogger/draggable control much like the slider but this own had negative and postive numerical values for it calculation.
When the user clicks and drags to the left it took negative values and moved to the right it gave positive values, when the leaves the slider the value would reset to Zero.
Hey I know, what is on your mind, “I have seen these controls before”. but for many of us, this one didn’t light up our brains. The idea what I am trying to say is look for things around you, you will get some cool ideas.
