What are some alternatives to “hover” on touch-based devices?
I'm building a standard infographic where you mouse over a region and the image changes as you move. For instance, imagine a map of the world, and when you mouse over a country, that country glows and a panel shows statistics about that country. The implementation is to have a separate image for the glowing country, and a div element with the statistics, and the code shows these additional elements on a hover over the country.
The question is: what should this do on a tablet, where there's no hover event? What's a good alternative navigation metaphor for this kind of situation on touch-only devices?
