Mouse over effect on touchscreen

Obviously you dont have a mouse over effect on a touchscreen, but I would like some effect, ma开发者_StackOverflow中文版ybe onclick? Does anybody have any suggestions?

On the touchscreen I'm working with right now, the mouse over is a persistent effect of clicks. In other words, it's as if after clicking an item with an actual mouse and releasing the button, one never moved the mouse pointer afterwards.
