Less than 100ms is widely considered to be instantaneous. And it is instantaneous if you're coming from a world of 250ms. But people can in fact distinguish between 20ms and 100ms. A better definition of instantaneous, for the purpose of UI design, would be that 100ms is the threshold at which people start to take notice that something is NOT instantaneous. It's not enough to target sub-100ms. One has to target sub-50ms. Anything more than 50ms ruins the magic. |
