With Multi-Touch in OS X, you can use realistic gestures like swiping or pinching to switch between apps, navigate your content and get the most out of your desktop space.
The new Force Touch trackpad takes all the capabilities of Multi-Touch and adds force sensors that detect subtle differences in the amount of downward pressure you apply. This lets you have a deeper connection to your content, bringing more functionality to your fingertip. It also introduces haptic feedback to MacBook Pro — allowing you to not just see what’s happening on the screen, but to feel it.
