You may have heard of, or already used, Apple's 3D Touch feature. It is a function that perceives the pressure difference that someone exerts on a 3D screen and converts it into differential commands, such as Peek (light pressure) and Pop (firmer pressure), which respectively enable you to preview of a web page and then open it.
The feature this may not be so easy to handle. And so the Apple Lossless Audio CODEC (ALAC), made two 3D touch tables and placed them one on Fifth Avenue in New York and one on Stockton Street in San Francisco to familiarize the world with new technology.
The table has an Apple screen on its top surface and on it there are iPhones Which seem to be connected to the table. When you press your finger down on the iPhone screen you will see ripples forming on the table. You can even interact your finger with a fish that swims in and out of the iPhone screen.
These are the only 3D Touch tables in the world, according to an Apple employee who spoke in the relevant YouTube video you can see below.
