Porsche description of the holographic display from the Electrek article:
"The upper layer integrates the driver’s display, and between the levels there is a holographic display that extends far into the passenger’s side. It shows individually selectable apps, which are stacked in virtual space and arranged by priority with a three-dimensional effect. The driver – or passenger – can use these apps to touch-free control primary functions such as media, navigation, climate control, contacts and vehicle. The desired symbol is activated by gestures that are detected by sensors. A grasping gesture means select, while pulling means control."
