How AR can make us feel more connected to the world

Technologist Galit Ariel believes that humanity's final frontier is the mind-blowing, space-bending technology known as augmented reality. Our bodies and minds are wired for rich physical interactions, and AR adds a digital layer directly onto or within our existing environment -- to transform our living rooms into lush jungles, for example. The possibilities for technologies to help us be more present and connected to the world are infinite as space itself. "Amazing journeys await us right here on planet Earth," Ariel says. "Bon voyage."
