Will you smile back when human holograms greet you at the airport?

How does the airport of the future preoccupy customers as they wait in never-ending lines? A handful of companies think the answer is an always-smiling, always-working human hologram. The virtual assistants are projected onto form-fitting cutouts that can almost look real, and several airports have already begun installing them to help passengers make their way through security. But according to Joanne McNeil at Domus, the hologram manufacturers aren't content to stop at airports. They want to enable Siri-like interactivity and bring the assistants to museums, retailers, and even doctors' offices to serve as friendly customer service agents. Domus has more on how such holograms are moving into the common workplace and what they might be used for in the future.
