Holographic greeters started to pop-up in airports like JFK in New York a couple of years ago. Now the technology is expanding to municipal buildings and private offices around the world. The town council of Brent in England recently installed a "virtual assistant" who appears to sitting behind a desk but is actually a projection who helps point people in the right direction. The hologram is programmed to answer a limited number of questions, and can tell visitors where the correct part of the building is to register births and deaths or apply for a marriage license or citizenship. Hopefully she will be able to also answer the most common question, "Where are the bathrooms?" Will we be seeing more virtual receptionists like this? As the technology improves, most definitely so.
