KaviAR [Holo] is a great way to allow the digital visualization of a human presence but in a contextual way (in the middle of a physical environment). Thanks to KaviAR [Holo], we can now humanize a message because all of the body language (smile, attitude, gesture) supports the message. The hologram can be used in everyday life to deliver a powerful, rich and explicit message. It is also a means of signifying a human presence where it is only abstract and non-representative.
