Holocomm

"Holo Projectors are holographic communicators used to communicate with characters in remote locations. They can both play recorded messages ("Vmail") and transmit real-time conversations."

- Deus Ex: Invisible War description

Holocomms, also called holo projectors, are holographic communicators used to communicate with someone else having a holocomm in remote locations. They appear in Deus Ex, Deus Ex: Invisible War and Deus Ex: Human Revolution.

Characteristics
They can both play recorded messages called Vmail and transmit real-time conversations by holographic image of people. Each models (2027, 2052 and 2072) are different, diffusing a large holographic image in 2027 to evolved into a small holographic image and therefore a more portable device by 2072. Also in the 2072 model, if there is a Vmail waiting, a letter icon is shown on the holocomm.
