Holographic Assistant

A Holographic Assistant, also known as Holographic Guide, is a technology used by Black Mesa to replace live assistants in monitoring the employee's training.

Overview

 * Gina Cross and Miller are responsible for the training of scientists and security guards, respectively. When their work requires them to be elsewhere in the facility, they are replaced by their holographic counterparts. While Richard Keller, Isaac Kleiner and Colette Green also supervise Hazard Course training, they do not seem to have holographic counterparts.


 * Used in the Black Mesa's Hazard Course, the assistant directs scientists and security guards to the different hazards they might meet during their work at Black Mesa. Scientists are above all trained to the use of the HEV Suit during the standard Hazard Course, while security guards go through less dangerous tests, since they are only protected by their simple helmets and Kevlar vests, during the Black Mesa Hazard Course for Security Guard Training.


 * Additional scientists often monitor the trainings from nearby examination rooms.


 * Holography is also used by Black Mesa for sending messages, as seen by Adrian Shephard in Sector E.

Trivia

 * Gina's hologram model from Half-Life was reused in Blue Shift as Gina Cross delivering the Xen crystal sample into the elevator.
 * Holography is featured in many science fiction universes, such as Star Wars or Star Trek.
