Election Campaigning uses 3D Holographic Projection Technology

From web sites, SMS, twitters, blogs, and Facebook, the Indian election campaigning has become more hi-tech. Gujarat Chief Minister Narendra Modi has utilised 3 D holographic projections to appear in front of audiences in different places in the state. 

After success of 3D interaction across 4 cities, Shri Modi to address people across 26 places in 15 districts using 3D projection technology, Interaction to take place across places in Saurashtra and South Gujarat.
The state-of-art technology used offers the audience/viewers a feel that the person is there real and even enables them to interact with the projected ‘virtual’ person as if interacting with actual person, eliminating the need of wearing 3D glasses.

What is 3D Holographic Projection Technology :

This is entirely a Latest and vary unique “Hi‐Definition Projection Technology” in which a person is Captured in 3‐dimentional Aspect with a Sp. Hi‐Definition Camera on a specially built Stage and Projected  “As Is “ at  various Distant Locations “At –A – Time”. Viewers at the other end will feel the presence of REAL Person in front of them and also interact with the projected ‘Virtual” person, without wearing any kind of 3D glasses, as they interact with ‘Actual Person’.

How 3D Holographic Projection Technology works:
Holography is a technique that enables a light field, which is generally the product of a light source scattered off objects, to be recorded and later reconstructed when the original light field is no longer present, due to the absence of the original objects.

Holography can be thought of as somewhat similar to sound recording, whereby a sound field created by vibrating matter like musical instruments or vocal cords, is encoded in such a way that it can be reproduced later, without the presence of the original vibrating matter.

A clever reimagining of the Pepper’s Ghost technique lets your magic happen. It starts with the patented foil, completely invisible to the naked eye. Rig it at 45° across the stage and then bounce content off a projector screen. This is then reflected upwards, reflects off the foil and gives the impression of a real 3D volumetric image on stage. With some clever lighting and stage dressing, and the result is the most stunning visual medium seen.
