Gujarat chief minister Narendra Modi will be the first Indian politician to use the latest 3D holographic projection technology - used by rock stars, including Madonna - during his campaign for the assembly polls in the state next month.

BJP sources here said Modi has roped in a Dubai-based firm to provide the technology, commonly known as Eyeliner, for Rs. 100 crore, which the state unit of the BJP will pay for.

Sources said that cost of five event setups using the technology is about $1 million (Rs 5.5 crore). The cost involves hiring a satellite for live transmission of speeches, audio systems, light, stages and projectors.

Modi's virtual campaign will be launched in Ahmedabad, Rajkot, Surat and Vadodara on November 18 when he will address gatherings from specially erected stages in four cities simultaneously.

After this, Modi plans to use the Eyeliner system to cover as many constituencies as he can and reduce his travelling which gets hectic at election time.

"3D technology is different from traditional video-conferencing. A special type of stage will be erected to project Modi ji's image at the venue of the gathering in such a way that people in the audience feel he is speaking before them," Gujarat BJP leader Purushottam Rupala said.
