Trade Show Holograms recently exhibited their new dual sided large scale 3d hologram projector at the Global Petroleum trade show in Calgary Alberta Canada. The display creates a hologram effect floating in mid air in 3D. A video demonstration of this display can be seen here. https://www.youtube.com/watch?v=8BsPLhSKYcQ
The display is a dual sided exhibit which allows viewers to select and view holographic presentations on demand via the touch screen on one side while viewers on the opposing side can view entirely different presentations with out them interfering with each other.
The display features the new Ultra Bright Projection System which allows the images to remain bright and clear even in bright trade show environments. The 3D effect can be seen from far across the trade show floor.
