3D Projector

Update: we now hear that Visa will run a campaign using that 3D display as part of its Olympics-themed “Go World” initiative.

CBS Outdoor today unveiled an HD 3D projection display in New York City's Grand Central Station (daily from 11:30am to 1:30pm, throughout February). This 3D display requires glasses, which will distributed to people. They say that 70,000 people pass by that spot each day. That's a lot of glasses!

The 3D ad campaigns will also be complemented with 3D dioramas placed throughout the Shuttle passageway. In fact they plan to use more than 100 pieces of 'client media elements' throughout the station. You won't be able to escape from those ads... 

The CBS has collaborated with N4D on this campaign.

Chinese researchers have created the largest 3D holographic display at 1.8 x 1.3 m². Their invention also includes a way to record and transmit the images. The use 64 digital cameras to capture a 3D object, and the large display uses 64 projectors to re-create the image.

Each projector emits its data onto a holographic functional display screen at various angles. By mirroring the image capture setup, the projectors can recreate the original 3D object. Since the magnification depends only on the ratio between the geometry sizes of projector and camera arrays, the screen size is not limited by the usual restraints experienced by holographic technology. In fact this method can be used to create 3D images in any size, and retain a high-quality image.

The team wants to commercialize this system, but are currently busy optimizing it and developing hardware and software solutions for various applications.

LG is introducing a new 3D projector: the CF3D. It has FullHD, 3D and a single-lens. It sports 3D auto picture calibration, a twin engine, two HDMI 1.3 sockets, 300 ANSI lumens and a single USB input.

Zalman Tech are already making 3D monitors (and are selling them together with Fuji Film) and polarizing filters for 3D displays. They are now seeking to expand that business. They have invested in Real Scope (a 3D content developer), and hold 11%, and they consider going into 3D film for projector and cameras.

Zalman are also looking to raise funds for facilities for producing larger polarizing films (they can currently make up-to 32" filters).

Sony is showing a set of 3D video production systems, which includes a camera, processor, monitors, projector, and more. Sony is also showing the "3D LED Wall", which is a 280" LED display (6.4m in width, 3.4m height). It can show both 2D and 3D video. The 'wall' is made from 70 LED displays. To view the 3D image you need polarizing glasses.

A team of scientists form the University of Tokyo have made a new touchable 3D holographic display. They are using their airborne ultrasound tactile display to create a sensation on the user's hand without any direct contact, and without interfering with the holographic display.

The touchable hologram's visual component is generated by projecting an image from an LCD projector onto a concave mirror. The ultrasound 'display' radiates airborne ultrasound, and produces high-fidelity pressure fields onto the user's hands, without the use of gloves or mechanical attachments. This is based on a nonlinear phenomenon of ultrasound: acoustic radiation pressure (when an object interrupts the propagation of ultrasound, a pressure field is exerted on the surface of the object). With an ultrasound transducer array, various patterns of pressure field are produced in 3D free space.

"The Airborne Ultrasound Tactile Display is guided by a "vision-based hand tracking system," the team explains, adding that "the tactile display exerts the radiation pressure on the user's hands when they 'touch' 3D virtual objects."
