Hitachi has a 3D projector that can project images onto real-world objects

Hitachi has demonstrated a 3D projector that can project images onto real-world objects. For the demo, a 3D image of a bird hatching was displayed on an artificial egg that was cradled in an artificial nest. But that’s not all. Viewers looking at the demo see the bird as a hologram, in that as the viewing angle changes, so too does the view of the image, just as it would were you to be watching a real bird. When a viewer looking at the image moves up or down or left or right, what they see changes to suit the viewing angle. And if that’s not enough, the projected image can be viewed by multiple people from multiple angles, and everyone sees it as they would were there an actual real-world object sitting there. Also, if the object is moved around a little, the system compensates for it automatically.

It is a full parallax 3D display. This technology has been shown before but the new system is improved.


Hitachi displays stereoscopic images in real space. They can be overlay stereoscopic views of real objects and can be seen by multiple people without glasses. [Stereoscopic Display Technology has developed]. This technology uses the video information from twenty-four projectors, stereoscopic display technology in real space using a combination of lenses and mirrors produce copies for half of the images. Stereoscopic images can be overlaid with a real object, and without using glasses, so you can see several people at the same time, digital signage is placed where a lot of people back and forth (digital signage ) You can view stereoscopic images that can be applied to more powerful and lower cost of various design validation, and training in skills such as manufacturing and health care can be expected to take advantage of a wide range of areas.



The system has a 60° horizontal and 30° vertical viewing angle and Hitachi reps report that it will have a resolution that is 1.6 times higher than anything shown before. There are reports that Sony is working on a similar system.

Hitachi believes that the projector could be used by design engineers, digital signature apps and perhaps as a training device in the manufacturing or medical arenas.
