From The Guardian:
May the force be with you … the Princess Leia hologram in Star Wars. Similar technology could soon be available on smartphones
Scientists have created a glasses-free, 3D display that could mimic the famous hologram projection of Princess Leia in the original 1977 Star Wars film.
The display is small and light enough to work on mobile phones, and produces images that appear in 3D even when viewed from different angles, the scientists said.
To make the device, researchers at Hewlett-Packard Labs in Palo Alto, California, built a transparent screen with tiny light emitting diodes (LEDs) around the edges. Light rays sent towards the centre encounter pixels that steer the light out of the screen in different directions.
Through careful control of the light, the device sends slightly different images to each eye, which are combined in the brain into a 3D object.
