We present a novel illumination method for Light-guided Holograms, by forming an array of holographic optical elements (HoCODA) in counter-position to the LED array, which collimates and deflects light from each LED to realize ideal propagation within the LGP. A prototype contactless hover touch-screen user-interface device using HoCODA is described.
