A holographic HMI allows data and commands to be entered into electronic equipment. The HMI involves no tangible physical contact between the human operator and the control elements because the input devices are holographic images of keys or other customarily touch-activated tangible input elements. Operator interaction is detected through electromagnetic means, obviating the need for direct physical contact with any solid input object or surface. Such HMIs generate a holographic image of a tangible input object of the tangible control mechanism. An illumination device illuminates the hologram to produce the holographic image. An actuation detection device detects the selection by the operator of a holographic image, and a signal generator receives the detection of the actuation detection device and provides an input signal to the electronic or electro-mechanical device thereby to produce the response. The hologram is affixed to a transparent or translucent material.

A method and a device for encoding and reconstructing computer-generated video holograms using a conventional LC display: it provides holographic reconstruction of three-dimensional scenes using electronically controllable pixel in a holographic array (3) with a conventional resolution, and is reasonably free from flickering and cross-talk. Reconstruction is in real time, and for both eyes at the same time, over a large viewing zone. The method takes advantage of an optical focusing means (2) in order to image vertically coherent light emitted by a line light source (1) into viewing windows (8R, 8L) after modulation by the pixel array (3). The holographic reconstruction (11) of the scene is rendered visible from viewing windows (8R, 8L) for both eyes of an observer by way of diffraction at the pixels. According to the invention, the controllable pixels are disposed in vertical pixel columns (15, 16), which encode separate holograms of the same scene for each of the viewer's eyes (R, L), where said holograms are one-dimensional in the vertical direction and horizontally interleaved. An image separation means (7) with separating elements arranged parallel to the pixel columns reveals the respective pixel columns (15, 15′ or 16, 16′) for one eye and covers them for the other eye.

Disclosed are a mobile terminal and a hologram controlling method thereof. Texts, moving images, contents, and so forth may be displayed as a hologram image, and the displayed hologram image may be variously controlled according to a user's touch. This may solve spatial limitations of a general mobile terminal, and may implement a holographic video call more effectively.
