A holographic HMI is described by which data and commands can be entered into computers and other electronic equipment. The holographic HMI involves no tangible physical contact between the human operator and the control elements of the HMIs because the input devices are holographic images of keys or other customarily touch-activated tangible input elements. Operator interaction with those holographic images is detected through electromagnetic means or other means, obviating the need for direct physical contact with any solid input object or surface. Such holographic HMIs comprise a hologram for generating a holographic image of a tangible input object of the tangible control mechanism for the electronic or electro-mechanical device. 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, generated by the hologram, of the tangible input object, 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.
