Abstract
A human machine interface (HMI) for an automotive vehicle comprises an instrument cluster and at least one head-up display for displaying information. The HMI includes at least one picture generation unit, each of which includes a laser for generating a modulated laser beam and a micro-electromechanical scanning minor arranged in the optical path of the laser beam for sweeping the laser beam over a diffuser in a two-dimensional Lissajous pattern. The HMI further comprises a central control unit that may be interfaced with a vehicle's on-board computer and/or another on-board device. A processor of the central control unit is configured to determine the pictures to be generated by the at least two picture generation units and to calculate, for each picture generation unit, the two-dimensional Lissajous pattern and the modulation of the at least one laser beam, the combination of which results in the respective picture to be displayed.
