1. A method of detecting an orientation of a device (1) with respect to a direction of an acceleration force, comprising:

  • providing a device (1) having an optical device (10) comprising a first liquid (A) and a second liquid (B), said liquids (A;

    B) being immiscible, having different refractive indices and different densities and being in contact with each other via an interface (14); and

    a sensor (20) comprising a grid of pixels (22);

    sensing an image captured by the optical device (10) on a subset (24, 24

    ) of the grid of pixels (22); and

    calculating the orientation of the device (1) from the position of the subset (24, 24

    ) on the grid (22).
