1. A method for manipulating a 3D image, the method comprising the steps of:

  • detecting a multiple-finger linear gesture on a touchpad;

    generating a signal indicative of the multiple-finger linear gesture;

    determining a speed of the multiple-finger linear gesture on the touchpad; and

    rotating the 3D image after the multiple-finger linear gesture for a time period proportional to the speed of the multiple-finger linear gesture;

    wherein said rotating comprises rotating 3D the image around a first axis when the multiple-finger linear gesture includes a first number of fingers, and rotating the 3D image around a second axis orthogonal to the first axis when the multiple-finger linear gesture includes a second number of fingers different from the first number of fingers.
