  • Patent number: 8970476
    Abstract: Methods, apparatus, and computer readable medium for creating and/or editing images are disclosed. An electronic tablet device may include a display, touch sensor, a motion sensor, controller and speaker. The motion sensor may generate input signals indicative of a spatial movement of the electronic tablet device. The controller may receive the input signals and generate output signals that move a drawing tool across a canvas of the display based on the spatial movement of the electronic device. The output signals may further update the canvas to reflect an effect of moving the drawing tool across the canvas per the tilting movement.
