The device including an image rendering module to scan the surface and to modify the image based on data obtained about a three dimensional nature of the surface. The device further including an optical image stabilization to adjust an alignment of the projector based on orientation data of the device, an electronic image stabilization module to shift the image within a projection area based on the orientation data and an image-tracking module to shift the image within the projection area based on changes in a relative positions of the image and a target.
