One or more devices capture a scene of real world, and process one or more image(s) which include distances to points on surfaces in the real world. The distances are used to automatically identify a set of surfaces in the real world. The one or more devices check whether a surface in the set is suitable for display of an element of information to be projected into the scene. On finding that a surface is suitable, a transfer function is automatically identified, followed by automatic application of the transfer function to the element of the information. A transformed element, which results from automatically applying the transfer function, is stored in a frame buffer coupled to a projector, at a specific position in the frame buffer identified during the check for suitability. When no surface is suitable, user input is obtained, followed by projection of information per user input.
