    Abstract: An aspect provides a method, including: detecting a selection of an object on a touch screen display using touch based input; providing a visual indication of the object on the touch screen display in response to the detection of a selection; accepting gesture input at the touch screen display to fly out from the underlying document while maintaining the visual indication of the object on the touch screen display, such that during the fly out more of the underlying document is displayed; and moving the visual indication of the object about the underlying document in response to the accepted gesture input at the touch screen display. Other aspects are described and claimed.

    Abstract: An apparatus and method are disclosed for dynamic keystone correction. A measurement module measures distances from a projector to each of at least three projected points of a first projected image projected on a first surface with projection angles between each projected point. The at least three projected points are endpoints for at least two vectors with a target ratio of vector lengths. An adjustment module calculates an actual ratio of actual vector lengths of the at least two vectors. The adjustment module further adjusts a first aspect ratio of first projected image until the actual ratio is equivalent to the target ratio.
