A software tool acquires data on the position of touches relative to controls on a particular window or dialog box using touch screen controls. Subjects or users log on and the time the bring a dialog box into focus is time stamped. The coordinates of each touch is recorded along with a time stamp of the touches. The test sessions are saved in a data file identifying the subject. The software tool is used by a User Interface designer to design controls for a touch screen application. The acquired data is played back graphically to the designer where each touch appears as a dot or like indication over laid over a representation of the dialog box to which it relates. The acquired data may be displayed in various ways including composite, realtime or in a single dialog box or a single touch. Previous touch data may be kept or discarded giving the UI designer many options of how to analyze the dat to determine optimum size and placement of controls. The software tool may be integrated to a Graphic User Interface (GUI) building package for various software platforms.
