Abstract: A graphical user interface (GUI) presents to a clinician/user coded medical information in at least one logical hierarchy, and accepts selections of the presented information made by the user. An electronic medical record generator records user selections into an electronic medical record. The logical hierarchy may be organized, for example, by physiological system, or by type of examination. The GUI includes an image of a body, from which a user can select a body part for examination, examination method selection controls, and one or more sets of buttons optimized for a touchscreen. Each button has a bulbous portion and a narrower label portion. The bulbous portion is large enough to be easily contacted with the user's finger without the user's finger contacting an adjacent button. The narrow label portion protrudes from the bulbous portion and can contain a text label. The controls can thus be lined up alternately in opposite orientations so that they are tightly stacked.
