Abstract: A device comprising a display, a user interface configured to receive gesture input, and a processor is provided. The device is configured to electronically detect, with the user interface, at least one gesture input from the user in an approximately circular motion that traces a substantially closed curve without corners about a point on the user interface. The device is configured to display, on a portion of the display, a polygonal shaped chemical structure symbol representing a polygonal ring of carbon atoms in response to the detecting, the polygonal ring having a set number of vertices representing a set number of carbon atoms. A non-transient computer readable medium having instructions stored thereon that cause a device comprising a display, a user interface configured to receive gesture input, and a processor to perform a method is also provided.

Abstract: Gestures for creating chemical structure symbols representing rings of carbon atoms on a touch screen device include circular motions that cause a touch screen enabled device to display symbols representing chemical structures or related information in response to the gestures.

Abstract: Gestures for creating chemical structures on a touch screen device include circular motions, check marks, and swipes that cause a touch screen enabled device to display symbols representing chemical structures or related information in response to the gestures.
