Abstract

A handheld display device for processing continuous sensor data has a communication interface, a graphical user interface having a gesture recognition component, a processor and a memory. The processor continuously receives time dependent sensor data, carbohydrate data, event data, and insulin data. The event data is indicative of a physical state of the subject. The processor determines a sensor data scaling factor, a carbohydrate data scaling factor and an insulin data scaling factor. The processor controls the graphical user interface to render a plot having single time, analyte concentration, carbohydrate amount, and insulin delivery amount axes. The analyte concentration axis is rendered on a first side of the plot and carbohydrate amount and insulin delivery amount axes are rendered on an opposite side of the plot, according to the scaling factors. The graphical user interface can be controlled with single and/or double finger gestures to magnify, shrink or shift axes.
