Abstract

This disclosure provides systems, methods and apparatus for processing, transmitting and displaying data received from an analyte sensor, such as a glucose sensor. The system may include a display device with at least one input device. In response to movement of or along the input device, the display device may change a glucose data output parameter and update an output of the display device using the changed output parameter.

Claims

1. A method for displaying glucose information to a user using a hand-held computing device, comprising:

displaying on a touch-sensitive display of a computing device a glucose chart including a trend line indicative of a glucose level of a host over a first time period;

displaying one or more event indicators on the chart, each event indicator positioned on the chart to indicate when an associated event occurred in time, wherein the associated event includes one or more of a calibration reference event, an insulin delivery event, a meal event, an activity event, a sleep event, or an illness event, and wherein displaying the one or more event indicators includes presenting an icon illustrative of the associated event proximate to the trend line of the glucose chart corresponding to the particular point in time; and

changing the time period of the chart from the first time period to a second, different time period, wherein changing the time period causes the event indicators to move on the chart so that the one or more event indicators continue to indicate when the associated event occurred in time.

2. The method of claim 1, wherein changing the time period comprises receiving user input indicative of a request to change the time period.

3. A method for displaying glucose information to a user using a hand-held computing device, comprising:

displaying on a touch-sensitive display of a computing device a glucose chart including a trend line indicative of a glucose level of a host over a first time period;

displaying one or more event indicators on the chart, each event indicator positioned on the chart to indicate when an associated event occurred in time, wherein the associated event includes one or more of a calibration reference event, an insulin delivery event, a meal event, an activity event, a sleep event, or an illness event, and wherein displaying the one or more event indicators includes presenting an icon illustrative of the associated event proximate to the trend line of the glucose chart corresponding to the particular point in time; and

adding an indicator to the chart in response to the computing device detecting a predefined user input.

4. The method of claim 3, wherein the predefined user input comprises touching a selected portion of the glucose chart.

5. A method for displaying glucose information to a user using a hand-held computing device, comprising:

displaying on a touch-sensitive display of a computing device a glucose chart including a trend line indicative of a glucose level of a host over a first time period;

displaying one or more event indicators on the chart, each event indicator positioned on the chart to indicate when an associated event occurred in time, wherein the associated event includes one or more of a calibration reference event, an insulin delivery event, a meal event, an activity event, a sleep event, or an illness event, and wherein displaying the one or more event indicators includes presenting an icon illustrative of the associated event proximate to the trend line of the glucose chart corresponding to the particular point in time; and

detecting a user selection of at least one of the one or more event indicators, and displaying further information on the display associated with the selected at least one event indicator.

6. The method of claim 5, wherein detecting the user selection comprises detecting a user-touch of the at least one event indicator on the display.

7. The method of claim 5, wherein the additional information is displayed in a pop-up window.
