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 computerized method for displaying glucose information on a display device of a glucose monitoring system, the method comprising:

(a) receiving glucose data measured by a glucose sensor;

(b) displaying glucose data in a first display mode in a portrait orientation on a display, the first display mode including a glucose trend line indicative of a glucose level of a host over a time period, the first display mode including at least one event indicator positioned proximate to the glucose trend line at a time when an associated event occurred, wherein the at least one event indicator includes an icon illustrative of the associated event;

(c) receiving user input indicating a change of display mode; and

(d) displaying glucose data in a second display mode in a landscape orientation on the display,

(e) wherein in the first display mode, the displayed glucose data is entirely displayed within a first area of the display and covers a first date range, and wherein in the second display mode, the displayed glucose data covers a second area of the display larger than the first area and a second date range longer than the first date range.

2. The method of claim 1, wherein the receiving glucose data includes receiving glucose data from a continuous glucose monitor.

3. The method of claim 1, wherein the portrait orientation is configured to allow a user to understand their current glucose situation at a glance, whereas the landscape orientation is configured to allow a user to view a more detailed and/or retrospective analysis.

4. The method of claim 1, wherein in the first display mode a comparatively lower resolution glucose trace is displayed and in the second display mode a comparatively higher resolution glucose trace is displayed.

5. The method of claim 4, wherein in the first display mode a numerical indicator of a current glucose value is displayed along with the glucose trace.

6. The method of claim 1, wherein in the portrait orientation a trend indicator and a numerical indicator of a current glucose value is displayed, whereas neither the trend indicator nor the numerical indicator are displayed in the landscape orientation.

7. The method of claim 1, further comprising displaying one or more event tags corresponding to event information.

8. The method of claim 7, wherein the event tags correspond to meal events, exercise events, or insulin delivery events.

9. The method of claim 7, further comprising, upon selection of an event tag by a user, displaying additional information about the event.

10. The method of claim 9, wherein the additional information about the event is displayed on a window that covers a portion of the display or that covers all of the display.

11. The method of claim 9, further comprising, in either the first display mode or the second display mode, or both, displaying a line indicating a current time on the displayed glucose data.

12. The method of claim 9, further comprising, in either the first display mode or the second display mode, or both, displaying numerical values adjacent at least one peak or valley in the glucose data, the numerical value indicating the glucose value at the respective peak or valley.

13. The method of claim 9, wherein the receiving user input includes receiving user input from a user interface.

14. The method of claim 13, wherein the received user input is a tap, double tap, pinch motion, spread motion, or button depression.

15. The method of claim 9, wherein the user input is received from a spatial sensor, a velocity sensor, or an accelerometer.

16. The method of claim 15, wherein the user input is received from a gyroscope or proximity sensor.

17. The method of claim 9, wherein the displayed data in the first or second display mode includes a prediction of future glucose levels.

18. The method of claim 9, further comprising overlaying additional information on the display, in the second display mode, in response to a first predetermined input by a user.

19. The method of claim 18, wherein the first predefined input includes moving a receiver in a predefined direction or pattern, the receiver including one or more accelerometers.

20. The method of claim 18, wherein the additional information is removed in response to a second predefined input by the user or after a predetermined time.

21. The method of claim 18, wherein the additional information includes historical data.

22. The method of claim 9, further comprising adjusting a time period of the displayed glucose data based on position data from a spatial sensor, such that a displayed date range changes as the display device is moved.

23. The method of claim 22, wherein the spatial sensor is selected from the group consisting of:

a gyroscope, a proximity sensor, a velocity sensor, or an accelerometer.

24. The method of claim 23, further comprising receiving a lock command from a user interface, wherein following receipt of the lock command, the displayed date range does not change as the display device is moved.

25. A non-transitory computer readable medium, comprising instructions for causing a computing environment to perform the method of claim 1.

26. A method of displaying glucose data according to user input, comprising:

(a) receiving glucose data in a continuous glucose monitor;

(b) receiving first orientation data from an accelerometer;

(c) displaying an indication of the received glucose data in a first display mode in a portrait orientation on a display, the first display mode based at least in part on the first orientation data, the first display mode including a portrait orientation, the first display mode including a glucose trend line indicative of a glucose level of a host over a time period, the first display mode including at least one event indicator positioned proximate to the glucose trend line at a time when an associated event occurred, wherein the at least one event indicator includes an icon illustrative of the associated event;

(d) receiving second orientation data from the accelerometer;

(e) transitioning to a second display mode and displaying an indication of the received glucose data in the second display mode in a landscape orientation on the display, the second display mode based at least in part on the second orientation data, the second display mode including a landscape orientation,

(f) wherein in the first display mode, the displayed glucose data is entirely displayed within a first area of the display and covers a first date range, and wherein in the second display mode, the displayed glucose data covers a second area of the display larger than the first area and a second date range longer than the first date range.

27. The method of claim 26, wherein data from the accelerometer allows the display to detect movement of the display as controlled by a user and is configured to change a date range displayed on the display based on how the user physically moves the display.

28. A non-transitory computer readable medium, comprising instructions for causing a computing environment to perform the method of claim 26.
