Claims (14)

  1. A method comprising: receiving (580), at a smartwatch (199A) an alert representative of a glucose state of a host-patient coupled to a glucose sensor; detecting, at the smartwatch, a predetermined action indicative of a request to generate a glance view providing an indication of the glucose state of the host-patient; in response to the detecting, generating (582) and presenting (584), at the smartwatch, the glance view providing the indication of the glucose state of the host-patient; characterized in that in response to selection of a handoff icon on the smartwatch, sending by the smartwatch a message to a smartphone (112) that is wirelessly coupled to the smartwatch, the message indicating the glance view that is currently being viewed at the smartwatch; and receiving at the smartphone, from the smartwatch, the glance view and presenting at the smartphone the glance view, wherein the message comprises an index or indicator pointing to the glance view being viewed on the smartwatch that the user would like to view at the smartphone, and wherein the smartphone requests the glance view from the smartwatch based on the index.
  2. The method of Claim 1, wherein the alert is received via a low power radio access transceiver at the smartwatch.
  3. The method of Claims 1-2, wherein the alert is received from a receiver wirelessly coupled to the glucose sensor via transmitter sensor electronics.
  4. The method of Claim 3 wherein the receiver includes a continuous blood glucose application configured to interact with the smartwatch.
  5. The method of any one of Claims 1-4, wherein the alert is received from a remote server.
  6. The method of any one of Claims 1-5, wherein the detecting of the predetermined action triggers the smartwatch to replace a home screen and/or a default user interface view with the glance view.
  7. The method of any one of Claims 1-6, further comprising: triggering, at the smartwatch and in response to the detecting, a feedback comprising a haptic indicator, an audio indicator, and/or a visual indicator.
  8. The method of any one of Claims 1-7, wherein the predetermined action comprises a detection of a certain wrist movement.
  9. The method of any one of Claims 1-8, wherein the predetermined action comprises a detection of a certain eye movement of a wearer of the smartwatch.
  10. The method of any one of Claims 1-9, further comprising: detecting a swipe pattern; mapping the detected swipe pattern to at least one of a plurality of glance views, each of which is mapped to a different swipe pattern; and presenting, based on the detected swipe pattern, the at least one glance view.
  11. The method of any one of Claims 1-10, further comprising: mapping the glucose state to at least one of a plurality of glance views, each of which is mapped to a different glucose state; and presenting, based on the glucose state, the at least one glance view.
  12. The method of any one of Claims 1-11, further comprising: determining a role of a wearer of the smartwatch; mapping the role of the wearer to at least one of a plurality of glance views, each of which is mapped to a different role; and presenting, based on the determined role, the at least one glance view.
  13. The method of any one of Claims 1-12, further comprising: presenting a notification bar in the glance view in response to the alert; and detecting a user input to view the notification bar.
  14. The method of Claim 13, wherein the notification bar includes at least one actionable selection that displays a map, displays a glucose trend chart, acknowledges the alert, or dismisses the alert.

Description

FIELD The present disclosure generally relates to continuous glucose monitoring. BACKGROUND Diabetes mellitus is a disorder in which the pancreas cannot create sufficient insulin. In a diabetic state, a person suffering from high blood sugar may experience an array of physiological side effects associated with the deterioration of small blood vessels. These side effects may include, for example, kidney failure, skin ulcers, bleeding into the vitreous of the eye, and the like. A hypoglycemic reaction, such as a low blood sugar event, may be induced by an inadvertent overdose of insulin, or after a normal dose of insulin or glucose-lowering agent. In a severe hypoglycemic reaction, there may be a high risk for headache, seizure, loss of consciousness, and coma. A diabetic person may carry a self-monitoring blood glucose (SMBG) monitor which typically requires the user to prick his or her finger to measure his or her glucose levels. Given the inconvenience associated with traditional finger pricking methods, it is unlikely that a diabetic will take a timely SMBG measurements and, consequently, may be unaware whether his or her blood glucose value is indicative of a dangerous situation. Consequently, a variety of non-invasive, transdermal (e.g., transcutaneous) and/or implantable electrochemical sensors are being developed for detecting and/or quantifying blood glucose values. These devices generally transmit raw or minimally processed data for subsequent analysis at a remote device. The remote device may have a display that presents information to a user hosting the sensor. In some systems, a patient may check his or her glucose level on a hand held computing device. There are challenges to presenting this information discreetly and reliably. US 2015/0164390 A1 discloses "zero-click" veiwing of sensor data without any user input. A display with sensor data may be "always on," and may enable discrete viewing of sensor data without significant user hassle. Also, a system may be configured to display only current data, and/or to display the most current data for only a set interval. Also, one device in a continuous analyte monitoring system may be designated as a primary device, or hub, for receiving sensor data, and may control the flow of information and/or alerts to other devices in the system. Sensor data and/or alerts may be sent to a hierarchy of devices and/or persons in a designated order. SUMMARY According to the present invention, there is provided a method as set out in claim 1. Optional features are set out in the dependent claims.
