RELATED CASES
This application is a continuation of application Ser. No. 11/682,218, filed Mar. 5, 2007, which claims priority to U.S. Provisional Patent Application Ser. No. 60/778,862, filed Mar. 3, 2006.


FIELD OF THE INVENTION
The present invention relates to user data presentation, and more particularly to interfaces for interacting with health data.
BACKGROUND
Electrical sensors, monitors, and devices built by an ever-changing group of manufacturers are constantly entering the market. Collectively, these devices will be referred to as SMDs (sensors, monitors, devices).
Users are increasingly looking to bring access to all of these SMDs to their daily routine. In the prior art, this remote access has been limited to historical information access such as databases or e-mails, while other SMD data is not remotely accessible.
In the prior art, SMDs functioned as individual devices, and collecting and accessing such data was difficult.

DETAILED DESCRIPTION
The method and apparatus described is a user interface to enable a user to interact with, and enter data into, an SMD Integration and Management Server (SIMS). The SIMS system offers a continuous always-on connection to the SMD data. The virtual user is a conceptual framework for viewing the comprehensive data available about a user on the SIMS. Virtual user can represent a single user (for example a user examining his or her own data), a platform for displaying health data from multiple users (for example for a family), or a platform for displaying health data to healthcare providers, in a context that enables them to easily determine when one or more of their patients may need attention. By presenting a virtual user, the viewer can become more pro-active about handling various issues. Furthermore, the virtual user enables the simple presentation of overall health status, showing the interaction between various individual health measurements.
FIG. 1 is a network diagram of one embodiment of the various elements of the system. The various SMDs 110 are coupled through various means to the SMD Integration and Management Server (SIMS) 150. They may be coupled directly, coupled through carrier network 130, coupled through the Internet 140, or they may be coupled through a data collector 115, which accumulates data from sensor 110, and sends it through network 120, 130, or 140 to SIMS 150. In another embodiment, SMDs may be independent devices which are not coupled to the SIMS 150. Rather, the SIMS 150 may receive data from a user 170 via a network 165. The network may be the Internet 140, a carrier network 130, or any other network. In one embodiment, the SIMS 150 includes a web server, which enables the user to access certain user interface pages, to enter, read, share, and otherwise interact with the collected data.
The data accumulated by SIMS 150 may be available to the user via a user mobile device 160, which accesses SIMS 150 through carrier network 155 or another network, or via another user device 170, such as a computer.
FIG. 2 is a block diagram illustrating one embodiment of a Virtual Management, Access, Control, Share (MACS) device on the SIMS server and its relationship to the actual SMD. The actual SMD 210 has an intermittent connection 215 to a server 220. The connection 215 may be through the Internet, through a carrier network, or through other means. The server 220 may be located in the same location as the real SMD 210.
The data receiving logic 225 receives the data from the actual SMD 210 or the user via an intermittent connection 215. The data is stored in historical database 230. The historical data is used by data mining engine 235, to present virtual MACS device 250 via a reliable always-on connection 260 to various recipients 275. In a healthcare setting for example, the recipients may include the user, healthcare providers, and family.
In one embodiment, data mining engine 235 may further interface with user alerts and rules 240 to generate notifications through intelligent notification engine 255. Intelligent notification engine 255 can send automatic notifications to designated recipients 275, when certain threshold or alert conditions are met. The threshold or alert conditions may include historical data, trend analysis, variance from charted trends, simple threshold, or any combination of the use of historical and current data from the actual SMD 210, or combination of SMDs. In one embodiment, the data mining engine 235 constantly monitors the database 230, to ensure that the alert rules and user thresholds 240 have not been triggered. Intelligent notification engine 255 can, in one embodiment, trigger a notification in an appropriate format to any designated recipient.
In one embodiment, in addition to the database 230, data from other relevant actual SMDs may be received as well via logic 245. For example, in health setting, in addition to the glucose meter, exercise data, medical reports, and/or other relevant conditions may be monitored. The threshold and alert rules 240 may utilize a combination of data from more than one real SMD to trigger a notification or command 270.
FIG. 3 is an exemplary health display for a family or other group of users. In one embodiment, each person in the family, or other group of users whose data is displayed in this format, has a picture, name, or other identifier. In one embodiment, if one of the user's health parameter values are outside acceptable parameters, or meet one or more alert triggers, that user's identifier is flagged 310 to visually indicate the problem. In one embodiment, a separate alert may also be sent to designated destinations. One embodiment of the alert mechanism is described in more detail in co-pending U.S. application Ser. No. 11/192,549, which is incorporated herein by reference.
In one embodiment, the family or other group health display may also include a health ticker 315, which includes heath data from each of the users within the display. In one embodiment, the health ticker utilizes color, font, images, icons, or other indicators to identify the user associated with each item on the ticker. In one embodiment, the system also uses color coding to flag any items that may be problematic (i.e. a significant increase in blood pressure, a significant drop in blood oxygen levels, negative trends, or other problems). Alternative means of tagging to highlight items that may be problematic, or indicate bad trends, may be used. In one embodiment, the user's icon/image or other indicator is concurrently highlighted or flagged, as shown in 310.
In one embodiment, the health display also enables a user to select a particular user 305, and/or a particular health parameter 325, to obtain additional information.
In one embodiment, the health parameter information may include identification of the SMD(s) 330 associated with the health parameter, as well as a graph 355 showing the health parameter's changes over time. In one embodiment, in addition to the changes over time, the display may include trend lines.
In one embodiment, the user can change the alert settings using a graphical interface. In one embodiment, the graphical interface overlays the actual data. One example of this is shown in FIG. 3. In the example in FIG. 3, when the user is adjusting the upper or lower thresholds 335, 345, 350 he or she can visually see how those thresholds relate to the actual historical health data. In one embodiment, the user may set multiple thresholds 335, 345, associated with different time units. For example, the blood glucose levels are generally different first thing in the morning, and in the early afternoon. Therefore, time-based thresholds 335, 345 may be set. By allowing the user to immediately see how these alert levels relate to their own historical data. This ensures, for example, that a user will not set a threshold which has historically been crossed without any health implications.
In one embodiment, the user may also set a data timer 340, which sets a period within which a measurement is expected (i.e. asking the user to measure their blood pressure every three hours at a minimum). The data timer 340, in one embodiment sends an alert or other notification if data is not received within the prescribed period of time. In one embodiment, for example, the “glucose testing” window may be between 11 a.m. and 2 p.m. to receive a post-lunch measurement. If no data is received within that window, an alert may be sent to the user, reminding them to eat lunch and/or take a measurement.
In one embodiment, each type of control, time control 360, lower threshold 370, upper threshold 375, change over time (x(t)) and acceleration (dx/dt) 380, may be controlled using drag and drop controls. Alternative methods of controlling these settings may be implemented.
Each of these thresholds may have one or more alerts associated with them. The alerts may be controlled from the health display using alert recipients list 365. In one embodiment, the alert recipients are controlled by a user. In another embodiment, the recipient's list 365 may be controlled by a parent, doctor, or other authorized individual or group.
In one embodiment, an alert log 390 provides a historical view of past alerts that were sent. In one embodiment, the alert log also includes who the alert was sent to. In one embodiment, each alert record in the alert log 390 may also include the resolution. For example, an alert log entry may read:

    
    
        Blood Glucose Reading not received in 3 hours, email to John
        Blood Glucose Reading not received in 4 hours, phone call to John, email to Cindy
        Blood Glucose Reading received, alert cleared.
    
    


In one embodiment, the health display may also include various settings, advice, frequently asked questions, etc. In one embodiment, the health display may be presented on a secure web page accessible by authorized users. In one embodiment, the health display may be a downloadable application, which obtains data from the central SIMS database via a secure connection. Alternative ways of accessing and presenting this data may be used. In one embodiment, the display may be changed depending on the available screen real-estate. In one embodiment, the data may be accessible, in a different form, via smaller devices.
FIG. 4 is an exemplary overview diagram of an individual's health data. On the left hand side 410 an outline of a user can be seen. The outline includes attached monitors and corresponding body-aspects. In one embodiment, the user may mouse over a particular body aspect, and have a pop-up window 430 display basic parameter data associated with that body-part. The user can also click a body-part, and open the frame on the right 420, which displays additional data. In one embodiment, the pop-up window 430 may further list any associated SMDs which have been used to obtain the data.
In one embodiment, alerts 440 associated with the selected device displayed on the right 420, are shown as well. In one embodiment, the alerts 440 may be modified by the user from this list.
In one embodiment, the user may further add or remove SMDs from the listing 450. In one embodiment, as a recognized SMD is selected, the corresponding body-parts are highlighted, and the reference data is added to the outline 420.
On the right hand side 420, a particular selected device and its associated data are shown. As can be seen, the individual's health data shown here is the data from a finger pulse oximeter, which measures blood oxygen saturation and heart rate. The data may include historical readings for the selected device, the last reading, or another method of displaying such data. In one embodiment, the user may set a display preference.
FIG. 5 is an exemplary health dashboard providing a compact view of health data to a user. In one embodiment, this is a small application which can show the overall health condition of one or more users. In one embodiment, this small application may be designed to be on a user's desktop. In one embodiment, the application may be implemented in Java, or a similar language. In one embodiment, the application may periodically pull data from the server. Alternatively, the data may be periodically pushed to the application by the server.
The “instant summary” 510 for each person shows a simple dial, which displays an overall health condition ranging from good, through acceptable, and to problem. Of course, more precise or smaller divisions may be displayed. In one embodiment, this data may be color coded, for example good being green, acceptable being yellow, and problem being red. Alternative methods of indicating ranging from labels to icons and other colors may be used.
As can be seen, the instant summary 510 for three of the four displays here are in the “neutral zone.” One instant summary 520 shows a user hovering in the “problem” zone. In that instance, in one embodiment, additional information is displayed. In this instance, the information displayed shows the measurement which is not in the acceptable range. Here, the measurement is blood glucose level (BG) which is at 180. In one embodiment, the display may also show the time the last measurement was taken. In one embodiment, the instant summary 510 concatenates all health parameters received from a user, to generate an “overall” view. In one embodiment, the indicator always shows a “problem” if any one of the health parameters reach an alert level. This may enable a simple display for a health professional, caregiver, or family member who wishes to monitor the health state of many users at the same time.
The user may, in one embodiment, by clicking on one of the instant summaries 510, open the main dashboard 530. The main dashboard in one embodiment similarly uses a dial-type interface to indicate readings. In one embodiment, this interface is designed to resemble a car's gauges, since that is an intuitive way of interacting with a large number of measurements. In one embodiment, the dials may display current measurements, average measurements, or range of measurements.
In one embodiment, from the main dashboard 530, the user may click on any of the dials to receive more in-depth data about the measurements associated with the particular health parameter.
FIG. 6 is an exemplary user interface page, including a summary of data. The selected tab 605 shows an overview of the health parameters associated with a particular user. These health parameters may include weight, activity/cardio, heart rate, blood pressure, blood glucose, cholesterol, blood oxygen levels, and various other parameters which may be measured by one or more SMDs. While the particular display shows a set of SMDs, the present system is designed to be able to display results data from any sensor, monitor, or device, whose data may be entered into the SIMS, whether manually or automatically.
In one embodiment, the user may further select any of the individual health parameters 615 to display them in more detail. One embodiment of this user interface feature is described in more detail in U.S. patent application Ser. No. 11/657,199, filed Jan. 23, 2007.
FIG. 7 is an exemplary health data display for a healthcare provider. As can be seen, the healthcare provider can visually see the health parameters of many individuals. The healthcare provider may be a doctor, a nurse, a home care provider, or another individual who is tasked with monitoring the health of multiple individuals.
In one embodiment, the primary interface for the healthcare provider is a results list 710, which displays all of the patients associated with the healthcare provider. In one embodiment, the healthcare provider can search among the users, using search tools 705.
In one embodiment, the particular users whose overall condition is not in the good or acceptable range are highlighted. In one embodiment, only those patients whose condition has changed for the worse are highlighted. In one embodiment, the user can select which users to highlight. In one embodiment, multiple types of highlighting may be done. For example, users whose next scheduled appointment is within a week (or other time period) may be highlighted. Users whose health parameters are problematic, or whose health parameters have changed for the worse may be highlighted. Users whose health parameters have improved, may also be highlighted.
In one embodiment, the search function enables the healthcare provider to also do searches based on any parameters, including scheduled visits, health parameters, changes in health parameters including first derivatives, trends, and any other relevant factors.
In one embodiment, the healthcare provider may select a particular user 715 from the results list 710. The more detailed records of the selected user may be displayed as user health information 725. This may enable the healthcare provider to see all of the relevant self-measured parameters for the patient. In one embodiment, the relevant measurements taken by a doctor, nurse, or other third party are highlighted or otherwise indicated. In one embodiment, if there is a significant discrepancy between self-measured data and third party data, this is highlighted as well. This enables the healthcare provider to visually see trends and easily identify problems.
The user information 720 may also provide additional data. In one embodiment, the user's health chart may also be available in this view. In one embodiment, all of the medications 750 taken by the user, including dosage, are also displayed. In one embodiment, the user's full medical record may be available in this format. In one embodiment, all medical data is stored securely and in compliance with applicable laws.
In one embodiment, the individual health parameters may be adjusted to view a different time span, or view the data in graphical or non-graphical format. For example, in the figure shown, the blood pressure is recorded for one day. An alternative display may provide a month view, with each day having a range-line showing the top & bottom readings.
In one embodiment, there is a simple mechanism for the healthcare provider to send an alert 790 or other notice to the individual user whose data has been received. For example, if the healthcare provider is concerned about something, he or she can send a notification to the user via the alert mechanisms that are part of the SIMS system. In one embodiment, the healthcare provider may select a “severity” for the alert, and the notification mechanism used by the alert may depend on severity. For example, to suggest to the user that a trend needs to be improved, and the user should walk more, a low severity alert indicated by an email may be sufficient. On the other hand, if the health data indicates a severe problem, the alert may be sent via voice message, or may be distributed to multiple parties.
In one embodiment, there is also a simple mechanism for the healthcare provider to schedule an appointment 780 with a user, if the user's medical data triggers the need for such an appointment.
Note that a healthcare provider may be a doctor, an insurance agent, a medical reviewer, or any other professional who legally has access to multiple user's health data in this format. The healthcare provider display is, of course, provided in a secure format, and designed to comply with HIPAA regulations.
FIG. 8 is an illustration of the relationship between the virtual user and the real user. The actual user 805 provides device data 810. Device data 810 may be provided automatically by various SMDs, or entered by the user 805.
The device data 810, in one embodiment is stored as health parameter data 825, in the SIMS database 830. In one embodiment, the SIMS database is behind a secure firewall. In one embodiment, the SIMS database 830 is only accessible to authorized users. In one embodiment, each user's device data 810 is stored in encrypted form, and only users who are authorized to view the device data 810 can decrypt it.
The virtual user 820 is a construct created by the SIMS system. The virtual user 820 is a way to measure the health status of the actual user 805, and get a snapshot of the overall health data. Health parameters 825 are associated with the virtual user as well.
In one embodiment, the database 830 is a virtual database. In other words, the data is not in a centralized database, but rather distributed in various ways. However, the individual user's virtual person 820 can be called up from the virtual database 830.
In one embodiment, an expert application 835 is used to evaluate the virtual user. The expert application 835 is used to evaluate the user's data. In one embodiment, the expert application 835 analyzes data from the database 830. In one embodiment, whenever new data is added to the database 830, the expert application 835 re-analyzes the complete data. In another embodiment, the database 830, in addition to storing raw device data 810, also stores analysis data. Thus, the expert application 835 uses the new device data 810, and previously stored & calculated analysis data to generate its evaluation.
In one embodiment, the expert application 835 can cause communications with the actual user 810. For example, if the user's health data indicates a problem, an alert 845 may be sent. Furthermore, the user may obtain reports 845, which provide summaries and useful data. In one embodiment, the user may also receive advice. For example, if an incipient problem is detected by expert system 835, instead of an actual alert some advice may be sent. The advice may range from “exercise more” to “drink less coffee in the morning,” or similar types of advice. In one embodiment, the actual user 805 may set preferences for the types of advice that will be sent.
In one embodiment, the expert application 835 may also communicate with care provider 840. In one embodiment, care provider 840 may also have access to the raw data in database 830. Care provider 840, in one embodiment, may also be able to generate alerts, reports, and advice 845 for the user.
The “virtual user” 820 enables a care provider, the user, and others to easily obtain current health parameter information, trends, problems, and analysis about a user, without requiring the user to be physically present. This provides a huge advantage since very few users are continuously connected to their health monitors and care providers.
FIG. 9 is one embodiment of a computer system that may be used with the present invention. It will be apparent to those of ordinary skill in the art, however that other alternative systems of various system architectures may also be used.
The data processing system illustrated in FIG. 9 includes a bus or other internal communication means 915 for communicating information, and a processor 910 coupled to the bus 915 for processing information. The system further comprises a random access memory (RAM) or other volatile storage device 950 (referred to as memory), coupled to bus 915 for storing information and instructions to be executed by processor 910. Main memory 950 also may be used for storing temporary variables or other intermediate information during execution of instructions by processor 910. The system also comprises a read only memory (ROM) and/or static storage device 920 coupled to bus 915 for storing static information and instructions for processor 910, and a data storage device 925 such as a magnetic disk or optical disk and its corresponding disk drive. Data storage device 925 is coupled to bus 915 for storing information and instructions.
The system may further be coupled to a display device 970, such as a cathode ray tube (CRT) or a liquid crystal display (LCD) coupled to bus 915 through bus 965 for displaying information to a computer user. An alphanumeric input device 975, including alphanumeric and other keys, may also be coupled to bus 915 through bus 965 for communicating information and command selections to processor 910. An additional user input device is cursor control device 980, such as a mouse, a trackball, stylus, or cursor direction keys coupled to bus 915 through bus 965 for communicating direction information and command selections to processor 910, and for controlling cursor movement on display device 970.
Another device, which may optionally be coupled to computer system 900, is a communication device 990 for accessing other nodes of a distributed system via a network. The communication device 990 may include any of a number of commercially available networking peripheral devices such as those used for coupling to an Ethernet, token ring, Internet, or wide area network. The communication device 990 may further be a null-modem connection, a wireless connection mechanism, or any other mechanism that provides connectivity between the computer system 900 and the outside world. Note that any or all of the components of this system illustrated in FIG. 9 and associated hardware may be used in various embodiments of the present invention.
It will be appreciated by those of ordinary skill in the art that any configuration of the system may be used for various purposes according to the particular implementation.

For example, the handheld device may be configured to contain only the bus 915, the processor 910, and memory 950 and/or 925. The present invention may also be embodied in a special purpose appliance including a subset of the computer hardware components described above. For example, the appliance may include a processor 910, a data storage device 925, a bus 915, and memory 950, and only rudimentary communications mechanisms, such as a small touch-screen that permits the user to communicate in a basic manner with the device. In general, the more special-purpose the device is, the fewer of the elements need be present for the device to function. In some devices, communications with the user may be through a touch-based screen, or similar mechanism.
It will be appreciated by those of ordinary skill in the art that any configuration of the system may be used for various purposes according to the particular implementation. The control logic or software implementing the present invention can be stored on any machine-readable medium locally or remotely accessible to processor 910. A machine-readable medium includes any mechanism for storing or transmitting information in a form readable by a machine (e.g. a computer). For example, a machine readable medium includes read-only memory (ROM), random access memory (RAM), magnetic disk storage media, optical storage media, flash memory devices, electrical, optical, acoustical or other forms of propagated signals (e.g. carrier waves, infrared signals, digital signals, etc.).
In the foregoing specification, the invention has been described with reference to specific exemplary embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention as set forth in the appended claims. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
