Detecting medical status and cognitive impairment utilizing ambient data
Devices for determining the likelihood that a user of a primary monitoring device (“PMD”) has developed a medical condition, generally comprising sensors coupled to the PMD, wherein the PMD detects changes to sensor readings over time, and wherein the changes indicate a change in the likelihood that a user of the PMD has developed a medical condition. In some embodiments, motion sensors are operably coupled to the PMD, and the PMD monitors and saves data relating to characteristics of motion detected, which are used to determine whether there has been a change in a likelihood that a user is undergoing a medical event. In further embodiments, the PMD comprises cameras, and the PMD monitors and saves data relating to movement of a user's eyes, which is utilized to determine whether there has been a change to a likelihood that the user is currently undergoing a medical event.
1. A device for detecting changes to user interactions with a user interface, the device comprising:
one or more sensors operably coupled to a primary monitoring device (“PMD”);
the sensors comprising one or more of a touch screen, an input device, a gyroscopic sensor, an attitude sensor, a microphone, a camera and a motion sensor;
the PMD monitoring at least one of the sensors to detect user errors in interaction with the device;
the device querying one or more databases for database data and comparing an error rate with the database data, the database data containing one or more of measurements of error rates of other persons; past error rates of the current user; projected error rates based on physiological characteristics of the user, and/or any of the foregoing when read in an environment with comparable amount of ambient noise; and
the device identifying a level of difference between the database data and the error rate.
2. The device of claim 1 , wherein the error rate is compared to a second database, which database contains physiological changes and associated error rates (the “Association”).
3. The device of claim 2 , wherein the user is alerted to one or more of the physiological changes identified by the Association.
4. The device of claim 2 , wherein one or both of the error rate and the Association is provided to at least one of the user, a drug recovery program sponsor, and a health care provider.
5. The device of claim 2 , wherein one or both of the error rate and the Association is provided to a parent or a guardian of the user.
6. The device of claim 2 , wherein the user is alerted to one or more of the physiological changes identified by the Association when the physiological change is greater than one sigma deviation from normal when compared to one or more database measurement sources.
7. The device of claim 6 , wherein one or both of the error rate and the Association is provided to at least one of the user, a drug recovery program sponsor, and a health care provider.
8. The device of claim 1 , wherein error measurement is compared to data limited by one or more of location, ambient sound, or time of day.
9. A device for detecting changes to verbal cadence, the device comprising:
one or more sensors operably coupled to a primary monitoring device (“PMD”);
the sensors comprising one or more of a microphone, a gyroscopic or non-gyroscopic device capable of measuring movement caused by sound waves;
the PMD monitoring at least one of the sensors to detect a rhythmic and/or wave-like function (the “Cadence”) generated by a user's voice;
the device querying one or more databases for database data and comparing the Cadence with the database data, the database data containing one or more of measurements of other persons; past measurements of the current user; projected measurements based on physiological characteristics of the user; or measurements of other users; and
the device identifying a level of difference between the database data and the Cadence (the “Change”).
10. The device of claim 9 , wherein the Change is compared to a second database, which database contains physiological changes and associated measurements of a change to voice cadence (the “Second Association”).
11. The device of claim 9 , wherein the Change is determined only by comparison to database entries made in an environment with a comparable amount of ambient noise.
12. The device of claim 9 , wherein the user is alerted to one of more of the physiological changes identified by the Second Association.
13. The device of claim 9 , wherein one or both of the Second Association and the Change is provided to one or both of the user and a health care provider.
14. The device of claim 9 , wherein one or both of the Second Association and the Change is provided to a parent or guardian of the user.
15. The device of claim 9 , wherein the user's voice detected is compared to data regarding voice patterns to determine an identity of the speaker.
16. A device for detecting changes to a user's balance, comprising:
one or more motion sensors operably coupled to a PMD;
the PMD monitoring and saving data from the sensors, where such data is consistent with a fall or other loss of balance (an “Episode”);
the device determining whether a number of Episodes taking place over a set period of time exceed a threshold number;
where the threshold number is different for different levels of magnitude of Episodes.
17. The device of claim 16 , wherein the different levels of magnitude of Episodes requires at least a one sigma deviation from normal.
18. The device of claim 16 , wherein the different levels of magnitude of Episodes requires at least a two sigma deviation from normal.
