Abstract

Disclosed are computer-implemented techniques for analyzing physiology based on electrodermal activity. Initially, an individual'"'"'s autonomic data is captured into a computer system. The autonomic data provides information for evaluating the physiology of the individual. The autonomic data is captured through at least one sensor. Analysis, based on the autonomic data captured on the individual, is received from a web service. An output related to physiology is rendered based on the analysis which was received.

Claims

1. A computer-implemented method for analyzing physiology comprising:

capturing autonomic data on an individual into a computer system wherein the autonomic data provides information for evaluating physiology of the individual and wherein the autonomic data is captured through at least one sensor;

receiving analysis from a web service wherein the analysis is based on the autonomic data on the individual which was captured; and

rendering an output related to physiology based on the analysis which was received.

2. The method of claim 1 wherein the autonomic data includes electrodermal activity.

3. The method of claim 2 further comprising collecting accelerometer data on the individual.

4. The method of claim 3 further comprising determining contextual information based on one or more of skin temperature or the accelerometer data.

5. The method of claim 4 wherein the contextual information includes information for an activity that the individual is performing.

7. The method of claim 1 further comprising uploading the autonomic data to the web service.

8. The method of claim 7 wherein the uploading is accomplished using a mobile device.

10. The method of claim 1 further comprising collecting further data on one or more of heart rate, heart rate variability, accelerometer readings, respiration, or skin temperature.

11. The method of claim 1 wherein the sensor is attached to an appendage of the individual.

12. The method of claim 1 wherein the output, which is rendered, describes the physiology of the individual.

13. The method of claim 2 further comprising performing signature analysis on the electrodermal activity which was collected to identify a characteristic of the electrodermal activity that corresponds to a physiological condition.

14. The method of claim 13 wherein the signature analysis is based on the electrodermal activity as well as accelerometer data.

15. The method of claim 13 wherein the signature analysis is based on the electrodermal activity as well as one or more of heart rate, heart rate variability, respiration, or skin temperature.

16. The method of claim 13 further comprising inferring that the individual is experiencing a physiological condition based on observing the characteristic of the autonomic data.

17. The method of claim 16 wherein the inferring includes a probability factor that the person is experiencing the physiological condition.

18. The method of claim 16 wherein the physiological condition that is being experienced is one or more of a group including pain, anxiety, panic attack, epileptic seizure, sleep disorder, respiratory sleep problem, heart attack, depression, stress, reaction to medication, bipolar attack, distracted driving, concussion, stroke, autistic reaction, ADHD behavior, boredom, well being, being startled, being in a mood, having arthritis, cystic fibrosis, diabetes, addiction, eczema outbreak, fragile X syndrome reaction, obsessive-compulsive disorder, phobia, post-traumatic stress disorder, social anxiety disorder, or activation of sympathetic nervous system.

19. The method of claim 13 wherein the characteristic is used to provide a biomarker.

20. The method of claim 13 wherein the signature analysis includes rise time analysis of the electrodermal activity from onset of the physiological condition.

21. The method of claim 13 wherein the signature analysis includes fall time analysis of the electrodermal activity from a peak value following onset of the physiological condition.

22. The method of claim 13 wherein the signature analysis includes time duration for elevated electrodermal activity following onset of the physiological condition.

26. The method of claim 13 further comprising correlating the signature analysis to self-reporting.

27. The method of claim 2 wherein the electrodermal activity is collected with a plurality of sensors on the individual and the plurality of sensors includes at least one sensor on a left side of the individual and at least one sensor on a right side of the individual.

28. The method of claim 27 wherein the at least one sensor on the left side and the at least one sensor on the right side are used to identify a difference between dominant and non-dominant electrodermal activity which was collected.

29. The method of claim 1 wherein the physiological condition is analyzed as part of a clinical trial.

30. The method of claim 1 further comprising capturing autonomic data on a plurality of other people wherein the autonomic data is captured through one or more sensors.

35. The method of claim 30 further comprising one or more of detecting, clustering, and characterizing patterns in the autonomic data which was captured.

37. The method of claim 1 further comprising generating the analysis by the web service through cloud computation of at least one of the autonomic data, a subset of the autonomic data, or an initial analysis of the autonomic data.

40. The method of claim 13 further comprising, based on a signature, performing one or more of identifying when a treatment was not taken, determining treatment efficacy, analyzing time of day for treatment, identifying an adverse reaction to treatment, identifying side effects to treatment, determining treatment safety, or determining dose titration.
