Abstract

A system and method for monitoring the state of an individual. The method includes providing a stimulus to the individual, measuring a response to the provided stimulus, comparing the measured response to an expected response, and diagnosing one or more aspects of disease in accordance with the result of the comparison between the measured response and the expected response. The stimulus may be a predetermined test sequence, such as a visually displayed predetermined sequence of images, or may include observation of the physical response of the individual while performing one or more predetermined activities. Stored images or video of the individual responding to one or more test sequences may be stored in a lossy or lossless state, and thus security and de-identification may be provided to stored data. This stored data may also be de-identified in a manner to allow for the answering of the greatest number of future questions.

First claim

What is claimed is:

1 . A method for monitoring a state of an individual, the method comprising:
obtaining a video record of the individual performing a physical activity; de-identifying the video record, wherein de-identifying the video record comprises
identifying a subset of points to be extracted from the video record, the subset of points allowing for future analysis of the physical activity, and
storing the subset of points without storing the video record to inhibit re-identification of the individual in the video record;
measuring the physical activity as recorded by the stored subset of points; comparing the measured physical activity to an expected physical activity to obtain a comparison result; and determining one or more status categories of the individual based on the comparison result.

2 . The method of claim 1 , comprising storing non-visual information associated with the video record and selected from one or more sensor outputs.

3 . The method of claim 1 , comprising:
identifying a subset of sensors of a plurality of sensors applicable to recognize a particular status category of the individual; recording a second physical activity by the subset of sensors; and analyzing the recorded second physical activity to confirm a presence or absence of the particular status category.

4 . The method of claim 1 , comprising:
recording a second physical activity by a plurality of sensors; and analyzing the recorded second physical activity to determine a presence or absence of one or more possible recognized status categories.

5 . The method of claim 1 , wherein the subset of points comprises facial keypoints.

6 . The method of claim 1 , wherein the subset of points corresponds to one or more portions of a face of the individual.

7 . The method of claim 1 , comprising displaying, to a user, an interface by which the user is able to modify a number of points to be included in the subset of points.

8 . The method of claim 1 , comprising:
blurring a portion of the video record; and storing the blurred portion in association with the stored subset of points.

9 . A system for monitoring a state of an individual, comprising:
a video capture device; one or more processors; and a memory storing one or more non-transitory, computer-readable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
obtaining, from the video capture device, a video record of the individual performing a physical activity;
de-identifying the video record, wherein de-identifying the video record comprises
identifying a subset of points to be extracted from the video record, the subset of points allowing for future analysis of the physical activity, and

storing the subset of points without storing the video record to inhibit re-identification of the individual in the video record; measuring the physical activity as recorded by the stored subset of points; comparing the measured physical activity to an expected physical activity to obtain a comparison result; and
determining one or more status categories of the individual based on the comparison result.

10 . The system of claim 9 , wherein the operations comprise storing non-visual information associated with the video record and selected from one or more sensor outputs.

11 . The system of claim 9 , comprising a plurality of sensors, wherein the operations comprise:
identifying a subset of sensors of the plurality of sensors applicable to recognize a particular status category;
recording a second physical activity by the subset of sensors; and
analyzing the recorded second physical activity to confirm a presence or absence of the particular status category.

12 . The system of claim 9 , comprising a plurality of sensor, wherein the operations comprise:
recording a second physical activity by the plurality of sensors; and analyzing the recorded second physical activity to determine a presence or absence of one or more possible recognized status categories.

13 . The system of claim 9 , wherein the subset of points comprises facial keypoints.

14 . The system of claim 9 , wherein the subset of points corresponds to one or more portions of a face of the individual.

15 . The system of claim 9 , comprising a display, wherein the operations comprise displaying, to a user, by the display, an interface by which the user is able to modify a number of points to be included in the subset of points.

16 . The system of claim 9 , wherein the operations comprise:
blurring a portion of the video record; and storing the blurred portion in association with the stored subset of points.
