Apparatus and method for recognition of patient activities
A medication confirmation method and apparatus. The method of an embodiment of the invention includes the steps of capturing one or more video sequences of a user administering medication via a medication administration apparatus, storing the captured one or more video sequences, and analyzing at least one of the stored video sequences to confirm that the user has properly administered the medication, and has properly positioned the medication administration apparatus.
1. A patient activity recognition apparatus, comprising:
a display;
an audio-video capture device;
a processor; and
a computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to perform operations comprising
causing the display to present at least one audio-video instruction instructing a user to follow one or more interactive instruction steps to properly position a medication administration apparatus relative to the user and administer a medication using the medication administration apparatus,
causing the audio-video capture device to capture a first audio-video sequence of the user, in a first administration of the medication, performing one or more medication administration actions in accordance with the one or more interactive instruction steps,
storing the captured first audio-video sequence,
determining, based on the first audio-video sequence and at least one other audio-video sequence of at least one other administration of the medication, a change in the user's physical actions between the first administration of the medication and the at least one other administration of the medication, and
determining, based on the change in the user's physical actions, a change in a medical status of the user.
2. The apparatus of claim 1 , wherein the change in the user's physical actions comprises a change in an extent to which hands of the user are shaking between the first audio-video sequence and the at least one other audio-video sequence.
3. The apparatus of claim 1 , wherein the medical status of the user comprises a mental status of the user.
4. The apparatus of claim 1 , wherein the medical status of the user comprises a physical status of the user.
5. The apparatus of claim 1 , further comprising a data transmission system, and wherein the operations comprise causing the data transmission system to transmit the first audio-video sequence to a remote location for analysis.
6. The apparatus of claim 5 , further comprising a data reception system operable to receive further analysis results from the remote location.
7. The apparatus of claim 1 , wherein the operations comprise receiving recorded audio of the user using the medication administration apparatus in response to the presented at least one audio-video instruction.
8. The apparatus of claim 7 , wherein the operations comprise analyzing the recorded audio to aid in analyzing a current use of the medication administration apparatus to determine a status of one or more behavioral markers.
9. The apparatus of claim 1 , wherein the at least one audio-video instruction is part of a training sequence.
10. A patient activity recognition method, comprising:
presenting, on a display associated with a local device, one or more audio-video instructions instructing a user to follow one or more interactive instruction steps to properly position a medication administration apparatus relative to the user and administer a medication using the medication administration apparatus;
capturing, using an audio-video capture device associated with the local device, a first audio-video sequence of the user, in a first administration of the medication, performing one or more medication administration actions in accordance with the presented one or more audio-video instructions;
storing the captured first audio-video sequence;
determining, based on the first audio-video sequence and at least one other audio-video sequence of at least one other administration of the medication, a change in the user's physical actions between the first administration of the medication and the at least one other administration of the medication; and
determining, based on the change in the user's physical actions, a change in a medical status of the user.
11. The method of claim 10 , wherein the change in the user's physical actions comprises a change in an extent to which hands of the user are shaking between the first audio-video sequence and the at least one other audio-video sequence.
12. The method of claim 10 , wherein the medical status of the user comprises a mental status of the user.
13. The method of claim 10 , wherein the medical status of the user comprises a physical status of the user.
14. The method of claim 10 , further comprising transmitting the first audio-video sequence to a remote location for analysis.
15. The method of claim 14 , further comprising receiving further analysis results from the remote location.
16. The method of claim 14 , further comprising notifying an administrator of a change in one or more behavioral markers, the change in the one or more behavioral markers being indicative of the change in the medical status of the user.
