Claims:WE CLAIM:

1. A method for determining drug intake by a subject (102) by monitoring gestures of the subject (102), the method comprising:
receiving, by a gesture monitoring system (101), a plurality of sensor data (201) from a registered device worn on a finger of both hands of a subject (102), wherein the plurality of sensor data (201) is sensed for a pre-defined time duration after providing an alert to the subject (102);
determining, by the gesture monitoring system (101), parameters from the plurality of sensor data (201), wherein the parameters comprises magnitude change, turn angle change, direction change and time difference between consecutive samples of the plurality of sensor data (201);
determining, by the gesture monitoring system (101), one or more events associated with the finger of both hands of the subject (102) by comparing the parameters with a pre-defined range of turn angle change, direction change and time difference;
correlating, by the gesture monitoring system (101), the one or more events of the finger of both the hands occurring at same time duration using predefined rules to identify one or more sequences of intermediate gestures; and
identifying, by the gesture monitoring system (101), one or more final gestures by correlating the one or more sequences of intermediate gestures using the pre-defined rules for determining drug intake by the subject (102).

2. The method as claimed in claim 1, wherein the alert is provided to the subject (102) by at least one of, through a registered communication device and through the registered device worn by the subject (102).

3. The method as claimed in claim 1, wherein the plurality of sensor data (201) received is filtered by the registered device.

4. The method as claimed in claim 1, wherein the plurality of sensor data (201) comprises coordinates details and orientation information associated with the finger of both hands of the subject (102).

5. The method as claimed in claim 1, wherein the one or more gestures for drug intake are pre-defined and stored in the gesture monitoring system (101).
6. The method as claimed in claim 1, wherein the one or more events comprises clockwise motion, anti-clockwise motion, angular motion, rotary motion, tilt movement and linear motion of both hands of the subject (102).

7. The method as claimed in claim 1, wherein the one or more final gestures comprises at least one of tearing a drug strip, sliding of drug from strip, taking the drug to mouth, placing the drug in the mouth, holding a container, tilting the container, opening and closing of a tap, holding a container of water and taking the container of water to mouth.

8. The method as claimed in claim 1, wherein the one or more sequences of intermediate gestures are identified based on an order of time duration.

9. A gesture monitoring system (101) for determining drug intake by a subject (102) by monitoring gestures of the subject (102), comprising:
a processor (115); and
a memory (113) communicatively coupled to the processor (115), wherein the memory (113) stores processor instructions, which, on execution, causes the processor (115) to:
receive a plurality of sensor data (201) from a registered device worn on a finger of both hands of a subject (102), wherein the plurality of sensor data (201) is sensed for a pre-defined time duration after providing an alert to the subject (102);
determine parameters from the plurality of sensor data (201), wherein the parameters comprise magnitude change, turn angle change, direction change and time difference between consecutive samples of the plurality of sensor data (201);
determine one or more events associated with the finger of both hands of the subject (102) by comparing the parameters with a pre-defined range of turn angle change, direction change and time difference;
correlate the one or more events of the finger of both the hands occurring at same time duration using predefined rules to identify one or more sequences of intermediate gestures; and
identify one or more final gestures by correlating the one or more sequences of intermediate gestures using the pre-defined rules for determining drug intake by the subject (102).

10. The gesture monitoring system (101), as claimed in claim 9, wherein the alert is provided to the subject (102) by at least one of, through a registered communication device and through the registered device worn by the subject (102).

11. The gesture monitoring system (101), as claimed in claim 9, wherein the plurality of sensor data (201) received is filtered by the registered device.

12. The gesture monitoring system (101), as claimed in claim 9, wherein the plurality of sensor data (201) comprises coordinates details and orientation information associated with the finger of both hands of the subject (102).

13. The gesture monitoring system (101), as claimed in claim 9, wherein the one or more gestures for drug intake are pre-defined and stored in the gesture monitoring system (101).

14. The gesture monitoring system (101), as claimed in claim 9, wherein the one or more events comprises clockwise motion, anti-clockwise motion, angular motion, rotary motion, tilt movement and linear motion of both hands of the subject (102).

15. The gesture monitoring system (101), as claimed in claim 9, wherein the one or more final gestures comprises at least one of tearing a drug strip, sliding of drug from strip, taking the drug to mouth, placing the drug in the mouth, holding a container, tilting the container, opening and closing of a tap, holding a container of water and taking the container of water to mouth.

16. The gesture monitoring system (101), as claimed in claim 9, wherein the one or more sequences of intermediate gestures are identified based on an order of time duration.
