a processor;

a sensor, wherein the sensor is configured to:

detect an article with two or more information sources within a predetermined distance of the sensor, wherein the information sources contain characteristic information of the article and the predetermined distance is a length of space between the article and the sensor, and

detect the characteristic information from at least one of the information sources;

a memory storing instructions that, when executed by the processor, cause the processor to:

receive predefined characteristic information,

select detected characteristic information from one of the information sources based on the detection from the two or more information sources, and

compare the selected detected characteristic information with the predefined characteristic information; and

an indicator configured to generate an alarm in response to the processor detecting that the selected detected characteristic information is greater than or less than the predefined characteristic information.

2. The wearable device of claim 1 , wherein the predefined characteristic information is received from a remote server.

3. The wearable device of claim 2 , further comprising an antenna configured to receive the predefined characteristic information transmitted from the remote server.

the article is a medicine container;

the predefined characteristic information comprises an identification of a medicine dosage prescribed to a user; and

the characteristic information comprises an identification of the dose of the article.

5. The wearable device of claim 1 , wherein the predefined characteristic information comprises an amount of one or more ingredients harmful to a user and the characteristic information comprises an amount of one or more ingredients of the article.

6. The wearable device of claim 1 , wherein the alarm is a haptic signal.

7. The wearable device of claim 1 , wherein the sensor comprises an imaging device.

8. The wearable device of claim 1 , wherein the sensor comprises at least one of a Quick Response Code reader, a barcode reader, a camera, or a Radio-frequency Identification (RFID) reader.

9. The wearable device of claim 1 , wherein at least one of the information sources comprises an RFID tag.

10. The wearable device of claim 1 , wherein at least one of the information sources comprises a label on the article.

17. The wearable device of claim 1 , wherein the article is a medicine container.

18. The wearable device of claim 1 , wherein the article is a food-product container.

19. A condition-responsive wearable device, comprising:

a processor;

two or more sensors of different types, wherein each sensor is configured to:

detect one or more information sources associated with an article within a predetermined distance of the sensor, wherein the information sources contain characteristic information of the article and the predetermined distance is a length of space between the article and the sensor, and

detect the characteristic information from at least one of the information sources;

a memory storing instructions that, when executed by the processor, cause the processor to:

receive predefined characteristic information,

select detected characteristic information from one of the information sources based on the detection from the two or more information sources, and

compare the selected detected characteristic information with the predefined characteristic information; and

an indicator configured to generate an alarm in response to the processor detecting that the selected detected characteristic information is greater than or less than the predefined characteristic information.

20. A non-transitory computer-readable medium storing a set of instructions that are executed by at least one processor to perform a method, the method comprising:

receiving characteristic information of an article detected by a plurality of sensors of a wearable device, each sensor detecting characteristic information from at least one information source with the article within a predetermined distance of the sensor, further wherein at least two information sources contain characteristic information of the article, and the predetermined distance is a length of space between the article and the sensor;

receiving predefined characteristic information;

selecting detected characteristic information from at least two of the information sources based on data from the two or more information sources;

comparing the selected detected characteristic information with the predefined characteristic information; and

detecting that the selected detected characteristic information is at least one of greater than or less than the predefined characteristic information.
