Claim 11:
12. A method of collecting dosage information from a medicament delivery device, the method comprising:
detecting, with at least two optical sensors, light intensity reflected from a plurality of regions of a medicament dosage indicator of the medicament delivery device, where the plurality of regions are present in respective detection areas of the at least two optical sensors;
detecting, with the at least two optical sensors, changes of light intensity as the plurality of regions pass through the respective detection areas of the at least two optical sensors;
determining, by a processor, a current medicament dosage programmed into the medicament delivery device based on a count of the changes of light intensity; and
determining, by the processor, whether the current medicament dosage is increasing or decreasing, based on an order in which the at least two optical sensors detect the changes of light intensity as the plurality of regions pass through the respective detection areas.
