Claim 8:
9. A medicament delivery system comprising:
a medicament delivery device; and
a data collection device comprising:
at least two optical sensors, the at least two optical sensors being arranged to detect light from respective detection areas, and
a processor,
wherein the at least two optical sensors are configured to detect light intensity reflected from a plurality of regions of a medicament dose indicator of the medicament delivery device in the respective detection areas, and
wherein the processor is configured to
determine a current medicament dosage programmed into the medicament delivery device based on a count of detected changes of light intensity as the plurality of regions pass through the respective detection areas of the at least two optical sensors during programming of the current medicament dosage into the medicament delivery device, and
determine 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.
