Relationship between the additional confirmation timing of (c) location number and the rate of passing through (e) target spot. Additional confirmation frequencies of (c) location number in the prescription area are increased in the order “single-type drug < double-type drug,” on both the left area (A) and right area (B). Likewise, the rates of the visual line passing through (e) target spot in the drug rack area are groups A (22.2%), B (36.1%), C (38.9%), and D (52.8%), and they are also in the order “single-type drug < double-type drug (group A < group B, group C < group D).” The former and the latter are used as the indicators for instances when a pharmacist cannot process (c) location number and pinpoint (e) target spot in a single confirmation, respectively
