Product Design : Barcode detector
Location : Main entrance of IUJ Library (MLIC Building 2nd Floor)
Mistake Prevention : Stealing books from library or forgetting to check-out the books at
the loan counter
Two body-sized barcode detectors are installed just near the main entrance of IUJ Library (MLIC Building 2nd Floor). Whenever students leave the library, the detector will beep if it detects that there are some books from the library that have not been checked-out at the loan counter. Although the barcode detector’s main purpose is to prevent students from stealing the library books, sometimes students can forget to check-out the books from the loan counter. Thus, this detector serves a secondary purpose to remind those forgetful students.
About Pokayoke
Poka-yoke (ポカヨケ?) (IPA: [poka joke]) is a Japanese term that means "fail-safing", "Foolproof" or "mistake-proofing" — avoiding (yokeru) inadvertent errors (poka)) is a behavior-shaping constraint, or a method of preventing errors by putting limits on how an operation can be performed in order to force the correct completion of the operation. The concept was formalised, and the term adopted, by Shigeo Shingo as part of the Toyota Production System. Originally described as Baka-yoke, but as this means "fool-proofing" (or "idiot proofing") the name was changed to the milder Poka-yoke.
