This project was a collaboration between me and my school's librarian. She recently had updated the library with a new scanner, which was resulting in an increase in library books being taken without being properly checked out. This was because the scanner required a book to be placed a very specific distance away from the scanner sensor, which was placed in an unclear location under its enclosure.
To combat this problem, I developed an acrylic bumper that attaches to the bottom of the scanner (as seen in the below photo). The bumper's bottom edge is the designed to be the precise distance away from the sensor where the scanner reads a barcode. Additionally, I designed a small, laser cut icon that indicates to users to scan the book by pushing it under the bumper. This symbol was intentionally etched onto the backside of the plastic so that it illuminates with the light of the sensor.
