Did you know that the first version of a barcode looked like a bullseye? This clever design was created by a man named Woodland. He had a great idea to help store workers scan items quickly and easily, no matter how the items were placed. Imagine you’re at the store, and the cashier is scanning your groceries. Sometimes the labels are upside down, sideways, or even perfectly straight. Woodland realized that if the barcode could be read from any direction, it would make things much easier.
Woodland wanted to base his barcode design on Morse code, which uses dots and dashes to represent letters and numbers. However, there was a problem. Just like how you need to read words in the right order, a Morse code design would need to be scanned in a specific way. If the barcode was upside down or sideways, it wouldn’t work.
To solve this problem, Woodland came up with a brilliant idea. He expanded the dots and dashes into circular lines, creating a bullseye pattern. This design allowed the barcode to be read from any angle, making it omnidirectional. It was like having a code that could be scanned in an infinite number of ways!
When Woodland looked at his sketch, he realized how important his invention could be. He shared his idea with his friend Bob Silver, and together they worked on bringing this innovative concept to life. The bullseye barcode was a big step forward in making shopping faster and more efficient.
Today, barcodes are everywhere, and they help us in many ways, from checking out at the grocery store to tracking packages. Woodland’s creative thinking and problem-solving skills led to a technology that has become a part of our everyday lives.
Imagine you are Norman Woodland and design your own version of a bullseye barcode. Use paper and markers to draw a circular barcode that can be read from any direction. Think about how you can incorporate different shapes and patterns to make it unique. Share your design with the class and explain how it could be used in a store.
Bring in a few items from home that have barcodes. In small groups, take turns scanning the items using a barcode scanner app on a smartphone. Try scanning the barcodes from different angles and positions. Discuss why the bullseye design was important for making barcodes easy to scan.
Learn the basics of Morse code and try to encode a simple message. Then, think about how you could represent the same message using a barcode. Compare the two methods and discuss the advantages and disadvantages of each. Which one do you think is more efficient for modern technology?
Research the history of barcodes and create a timeline that highlights key events and developments. Include Woodland’s bullseye design and other important milestones. Present your timeline to the class and discuss how barcodes have evolved over time.
Organize a scavenger hunt where you search for different types of barcodes in your school or community. Take pictures of the barcodes you find and note where you found them. Share your findings with the class and discuss the different uses of barcodes in everyday life.
The first early incarnation of a barcode was actually in a bullseye shape. Woodland had enough foresight to realize that when store checkers would swipe items over the sensor, they would probably do so in various orientations. Even if every label was fixed perfectly to, let’s say, a can of soup, it might be upside down, horizontal, or vertical when the checker tried to swipe it. This created a problem because he was going to base his code design off of Morse code, and like the letters in a word, a Morse code style design wouldn’t be able to read from any angle.
Woodland solved this problem by expanding the dots and dashes into circular lines, which would make it omnidirectional. In other words, it essentially copied that Morse-inspired code into an infinite number of orientations for the sensor. Looking down at his sketch and realizing the potential significance of his invention, Woodland relayed the idea back to Bob Silver.
