Whiteboards equipped with an electronic scanner that erases what is written and saves the notes to copy them later

It doesn’t have a modern design and there are many doubts about how it works, but sometimes we get such flashy devices that we can’t help but share them with you. It is the case of this blackboard equipped with an electronic scanner that moves along the board and erases what is written.

As soon as we see the image, many questions arise. Wouldn’t a white board be easier if we want to erase? Why should a whiteboard eraser be so big and heavy? How does the scanner work? Wouldn’t it be easier to just take a photo?

Another fascinating example of Asian technology

This device comes to us from Redditwhere they describe that “in Japan, some whiteboards are equipped with an eraser that scans and saves the text as you delete it so students can access it later.

It is a very interesting idea, mainly because Imagine its impact on the classes. In Europe, many schools have been using digital whiteboards for years, capable of displaying, erasing and synchronizing their content with the students’ computers. In this case, we are faced with a more rudimentary system but just as striking.

Although multiple users claim that there are these types of scanners in Japan, we only have evidence of their existence through several university students in Seoul, South Korea. Unfortunately, we are dealing with a draft that when we see it in action it’s slow and loud.

Students at Kyung Hee University describe this device as leaves no dust when erasing, but in many cases it is faster to erase directly by hand.

It is a device that has more than 10 years old; which explains its retro design and the fact that in this case it does not store the saved writing, it just deletes it. The idea of ​​scanners capable of saving what they erase in order to be able to copy the notes later is not new and there are several more modern designs that go in this direction.

This electronic eraser board has gone viral these days, surely for that combination of extravagant aesthetics, original idea and enormous potential to change the way we might have attended in class. Let us know in the comments what you think of this device and to what extent it would be interesting to have a modern equivalent.
