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. This 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?
This device comes to us from Reddit, where they describe that “in Japan, some whiteboards are equipped with an eraser that scans and saves the text as you erase it so students can access it later.”
It is a very interesting idea, mainly to imagine its impact in 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, this is a draft that when we see it in action is slow and noisy.
Kyung Hee University students describe that this device does not leave dust when erasing, but that in many cases it is faster to erase directly by hand .
This is a device that is 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 so that notes can be copied later is not new, and there are several more modern designs that go into this direction.
This blackboard with an electronic eraser has gone viral these days, probably due to its combination of extravagant aesthetics, original idea and enormous potential to change the way we could 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.
