Benefits of technology

This patented technology helps keep away from getting dirty with traditional methods like paper or pads used for writing purposes while still giving them their benefits. It does this through an automatic system where users only have to switch off when they want something written down instead of constantly worrying about how much things get mixed together during long hours at school.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving astigmatic vision for schoolchildren who have difficulty brushing their Blackboards due to excessive amounts of dirt or snowiness caused by them's clothing.
