The Dhaka Times Desk Now a special pen has been invented to catch spelling mistakes. A company called Lernstift in Munich has developed a pen that vibrates to indicate wrong spelling!
According to online news media, the discovered pen used ordinary ink. It looks like ten other pens. However, it is equipped with a special type of motion sensor, a small battery and a WiFi chip. These will control the precise movement of the pen as well as detect misspellings and bad handwriting. After about a year and a half of research, the special technology pen was developed by Learnstift.
In this regard, the co-founder of Learnstift said that the pen has two parts called 'calligraphy' and 'orthography'. The pen will tremble only if the writing does not match the vocabulary. Then the writer will realize that his writing is wrong. Then the writer can easily revise it. Source: Internet
