My mum was an English teacher back in Nigeria and I learnt early enough from when she graded students scripts that spelling errors were good enough reasons to fail your English test or exam.Technology today might have taking a bold step to eradicate such reasons as a pen has been developed to detect spelling errors while writing.
The Lernstift pen packs motion sensors that analyze your chicken scratch you can use the pen with standard paper or simply write words in mid-air and a vibrating motor that buzzes when the pen detects errors. Future versions will sport a Wi-Fi connection to be leveraged by an open development platform that people can use to create specialized apps for the pen as it connects to various devices.
Doug Aamoth (Technology editor for TIME Magazine) mentions that the pen exists in 2 modes: Calligraphy and Orthography. Calligraphy mode senses "if a letter is written wrong or illegibly" according to the company, and then vibrates once to alert the user to the error. With the Orthography setting " the pen vibrates once for a misspelled word and twice to point out grammatical errors in a sentence". The pen simply alerts the user that an error has been identified; it is then up to the user to figure out the problem and correct it. It is said to be a teaching pen rather than a spell checker.
