Lernstift Smartpen Checks Your Spelling As You Write -

An ingenious prototype pen
developed by a German start-up is
promising to give our longhand
writing a similar sort of safety net.
Lernstift (German for “learning pen”)
is a digital pen with a difference,
carrying not only ink inside its
casing but also a tiny computer that
alerts users to spelling errors.
The AAA battery-powered Linux
computer includes a vibration
module and a patent pending non-
optical motion sensor which
recognizes specific movements and
shapes of letters and words.
The pen employs a menagerie of
sensors, including a gyroscope (for
measuring orientation),
accelerometer (for calculating
propulsion) and magnetometer (a
device that measures the strength
and direction of magnetic fields) —
all to calculate the pen’s 3-D
movements.
Lernstift recognizes all writing
movements, the company says,
written on paper or in the air and
built-in Wi-Fi allows scribblers to
connect with smartphones,
computers or other pens in a
network.
The pen was invented by software
developer and Lernstift founder Falk
Wolsky after seeing his wife’s
frustrations at watching their son
struggle with his homework.
Highlights of Smartpen:
* Prototype ink pen vibrates when
users make mistakes writing letters
and words
* Lernstift (German for “learning
pen”) created by Munich-based
start-up
* Pen has computer inside casing
with motion sensor which spots
spelling mistakes
* Kickstarter campaign launched to
help development and production
The first pens will initially recognize
only English and German spellings,
but other languages will follow.
Eventually, the company plan to
offer pencil, fountain and ballpoint
pen options with a launch price
between €120-150 ($160-200) falling
to under €50 ($60) depending on
how fast the company grow.
