Question
Dear Prof Scott

http://en.wikipedia.org/wiki/Seven-segment_display
http://www.maximintegrated.com/en/app-notes/index.mvp/id/1883
http://www.engineersgarage.com/electronic-components/7-segment-display

Is it possible to display content in different languages viz german, french, japanese, french, spanish, dutch, chinese etc using 7 segment led display other than english content in
products ?.

Products Examples : Weighing machine, Treadmill Machine, Steppers, Electronic meters etc

Will there be limitations in having a 7 segment led display for producing these products having 7 segment led display other than english content ?.

For example : Enter weight in Kg - This is english content
display in treadmill displayed in 7 segment LED Display.

Now can we have Treadmill products sold in different countries where the native language is spoken, for example In Japan Japanese, In China - Chinese etc having the equivalent of Enter weight in Kg in other languages viz Japanese, German, French, Italian etc displayed in 7 segment LED Display.

i.e. 7 segment Led display should be able to display multilingual characters other than english content.

Can there be limitations to 7 segment led display in displaying
different languages characters ?.

Awaiting your reply,

Thanks & Regards,
Prashant S Akerkar

Answer
In many other languages, the way the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 are written is done in a much more complicated fashion.  This can be seen in http://www.omniglot.com/language/numerals.htm

From here, it can be seen that in many countries, numbers are very different and would require a different sort of style than the our LED display.  Ge'ez (Ethiopian), Kannada, Tamil, and Urdu, for example, look really different.  Even something known, like Roman, would be difficult to put on a screen.  That was one of my computer projects was writing a C-program to take an American number and output it in Roman numerals.  Special attention needs to be paid attention to numbers with a 4 or 9 in them, for when 1 is I, 2 is II, 3 is III, 5 is V, 12 is XII, 53 is LIII, 81 is LXXXI, numbers that have a 4 or 9 are different.  For example, 4 is IV, 40 is XL, and 400 is CD.  The digit 9 gets even more complicated.  A simple 9 is IX, 19 is XIX, 29 is XXIX, 49 is IL, 90 is XC, 95 is VC, 99 is IC, 990 is XM, but there are some that really get tricky.  For example, start counting 38, 39, and 40.  That would be XXXVIII, XXXIX, and LX.  As can be seen, 38 is far different than 39, but an even bigger jump is made form 39 to 40.

Just as in English, when we see, '1', we think 1.
To see what foreigners say, see en.wikipedia.org/wiki/List_of_numbers_in_various_languages

From this, it is not possible at all to display numbers in many countries.

However, numbers written in English can be found and
are understood by many throughout the world.

Expertise

I can answer any question in general math, arithetic, discret math, algebra, box problems, geometry, filling a tank with water, trigonometry, pre-calculus, linear algebra, complex mathematics, probability, statistics, and most of anything else that relates to math. I can also say that I broke 5 minutes for a mile, which is over 12 mph, but is that relevant?

Experience

Experience in the area; I have tutored people in the above areas of mathematics for over two years in AllExperts.com. I have tutored people here and there in mathematics since before I received a BS degree back in 1984. In just two more years, I received an MS degree as well, but more on that later. I tutored at OSU in the math center for all six years I was there. Most students offering assistance were juniors, seniors, or graduate students. I was allowed to tutor as a freshman. I tutored at Mathnasium for well over a year. I worked at The Boeing Company for over 5 years. I received an MS degreee in Mathematics from Oregon State Univeristy. The classes I took were over 100 hours of upper division credits in mathematical courses such as calculus, statistics, probabilty, linear algrebra, powers, linear regression, matrices, and more. I graduated with honors in both my BS and MS degrees. Past/Present Clients: College Students at Oregon State University, various math people since college, over 7,500 people on the PC from the US and rest the world.

Publications
My master's paper was published in the OSU journal. The subject of it was Numerical Analysis used in shock waves and rarefaction fans. It dealt with discontinuities that arose over time. They were solved using the Leap Frog method. That method was used and improvements of it were shown. The improvements were by Enquist-Osher, Godunov, and Lax-Wendroff.

Education/Credentials
Master of Science at OSU with high honors in mathematics. Bachelor of Science at OSU with high honors in mathematical sciences. This degree involved mathematics, statistics, and computer science. I also took sophmore level physics and chemistry while I was attending college. On the side I took raquetball, but that's still not relevant.

Awards and Honors
I earned high honors in both my BS degree and MS degree from Oregon State. I was in near the top in most of my classes. In several classes in mathematics, I was first. In a class of over 100 students, I was always one of the first ones to complete the test. I graduated with well over 50 credits in upper division mathematics.

Past/Present Clients
My clients have been students at OSU, people who live nearby, friends with math questions, and several people every day on the PC. I would guess that you are probably going to be one more.
