Hi Zoltán,

I will say up front that I am a commercial member here, but one who, after over 30 years of experience in this industry, tries not to be biased.

I could not agree with you more about braille and mathematics.  Speech is extremely difficult to follow, particularly with advanced maths.

Ideally with complex equations, the ideal way to view these is with braille on paper.  A one line braille display cannot do this.

However, a new British designed and developed device called the "Canute 360", while essentially a braille e-book reader, is capable of displaying BRF files, where 9 lines of 40 braille cells can be displayed at one time.  And at under £2,000 (UK Pounds).

If you would like to see more details, go to http://bristolbraille.co.uk/ or our own web site below in my signature.

All the best,

Dear Saaqib Mahmood

I think that Braille is essential for learning mathematics. I can only imagine solving problems of matrices, more complex systems of equations, in the case of blind people.In my experience, blind people who do not know Braille find it very difficult to master mathematics in high school.If they do not know mathematics, they will not know higher statistics, nor will they be able to program properly. It is important for Eles to do well in the blind.

Regards.

Sincerely,

Zoltán Rozemberczki

Hi BlindMath mates? How are you?
I've been for the past few days learning the UEB mathematics braille through the UEB Math Tutorial on the APH Tech website.
I've just covered the section on matrices, which is Lesson 7.3 in the tutorial.
I'm wondering if it is practical for the blind people to handle the elaborate calculations and manipulations of the higher mathematics (i.e. mathematics above grade 8) in braille on a paper, especially use the upside down writing frame. 

What is the most convenient option for a blind UEB user to do the complex higher mathematics?
Of course, a UEB reader can read mathematics books alright. 

The real challenge is when it comes to working out the problems and presenting one's proofs and solutions in braille. 

For example, suppose a blind person is asked to evaluate a complicated anti-derivative (i.e. indefinite integral), or perform a complicated Gaussian elimination using matrices, and show his or her attempt clearly using the UEB mathematics code. What would be the best option available to a totally blind person, especially somebody using a slate-and-stylus? How best can he or she come up with a correct answer and present his or her work accurately?


Regards.

Sincerely,
Saaqib Mahmood
