How firmly do those who read in braille press on the surface of the braille? (self.Blind)
submitted by darktitans
I am working on a project for the blind community. Part of the engineering requires some understanding for how the blind read in braille. Particularly, I was wondering how much force does someone who is reading in braille apply to the page or surface?
I don't know a way to exactly quantify this. I tried to research and find an actual number, but came up empty handed, so a somewhat descriptive answer can work too.

It varies a lot from person to person, as well as material. Some materials are easier to read braille off than others. Older braille paper and some other forms are paper don't hold braille as well, so it gets flattened over time... especially when people scrub over it, which flattens it down more. A lot more braille books nowadays are printed on a plastic sheet, which is much firmer and resists deformation.
Oftentimes, beginners also push much harder, until they get used to a light touch. The cause of the vision loss can also play a factor, as well. Diabetes (a leading caught of vision loss in younger people) can causes loss of sensation in the fingertips (neuropathy), which mean people push harder to try to feel something.
Also, for interpoint (braille embossed on both sides of a sheet), it can make it more difficult for some people to read, so they push harder to feel. I find that is most often dependent on paper quality, though.

https://shop.aph.org/webapp/wcs/stores/servlet/Product_Braille%20Alphabet%20and%20Numbers%20Card_1-04020-00P_10001_10001 Buy some demo braille cards or get ahold of some braille on standard braille paper and check it out!

Likely you are in Engineering School. Go to the Office of students with disabilities at your university and ask them if they have a braille document or book.

As has been said already, this varies a lot. If you need hard facts, there is no shortcut, you have to follow best engineering practices: Find a number of test subjects and do your own measurement.
