Problem
Setting: People
with visual impairements identify objects mostly by touching them.
However, lots of objects have identical shape. I did some research
and found out that this causes significant difficulties for people
with low vision. For example, often they cannot distinguish between
milk and juice packages in the fridge. Or sometimes it is not really
handy or hygienic to touch the contents of packaging (e.g. cream
cheese or curds). The
Solution: To
solve this problem I constructed the brail tag. To
identify an object, you just select the brail letter which stands
for a product name on the tag and attach the tag to the product. For
example, if you want to distinguish milk and orange juice cartons you
can add the tag with the letter “O” for orange juice and “M”
for milk. Tips
for printing: I
used PLA as material Layer
hight 0.1 mm the
small parts must lie on the side after
printing cut the little windows clean, the bottom layer is causing
problems with dimensional accuracy. Tips
for assembling: The
long (and rounded)pins must be inserted into the little windows and
the side with the short pins point to the center of the housing Important:
after placing all the small parts you combine the the upper und lower housing Now
comes the interesting part: You have to melt the both sides of the
braille tag to finish the assembly, best way to do it is a heated
printing bed if available or heat up a screwdriver and push against
it(see picture of how to do it and how not to do it(overheat+soot) Further
project and functionaly development: Product
dating information (expiration date) tags. TBH I just didn't have
enough time to add this functionality : ( Best
