>From their lit: MUSIC, MATHS, TABLES, DIAGRAMS & LITERATURE
Canute 360 is ideal for use at home, the classroom or the office.

Literature, musical notation, charts, graphs, mathematics, tables and
spacial diagrams. All these are hugely more practical on a nine-line
refreshable Braille display than a single line display, ream of embossed
paper or through text-to-speech.

For schools and educational institutions Canute can drastically increase
availability of Braille material. It reads all pre-formatted Braille Ready
Files (BRF) and Portable Embosser Files (PEF), meaning you can read texts
from Bookshare, the RNIB Library or any other Braille library in the world.
Using transcription software such as Duxbury DBT or Braille Blaster any
digital text file can be transferred to and read on Canute.

The Canute's 'hard' signage quality Braille makes Canute ideal for beginners
and young children learning Braille.

Cheers,
Neal

Hello Rejin,
That is the least expensive multiline tactile display. If you want to work
on inventing a less expensive multiline tactile display, there is
definitely a very low level of competition and high level of need!
You may want to check out Sonification tools:
http://sonify.psych.gatech.edu/research/sonification_sandbox/
Or the web version:
http://editor.highcharts.com/sonification-studio/#/
or
https://workspace.google.com/marketplace/app/audiographs/1078303178825
or
http://support.sas.com/software/products/graphics-accelerator/

These have a significantly smaller price tag, and get the job done for the
most part.
If you really want tactile graphics, then I would recommend one of the
swell paper machines:

r.html
or an inexpensive tactile embosser:

Hope this helps!
Thanks,
