Viewing tip

I recommend that you open another copy of this document in a separate browser window and use the following links to easily find and view the figuresand listings while you are reading about them.


  • Figure 1 . Image from the file named Svg23.svg.


  • Listing 1 . Code requiring changes.
  • Listing 2 . Complete listing of the program named Svg23.java.
  • Listing 3 . Batch file to compile and run the program named Svg23.java.

Supplemental material

I recommend that you also study the other lessons in my extensive collection of online programming tutorials. You will find a consolidated index at www.DickBaldwin.com .


Creation of tactile graphics

The module titled Manual Creation of Tactile Graphics explains how to create tactile graphics from svg files that I will provide.

Normally in these modules, I provide the SVG files that you need to create tactile graphic. However, in this module, you will create your own SVG file byediting, compiling and running a program that I will provide named Svg23.java .

What is the IVEO Hands-on-Learning System ?

A disclaimer

I have no affiliation with ViewPlus Technologies Inc. , the manufacturer of the IVEO system, other than being an acquaintance and admirer of Dr. John Gardner, President and Chief Technical Officer of thecompany. However, as an independent observer, I believe that IVEO is a great system and I wish it were possible for every student to have access tosuch a system.

The words that you see here are my words, except for a few words that I copied from the ViewPlus website and presented in quotation marks earlier .

A description by the manufacturer

I will begin by referring you to an article written by John Gardner titled Accessing Graphical Information with IVEO SVG at (External Link) . I recommend that you read that article first and then come back and finish reading this module.

The component parts

If I understand it correctly, a complete IVEO System consists of the following components:

  • A computer
  • An embossing machine capable of producing embossed or tactile graphics
  • A free program called the IVEO Viewer that can be downloaded from (External Link)
  • A large 11x14 touchpad

In this module, I will assume that you have the necessary computer. I will alsoassume that you don't have a suitable graphics embossing machine but instead you have a friendly sighted assistant who is willing to manually emboss therequired printed image for you.

I will assume that you can download the IVEO Viewer software.

I will assume that you do not have an 11x14 touchpad, but instead you are able to come up with a suitable USB digitizing tablet. I will write this modulearound the use of a rather antiquated Wacom 5.0 x 3.62-inch digitizing tablet that I have owned for quite a few years. Your digitizing tablet will probably be a differentsize, so I will explain how to accommodate the difference is size.

I will also assume that you can download and install the free Inkscape program from (External Link) . That program will be needed to flip and print an SVG file to produce a mirror image that your assistant can manually embossfrom the back side.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
