Presentation transcript:

The TGD Project Daniel Hajas and David Turner

What is a Tactile Graphics Display? A screen for your fingers! Our TGD will use Taxels rather than pixels to represent graphical data physically. It will be a new way to interface with Maths and Science.

Why is our project needed? Nothing as capable as our project currently exists. The only competitor is the ……, which costs around £50,000 per unit! Other than that product, the only alternative for the blind are Braille displays. The Dancing Dots Active Braille Display

What are the benefits? Visually impaired people (especially Physicists!) will be able to feel graphs and diagrams. They can interact with the world on an entirely new level. A whole new set of people will be able to more easily appreciate the beauty and wonder of science

And the benefits for the sighted? There are many uses for the sighted. 3D representations of maps (representing gradients of slopes etc.) Representing 3 dimensional graphs (it can be useful to sighted scientists also!)

How far into the project are we? Interface code is written and functional, though more is always being added. 3D designs for the hardware have been created. A 3D printer is being used to print them.

What tools have we used so far? We have used several capable, open source software tools: 1.Python The Arduino IDE 3.OpenSCAD 4.Subversion We have also started to use a MakerBot Replicator 2, to create the hardware.

What does the future hold? An 8 by 8 proof of concept will be assembled. A research team has been recruited to develop new actuators. Lots and lots of funding (hopefully!)

Thank you for listening. We hope you found it interesting!
