3D periodic table in Braille.

If you are blind or VI and want to try
out a portable braille version of the
chemical elements in 3D book form,

You will be asked about your
situation, condition, and address
for sending the ElementBook
model and requirements.

I have developed a method of adapting my
3D Alexander Arrangement of Elements
concept for use by the blind, and wish to learn from visually handicapped students, their aids, and teachers, what changes are needed before developing a final production model.


By transforming the visual chemistry concepts of the periodic table into a tactile manipulative, VI students can be more successful in the chemistry classrooms with immediate data reference.

Braille and large print symbols have been applied to a conveniently sized Braille periodic table where the element number sequence is absolutely continuous from the first to last, eliminating the dozen plus times one must jump to the next element, plus element blocks identifiable by shape and size. It is so small that it can accompany the student all day!

The atomic numbers and element symbols would be Brailled in 'data boxes' on the vertical surface of the several hinged 'pages' representing the blocks (with p- and s-block together), correctly sequenced to each other.

By doing this, and using my patented downslant of element rows bringing one period to the next - with group/family elements still intact - one may trace all the elements from beginning to end without (pun intended) 'lifting a finger'.

A miniature of the ElementBook art for Beta Test version, showing (in black) the raised dots and lines to be imposed over very large color element symbols is below, to be cut out and folded to understand how the 30" wide periodic table collapses to fit in a lab coat pocket.
