Summary
An overlay of important keyboard features geared toward students who are visually impaired based on feedback by vision therapists. This tactile keyboard enlarges letters to more than 200% of their original size on a standard keyboard, and can be color coded. A great way to introduce keyboarding to younger students as well!

Lesson Plan and Activity
Objectives for 3D Keyboard with Students
Tactile keyboard with color coordination for visually impaired elementary school students learning finger placement or letter recognition while interfacing with a computer. The 3D printed letters in a bold color (organized by top, middle and lower row) help students focus their attention while searching for keys. In addition, the raised letters are 200% larger than the printed type on the standard keyboard.
Materials Needed
Requirements:
~2 contrasting PLA Filament Colors
*after the final layer of the base blocks are complete, pause the printer if you have a single color printer (like the MakerBot Replicator Mini+). Change the PLA color to a contrasting color to the base block, and resume the print job. In this way, the raised lettering will be more visible to students.
