Problem Statement
 
Our goal is to build a device that can help those with autism communicate with
others.
Assistive and Augmentative Communication (AAC) devices exist to allow people to
communicate in more ways
Types range from “card readers” to high end tablets.

How?
Raspberry Pi
Popular Single Board Computer
Many Available Add-ons
Arduino DUE
Popular Hobby Board, No Display Drivers
BeagleBone
Popular Hobby Board, Not designed for
Displays
 
How Many Board Design?
 
Golden Design: Everything made and designed by our group
The Reality:
Using Solutions already made so that there is time to get to our own form of solution
A massive team of engineers would be needed for the “Golden Design”.
Issues with a single board design:
Requires fully laying out a board:
Including Matched memory lines and countless other requirements.
Special facilities
Team needs to learn how to lay out a multi-hundred component board
More flexibility with a multi-board design.

Our project "A Voice for Autism" aims to create a user-friendly, cost-effective assistive communication device for individuals with autism. Existing devices are expensive and cumbersome, so our team is developing a solution that is affordable, efficient, and customizable to meet the diverse needs of users. Through rigorous testing and design considerations, we strive to provide a reliable and empowering tool for enhancing communication abilities. Our focus is on inclusivity, functionality, and practicality.
