It's $200, which makes it a bit expensive, but compared to existing systems which can cost well over $5000, it's much more affordable. I'm trying a head/glasses mounted display called Vufine+, which is just a screen with no other features. I think using a small head mounted display or smart glasses would make a switch scanning system less obtrusive, easier to set up, and more portable. Switch scanning trades the difficulty of positioning for reduced speed. I have another idea for eye tracking, but each solution has its pros and cons. Eye tracking is a good option, but it can be difficult to position correctly, and means the screen has to be right in front of them. The main options I've explored are eye tracking and switch scanning. While my initial motivation could be considered selfish because it's for my benefit, but I want to help others if I can. I've been working on various ideas the past few years, and this is one of them. I have a type of muscular dystrophy and my speech is getting hard to understand, which is very isolating.

I plan to write a simple switch scanning program which will run on Raspberry Pi Zero which will be optimized for a miniature screen. This presents a few challenges which I think I can solve. My idea is that since a large screen is bulky and obtrusive, it would be better to use a small head mounted display instead.
Then the process repeats until the user is finished typing.
This has to be mounted to a wheelchair and that creates another physical barrier with the world.Ī common solution is called switch scanning (think Stephen Hawking), which means a grid of letters or words is displayed on a screen, and individual boxes are highlighted, one after another, and the user presses a button when the box they want is selected. There are various devices that can allow them to speak, but most are extremely expensive and and usually are at least the size of tablets. People with conditions such as ALS and some forms of muscular dystrophy can lose the ability to speak effectively (or at all).
