Visual Impairment Computer Assistant

Inspiration

I wanted to do something using java's robot class since I haven't tried it before. I also wanted to make something that could help people.

What it does

It adds a magnifier to the screen, a large crosshair follows the cursor to assist people with seeing where the cursor is on the screen, it has a color blind option where the magnifier will try to make red and green areas on the screen more visible to people with red/green color blindness.

How I built it

I coded it from nothing. I just had the idea and wrote the code.

Challenges I ran into

It was difficult to think of a way to help people with color blindness tell the difference between red and green without causing other colors to look the same, it was also hard to figure out how to draw a crosshair on the screen that wouldn't interfere with being able to use the mouse.

Accomplishments that I'm proud of

I got the cross hair to work by creating an invisible window that follows the cursor. I've never done that before and it actually works very well.

What I learned

How to use java's robot class and how to make a "tooltip" visible on the screen.

What's next for Visual Impairment Computer Assistant

Add more features like a Blue/Yellow color blind assist mode and options to move the magnifier to different sides of the screen so it doesn't get in the way.
