Almost 3 years ago I shared a small web-app on HN http://hackerne.ws/item?id=715265 and got a lot of positive feedback. While I couldn't do anything right away (especially due to my cousin's health), I knew what my long-term mission was. Mid-2010 I quit my job and started working on KType http://ktype.net. After 18 months of research, learning, and coding, tonight was the first real-world test of the app and I couldn't be happier at the result. My cousin was very happy to finally 'say' something on his own and so were his parents.

I have no idea if my app will be financially successful or not but I just wanted to share this happy bit of news with HN because you guys were the ones who encouraged me to go this route. Thanks!

Nice. I'm glad to see this get some real world use. You need to get this in front of some advocacy groups.

I agree and I'm glad as well - I think it'll be really beneficial to those who have difficulty interacting and communicating with regular input devices. More people should see this!
