Open source one handed keyboard.

doing God's work, making things better for the average masturtbati.

I can't read the description, but it looks like it's a full keyboard slightly curved. I'm used to seeing one handed keyboards be chording or have multiple layers, though that's for English input, like the Frogpad or twiddler. I'm not familiar with Chinese input and what it needs to have a functional set of keys.

According to automatic translation this is a project to create a left-hand-only keyboard and trackball to help a woman who lost her right hand in an accident.

No idea if it works, but it looks very cool.
