You can! If you have a printer, below the image you'll find two links with a printable layout tester. Print it at 100% scale (or no scale), and you can try the Kyria layout on paper. It won't be exactly the same as using the actual keyboard, but it'll be sure to help you get a feeling about it. If placing your fingers at the shaded squares feels comfortable, it might be the keyboard for you!
