Keyboard vs. Treeboard, does the theory hold up

Here I do a comparison of two models of text input in a low button count setting. The applications for this would be in the areas of virtual reality, for people with disabilities or in rough settings such as on boats. Where a typical keyboard and mouse setup would be impractical or impossible to use.

head over to my site to test it out for yourself. Note that at the moment the gamepad is not published but it's only developed locally. I'll have a new release due for the next few days, where all of this and more will be included.
