Frogpad? What's that?
Here's another one-handed keyboard that has many advantages of the CyKey keyboard but takes a different route. It is USB or Bluetooth, not IR like the CyKey. It uses single keystrokes 86% of the time. It also uses a variant of the Dvorak keyboard layout, a proven method of more efficient typing.
Frogpad, ergonomic keyboardsQ. How does FrogPad compare to chording keyboards, such as CyKey?A. The basic difference with chording and Froggie is that the chording user must identify (and press) a unique chord (consisting of up to 4 keys) for each letter or function, while the Frog user only needs to identify the key location (and press that key) for each letter or function. Also, chording user must press and release each chord while Frog allows continuous key pressings. Having said that, these differences are more apparent when one uses either or both of these keyboards for some time. Chording and Frog share the same problem that it will take 'some'getting used to…. Yet FrogPad has a patented letter layout based on the research of Dvorak, and is much more intuitive. The learning curve is shortened dramatically. The CyKey has alphabet chords somewhat more intuitive than other chording devices, yet it will not reproduce all of the other functions of the standard keyboard."
