Text Entry on Touchscreen Keyboards: Less is More?

When we go from mechanical keyboards to touchscreens we inevitably lose something in the translation. Yet the proliferation of tablets has led to widespread use of graphical keyboards.

You can’t blame people for demanding more efficient text entry techniques. This is the 21st century, after all, and intuitively it seems like we should be able to do better.

While we can’t reproduce that distinctive smell of hot metal from mechanical keys clacking away at a typewriter ribbon, the presence of the touchscreen lets keyboard designers play lots of tricks in pursuit of faster typing performance. Since everything is just pixels on a display it’s easy to introduce non-standard key layouts.
