Abstract
Devices and methods are disclosed which relate to improving the efficiency of text input by generating a dynamic virtual keyboard. Disclosed examples display a soft keyboard on a touchscreen of a text-entry device. The touchscreen works with the soft keyboard as a form of text input. Keyboard logic on the text-entry device is programmed to change the sensitivity of the footprint of keys surrounding a predicted key or keys, based upon the prior entry. The keyboard logic assigns a prediction value to each key based on a statistical probability that the key will be entered next. The touchscreen displays a dynamic virtual keyboard based on these prediction values. Enhancements include reducing the sensitivity of the footprint of keys relative to their prediction value. For instance, if a key is very unlikely to be the next intended key pressed, the footprint of the key will only respond to a key press of greater force than a key which is likely to be entered next.
