Abstract

Devices and methods are disclosed which relate to improving the efficiency of text input by dynamically generating a visually assistive virtual keyboard. Exemplary variations 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 visual appearance of each key within the soft keyboard based on 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 visually enhanced keyboard based on these prediction values. Enhancements include resizing keys relative to their prediction value, rearranging the keys a distance from the previous key entered inverse to its prediction value, etc.

assigning, based upon the key a plurality of prediction values to the plurality of numerical keys in response to detecting the input, wherein each of the plurality of prediction values is based upon a statistical pattern from a contact list, wherein the contact list comprises an entry comprising the telephone number, and wherein the plurality of prediction values comprise probabilities that a corresponding numerical key of the plurality of numerical keys will be a numerical key selected next, and wherein the corresponding numerical key corresponds to a next digit in the telephone number, and

visually enhancing the dynamic keyboard based upon the plurality of prediction values, wherein visually enhancing the dynamic keyboard comprises altering an appearance of the dynamic keyboard based upon the plurality of prediction values and displaying a visually enhanced dynamic keyboard, wherein altering the appearance of the dynamic keyboard comprises

shrinking a second numerical key of the plurality of numerical keys based upon a first corresponding prediction value,

enlarging a third numerical key of the plurality of numerical keys based upon a second corresponding prediction value,

changing a color of fourth numerical key of the plurality of numerical keys based upon a third corresponding prediction value, and

changing a distance between the first numerical key and a fifth numerical key of the plurality of numerical keys based upon an inverse of a fourth corresponding prediction value.

2. The device in claim 1, wherein altering the appearance of the dynamic keyboard comprises resizing each of the plurality of numerical keys in proportion to the plurality of prediction values.

3. The device in claim 1, wherein altering the appearance of the dynamic keyboard comprises changing distances between each of the plurality of numerical keys and the key associated with the input detected.

4. The device in claim 1, wherein altering the appearance of the dynamic keyboard comprises changing a color of each of the plurality of numerical keys based upon the plurality of prediction values.

5. The device in claim 1, further comprising a transceiver.

6. The device of claim 1, wherein altering the appearance of the dynamic keyboard comprises exchanging a fifth of the plurality of numerical keys with a sixth of the plurality of numerical keys based upon a fifth corresponding prediction value.

7. The device of claim 1, wherein displaying the visually enhanced dynamic keyboard comprises displaying the visually enhanced dynamic keyboard on the touchscreen.

8. The device of claim 1, wherein displaying the visually enhanced dynamic keyboard comprises projecting the visually enhanced dynamic keyboard using an optical laser of a device that communicates with the device via wireless signals.

9. A method comprising;

displaying, at a device comprising a touchscreen and a processor executing a keyboard logic, a dynamic keyboard having a plurality of numerical keys appearing to have substantially the same size on the touchscreen;

detecting, by the processor, input corresponding to entry of a key on the dynamic keyboard, wherein the input detected comprises entry of a first numerical key corresponding to a first digit in a telephone number;

assigning, by the processor and based upon the key entered, a plurality of prediction values to the plurality of numerical keys in response to detecting the input, wherein each of the plurality of prediction values is based upon a statistical pattern from a contact list, wherein the contact list comprises an entry comprising the telephone number, and wherein the plurality of prediction values comprise probabilities that a corresponding numerical key of the plurality of numerical keys is to be a next key selected, and wherein the corresponding numerical key corresponds to a next digit in the telephone number; and

visually enhancing, by the processor, the dynamic keyboard based upon the plurality of prediction values, wherein visually enhancing the dynamic keyboard comprises altering an appearance of the dynamic keyboard based upon the plurality of prediction values and displaying a visually enhanced dynamic keyboard, wherein altering the appearance of the dynamic keyboard comprises

shrinking a second numerical key of the plurality of numerical keys based upon a first corresponding prediction value,

enlarging a third numerical key of the plurality of numerical keys based upon a second corresponding prediction value,
