Abstract

An apparatus is provided that includes a processor to at least perform or cause the apparatus to at least perform a number of operations. These operations include receiving pressure-measurement signals from a keyboard including an arrangement of keys, and a plurality of pressure sensors associated with a respective plurality of the keys. In this regard, the pressure sensors are configured to measure a pressure applied to the respective plurality of the keys, and produce the pressure-measurement signals representative of the measured pressure. The operations also include predicting one or more next keystrokes on the keyboard as a function of the pressure-measurement signals, and determining one or more commands or instructions for directing performance of one or more operations of an apparatus or software operating on the apparatus, where the command(s) or instruction(s) are determined as a function of the predicted next keystroke(s).

3. The apparatus of claim 1, wherein predicting one or more next keystrokes includes predicting one or more next keystrokes based on an inferred probability of a next key to be pressed, the probability of the next key being pressed being inferred based on the pressure-measurement signals and keyboard utilization patterns.

4. The apparatus of claim 3, wherein the probability of the next key being pressed is inferred based on keyboard utilization patterns one or more of which is acquired through a machine-learning technique.

5. The apparatus of claim 1, wherein determining one or more commands or instructions includes determining one or more commands or instructions that effectuate a change in a graphical output presented by a display during operation of the software operating on the apparatus.

6. The apparatus of claim 1, wherein determining one or more commands or instructions includes determining one or more commands or instructions otherwise performed by the apparatus or software in response to an actual keystroke corresponding to the predicted next keystroke.

7. The apparatus of claim 6, wherein determining one or more commands or instructions includes determining one or more commands or instructions that initiate an operation by or with another apparatus located across a network from the apparatus.

8. The apparatus of claim 1, wherein determining one or more commands or instructions includes determining one or more commands or instructions further as a function of one or more of information regarding the software or a type of the software operating on the apparatus, a state or a responsiveness of the software or the type of the software.

9. A method comprising:

receiving pressure-measurement signals from a keyboard comprising an arrangement of keys, the pressure-measurement signals from the keyboard corresponding to a plurality of pressure sensors associated with a respective plurality of the keys, the pressure sensors being configured to measure a pressure applied to the respective plurality of the keys, and produce the pressure-measurement signals representative of the measured pressure;

predicting one or more next keystrokes on the keyboard as a function of the pressure-measurement signals corresponding to the plurality of pressure sensors associated with the respective plurality of the keys; and

determining one or more commands or instructions for directing performance of one or more operations of an apparatus or software operating on the apparatus, the one or more commands or instructions being determined as a function of the predicted one or more next keystrokes,

wherein receiving pressure-measurement signals, predicting one or more next keystrokes and determining one or more commands or instructions are performed by a processor of the apparatus, the processor being configured to receive pressure-measurement signals, predict one or more next keystrokes and determine one or more commands or instructions.

10. The method of claim 9, wherein predicting one or more next keystrokes includes determining when the pressure-measurement signals from a pressure sensor associated with a respective key indicates an increase in pressure at a rate above a given threshold rate, or indicates a pressure above a given threshold pressure.

11. The method of claim 9, wherein predicting one or more next keystrokes includes predicting one or more next keystrokes based on an inferred probability of a next key to be pressed, the probability of the next key being pressed being inferred based on the pressure-measurement signals and keyboard utilization patterns.

12. The method of claim 11, wherein the probability of the next key being pressed is inferred based on keyboard utilization patterns one or more of which is acquired through a machine-learning technique.

13. The method of claim 9, wherein determining one or more commands or instructions includes determining one or more commands or instructions that effectuate a change in a graphical output presented by a display during operation of the software operating on the apparatus.

14. The method of claim 9, wherein determining one or more commands or instructions includes determining one or more commands or instructions otherwise performed by the apparatus or software in response to an actual keystroke corresponding to the predicted next keystroke.
