Classifying The Intent Of User Input
First Claim
Patent Images
1. A method comprising:
- obtaining touch information regarding a single object touching a common input area of an input device, the input device supporting multiple different user intents for the single object touching the common input area; and
determining, based on the touch information, which of the multiple different user intents is intended for the single object touching the common input area, the multiple different user intents including a key strike and at least one other type of input.

Abstract
Different types of user inputs can be input by a user via a keyboard of an input device. These different types of user inputs include, for example, key strikes, multi-touch interactions, single finger motions, and/or mouse clicks. Touch information regarding the pressure applied to the keys of a pressure sensitive keyboard over time (or the contact area of the user input for other types of keyboards over time) is used to classify the intent of the user input as one of the various types of user inputs.

4. (canceled)
- 13. An apparatus comprising an input device configured to provide an output that indicates touch information regarding a single object touching the input device, the input device supporting multiple different user intents for the single object touching the input device, the output being usable by one or more modules to automatically distinguish between the multiple different user intents in determining which of the multiple different user intents is intended by the single object touching the input device, the multiple different user intents including a key strike and at least one other type of input.

20. A method implemented in a pressure sensitive keyboard input device, the method comprising:
-
obtaining, at the pressure sensitive keyboard input device, touch information regarding a single object touching the pressure sensitive keyboard input device, the pressure sensitive keyboard input device supporting multiple different user intents for the single object touching the pressure sensitive keyboard input device; and determining, at the pressure sensitive keyboard input device and based on the touch information, which of the multiple different user intents is intended for the single object touching the pressure sensitive keyboard input device, the multiple different user intents including a key strike and a movement, the determining including determining that a movement is intended in response to the single object travelling a threshold distance or having a threshold velocity, and determining that a key strike is intended in response to a force graph generated based on the single object touching the pressure sensitive keyboard input device having a shape that matches a force graph of a key strike.
