REDUCING ERROR RATES FOR TOUCH BASED KEYBOARDS

摘要

The present technology provides systems and methods for reducing error rates to data input to a keyboard, such as a touch screen keyboard. In one example, an input bias model dynamically changes the keyboard functionality such that the keyboard will not necessarily produce the same result for an identical tap coordinate. Rather, the keyboard functionality is adapted to account for key offset bias that occurs when the user has a tendency to select a tap coordinate that would otherwise return an unintended key. Additionally, the present technology provides a language feedback model that may provide a probability for a next tap coordinate and may augment the key corresponding to the most probable next tap coordinate, thereby allowing the user to more easily select the correct key. Further details are provided herein.

1. A method for reducing error rates associated with key input to a keyboard, the method comprising:
detecting at least one keyboard event,
wherein the detected keyboard event includes a set of coordinates indicated by a touch of a user on a keyboard, andwherein each key on the keyboard is represented by coordinates defining an area on the keyboard for that key; determining an intended input key based on the detected keyboard event, wherein determining the intended input key includes:
determining multiple candidate keys near to the set of coordinates indicated by the touch on the keyboard;calculating a probability for whether each of the multiple candidate keys was the intended input key; and,updating the defined area for a key on the keyboard based on the determined, intended input key.
