MODIFYING AN ON-SCREEN KEYBOARD BASED ON ASYMMETRIC TOUCH DRIFT

摘要

Utilization of error vector data representative of errors between the location of actual keystrokes and the location of determined intended keystrokes to compute “bias” data indicative of the magnitude and direction of error vectors for a given location on the virtual keyboard is disclosed. This bias data can then be used to perform a number of operations such as keyboard re-spotting.

主权项

1. A computing device, comprising:
a touch screen configured for displaying a user interface; and a processor communicatively coupled to the touch screen and capable of
processing touch location error data obtained at a plurality of touch locations on the user interface to generate bias data, the touch location error data including a plurality of touch location errors between actual and intended touch locations, the bias data representative of one or both of first and second components of the touch location errors along first and second dimensions, andmodifying the user interface based on the bias data.
