Apparatus and method for providing adaptive on-screen keyboard
First Claim
1. An apparatus for providing an adaptive on-screen keyboard, comprising:
- a sensor for detecting at least one contact corresponding to a touch action of a user from a touch screen;
a pattern recognizer for recognizing at least one first key of the on-screen keyboard corresponding to each contact;
a rearrangement processor for reconstructing a key arrangement of the on-screen keyboard based on an obtained curve passing a midpoint of the at least one contact and mapping the at least one first key to a region defined by the obtained curve; and
a display for displaying the adaptive on-screen keyboard on the basis of information on the reconstructed key arrangement.

Abstract
An apparatus and method for providing an adaptive on-screen keyboard are provided. The apparatus includes a sensor for detecting touch action of a user from a touch screen, a pattern recognizer for recognizing a touch pattern of the user using the detected touch action of the user, a rearrangement processor for reconstructing the key arrangement of the on-screen keyboard to be provided through the touch screen on the basis of the recognized touch pattern of the user, and a display for displaying the on-screen keyboard on the basis of information on the reconstructed key arrangement. Thus, the apparatus can increase the convenience of use when the user makes use of the on-screen keyboard.
