US 11,899,928 B2 · Virtual keyboard based on adaptive language model

Abstract

Disclosed herein are related to systems and methods for providing inputs through a virtual keyboard with an adaptive language model. In one approach, one or more processors determine whether a user intended to provide semantically meaningful characters or not, when providing a hand motion or a hand pose with respect to a virtual keyboard. The virtual keyboard may be located on a surface without physical keys. In one approach, the one or more processors determine an input to the virtual keyboard based on the hand motion or the hand pose. In one approach, the one or more processors determine weight of a language model according to the determined user intention. In one approach, the one or more processors modify the detected input according to the determined weight of the language model.

Dependent claims

A method comprising:

determining, by one or more processors, a level of focus of a user when providing a hand motion with respect to a virtual keyboard;
detecting, by the one or more processors via an image sensor, an input to the virtual keyboard based on the hand motion;
determining, by the one or more processors, weight of a language model according to the determined level of focus of the user;
determining, by the one or more processors through the language model, a semantically suitable replacement corresponding to the determined weight;
and
modifying, by the one or more processors, the detected input according to the determined semantically suitable replacement corresponding to the determined weight.
