Abstract: A gaze virtual object is displayed that is selectable based on attention directed to the gaze virtual object to perform an operation associated with a selectable virtual object. An indication of attention of a user is displayed. An enlarged view of a region of a user interface is displayed. A value of a slider element is adjusted based on attention of a user. A user interface element is moved at a respective rate based on attention of a user. Text is entered into a text entry field in response to speech inputs. A value for a value selection user interface object is updated based on attention of a user. Movement of a virtual object is facilitated based on direct touch interactions. A user input is facilitated for displaying a selection refinement user interface object. A visual indicator is displayed indicating progress toward selecting a virtual object when criteria are met.

Abstract: The invention provides a transparent encryption infrastructure which allows the user to point-and-click on columns and tables to encrypt data. The creation of triggers and views are also easily implemented, to encrypt and decrypt data, to manage the encryption keys and to grant and revoke access to a column. Public and private key pairs are hashed and encrypted with a valid password. The process or encryption starts by creating a randomly generated symmetrical key, encrypting the symmetrical key with the private key for each user authorized to decrypt the data, and storing the encrypted symmetrical key, along with the user's name and the column name, in the database.
