MOBILE NAVIGATIONAL CONTROL OF TERMINAL USER INTERFACE

Abstract:

A mobile device establishes an indirect network connection to a User Interface (UI) agent of a terminal. The indirect connection managed as a mobile navigational control session maintained through a server or through the server and a proxy. A keyboard widget/object and a navigation-selection widget/object are rendered within a mobile screen on a display of the mobile device. During the session, a user interacts with the keyboard and/or navigation-selection widgets and corresponding UI key events are forwarded to the UI agent. The UI agent provides the UI key events as Human Interface Device (HID) key events to the terminal causing a transaction interface to update transaction screens being rendered on a transaction display of the terminal during a transaction. The user conducts the transaction at the terminal without touching the transaction display and controls the transaction screens for the transaction via the keyboard and navigational widgets from the mobile device.
