In some embodiments, the user interface is further configured to present other interactive elements that may include, for example, television home page controls, search controls, message button controls, mailbox controls, browser controls, favorites controls, signal bar controls, and the like.
In some embodiments, the interactive element may also be operated by a sensor, which may be, but is not limited to, an acoustic input sensor, such as a microphone, which may detect a voice command including an indication of the desired interactive element. For example, a user may use a voice command to "launch a virtual numeric keypad" to trigger the launching of a system setup application, or any other suitable identification, to identify a desired interactive element, and may also describe that a desired action associated with the desired interactive element is to be performed. The controller may recognize the voice instruction and submit data characterizing the interaction to the UI or its processing component or engine.
