    determining textual information from the captured optical input;

    based on analyzing the optical input, wherein the analyzing comprises;

    determining a restricted optical character recognition (OCR) alphabet based on the optical input; and

    performing OCR using the restricted OCR alphabet;

    identifying desired textual information among the determined textual information based on the OCR;

    selectively providing the desired textual information to the user input interface without relying on feedback from the user; and

    wherein the user input interface is invoked in response to detecting a user interaction with a user interface element configured to receive textual information.
