OCR Scanner
Intro
The OCR scanner is used as an alternative way of input when the user is completing a form. The scanner recognizes and picks up specific text from an object or document, and enters it into the form for the user.
OCR scanner examples
The OCR scanner comes within a full-screen modal that includes a navigation bar, scan window, alignment guide.
A. Navigation Bar
The navigation bar is composed of a “Cancel” button, title, an optional settings, and the flash icon.
B. Scan Window

C. Alignment Guide
The alignment guide provides guidance to the user when pointing the camera to text. It can be configured to the form of the object that the user is aligning to.

The interaction of the OCR scanner consists of four steps.
Launch
The scanner is usually launched from tapping on the camera icon in a text field if it is a single-field scan or an add icon if it is a multi-field scan.
Scan
The scanner launches in a modal with a navigation bar and alignment box. The user may start aligning the object in the box.
Text Recognized
As soon as text is recognized by the scanner, a line of text appears as feedback to the user displaying what the scanner has picked up.
Confirmation
The scanner dismisses automatically and returns to the form with scanned text in the text field.

The alignment box can be configured to various sizes depending on the object the user is aligning to. If the user is looking for a specific line of text, one option is to provide a short alignment box for the user to select a single line of text only.
