Abstract
During an information-extraction technique, visual suitability indicators may be displayed to a user of the electronic device to assist the user in acquiring an image of a document that is suitable for subsequent extraction of textual information. For example, an imaging application executed by the electronic device may display, in a window associated with the imaging application, a visual suitability indicator of a tilt orientation of the electronic device relative to a plane of the document. When the tilt orientation falls within a predefined range, the electronic device may modify the visual suitability indicators to provide visual feedback to the user. Then, the electronic device may acquire the image of the document using an imaging device, which is integrated into the electronic device. Next, the electronic device may extract the textual information from the image of the document using optical character recognition.
