Keep it simple and uncluttered use ample white space or separator lines between areas. To help improve the process, here are some general tips to consider when authoring a form. 2ģ Basic design layout considerations The auto field detection process looks for certain basic form design elements.

If the PDF is tagged for accessibility, new annotations are added to the structure tree. After the form fields are named, the actual form fields are created and the tab order is set based on the interpreted reading order of the form. Field names in a table are based on information inside the cell or in the column header. For radio buttons, group labels are used to determine the field names. For objects such as underlines, text boxes, and check boxes, the text adjacent to the form field is used as the name. After form field detection, field names are assigned to each object.
Wizard dialog box In existing PDF files (or native files that have been converted to PDF), the auto field detection process looks for the same objects as scanned documents, as well as rectangles (hollow and filled), diagonal lines forming a diamond-shaped appearance, and curved lines forming a circular appearance.
The Form Wizard will convert the document to PDF and auto detect form fields in one step. To process native documents, such as Word or InDesign files, for auto field detection, open the file using the Acrobat 9 Form Wizard (Forms > Start Form Wizard) and select An existing electronic document in the Create or Edit Form dialog box. Graphic objects that are used to design forms, such as horizontal and vertical lines and stroked rectangles, are also analyzed in scanned documents. The auto field detection process can look for text including special characters, such as boxes, circles, and horizontal lines, from fonts such as Zapf Dingbats, Wingdings, and Webdings. The page only changes in the addition of form field annotations. Running OCR does not modify the original content the content still appears as an image. PDF documents that originate from scanned images automatically go through optical character recognition (OCR) first. Clicking Yes starts the automatic field detection process. Next, a dialog box opens and prompts you to decide whether to run auto field detection. In Acrobat 8 Professional, this feature was initially introduced as Run Form Field Recognition (Forms > Run Form Field Recognition). To initiate the auto field detection process on an existing PDF in Acrobat 9 choose Forms > Add or Edit Fields. Results of running auto field detection on a file that has no existing form fieldsĢ The auto field detection process Auto field detection was significantly improved in Acrobat 9 and the 9.1 update. By following certain form design practices during the authoring process, you can significantly improve the auto field detection results and substantially reduce the time it takes to develop interactive PDF forms. The detection process looks for the following types of form design elements: Underlines and boxes for fill-in areas Check boxes Radio buttons Signature areas Comb fields Tables for fill-in areas Auto field detection does not process combo boxes (sometimes called drop-down lists), list boxes, and barcodes. The algorithm can process electronic forms from scanned documents and certain native document files. The auto field detection feature uses an algorithm to determine when field objects can be created in a form. If you follow some basic guidelines when designing electronic forms in authoring programs, such as Adobe InDesign or Microsoft Word, you can significantly improve the auto field detection process.
