5.29. COBRA-Key+O: launch screen text recognition

When you launch screen text recognition with COBRA-Key+O, a bitmap of the screen content is transferred to the Text Recognition application which then recognizes the text. During this time you will hear successively “OCR is installed”, “load Bitmap”, “Bitmap recognized” and “Saving text”. The data will not be available until you hear “Text recognition complete”.

You can browse the text on your screen with the navigation functions, the Windows key, Level 0 on the Keypad or the navigation keys on your Braille Display . No cursor is available here.

You can also click on the text – the click will operate on exactly that letter upon which you have clicked.

To return to the original screen, Refresh the screen content with COBRA-Key+F5 .

This function is useful when applications or Internet pages contain unnamed graphics, or when you encounter a text which has been saved only as an image, e.g. screenshots or copies of the screen.

You can use COBRA as a straightforward screen reader to read PDF files which have been saved as images only.

You can thus use graphic installation programs or update the firmware of a Nokia mobile ’phone.


The result is saved in the OUT.RTF file in the COBRA directory.

See the chapter “Questions and answers about text recognition” for further information.
