Today high in the Japanese Alps, my partner had a skiing injury. The medical insurance wanted copies of airline tickets, passports, receipts and contracts sent through immediately. Fortunately I have a portable document scanner on my iPad. Making it my most useful app of the day!
This is a really useful tool in the classroom, office or when you are traveling. There are a number of scanning applications. Some use OCR optical character recognition, that turn the text or image into digital characters. You can edit these, adjust shades and contrasts to create the text or image that you need. These images can be saved as pdf’s or jpg’s and can be used creatively to create artworks.
My current favorites are Doc Scan HD and Perfect OCR. Doc Scan Hd claims to be able to scan curled or folded documents. You can scan diagrams on the white board,receipts and business cards and pictures from your photo collection. What I like is that you can edit and annotate the scanned images. This is very useful as a teaching tool.
You can save the image as a PDF and email it or place it in ibooks, drop box, evernote or google docs and send the link to share it with a colleague or your students. The free version of Doc Scan Hd allows you to scan a three page document for longer documents upgrade to the paid pro version for $4.49
Perfect OCR works well with high quality script recognition for text in different languages and typefaces.I would like to hear your comments on how you are using these scanning apps in your teaching.
