The Hershey Public Library has a device available for patrons to borrow with a library card. It is a portable scanning pen which reads printed text out loud using an embedded camera, a real-time optical character recognition and natural voice text to speech. Not only does the reader pen read text out loud, it can look up words in a dictionary and show definitions. It can scan and save text and upload the text file via USB to a computer to be retrieved and listened to later. It even has a voice memo function. This tool is helpful to those who suffer from reading difficulties, such as dyslexia.
