Whiteboard sharing: capture, process, and print or email

Whiteboards support face to face meetings by facilitating the sharing of ideas, focusing attention, and summarizing. However, at the end of the meeting participants desire some record of the information from the whiteboard. While there are whiteboards with built-in printers, they are expensive and relatively uncommon. We consider the capture of the information on a whiteboard with a mobile phone, improving the image quality with a cloud service, and sharing the results. This paper describes the algorithm for improving whiteboard image quality, the user experience for both a web widget and a smartphone application, and the necessary adaptations for providing this as a web service. The web widget, and mobile apps for both iPhone and Android are currently freely available, and have been used by more than 50,000 people.
