Web-based applications using pen-based interfaces and network-based on-line handwriting recognition

This paper presents several applications and their user interfaces that employ pen-based interfaces and network-based on-line handwriting recognition. Pen-based interfaces are again attracting people's attention since several platforms are now available such as Microsoft Tablet PC, Anoto pen and paper, E-pen and many more. We are interested in employing them for WWW applications. We have developed several pen-based applications such as handwritten memo application, questionnaire answering application, crossword puzzle application, etc. All the applications send handwriting to the handwriting recognition server when necessary to have it recognized by the server so that they do not need to employ handwriting recognition themselves. We discuss their merits and the UI design based on the client-server handwriting recognition architecture.
