This paper describes an Idea memo PDA (Personal Digital Assistant) within an integrated environment for handwriting-based interfaces which is composed of mobile PDAs, desktop display-integrated tablets, and an interactive electronic whiteboard system. The PDA is designed to enable a user to write memos as if writing on a piece of paper; it is also designed to provide functions not possible on paper such as various ink and text-editing functions and memo-sending and receiving functions. The editing and ink recognition can be deferred to the desktop or electronic whiteboard machines which provide a higher performance, larger display areas and other physical resources. Consequently, this interface enables the user to concentrate on memo writing. The user interface of this PDA is designed to provide a user-friendly way to input a mixture of ink and text in an apparently continuous way and also to increase the rate of ink recognition.
