On Handling Electronic Ink KAMEL, and Laboratory, WALID G. AREF, IBRAHIM Matsushita Prtnceton, Information New Jersey Technology DANIEL P. LOPRESTI Technologies, Inc., Two Research Way, Panasomc ({refibrahim,dpl} @mlt[.research.panasonLc.tom) With the growing acceptance of pen-based computers and handheld personal digital assistants (PDAs), the ability to handle handwritten data is becoming an important issue. In such an environment, writing, drawing, and gesturing with a stylus become the primary means of communication between the user and the underlying system. One approach is to treat electronic ink as a first-class datatype [Aref et al. 1995a]. It is possible to imagine a system that directly supports handwritten documents and file names, hand-drawn pictures, handwritten email messages, and the like. Representing, maintaining, and efficiently handling this new form of data raises some interesting research questions. For example, users will need to refer to files using their handwritten and search for information names, either textual or graphical-previously saved in a document. Here we discuss a new paradigm for pen computing based on bringing key functionality closer to the user, implementing it directly via electronic ink. 1. PHILOSOPHY For the most part, today s pen computers operate in a mode that might be described as
