Keyword(s): collaborative inking, shared canvas, InkML

Abstract: We present techniques that allow sharing of standardized digital ink in a heterogeneous collaborative environment. We explore the use of W3C InkML (Digital Ink Markup Language) and show how it is more flexible and suitable than other digital ink formats for this purpose. We discuss different possible digital ink sharing schemes using InkML and describe pros and disadvantages of each. We present our implementation of a shared whiteboard collaboration system for sharing digital ink across different devices and platforms. We discuss several usage scenarios such as collaborative document annotation and map annotation etc in which our system can be used for sharing digital ink in an efficient manner.
