Free registration required

Executive Summary

This paper presents iAnnotate, a tool that provides multi-user digital ink annotation on standard web pages within a commercial browser. The annotation can be saved, retrieved and shared with others via a URL. In addition multiple users' annotations can be displayed on the same page. The paper describes the design goals and the technical challenges. While realizing annotation on web documents is difficult because of the dynamic nature of the documents and the security constraints of web browsers, the user evaluation suggests that fully realized digital ink annotation tools would be very valuable.
