Collaborating over Portable Reading Appliances.


Reading appliances or e-books hold substantial promise to help us collaborate. In this paper, we use a study of a group activity – a reading group that meets to discuss articles of mutual interest – to explore four scenarios for collaborating with e-books: (1) meetings and face-to-face discussions; (2) serendipitous sharing of annotations, as when we borrow a document from a colleague or buy a used book; (3) community-wide use of anonymous annotations to guide future readers; and (4) e-books as a basis for initiating interaction between people. In so doing, we describe some methods for implementing these facilities, and introduce design guidelines.
