Evaluating an Interface for Cross-Modal Collaborative Information Seeking

The objective of the work reported here is to develop an understanding of cross-modal collaborative information-seeking (CCIS) between visually impaired (VI) and sighted users in order to learn how best to support it. In a previous article, we reported the CCIS process that occurred when 14 pairs of users, one sighted and one VI, performed web-based collaborative information seeking tasks in two settings: co-located and distributed. In that study, participants used their tools of choice: web browsers, search engines, notetakers and communication tools. We discussed the difficulties encountered, including those imposed on VI users due to the current limitations of screen readers.
