          The need for exploration comes from users’ information needs that are highly complex: open-ended and multi-faceted information needs that are derived from complex search tasks such as learning tasks. Researchers have shown that exploratory search can be better supported through explicit search collaborations. More importantly, previous research has suggested that leveraging collaborations of a large group of users may lead to an improved user experience. However, there is still a lack of evidence in support of this hypothesis as past studies were usually conducted in restricted environments (laboratory studies with small groups of participants and simulated work tasks). In this paper, we briey discuss how we will shed light on this research field, and we present current work and future directions.

          Coordinating cognition: the costs and benefits of shared gaze during collaborative search.

          Collaboration has its benefits, but coordination has its costs. We explored the potential for remotely located pairs of people to collaborate during visual search, using shared gaze and speech. Pairs of searchers wearing eyetrackers jointly performed an O-in-Qs search task alone, or in one of three collaboration conditions: shared gaze (with one searcher seeing a gaze-cursor indicating where the other was looking, and vice versa), shared-voice (by speaking to each other), and shared-gaze-plus-voice (by using both gaze-cursors and speech). Although collaborating pairs performed better than solitary searchers, search in the shared gaze condition was best of all: twice as fast and efficient as solitary search. People can successfully communicate and coordinate their searching labor using shared gaze alone. Strikingly, shared gaze search was even faster than shared-gaze-plus-voice search; speaking incurred substantial coordination costs. We conclude that shared gaze affords a highly efficient method of coordinating parallel activity in a time-critical spatial task.
