Abstract

Aggregate pointers, a new type of telepointer, can be used to support the collaboration of many people in interactive environments. An aggregate pointer can make it easy for people to understand the overall direction of others' intentions or interests, and help achieve a group decision or build consensus. Moreover, aggregation can make distracting behavior or noise less disruptive. Aggregate pointers prevent such problems from disturbing collaborative work. We conducted experiments to show that people are not good at accurately locating the focus that is reflected by multiple telepointers, and that aggregate pointers help people share more accurate aggregation and complement individual telepointers.
