Caretta: Integration of Shared and Personal Spaces for Group Activity Support

摘要

In this paper, a system called Caretta that integrates personal and shared spaces to support face-to-face collaboration is described. We use PDAs and a multiple-input sensing board for personal and shared spaces, re-spectively. Users of Caretta can discuss and negotiate with each other in the shared space by manipulating physical objects, while they individually examine their ideas in their own personal spaces. Caretta allows users to participate in group activities interchangeably and seamlessly using both these spaces, and supports users in urban planning tasks. User studies to evaluate Caretta are described.
