摘要：Many recent studies of distributed-display environments discuss how to augment large workspaces with mixed reality technology. In addition to overcoming the difficulty of directly touching virtual objects located where a user cannot touch them in such large space environments, the usability of a distant access interface, which determines the total usability of the hard-to-reach objects, is the key issue in these studies. In this paper, we first discuss the metaphor of a shadow cast by a user's palm and extend it to a media as a user interface in augmented environments. Then, we introduce a new intuitive accessing method using hand gestures by image recognition. The proposed system, PALMbit-Silhouette , provides a distant user interface that enables a user to move an icon among distributed large displays with natural grasp-and-release gestures. Experiments with a prototype system showed that it enabled users to interact seamlessly with virtual objects in distributed-display environments.
