A Gesture-Based Interface for Seamless Communication between Real and Virtual Worlds
نویسندگان
چکیده
This paper proposes a gesture-based direct manipulation interface that can be used for data transfer among informational artifacts. “Grasp and Drop (Throw)” by hand gestures allows a user to grasp an object on a computer screen and drop (throw) it on other artifacts without touching them. Using the interface, a user can operate some artifacts in the mixed reality world in a seamless manner, and learn this interaction style easily. Based on this interaction technique, we developed a prototype of presentation system using Microsoft PowerPoint, a wall size screen, computer screens and a printer. The presentation system with gestures allows a presenter to navigate through PowerPoint slides and transfer a slide from one computer screen to another. We conducted an experiment which evaluate the interaction style of gestures and analyzed the user's satisfaction with a questionnaire. The result shows that the overall mean of successful recognition is 96.9 %, and the learning of the system is easy.

While virtual worlds have evolved to provide a good medium for social communication, they are very primitive in their social and affective communication design. The social communication methods within these worlds have progressed from early text-based social worlds, e.g. MUDS (multi-user dungeons) to 3D graphical interfaces with avatar control, such as Second Life. Current communication methods...

This paper advocates a new metaphor for designing threedimensional Augmented Reality (AR) applications, Tangible Augmented Reality (Tangible AR). Tangible AR interfaces combine the enhanced display possibilities of AR with the intuitive manipulation and interaction of physical objects or Tangible User Interfaces. We define what Tangible AR interfaces are, present some design guidelines and prot...
