Exact test is introduced that uses real-time collision detection for both hand-and-tool and tool-and-object interactions. Chopsticks are adopted for one of the trials of our technique; although they have a very simple shape, they do have multiple functions. Here, a virtual object is manipulated by the virtual chopsticks, which are used by the motion of a user's hand captured by a hand gesture input device. Exact interaction is applied between the hand and chopsticks based on correct table manners. Experimental results demonstrate the effectiveness of the proposed multiple exact interactions, especially for precise object alignment tasks.","PeriodicalId":175913,"journal":{"name":"Proceedings IEEE Virtual Reality (Cat.

The haptic interface enables an artist to use a natural painting style while creating a texture. It avoids the traditional difficulty of mapping between the 2D texture space and the 3D model space by using parametric information available from our haptic tracing algorithm. The system maps user movement in 3D to movement in the 2D texture space and adaptively resizes the paintbrush in texture space to create a uniform stroke on the model.","PeriodicalId":175913,"journal":{"name":"Proceedings IEEE Virtual Reality (Cat.

Meeting this promise, however; has proven to be difficult, as the interface between the user and the computer is not complete, the metaphors for interacting with information are not always obvious, and the tools for including current interaction techniques are not sufficient to the task. We present SVIFT, the Simple Virtual Interactor Framework and Toolkit, which supports efforts to meet the interaction needs of immersive VE applications. SVIFT allows for the design and implementation of various interaction techniques that can be easily incorporated into many VE applications and combined with other interaction techniques to produce more complex interactions. We also discuss the differences between desktop and immersive environment interaction, and the implications of those differences on the design of an interactor framework.","PeriodicalId":175913,"journal":{"name":"Proceedings IEEE Virtual Reality (Cat.

Behringer","doi":"10.1109/VR.1999.756958","DOIUrl":"https://doi.org/10.1109/VR.1999.756958","url":null,"abstract":"Registration for outdoor systems for Augmented Reality (AR) cannot rely on the methods developed for indoor use (e.g., magnetic tracking, fiducial markers). Although GPS and the earth's magnetic field can be used to obtain a rough estimate of position and orientation, the precision of this registration method is not high enough for satisfying AR overlay. Computer vision methods can help to improve the registration precision by tracking visual clues whose real world positions are known. We have developed a system that can exploit horizon silhouettes for improving the orientation precision of a camera which is aligned with the user's view. It has been shown that this approach is able to provide registration even as a stand-alone system, although the usual limitations of computer vision prohibit to use it under unfavorable conditions. This paper describes the approach of registration by using horizon silhouettes. Based on the known observer location (from GPS), the 360 degree silhouette is computed from a digital elevation map database. Registration is achieved, when the extracted visual horizon silhouette segment is matched onto this predicted silhouette. Significant features (mountain peaks) are cues which provide hypotheses for the match. Several criteria are tested to find the best matching hypothesis. The system is implemented on a PC under Windows NT. Results are shown in this paper.","PeriodicalId":175913,"journal":{"name":"Proceedings IEEE Virtual Reality (Cat.
