ABSTRACT We report results of an auditory navigation experiment. In auditory navigation sound is employed as a navigational aid in a virtual environment. In our experiment, the test task was to find a sound source in a dynamic virtual acoustic environment. In dynamic auralization the movements of the subject are taken into account in acoustic modeling of(More)
In this paper, we introduce and analyze four gesture-controlled musical instruments. We briefly discuss the test platform designed to allow for rapid experimentation of new interfaces and control mappings. We describe our design experiences and discuss the effects of system features such as latency, resolution and lack of tactile feedback. The instruments(More)
The uncanny valley hypothesis, proposed already in the 1970s, suggests that almost but not fully humanlike artificial characters will trigger a profound sense of unease. This hypothesis has become widely acknowledged both in the popular media and scientific research. Surprisingly, empirical evidence for the hypothesis has remained inconsistent. In the(More)
We present a general methodology to produce synchronized soundtracks for animations. A sound world is modeled by associating a characteristic sound for each object in a scene. These sounds can be generated from a behavioral or physically-based simulation. Collision sounds can be computed from vibrational response of elastic bodies to the collision impulse.(More)
We present a survey of the current generation of 3D user interface (3DUI) applications, their developers, and development issues. 3DUI developing experiences from 71 developers – as well as information about 56 unique 3DUI applications – were collected and analysed. The statistics presented in this paper give a broad view over the 3DUI field and indicate(More)
A navigation test was carried out in a spatially immersive virtual environment. The test was a gamelike experience where the task of subjects was to find as many gates as possible while they navigated through a track guided by auditory and/or visual cues. The results are presented as a function of the number of found gates, searching times, and normalized(More)
