The growing number of three-dimensional (3D) objects stored in digital libraries brought forth the challenge of search in 3D model collections. To address it, several approaches have been developed for 3D object retrieval. However, these approaches traditionally present query results as a list of thumbnails, and fail to take advantage of recent visualization and interaction technologies. In this paper,...
3D graphical interaction offers a large amount of possibilities for musical applications. However it also carries several limitations that prevent it from being used as an efficient musical instrument. For example, input devices for 3D interaction or new gaming devices are usually based on 3 or 6 degrees-of-freedom tracking combined with push-buttons or joysticks. While buttons and joysticks do not...
Immersive virtual environments (IVEs) allow participants to interact with their 3D surroundings using natural hand gestures. Previous work shows that the addition of haptic feedback cues improves performance on certain 3D tasks. However, we believe this is not true for all situations. Depending on the difficulty of the task, we suggest that we should expect differences in the ballistic movement of...
A fully-articulated visual representation of oneself in an immersive virtual environment has considerable impact on the subjective sense of presence in the virtual world. Therefore, many approaches address this challenge and incorporate a virtual model of the user's body in the VE. Such a "virtual body" (VB) is manipulated according to user motions which are defined by feature points detected...
One of the main focuses in immersive virtual environment research is traveling techniques. A traveling technique depends primarily on the tasks needed to be performed as well as the device(s) used to accomplish a given task. In this paper we examine the potential of a relatively new and inexpensive device introduced in the gaming industry that revolutionized the way 3D games are played. We developed...
