ViMiC (Virtual Microphone Control) is a new toolbox for real-time synthesis of spatial sounds, particularly for concert situations and sound installations, and especially for larger or non-centralized audiences. Based on the concept of virtual microphones positioned within a virtual 3D room, ViMiC supports loudspeaker reproduction up to 24 discrete loudspeaker channels whereby the loudspeakers ...

A real-time audio rendering system is introduced which combines a full room-specific simulation, dynamic crosstalk cancellation, and multitrack binaural synthesis for virtual acoustical imaging. The system is applicable for any room shape (normal, long, flat, coupled), independent of the a priori assumption of a diffuse sound field. This provides the possibility of simulating indoor or outdoor ...

We describe an algorithm for placing room contents including furniture and general clutter in a virtual environment according to design constraints specified in the form of a Petri net. We have implemented a prototype system and present images generated by it. The outputs of our prototype are believable, varied, random, yet controllable and structured room layouts suitable for video games.

We have set up a brain-computer interface to be used as an input device to a highly immersive virtual reality Cave-like system. We have carried out two navigation experiments: three subjects were required to rotate in a virtual bar room by imagining left or right hand movement, and to walk along a single dimension in a virtual street by imagining foot or hand movement. In this paper we focus on...

This mobile control interface was developed to nd an intuitive and e cient manner to interact with modular robots called Roombots. It is an iPad application that provides an augmented reality environment in order to interact with virtual 3D pieces of furniture made of Roombots. A user study was conducted to decide whether the ability to move inside the room and the use of augmented reality posi...

Digital immersive virtual environment technology (IVET) enables behavioral scientists to conduct ecologically realistic experiments with near-perfect experimental control. The authors employed IVET to study the interpersonal distance maintained between participants and virtual humans. In Study 1, participants traversed a three-dimensional virtual room in which a virtual human stood. In Study 2,...

This paper addresses the Semi-virtual Multidimensional Distance Learning System (SMDL), which is a technical, pedagogical, and organisational prototype-structure of a semi-virtual university. SDML includes both synchronous and asynchronous learning modes. During the initial stage of our project, we regularly transmitted a lecture from a specially equipped lecture room in one university to an eq...

In this paper we report on the navigation in a virtual environment by the output signal of an EEG-based Brain-Computer Interface (BCI). Such a BCI transforms bioelectrical brain signals, modified by mental activity into a control signal. At this time only 1-D or 2-D BCI feedbacks are used. The graphical possibilities of virtual reality (VR) should help to improve BCI-feedback presentations and ...
