3-D sound field reproduction systems can provide listeners with a sense of presence. In this study, we have proposed the 3-D sound field localization system using parametric loudspeakers. This system can easily represent sound images on the wall by using parametric loudspeakers that have a high directivity. In contrast, it is difficult to reproduce reverberant environments such as a concert hal...

The architecture of circuital quantum computers requires computing layers devoted to compiling high-level algorithms into lower-level circuits gates. general problem is approximate any unitary transformation that describes the computation, as a sequence elements selected from finite base universal existence an approximating one qubit gates guaranteed by Solovay-Kitaev theorem, which implies sub...

As Biocca pointed out, the “two poles model“ of presence has only considered the virtual and pyshical spaces, but not the imaginary spaces. This work is aimed at comparing the sense of presence between virtual and imaginary environments. 100 participants were randomly assigned to one of the two conditions (imagined versus virtual spaces) and the subjective sense of presence was measured in thre...

We describe the ``WEDGE'' immersive projection theater. The WEDGE has been built as an affordable installation for university VR infrastructure in Australia. It achieves a ``semi-immersive'' sense of presence without, apparently, give rise to significant discomfort. The vertex region of the theater appears to be especially effective in giving a sense of presence. See http://wedge.anu.edu.au/ fo...
