Principal Component Analysis (PCA) is a well-established technique in image processing and pattern recognition. Incremental PCA and robust PCA are two interesting problems with numerous potential applications. However, these two issues have only been separately addressed in the previous studies. In this paper, we present a novel algorithm for incremental(More)
Two dimensional windows based interfaces may not be appropriate for wearable computers. In this paper we draw on established virtual reality techniques to design and evaluate several alternate methods for information presentation in a wearable environment. We find simple body-spatialised displays provide benefits over traditional head-stabilised displays.(More)
marks a broad emerging trend in advanced human-computer interaction. Wearable computers— the next generation of portable machines, worn on the body—provide constant access to computing and communications resources. However, wide adoption of wearable computers first requires solving unique interface challenges. One of the most important is how to present and(More)
Inhabited television combines collaborative virtual environments (CVEs) with broadcast television so that on-line audiences can participate in television shows within shared virtual worlds. We describe a series of experiments with inhabited television, beginning with the NOWninety6 poetry performance, The Mirror, and Heaven & Hell—Live. These(More)
Inhabited TV combines collaborative virtual environments (CVEs) with broadcast TV so that on-line audiences can participate in TV shows within shared virtual worlds. Three early experiments with inhabited TV raised fundamental questions concerning the extent to which it is possible to establish fast-pace social interaction within a CVE and produce a(More)
Mark Weiser’s vision that ubiquitous computing will overcome the problem of information overload by embedding computation in the environment is on the verge of becoming a reality. Nevertheless today’s technology is now capable of handling many different forms of multimedia that pervade our lives and as a result is creating a healthy demand for new content(More)
INTRODUCTION Inhabited TV involves the public deployment of collaborative virtual environments (CVEs) so that on-line audiences can participate in TV shows within shared virtual worlds. This extends traditional broadcast TV and more recent interactive TV by enabling social interaction among participants and by offering them new forms of control over(More)
This paper presents a distributed virtual environment architecture targeted specifically at network games. It outlines the requirements for supporting a game genre known as graphical multi-user dungeons or dimensions, and shows how these requirements can be met by a novel approach to the distribution of the game environment model. An implementation of the(More)
