Text presented in lecture halls often simultaneously appears on multiple visual displays (e.g., blackboards, projection screens, video monitors), which should be legible to the entire audience seated in an ideal viewing area. Existing guidelines identify this area as fanshaped, but the origin of those guidelines and the data on which they are based are not specified. To supplement the guideline...

This paper presents an evaluation of the benefits and user acceptance of a multimodal interface in which the user interacts with a game-like interactive virtual reality application ‘‘The Enigma of the Sphinx’’. The interface consists of a large projection screen as the main display, a ‘‘magic wand’’, a stereo sound system and the user’s voice for ‘‘casting spells’’. We present our conclusions c...

In this paper we describe a prototype system for directing a computer generated scene for film planning. The system is based upon the concepts of the Intuitive Interface, an environment in which the user interacts in front of a projection screen, and where interaction in physical space and pointing gestures are used to direct the scene. The environment demands certain requirements of the intera...

An Invisible Line is an installation focusing on the remote communication between 2 human users, based on the analysis of full-body expressivity. It aims at creating shared, networked, social experiences. It is the result of a scientific and artistic collaboration between Casa Paganini InfoMus Lab (Genova, Italy), IRCAM (Paris, Italy) and The Hochschule für Musik und Theater (Hamburg, Germany)....

An Interactive Whiteboard (IWB) is a device that is a giant tactile and projection screen. It can be considered as one of the main elements for pedagogical innovation with information technology. IWB allows to transform the classical classroom environment into a working and learning interactive environment. This pedagogical tool is particularly pertinent in higher school especially in scientifi...

The Volume Slicing Display is a device enabling the interactive exploration of volumetric data (e.g. medical images) using a piece of Plexiglass or paper that functions both as a control interface and as a passive, untethered projection screen. With the VSD, radiologists would be able to retrieve a certain amount of three-dimensionality from a flat X-ray plate at any time, by just touching cert...

Many usability problems are associated with navigation and exploration of virtual space. In an attempt to find methods that support navigation within virtual space, this paper describes an investigation of cinematography conventions. In particular, this will focus on conventions that suggest to spectators the existence of additional space other than that contained within the confines or borders...

This paper presents a system that supports the exploration of digital representations of large-scale museum artifacts in through non-instrumented, location-based interaction. The system employs a state-of-the-art computer vision system, which localizes and tracks multiple visitors. The artifact is presented in a wall-sized projection screen and it is visually annotated with text and images acco...

We present a novel walk-through 3D display based on the patented FogScreen, an “immaterial” indoor 2D projection screen, which enables high-quality projected images in free space. We extend the basic 2D FogScreen setup in three major ways. First, we use head tracking to provide correct perspective rendering for a single user. Second, we add support for multiple types of stereoscopic imagery. Th...
