Speaker’s pragmatic temporal voice range profile (TVRP) and F0 distribution histogram were used for comparing two radio speakers and two speaking styles in one speaker. It is assumed that the internal distribution of the temporal voice range, relative placement of the range on semitone scale and the concentration of F0 points in certain semitone classes of the F0 histograms are connected with t...

We present Save ‘Em, an augmented reality-based computer game designed to explore the universal challenge of making computer games more immersive, entertaining and fun. As in the classic computer game Lemmings, Save ‘Em is based on maneuvering a group of slow-witted characters called Dudes through a treacherous maze. Using augmented reality techniques, Save ‘Em places virtual game entities dire...

In the context of MRI-guided stereotaxy a new stereotaxic atlas of the human thalamus was developed in order to improve anatomical definition and precision in the prediction of the exact location of thalamic targets. It is based on multiarchitectonic parcellation (Nissl, myelin, calcium-binding proteins). Sagittal atlas data were digitized and registered together with 3D MRI data sets. In a coa...

A research testbed is described for exploring the automated layout of graphical displays. We address the problem of determining the size and position of the objects displayed to a user. Our approach is based on the graphic design concept of a design grid. A design grid is a set of proportionally-spaced vertical and horizontal lines that control the position and size of the objects being laid ou...

This paper presents the results of an exploratory qualitative study conducted with 26 consumers about their use of computer screen savers. The results show how the use of screen savers remains almost nonexistent. Unknown or taking too long to apply, this feature is not attractive to persons interviewed who do not use it for sustainable development purposes. The paper presents the results of thi...

For some years, our group at FX Palo Alto Laboratory has been developing technologies to support meeting recording, collaboration, and videoconferencing. This paper presents several systems that use video as an active interface, allowing remote devices and information to be accessed “through the screen.” For example, SPEC enables collaborative and automatic camera control through an active vide...

We studied the influence of visual feedback on the tactual perception of both speed and spatial period of a rotating texture. Participants were placed in a situation of perceptual conflict concerning the rotation speed of a cylindrical texture. Participants touched a cylindrical texture of gratings rotating around its axis at a constant speed, while they watched a cylinder without gratings rota...

besides being a recreational amusement, it also serves as an important function for the psychological, physiological and social development of a child. Children learn about themselves and the world and people around them; they develop and improve manifold and important skills, such as social competence, problem-solving and creativity. In contrast to traditional games, computer and video games t...

Internet studies researchers should consider how internet spectators are addressed and encouraged to engage. In this article, I offer some basic comments about internet spectatorship and present a detailed analysis of the ways in which spectatorship operates in the women's webcam form. Webcam spectators may have less control than they expect because women webcam operators exert authority and ac...

This research investigates the validity of the layout complexity metric to GUI screen design. This metric offers a simple method to gauge the complexity of the visual design of a computer screen by classifying screen objects into classes based on common dimensions and positions. However, though it has been used by other interface researchers, it is not clear that it is a valid metric for GUIs. ...
