This paper discusses the development of a gestural controller interface for contemporary vocal performance and electronic processing called the eMic (extended Mic-stand interface controller). This instrument is a modified microphone stand, custom fitted with an array of sensors and gesture capturing devices aimed at capturing commonly used gestures and movements of vocal performers who use micr...

Think Aloud is cost effective, promises access to the user’s mind and is the applied usability technique. But ”keep talking” is difficult, besides, the multimodal interface is visual not verbal. Eye-tracking seems to get around the verbalisation problem. It captures the visual focus of attention. However, it is expensive, obtrusive and produces huge amount of data. Besides, eye-tracking do not ...

The simulation of two-phase flow problems involving two time-dependent spatial regions with different physical properties is computationally hard. The numerical solution of such problems is complicated by the need to represent the movement of the interface. The level set approach is a front-capturing method representing the position of the interface implicitly by the root of a suitably defined ...

Abstract. Flows with violent free-surface motions occur in several problems in hydrodynamics, such as fuel or water sloshing in tanks, waves breaking in ships, offshore platforms, harbors and coastal areas. The computation of such highly nonlinear flows is challenging since free-surfaces commonly present merging, fragmentation and breaking parts, leading to the use of interface capturing Euleri...

Dendritic solidification of pure materials from an undercooled melt is studied using the extended finite element method/level set method for modelling the thermal problem and a volume-averaged stabilized finite element formulation for modelling fluid flow. The extended finite element method using evolving enrichment functions allows accurate modelling of the discontinuous thermal conditions at ...

The advantage of front tracking over capturing methods for the numerical simulation of discontinuity surfaces in fluid flow is to eliminate the numerical diffusion of mass across a fluid interface. For accurate modeling of an interface between miscible fluids, however, physical mass diffusion may be significant, and must be added to the calculation. The main purpose of this paper is to introduc...

A new method is presented for numerically capturing a moving interface of arbitrary dimension and codimension. The method is named the ‘local level set method’, since it localizes the level set method near the interface to significantly reduce the computational expense of the level set method. Following the framework of the level set method, an interface is implicitly represented as the zero le...

The advent of mobile, wearable, and ubiquitous computing presents opportunities for audiocentric interfaces that use sound as the primary or only means of displaying information to users whose eyes are otherwise engaged. While interface designers have a wealth of technological capabilities at their disposal for capturing, storing, transmitting, and displaying sound, there is a lack of appropria...
