This paper describes an audio-visual performance system based on real-time fluid simulation. The aim is to provide a rich environment for works which blur the boundaries between dance and instrumental performance – and sound and visuals – while maintaining transparency for audiences and new performers. The system uses infra-red motion tracking to allow performers to manipulate a real-time fluid...

Visual performance with a large video projection screen is popular for various entertainment events such as DJ events.

Four dimensions of thoughts—salience, polarity, originality, and emotionality—were analyzed. Results showed that redundancy had main effects on all four dimensions, whereas arousing visuals affected two. It is argued that the introduction of emotion...

What is the function of visuals in the design of an augmented keyboard performance device with projection? We address this question by thinking through the impact of design choices made in three examples on notions of locus of attention, visual anticipation and causal gestalt to articulate a space of design factors. Visuals can emphasize and deemphasize aspects of performance and help clarify t...

1. Challenges of Using Multimedia In the last decade, advanced computer technology has allowed for development of information systems and learning environments that combine language with other forms of human communication in innovative ways. Language in the form of written texts, for example, can be combined not only with static pictures or graphs as in printed material, but also with animation...

The present study investigates the central concerns of the use of visuals within the four EFL textbooks taught at Iranian high schools which have been prescribed by the Ministry of Education. To do this, the four EFL textbooks were evaluated and analyzed. Descriptive statistics were used to analyze data quantitatively. The analysis indicated that over the four textbooks, 95.71 percent of all vi...
