Selectively canceling signals at specific locations within an acoustical environment with multiple listeners is of significant importance for home theater, automobile, teleconferencing, office, industrial and other applications. The traditional noise cancellation approach is impractical for such applications because it requires sensors that must be placed on the listeners. In this paper we inve...

Live theater is typically designed to alter the state of mind of the audience. Indeed, the perceptual inputs issuing from a live theatrical performance are intended to represent something else, and the actions, emphasized by the writing and staging, are the key prompting the adhesion of viewers to fiction, i.e., their belief that it is real.

But with this also gained access cultural or other practices that previously not part life. That resulted a detailed spectrum of participation from form listening-observing levels giving feedback taking control (for example putting questions pa...

But they must be effective to bring up the children’s cultivation of aesthetic sensitivity. And we have heard from teachers of elementary schools that most of themes of computer education in school are the operation of Painting Too...

The image generated by an off-center projector appears distorted (Figure 1, left). Using an uncalibrated camera pointed at the presentation screen, our system automatically recovers the projector-to-screen homography and pre-warps the computer output to produce a keystone-corrected image (Figure 1, right). This allows the presenter to place the microportable projector anywhere in the room witho...
