When the pace of interaction with a task is too slow the user s execution evaluation loop is broken Feedback normally says what has happened However when the task is slow nothing has happened yet the interest shifts to what will have happened This poses two problems for the user Firstly recalling the appropriate context when a response eventually arrives Secondly maintaining the expectation tha...

A person-computer ensemble system is one of time-concerned cooperative systems, which performs secondo (the second part) in an ensemble played by a computer-controlled piano cooperating with primo (the leading part) played by a person performer. In the realtime performance, to determine which key is touched, or played, by the person performer, the matching algorithm between the score and the re...

Large-scale sensor networks are becoming more present in our life then ever. Such an environment could be a cellular network, an array of fire detection sensors, an array of solar receptors, and so on. As technology advances, opportunities arise to form large-scale cooperative systems in order to solve larger problems in an efficient way. As more large-scale systems are developed, there is a gr...

This paper presents our latest results in synthesizing high quality trumpet performances. Our approach identifies the continuous control over the sound as a fundamental element in the synthesis process. We developed our synthesis model as a cooperative system of two sub-models, continuous control parameters providing the interface between them. The two sub-parts are the instrument model, which ...
