Properly reacting to congestion is known to be a requirement for maintaining the stability of the Internet; in addition, UDP based applications should do so for their own sake if they are delay- or loss-sensitive. We measured the responsiveness of the three popular streaming media applications RealPlayer

. This paper presents analysis from an empirical study of the two dominant streaming multimedia products, RealNetworks RealPlayer ™ and Microsoft MediaPlayer™. Utilizing two custom media player measurement tools, RealTracker and MediaTracker, we are able to gather application layer and network layer

ABSTRACT Traditionally, virtual reality systems use 3D computer graphics to model and render virtual environments in real-time. This approach usually requires laborious modeling and expensive special purpose rendering hardware. The rendering quality and scene complexity are often limited because

predicted and actual outcomes, the new methods assign credit by means of the difference between temporally successive predictions. Although such temporal-difference methods have been used in Samuel's checker player, Holland's bucket brigade, and the author's Adaptive Heuristic Critic

. The responsiveness of commercial streaming media applications will play an important role in the network impact of streaming media. Unfortunately, there are few empirical studies that analyze the responsiveness, or lack of it, of current streaming media products. In this work, we measure the responsiveness of Real

We present data and argument to show that in Tetris-a real-time, interactive video game-certain cognitive and perceptual problems ore more quicktv, easily, and reliably solved by performing actions in the world than by performing com-putational actions in the head atone. We have found that some

Although player enjoyment is central to computer games, there is currently no accepted model of player enjoyment in games. There are many heuristics in the literature, based on elements such as the game interface, mechanics, gameplay, and narrative. However, there is a need to integrate

Abstract. This paper presents algorithms for the automatic synthesis of real-time controllers by nding a winning strategy for certain games de ned by the timed-automata of Alur and Dill. In such games, the outcome depends on the players ' actions as well as on their timing. We believe
