Pacers: time-elastic objects
Steven H. Tang,Mark A. Linton +1 more

- pp 35-43
TL;DR: This paper introduces an object called a Pacer that is “timeelastic” in that it can adjust the quality of its presentation according to the amount of time available and can automatically degradation quality depending on the user’s input rate and the speed of the rendering system.

Abstract: Current time-based presentation systems are rigid in that they assumethe running time of all components of a presentation is constant Furthermore, most systems offer little or no supportfordynamically adapting the presentation quality to the (lack of) available system resources In this paper, we introduce an object called a Pacer that is “timeelastic” in that it can adjust the quality of its presentation according to the amount of time available We have implemented a direct manipulation graphical interface using pacersthat can automatically degradepresentation quality in a controlled fashion depending on the user’s input rate and the speed of the rendering system

Lottery and stride scheduling: flexible proportional-share resource management
Carl A. Waldspurger,William E. Weihl +1 more
- 01 Jan 1995
TL;DR: In this article, the authors present flexible abstractions for specifying resource management policies, together with efficient mechanisms for implementing those abstractions, including both randomized and deterministic algorithms that provide proportional-share control over resource consumption rates.

The Hyperbolic Browser : A Focus 1 Context Technique for Visualizing Large Hierarchies
J Onh L Amping,R Amana R Ao +1 more
- 01 Jan 1996
TL;DR: In this paper, a new focus context technique based on hyperbolic geometry for visualizing and manipulating large hierarchies is presented. But the technique assigns more display space to a portion of the hierarchy while still embedding it in the context of the entire hierarchy.
