Puppeteer takes advantage of the component-based nature of the applications to perform adaptation without modifying the applications. We illustrate the power of Puppeteer by demonstrating adaptations that would otherwise require significant modifications to the application. Our initial prototype supports Microsoft PowerPoint and Internet Explorer~5 without requiring any changes to the applications. It supports delayed data and image transmission as well as progressive image refinement. We measure our system's effectiveness with a large number of PowerPoint documents and Web pages. We measure user-perceived latencies for a variety of adaptation policies and over a variety of different network bandwidths. Our results show that Puppeteer can achieve average reductions in user latency of up to 84.22% for PowerPoint documents loaded over a 384~Kb/sec link and 76.42% for HTML documents loaded over 56~Kb/sec link.14 ppengYou are granted permission for the noncommercial reproduction, distribution, display, and performance of this technical report in any format, but this permission is only for a period of forty-five (45) days from the most recent time that you verified that this technical report is still available from the Computer Science Department of Rice University under terms that include this permission.
