摘 要：Although large wall-sized displays are becoming increasingly available, their rate of adoption in research and business environments has been limited due to the high cost of developing applications that scale to cluster-driven displays and lack of interaction techniques for multi-user input on such shared displays. In this report, we introduce Hydrascope, a framework for creating multi-viewmeta-applicationsfor cluster-driven displays by adapting existing web applications without modifying their source code. Hydrascope meta-applications work by running multiple instances of an application in parallel and synchronizing their views. We demonstrate the capabilities of our framework with five example applications.
