NASA’s Hyperwall (Sandstromet. al., 2003) has a 64-megapixel Tiled Display Wall comprising 49 monitors (7 monitors horizontal × 7monitors vertical). LambdaVision uses 55 monitors (11 monitors horizontal × 5 monitors vertical) and buildsa 100 megapixel high-resolution tiled display wall system. They also propose middleware for tiled displaywalls called SAGE (Renambot et. al., 2003) An extremely large tiled display wall is HIPerSpace (DeFantiet.al. 2009) used at the University of California, San Diego. Altogether, it has a 225-megapixel display.Details of existing tiled display wall systems were surveyed by Ni et. al.(2006).Those systems aim at performance and resolution for application to scientific visualization for life sciencedata and ultra-high-resolution satellite images. Apparently, research issues related to tiled display wall havebypassed consumer applications in favor of improving scientific high-performance computing. Consequently,such applications require the use of expensive high-end machines, complex settings and elaborateprogramming. However, in explosive growth of web technologies, ultra-high-resolution satellite images, e.g.Google Maps, via web browser are becoming increasingly available, and are valued by many users.In other words, high-resolution visualization is no longer for scientists only: ordinary people can haveaccess to it. For that reason, we propose a low-cost tiled display wall, WDiM, which consists of low-endmachines and which is based solely on web technologies.Additionally, we must point out that WDiM uses only web programming language. Numerous skillfulweb developers and programmers are working today who can create WDiM applications.7. CONCLUSIONSAs described in this paper, we propose WDiM, a method to display high-resolution web applications on atiled display wall. We also express the design of low-cost tiled display wall made of low-end consumerdevices. Additionally, we presented an example of a high-resolution web application which renders to thetiled display wall. This paper explained how to decompose high-resolution web applications implemented tocompose distributed web services and APIs.Future research in this area will be undertaken to attempt browser-to-browser communication using a newversion of the Opera browser and vector rendering using HTML5. We believe that decomposable highresolutionweb applications are a novel model of next-generation web usage.REFERENCESDeFanti T. et al, 2009.
