This paper presents a prototype for information visualization in an Augmented Reality environment. The prototype allows users to perform common tasks in desktop information visualization tools, such as data dynamic filters, attribute selection, semantic zoom and details on demand. Such tasks are seldom available in AR environments. We used a customized(More)
