Virtual, Mixed, and Augmented Survey - Germany
Abstract
Augmented Reality (AR) and Virtual Environments (VE) have been introduced in the late 80s as innovative systems for displaying synthetic, computer-generated environments as if they were real. Various possible applications were identified soon, for instance: Product design, architecture, training, or teleoperation. But it turned out that computers rendering power and display technology were too limited for a reasonable application then. The whole concept seemed to be a promising science-fiction topic that had come up too early for realization and practical use. Nonetheless, technology evolved much faster. Less than a decade later, systems were powerful enough for first sample applications. Due to the huge demands on computing and rendering power (and resulting high financial expenses) they were just a small number of institutions doing research in this area. But again, it took only a short time until low-cost alternatives became available. The user community became much broader and, consequently, research and application activities were spread and intensified. But while computing, rendering, and display technologies have made tremendous advance the design of the human-system-interface (HSI) did not. As a matter of fact, most systems still have to be run by special trained, qualified personnel, and most applications are often limited to passive presentations. The systems interfaces are often prototypic and adapted from conventional two-dimensional graphical humancomputer- interfaces. Interfaces remain limited to an extension of existing concepts without exploiting their real potential. A better integration of new concepts for training, for system design and for other future applications by including the capabilities of systems in an early conceptual stage would be desirable. For this, the HSI has to be ergonomically designed on different levels, including the pragmatic, semantic, syntactic, and even lexical level.
