Building Virtual and Augmented Reality museum exhibitions

Abstract: A system that allows museums to build and manage Virtual and Augmented Reality exhibitions based on 3D models of artifacts is presented. Dynamic content creation based on pre-designed visualization templates allows content designers to create virtual exhibitions very efficiently. Virtual Reality exhibitions can be presented both inside museums, e.g. on touch-screen displays installed inside galleries and, at the same time, on the Internet. Additionally, the presentation based on Augmented Reality technologies allows museum visitors to interact with the content in an intuitive and exciting manner.

Automatic focus improvement for augmented reality displays

Abstract: An augmented reality system provides improved focus of real and virtual objects. A see-through display device includes a variable focus lens a user looks through. A focal region adjustment unit automatically focuses the variable focus lens in a current user focal region. A microdisplay assembly attached to the see-through display device generates a virtual object for display in the user's current focal region by adjusting its focal region. The variable focus lens may also be adjusted to provide one or more zoom features. Visual enhancement of an object may also be provided to improve a user's perception of an object.

ARQuake: the outdoor augmented reality gaming system

Abstract: cially available affordable wearable computers and head-mounted displays (HMDs), it is possible to develop augmented reality entertainment applications suitable for an outdoor environment. We extended an existing desktop game and developed it into the ARQuake system [4], one of the first systems that allows users to play augmented reality games outdoors—allowing them to move in the physical world, and at the same time experience computer-generated graphical monsters and objects. The game we extended was Quake from id Software (see www.idsoftware.com), a firstperson-perspective, shoot-em-up game initially released in 1996. In Quake, the player runs around a virtual world, shooting at monsters, collecting objects, and completing objectives. The game is desktop-based, with the user interacting with it using a monitor, keyboard, and mouse. Although the game is relatively old, the graphics engine is very powerful and runs on a wide range of computing hardware. Recently, id Software released the source code for Quake, making it possible for enthusiasts and researchers to modify the game for their own purposes. Augmented reality (AR) is the process of overlaying and aligning computer-generated images over a user’s view of the physical world. Using a transparent HMD placed on the user’s head, an internal half-silvered mirror combines images from an LCD display with the user’s vision of the world (see Figure 1). By combining this display technology with a wearable computer, it is possible for the user to walk outdoors and visualize graphical objects that are not normally visible. A comprehensive survey article [1] discusses most aspects of this research area. Wayne Piekarski and Bruce Thomas

Evaluating the benefits of augmented reality for task localization in maintenance of an armored personnel carrier turret

Abstract: We present the design, implementation, and user testing of a prototype augmented reality application to support military mechanics conducting routine maintenance tasks inside an armored vehicle turret. Our prototype uses a tracked head-worn display to augment a mechanic's natural view with text, labels, arrows, and animated sequences designed to facilitate task comprehension, location, and execution. A within-subject controlled user study examined professional military mechanics using our system to complete 18 common tasks under field conditions. These tasks included installing and removing fasteners and indicator lights, and connecting cables, all within the cramped interior of an armored personnel carrier turret. An augmented reality condition was tested against two baseline conditions: an untracked headworn display with text and graphics and a fixed flat panel display representing an improved version of the laptop-based documentation currently employed in practice. The augmented reality condition allowed mechanics to locate tasks more quickly than when using either baseline, and in some instances, resulted in less overall head movement. A qualitative survey showed mechanics found the augmented reality condition intuitive and satisfying for the tested sequence of tasks.

A comprehensive survey of augmented reality assembly research

Abstract: In the past two decades, augmented reality (AR) has received a growing amount of attention by researchers in the manufacturing technology community, because AR can be applied to address a wide range of problems throughout the assembly phase in the lifecycle of a product, e.g., planning, design, ergonomics assessment, operation guidance and training. However, to the best of authors’ knowledge, there has not been any comprehensive review of AR-based assembly systems. This paper aims to provide a concise overview of the technical features, characteristics and broad range of applications of AR-based assembly systems published between 1990 and 2015. Among these selected articles, two thirds of them were published between 2005 and 2015, and they are considered as recent pertinent works which will be discussed in detail. In addition, the current limitation factors and future trends in the development will also be discussed.
