Mixed reality is one of the most important techniques to achieve the vision of ubiquitous computing. Traditional middleware for mixed reality provide high level abstraction to hide complex algorithms for analyzing video images, but applications programmers still need to take into account distribution and automatic reconfiguration when developing mixed reality applications for ubiquitous computing.Our middleware infrastructure hides all the complexities to build mixed reality applications for ubiquitous computing. Therefore, the development does not require advanced skills for ubiquitous computing. The paper describes the design and implementation of our infrastructure, and presents some scenarios and the current status showing its effectiveness.
The paper describes design and implementation of software infrastructure for building augmented reality applications for ubiquitous computing environments. Augmented reality is one of the most important techniques to achieve the vision of ubiquitous computing. Traditional toolkits for augmented reality provide the high level abstraction that makes it easy to build augmented reality applications. However, the applications programmers need to contemplate distribution and context-awareness that make the development of applications very hard, but they are necessary to build ubiquitous computing environments. Our infrastructure provides the high level abstraction and hides distribution and context-awareness from programmers. Therefore, the cost to develop augmented reality applications will be reduced dramatically by using our middleware infrastructure.
Abstract.A software platform for developing future information appliances requires to satisfy various diverse requirements. The operating system architecture presented in this paper enhances the flexibility and dependability through virtualization techniques. The architecture allows a system to use multiple operating systems simultaneously, and to use multi-core processors in a flexible way. Also, dependability mechanisms in our architecture will avoid crashing or hanging a system as much as possible in order to improve the user experience when defects in the software are exposed. We present a brief overview of each component in the operating system architecture and some sample scenarios that illustrate the effectiveness of the architecture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
