Abstract:Health-care professionals have a broad range of needs for information and cooperation while working at different points of care (e.g., outpatient departments, wards, and functional units such as operating theaters). Patient-related data and medical knowledge have to be widely available to support high-quality patient care. Furthermore, due to the increased specialization of health-care professionals, efficient collaboration is required. Personal mobile information tools have a considerable potential to realize almost ubiquitous information and collaborative support. They enable to unite the functionality of conventional tools such as paper forms, dictating machines, and pagers into one tool. Moreover, they can extend the support already provided by clinical workstations. An approach is described for the integration of mobile information tools with heterogeneous hospital information systems. This approach includes identification of functions which should be provided on mobile tools. Major functions are the presentation of medical records and reports, electronic mailing to support interpersonal communication, and the provision of editors for structured clinical documentation. To realize those functions on mobile tools, we propose a document-based client-server architecture that enables mobile information tools to interoperate with existing computer-based application systems. Open application systems and powerful, partially wireless, hospital-wide networks are the prerequisites for the introduction of mobile information tools.
Motivated by the widespread of file and video streaming over peer-to-peer networks, we propose to investigate the design of a peer-to-peer solution for image-based remote walkthrough. Due to the fact that our scheme relies on images to provide the user with interactive virtual environments, even thin mobile devices can benefit from image-based rendering's lower graphics power demand when compared to geometry rendering. The main objective of this paper is to present our remote walkthrough system and discuss a simple peer-to-peer distribution algorithm. Similar to peer-to-peer networked virtual environment solutions, our approach involves discovering neighboring peers using region of interest, instead of proximity of peer nodes. The main idea is that closer virtual users will have higher probability for sharing images, as they are navigating in the same region. We also discuss our previous buffering and scheduling mechanisms and how they work in a peer-to-peer environment. We also discuss our simulation experiments in order to evaluate the performance of our approach.
In order to utilize 3D image-based rendering technology on mobile devices, an efficient local buffer management schema is required to cope with the large set of data used by imagebased rendering algorithms, communication errors, communication latency, and virtual movements of the user. In this paper, we present a robust mechanism for managing a local reference image buffer on mobile devices. Our proposed technique is generic because we do not put any restrictions on the actual rendering algorithm. Experiment results show that the proposed technique is robust toward communication errors.
