Interaction with mobile applications is often awkward due to the limited and miniaturized input modalities available. This is especially problematic for games where the only incentive to use an application is the pleasure derived from the interaction. It is therefore interesting to examine novel forms of interaction in order to increase the "playability" of mobile games.In this paper we present a simple mobile gaming application on a standard Pocket PC PDA that employs computer vision (CV) as it's main interaction modality. Practical experience with the application demonstrates the feasibility of CV as a primary interaction modality and indicates the high potential of CV as an input modality for mobile devices in the future. Our approach exploits the video capabilities that are becoming ubiquitous on camera equipped smart-phones and PDAs to provide a fun solution for interaction tasks in games like "Pong", "Break-out" or soccer.
This article introduces and discusses issues in the design of user interfaces for visually impaired people in the domain of virtual communities. We begin by pointing out that collaborative virtual environments provide additional means for visually impaired people which may help to accomplish a better integration into existing communities and social activities. We give a short introduction to the way visually impaired people usually work with a PC and show how their method of information access differs to sighted people. We then take a look at the advantages and disadvantages of existing adaptations to operating systems. Based on this analysis we describe some requirements for user interfaces of groupware and chat applications which enhance the usability for visually impaired people without losing the attractiveness and intuitiveness for the sighted. We finally describe a prototype of a special IRC-Client, called BIRC, and discuss its advantages and limitations.

Specific radiological requirements have to be considered for realization of telemedicine. In this article the goals and requirements for an extensive implementation of teleradiology are defined from the radiological user's point of view. Necessary medical, legal and professional prerequisites for teleradiology are presented. Superior requirements, such as data security and privacy or standardization of communication, must be realized. Application specific requirements, e. g. quality and extent of teleradiological functions as well as technological alternatives, are discussed. Each project must be carefully planned in relation to one's own needs, extent of functions and system selection. Topics like legal acceptance of electronic documentation, reimbursement of teleradiology and liability must be clarified in the future.
We describe a framework that allows to easily design and implement virtual and augmented reality worlds. Based on a structured design approach for interactive animated 3D conten we want to supply designers and content experts of complex virtual environments with a component based to olset for the structured design of the visual and abstract components of 3D applications. KeywordsVirtual and Augmented Reality, Design Framework, Interactive 3D Animation. 1o INTRODUCTIONRecent advances in 3D computer graphics have allowed application developers to integrate .animated 3D graphics in their work without being burdened by low level details. While technical advances have laid the foundation for wide spread use of interactive 3D [24], there is still a significant lack of design experience and dedicated tools that would allow a seamless integration of interactive 3D components in cunent multimedia applications. Most often the development of 3D content requires an ad-hoc realisation that is implemented from scratch resulting in unacceptable development costs.To address these problems we are concerned with the structured design of interactive animated 3D content. An important point is the applicability of our approach in a wide range of application areas (multimedia / 3D / VR / AR) and hardware/software configurations ranging from mobile devices over standard PCs to graphics super computers and parallel processing architectures. Moreover, we want to support content expert users (i.e. designers) and not only technical experts (i.e, 3D programmers). Current application areas include interactive 3D illustrations of technical systems, animated 3D user interfaces and the visualization of simulation results. It is our aim to provide content experts with a methodology and a corresponding toolset that supports a high level design view of the application and at the same time allows of VPJAR Content designers to have fine control over their creation.Based on previous experiences in tool support for interactive 3D worlds, e.g.[19,S], we have developed i4D, a framework for the structured design of animated VR/AR content based on reusable elements (components) that can be used in a large number of applications. Our approach extends a design methodology with high level tools for the design of visual 3D components. The concepts and tools have been validated in a number of relevant application scenarios. DESIGN OF INTERACTIVE VR / AR CONTENTA previous study of 3D development projects in the education domain identified a number of ke -problems in the design and development of interactive 3D content [2,3] , The lack of an appropriate conceptual model hinders the design process and renders the communication between stakeholders in the design process difficult. Conceptual design tools adopted from conventional media design (e.g. storyboards) fail to address the special requirements of viewer interaction and dynamic content.• The lack of a structured design process makes it difficult for designers and developers to bridge the large conceptual ga...
