A Case Study in the Specification and Analysis of Design Alternatives for a User Interface

There is considerable interest within the Human Computer Interaction (HCI) community in the use of media spaces to enhance awareness and interaction between workers in offices or other spatially distributed environments. In addition to the technical challenges of providing reliable and efficient audio-visual communication, there are important social questions, in particular how users are able to control access to their personal environments, and how to advise other users about their level of availability. Within AMODEUS-2¹, an ESPRIT Basic Research Action concerned with the development, transfer and assessment of techniques for modelling human-computer interaction, a prototype media space has been analysed by various user and system oriented modelling techniques. This paper describes how formal specification can be used to express requirements on the interfaces needed to control access and availability in a media space. Beyond its obvious use in clarifying the subtle relationship between these concerns, the paper describes how the specification assists in assessing design options originating from other modelling disciplines.

Scene-Graph-As-Bus: Collaboration between Heterogeneous Stand-alone 3-D Graphical Applications

We describe the Scene-Graph-As-Bus technique (SGAB), the first step in a staircase of solutions for sharing software components for virtual environments. The goals of SGAB are to allow, with minimal effort, independently-designed applications to share component functionality; and for multiple users to share applications designed for single users.This paper reports on the SGAB design for transparently conjoining different applications by unifying the state information contained in their scene graphs. SGAB monitors and maps changes in the local scene graph of one application to a neutral scene graph representation (NSG), distributes the NSG changes over the network to remote peer applications, and then maps the NSG changes to the local scene graph of the remote application. The fundamental contribution of SGAB is that both the local and remote applications can be completely unaware of each other; that is, both applications can interoperate without code or binary modification despite each having no knowledge of networking or interoperability.     

Society Supports Software Engineering PE Examination

The IEEE Computer Society, in conjunction with the IEEE-USA, recently announced its partnership with the National Council of Examiners for Engineering and Surveying in support of establishing a Principles and Practice of Engineering examination for the software engineering discipline. Other topics include the election of editors in chief for 2011-2013 terms and the appointment of four EICs for CS transactions
