Figure 1: The textual Web interface versus the WORDGRAPH visualization of the NETSPEAK writing assistant. NETSPEAK helps writers in choosing words while writing a text. It checks for the commonness of phrases and allows for the retrieval of alternatives by means of wildcard queries. To support such queries, we implement a scalable retrieval engine, which returns high-quality results within milliseconds using a probabilistic retrieval strategy. The results are displayed as WORDGRAPH visualization or as a textual list. The graphical interface provides an effective means for interactive exploration of search results using filter techniques, query expansion and navigation. Our observations indicate that, of three investigated retrieval tasks, the textual interface is sufficient for the phrase verification task, wherein both views support context-sensitive word choice, and the WORDGRAPH best supports the exploration of a phrase’s context or the underlying corpus. The preferred view for context-sensitive word choice seems to depend on query complexity (i.e. the number of wildcards in a query).
Design Issues for Virtual Reality Systems
- Presented at the First Eurographics Workshop on Virtual Environments
, 1993
"... In this paper we describe a number of issues which are central to the design of a software architecture for a distributed, generic, virtual reality system. These include support for diverse and demanding applications, the management of time to provide high-quality interaction with tightly controlled ..."

Virtual reality system for industrial training
- In: Proceedings of 2007 IEEE International Symposium on Industrial Electronics
, 2007
"... Abstract-In this paper, a Virtual Reality Training system for maintenance of industrial equipment is presented. Since equipment are usually designed with CAD tools, it is feasible to create the Virtual Reality model. Despite of the virtual reality system itself, seting up an industrial related trai ..."

is overviewed to stress the compatibility of the system with other similar Virtual Reality systems. The software provides realistic virtual actors as well as sets of applicable high-level actions in real-time. Related issues on obtaining actor models and animating them in realtime are presented. We also
