the task. They are customizable in that they enable the users to adapt the retargetting function which maps their input onto the robot. Our studies support the advantages of such interfaces, but also point out the challenges they bring. We make three key observations. First, although assistance can greatly

ISF is a visual formalism for creating custom notations for high-level software design. In this paper we describe the formal semantics of ISF in Datalog. The semantics provides useful insight on how deductive database technology can be used to generate tools to support our custom notations. 1

with the tight resource constraints typical of this field. Moreover, the traditional Linda matching semantics based on value equality are not appropriate for context-aware computing, where queries are often formulated over value ranges, and where there is a prominent need to deal with imprecise information

Abstract. Current user interface modeling languages usually focus on modeling a single user interface and have a fixed set of user interface components; adding another user interface component requires an extension of the language. In this paper we present CASSIS, a concise language that supports

Abstract—Web portals provide a standardized way of integrating multiple information sources and applications in a single web interface. However, they currently do not provide semantic support for users that need to navigate the often overwhelming amount of content. We demonstrate our open source

processes and by offering information to the outside world. We can use portals in decision making in two ways. One way is by enabling managers to access the data they require by using the portal's interface. Another way, which doesn't exclude the first, is by developing a distinct decision support

in on-line user studies, as well as with an expert evaluation of the whole system. Index Terms—interactive systems; user interfaces; semantic web; decision support systems; environmental factors; I.

for the GUI, as well as for data communications. Therefore, there are powerful motivations for using existing static analysis tools in conjunction with WWW technology to implement browsers for distributed software projects.
