Hybrid systems are characterized by the hybrid evolution of their state: A part of the state changes discretely, the other part changes continuously over time. Typically, modern c...
In this paper, we outline a framework for the development of natural language interfaces to agent systems with a focus on action representation. The architecture comprises a natur...
Multiple-monitor computer configurations significantly increase the distances that users must traverse with the mouse when interacting with existing applications, resulting in inc...
A concept of complex objects, being artifacts that have one real physical part and several virtual parts representing certain aspects of the object, is introduced. These parts are ...
In this paper, we explore how to add pointing input capabilities to very small screen devices. On first sight, touchscreens seem to allow for particular compactness, because they ...
