Human-computer interfaces represent the borderline between the computer and the user. People naturally communicate with other people and their environment by means of different modalities, e.g., speech, gestures, touch, and mimic. Therefore, the development of advanced human-computer interfaces, which are more natural, efficient and intuitive is worthwhile ( Bolt 1984). In our department a research group is concerned with the development and evaluation of multimodal human-computer interfaces in technical applications. Where nowadays the most popular input modalities relies on keyboard and mouse, future interfaces will benefit from natural communication modes.According to develop advanced multimodal human-computer interfaces, research is focussed on the following topics:
analysis of natural communication procedure
selection of communication modality and its context-dependent use
suitable combination of input as well as output modalities

Multimodal human-computer communication might be appropriate for operating a wide range of applications, e.g., multimodal information browsing. Regarding technical applications, such as machine tools, it will be advantageous if the user can operate the machine in a hands-free and eyes-free manner instead of using a keyboard-and monitor-based input system. A multimodal input device can be a useful add-on or even a substitute for common input devices. It creates new functionality and comfort for controlling technical systems.

System Architecture

The system architecture for multimodal human-machine communication is depicted in figure 1.
