Pittsburgh, Pennsylvanien, Vereinigte Staaten Von Amerika

Task: - Simulation of multimodal human-computer interactionMethods: - Cognitive modeling (ACT-R)- Programming (Lisp, Java) Result: - Cognitive models of modality selection

As student worker at T-Labs I crafted a multimodal system using a big wsll-mounted touchscreen and a speech interface as input modalities. I conducted several user studies with the system which were reported in my master thesis and research papers. Task: - Multimodal system developmentMethods: - Programming (Java, Tcl/Tk)- Dialogue Modeling- Touchscreen Interaction- Automatic Speech RecognitionResult: - wall-mounted touchscreen and speech interface
