We present evaluation results of a multimodal route navigation system that allows interaction using speech and tactile/visual modes. Various functional aspects of the system were studied, related especially to the IO-modalities and their use as means of communication. We compared the users’ expectations before the evaluation with their actual experience of the system, and found significant diff...

We present a model for adaptive visual language communication based on eye gaze pattern and facial expression analysis. In our approach each basic visual sign can adapt its appearance and level of detail during the communication process. Atomic Communication Units (ACUs) – analogous to graphical output primitives encapsulate the intended denotation, the encoding of the message and a method for ...
