"Multimodal Cognitive System for Immersive User Interaction,"

In the recent years many efforts have been made to provide machines with the capability of effectively interact with its users. Here a system is introduced that supplies a virtual guide service to users by means of a mobile device (e.g. Palm, tablet PC, etc.). The architecture takes inspiration from a biological model of the cognitive processes, the Cognitive Cycle, performed by the brain while interacting with other entities. A variety of multimodal interfaces communicates messages to interact adaptively with the user. Results show the effectiveness of the different message modalities in real situation where an user is moving towards a target guided by the system.
