Abstract. In this contribution, we want to summarize recent development steps of the embedded cognitive user interface UCUI, which enables a user-adaptive scenario in human-machine or even human-robot interactions by considering sophisticated cognitive and semantic modelling. The interface prototype is developed by different German institutes and companies with their steering teams at Fraunhofer IKTS and Brandenburg University of Technology. The interface prototype is able to communicate with users via speech and gesture recognition, speech synthesis and a touch display. The device includes an autarkic semantic processing and beyond a cognitive behavior control, which supports an intuitive interaction to control different kinds of electronic devices, e. g. in a smart home environment or in interactive respectively collaborative robotics. Contrary to available speech assistance systems such as Amazon Echo or Google Home, the introduced cognitive user interface UCUI ensures the user privacy by processing all necessary information without any network access of the interface device.
Research backgroundThe joint research project Universal Cognitive User Interface (UCUI) 2015-2018 is developing methods, data and a prototype [1] to easily manage connected home appliances (as example scenario) by corresponding intuitive actions of the users. In the framework of our contribution, some preliminary results from the UCUI project shall demonstrate the potential for a novel class of interfaces for the humanmachine or human-robot interaction.With UCUI, the user can control the system via speech, gestures or even a virtual keyboard. The system is designed to operate autonomously, neither using an extensive database nor a network connection. Recent speech dialog systems and cognitive user interfaces allow a verbal, natural human-machine-interaction and achieve an excellent performance. However, the leading commercial solutions heavily rely on transmitting sensitive user information such as personal data or voice recordings through public networks and on processing, storing and analyzing the data on servers of external service providers.The UCUI demonstrator is realizing a cognitive user interface for intuitive interaction with arbitrary electronic devices and ensures privacy by design. The system collects user-specific data which are processed by a cognitive behavior control to allow an adaptation to the users' communication style and to improve the strategy in problem solving. The underlying paradigm requests a systems' adaptation to the user and not vice versa, assuming the fact, that such systems are mainly used by human beings who are less trained in the use of complex technical devices. In addition, user-specific data are not delivered to other users to avoid possible conclusions from these data. In order to achieve an appropriate system behavior, a variety of possible human-machine interactions needs to be integrated into the UCUI system, since alternative input phrases may have an identical meaning in speech control.
