Imitation of human behavior by computer systems
Kovaľ, Jakub ; Sigmund, Tomáš (advisor) ; Pavlíček, Antonín (referee)
This thesis deals with concept of artificial intelligence, mainly with attempts to imitate behavior of human beings. It uses theoretical findings of experts at this area. It lays out theories of A. Turing, his imitation game, concept of learning machine and implications of Turing Test. It examines critique of imitation game by J. R. Searle and his mindtest chinese room together with term intentionality and understanding, necessary for real conscious manifestations of intelligence. Limits of artificial reason by H. Dreyfus are also mentioned. Thesis analyzes chosen current systems which try to mimic human behavior. I puts into correlation their function and theories of individual philosophers. It doesn't restrict itself on strict evaluation of systems as whole, but also explore their parts and methods they use to solve given tasks. Thesis closes with summary of requirements accomplishment by individual programs according to listed theories, their meaning in context of artificial intelligence and hints a path development in this area is going to take.

User interface in view of cognitive science
Šilar, Pavel ; Sigmund, Tomáš (advisor) ; Bruckner, Tomáš (referee)
User interfaces of operating systems were often developed according to technological and marketing restrictions. Recently, more emphasis is aimed on the user who uses the operating system. User interfaces, which correspond to user's behavior and expectations, are designed. Cognitive science commits itself in the research of a human mind phenomenon. Its base was used to settle aspects of a human thinking which are related to a user interface and its functionality. It is mainly area of UI design, text elements and functions. Overall model of the user interface was established following recognized conclusions. This model was used to verify, if existing operating systems correspond to findings about the human mind. Correspondence among operating systems and cognitive science was recognized during the comparison of existing operating systems and the created model. Also some insufficiencies were identified, mainly in the area of stereometric design, using of gestalt principles, support of a user's training and involving learning methods of the artificial intelligence. Design of the user interface can be improved in these four areas to ensure better coherency with the human mind.
