Klávesnice pomocí pohledu
Sznapka, Jakub ; Herout, Adam (oponent) ; Hradiš, Michal (vedoucí práce)
Cílem bakalářská práce je vytvoření nástroje pro psaní pohledem. Zabývá se problematikou snímání pohledu a jeho vyhodnocováním. Obsahuje popis metody Swype, která se používá při psaní na dotykových displejích. Následuje rozbor různých způsobů, pomocí kterých je možné modelovat jazyk, který nástroj používá. Hlavní část práce se věnuje samotnému návrhu nástroje, jenž umožňuje psaní pohledem a jeho implementaci za pomoci toolkitu Kaldi.

Eye Tracking During Interaction with a Screen
Pavelková, Alena ; Kajan, Rudolf (oponent) ; Herout, Adam (vedoucí práce)
This work presents system for real-time tracking of computer screen and estimating location of user's gaze on this screen with the use of eye-tracking data from a head-mounted eye-tracker and Uniform Marker Fields. The designed system localizes the computer screen in the frames from eye-tracker's front camera using a fragment of Uniform Marker Field displayed on the screen. The marker is hidden after its successful detection and natural feature points from the camera frame lying on the computer screen or, optionally, from the whole frame, are used for tracking the screen. If the natural features tracking fails, marker is displayed again and the tracking is re-initialized. In order to make the marker as unobtrusive as possible, gaze information is used to display the marker as far from the area of user's visual attention as possible. To evaluate the performance and accuracy of the implemented system and the influence of marker appearing on the screen on user's ability to perform his work, several experiments and user testing were conducted.

Eye Tracking in User Interfaces
Jurzykowski, Michal ; Beran, Vítězslav (oponent) ; Zemčík, Pavel (vedoucí práce)
This MSc Thesis was performed during a study stay at the University of Eastern Finland, Joensuu, Finland. This thesis presents the utilization of Eye-Tracking technology in Human-Computer Interaction (HCI). The proposed and implemented system is able to map co-ordinates in the plane of a scene camera, which correspond with co-ordinates of the point of gaze, into co-ordinates in the plane of a display device. In addition, the system compensates user's motions and thus removes one of main problems of use of Eye-Tracking in HCI. This is achieved by determination of a transformation between the projective space of scene and the projective space of display. Method is based on detection and description of interesting points by using SURF, matching of corresponding points and calculating of homography. The system has been tested by using testing points, which are spread over the display area.
