Driver perception in different conditions
Seriš, Jozef ; Belák, Michal (referee) ; Bucsuházy, Kateřina (advisor)
This diploma thesis is focused on the comparison of perception of traffic signs and advertising areas in two different conditions day and night with focus on visual distraction of the driver. The introductory part deals with the analysis of the current state of the elements acting on the driver with an emphasis on mental processes and the senses of drivers affecting traffic safety. The analytical part draws on the videos from driving tests, the whose goals was to monitor the optical reactions of drivers. The resulting data were evaluated with goal to determine the time consuming views of the drivers on individual elements and the compared in different conditions. The last chapter includes the interpretation of the results of the analysis with suggestion of their use to increase traffic safety.

Checking of the Situation Behind the Vehicle
Ryšavá, Kristína ; Bucsuházy, Kateřina (referee) ; Belák, Michal (advisor)
The diploma thesis deals with the issue of control the situation behind the vehicle, in the theoretical part discusses the indirect view from the vehicle, reaction time and possibilities of its measurement and the possibilities of measuring eye movements using eye trackers, The second part of the thesis deals with the description of the measurement method used to obtain the needed data and the analysis of the situation behind the vehicle using rear view mirrors by analyzing the duration of the fixations in the rear view mirrors and the total duration of the view in the rear view mirrors.

Checking of the Situation Behind the Vehicle
Jánošík, David ; Bucsuházy, Kateřina (referee) ; Belák, Michal (advisor)
The diploma thesis deals with the issue of controlling the situation behind the vehicle. The first part of the thesis summarizes the knowledge about drivers, their reaction time and vehicle response, the construction characteristics of vehicles designed to control what is happening behind the vehicle, and the possibilities of measuring the duration of glances in the form of eye tracking. The analytical part contains an analysis of the duration of glances in the rear view mirrors depending on the mirror, the situation and also the driving manoeuvre during the day time. The data was obtained from video recordings of 12 drivers in normal traffic conditions. The duration of the saccades and fixations of glances was evaluated depending on the mirror used, in individual situations and also for selected driving manoeuvres. The conclusion of the analytical part is devoted to the comparison of the duration of glances during selected driving manoeuvres when exposed to stimuli as well as to the comparison of the differences in individual age groups of tested drivers.

Checking of the Situation Behind the Vehicle
Perničková, Tereza ; Bucsuházy, Kateřina (referee) ; Belák, Michal (advisor)
This diploma thesis deals with the control of the situation behind the vehicle. The theoretical part of the thesis summarizes the knowledge about the transport system, the reaction time and the individual phases, including the factors influencing the reaction time and the possible methods of its measurement. Further, there are issues of vision from the vehicle and the rules of safe driving. Explanation is the eyetracking method, the types of these devices, and the methods of visualizing the data obtained from the records. In the analytical part are drawn from data recorded video. There are testing route, testing device, testing vehicle and information about testing drivers. The frequency and length of the individual components of the mirror views were evaluated depending on the selected mirror even without dependence from the data obtained.

Reaction time of Persons Influenced by Alcohol
Ohera, Adam ; Bucsuházy, Kateřina (referee) ; Semela, Marek (advisor)
This thesis is focused on the issue of reaction time of those people who are affected by alcohol. The thesis is divided into two main parts, the first part is focused on the research of the present state and it submits the theoretical background related to the topic of this thesis. The second part describes both the experiments related to the reaction time of the people affected by alcohol and the evaluation of the results of such measurements.

Analysis of the Usual Time of a Driver Observing Specific Objects
Fujačková, Hedvika ; Semela, Marek (referee) ; Bucsuházy, Kateřina (advisor)
This diploma thesis focuses on drivers of motor vehicles and the usual time they spend by specific objects. The theoretical part of the thesis brings an overview of literature on human perception. The eye-tracker is defined here as the instrument used for scanning the movements of the drivers eyes, here are also named its types and its applications in various fields of life. Finally, this part deals with the advertisements placed alongside roads acting as distractive elements. The experimental part builds upon the collected video recordings and offers an analysis of drivers’ observations of outdoor advertisements that attract their attention, mainly billboards.

Analysis of the Reaction Time of a Driver Influenced by Selected Distracting Stimuli
Černohorská, Magda ; Semela, Marek (referee) ; Bucsuházy, Kateřina (advisor)
The diploma thesis deals with the analyses of food consumption influence on driver´s perception reaction time. It describes the food and drink consumption while driving, factors influencing driver´s performance, activities disturbing the driver, foreign researches and studies aimed at distracting stimuli. Practical part of the thesis is focused on driving tests of chosen driver of certain age group in current traffic, interpretation and evaluation of reaction times while driving with no distracting stimuli comparing to driving influenced by food consumption. All the data are concluded in the summary where it´s confirmed that reaction times are significantly prolonged when drivers have a snack while driving a vehicle.

Detection of QRS complex in experimental ECG data
Bucsuházy, Kateřina ; Ronzhina, Marina (referee) ; Vítek, Martin (advisor)
This Bachelor work deals with QRS complex detection. The theoretical part of the presented work is focused on summary of selected methods of QRS complex detection. There is described in detail wavelet transform, which is used for realization of QRS complex detector in Matlab. Specifically is used redundant dyadic discrete wavelet transform and biorthogonal wavelet with odd symmetry bior1.5. The algorithm was evaluated on the standard CSE database. The detector was modified to be able to detect QRS complexes in experimental data.

Delineation of experimental ECG records
Bucsuházy, Kateřina ; Ronzhina, Marina (referee) ; Vítek, Martin (advisor)
This master thesis deals with QRS complex detection and ECG delineation. The theoretical part of this work describes wavelet transform, some of QRS detection approaches and some of ECG delineation approaches. For algorithm realization in Matlab is used redundant dyadic discrete wavelet transform. Algorithm is designed for experimental electrocardiograms of isolated rabbit hearts and it is evaluated through manually determined references.
