Positional system of PC interface controled by electrooculogam
Lutz, Jan ; Kolářová, Jana (referee) ; Janoušek, Oto (advisor)
This project treats of the eye physiology and deals with two specific signals of the human eye. These signals are electromyogram and electrooculogram. Reader is briefed by eye’s muscles, ways of measurement EOG signal with Biopac system and possibilities of using this signal as a simple computer interface. Objective of this project is to create a measurement protocol for EOG signal and find out the resolution of the potencial interface. Very important part of this project is filter designed in Matlab, including simple graphics interface. Besides the text, there are several behaviours of the EOG signal, so one can see that the filter is functional. These signals were measured on my own eye and ten signals come from students. On the behaviours is demonstrated solution of my project. Data from each signal are processed in the last chapter.

Myoelectric prosthetic device of human arm
Lutz, Jan ; Kozumplík, Jiří (referee) ; Kuna, Zdeněk (advisor)
This project treats of using electromyograph as a control standard for prosthetic replacement of human arm. The work is mainly focused on surface signals. Reader is briefed by creation and transmission of the signal. The work takes account of the transmission of the signal for surface electrodes and the differences between the ideal and the real connection. Another point of the thesis is the design of basic system model for simulation of the robotic arm movement, which depends on the measured signal. In the practical part there is the realization of the artificial limb movement. It starts with the roboric arm construction and continues with the communication between computer and the robotic arm. First part of practical testing ends with creating of an user interface, which is capable of control all robotic arm movements. The interface is combined with a computer model in Matlab robotic toolbox. The model is able to move in sync with the real robot. The final part is devoted to practical measurement with Biopac instruments. The obtained signal is modified to be used as controller for the robotic arm. Author's aim is to adjust this movement to be most similar to real movement.
