Eye Tracking During Interaction with a Screen
Pavelková, Alena ; Kajan, Rudolf (referee) ; Herout, Adam (advisor)
Tato práce popisuje systém pro sledování obrazovky počítače v reálném čase a určení pozice uživatelova pohledu na tuto obrazovku s využitím dat z eye-trackovacích brýlí a Uniform Marker Fields. Vytvořený systém lokalizuje obrazovku počítače ve snímcích z kamery umístěné na eye-trackeru snímající scénu před uživatelem. V této scéně je detekován marker zobrazený na monitoru počítače. Po jeho úspěšné detekci je marker skryt a ke sledování pozice obrazovky jsou dále využívány významné body detekované ve snímku z kamery ležící na obrazovce, případně z celého snímku. Pokud sledování významných bodů selže, marker je znovu zobrazen a systém je znovu inicializován pomocí detekovaného markeru. Aby byl marker pro uživatele co nejméně nápadný a obtěžující, jsou využity data z eye-trackeru k tomu, aby byl marker zobrazen co nejdále od oblasti uživatelova zájmu. Pro vyhodnocení výkonu a přesnosti vytvořeného systému a rušivosti markeru pro uživatele bylo provedeno několik experimentů a testování s uživateli.

Real-Time Analysis of Audio Signals
Řezáč, Martin ; Schimmel, Jiří (referee) ; Černocký, Jan (advisor)
The goal of this thesis is creation an application, which can perform real-time fundamental frequency tracking of incoming audio samples. According to detected frequencies, the program generates MIDI messages, which are sent to chosen MIDI device. First, the reader is introduced to the issue of fundamental frequency tracking. The following part describes individual methods, especially the one based on spectral analysis of a tone. A description of used technologies is also a included in this part of this thesis. In the following part, the implementation and testing of application are described including opinions of several musicians about this product. At the end, the whole work is concluded and the possible further development is outlined.

Miniature Tracking Device
Šťáva, Radek ; Levek, Vladimír (referee) ; Macháň, Ladislav (advisor)
The main theme of this masters's thesis is to design and make a miniature universal tracking device. This device is primarily for tracking asset, pets or people. For detecting the position data is used GPS technology. Data transmission is carried out via the GSM network. The device is technically solved and realized with respect to miniature size, high battery life and with regard to resistance against water, dust and impact damage. It is selected unique design, suitable for hermeticaly closure of the entire facility. Due to hermetic closure there is any buttons, any connectors and the battery charging is wireless.

Detection and classification of flying objects
Jurečka, Tomáš ; Richter, Miloslav (referee) ; Janáková, Ilona (advisor)
The thesis deals with the detection and classification of flying objects. The work can be divided into three parts. The first part describes the creation of dataset of flying objects. The reverse image search is used to create the dataset. The next part is a research of algorithms for detection, tracking and classification. Subsequently, the individual algorithms are applied and evaluated. In the last part, the design of hardware components is performed.

Sensor Based Motion Tracking and Recognition in Martial Arts Training
Agojo, Stephan ; Sekora, Jiří (referee) ; Harabiš, Vratislav (advisor)
In various martial arts, competitors are interested in quantifying and categorising techniques which are exercised during training. The implementation of embedded systems into training gear, especially a portable wireless body worn system, based on inertial sensors, facilitates the quantification and categorisation of forces and accelerations involved during the training of martial arts. The scope of this paper is to give a brief overview of contemporary technology and devices, describe key methods that are implemented in such devices and as well to provide a project outline. For this reason a literature research was carried out using search engines and databases. The search yielded that devices are capable of tracking activities of daily life; however only one product was found which can track and recognise techniques applied in martial arts training just for the upper body. The realisation of a sensor based tracking system which can track and classify different exercises is possible with present technology. Even so, different challenges such as implementing a sensor fusion and classifier algorithm need to be overcome. Therefore, the project development has to be viewed as an iterative process.

Radar sensors in mechatronics
Pulec, Matěj ; Formánek, Martin (referee) ; Brablc, Martin (advisor)
This work is studying the possibilities of using radar sensors in mechatronics. The theoretical part describes the basic principles of the mm-Wave FMCW radar sensor, along with several examples of their possible applications. The practical part describes three experiments testing the capabilities of this sensor. In these experiments, the the radar was found to be able to accurately and reliably track the position and speed of a moving object. However, problems arose when trying to determine the position of static objects and also when detecting the shape or orientation of both dynamic and static objects. For these purposes, the the tested radar appears to be an unsuitable type of sensor.

Augmented Reality on Smartphones
Minda, Marek ; MA, Patrick Jost, BSc (referee) ; Drahanský, Martin (advisor)
Rozšířená realita je koncept doplňování reálného světa o počítačem generovaný obsah. Díky pokroku v oblasti mobilních zařízení je mnoho možností využití tohoto konceptu na chytrých telefonech. Tato práce zkoumá schopnost současných zařízení s operačním systémem Android zobrazovat fotorealistický obsah a její využití v aplikacích s rozšířenou realitou. Na základě porovnání dostupných frameworků, Wikitude SDK byl zvolen pro implementaci zobrazování budov do rozšířené reality. Pro účely trackingu je použita geolokace.

Recognition of Poses and Gestures
Jiřík, Leoš ; Hradiš, Michal (referee) ; Zemčík, Pavel (advisor)
This thesis inquires the existing methods on the field of image recognition with regards to gesture recognition. Some methods have been chosen for deeper study and these are to be discussed later on. The second part goes in for the concenpt of an algorithm that would be able of robust gesture recognition based on data acquired within the AMI and M4 projects. A new ways to achieve precise information on participants position are suggested along with dynamic data processing approaches toward recognition. As an alternative, recognition using Gaussian Mixture Models and periodicity analysis are brought in. The gesture class in focus are speech supporting gestures. The last part demonstrates the results and discusses future work.
