Board Game User Interface with a Camera
Cihlářová, Dita ; Hradiš, Michal (referee) ; Zemčík, Pavel (advisor)
Cílem této práce je vytvořit systém, který bude schopen nahradit reálného protihráče ve hře Dostihy a sázky. Hra je snímána kamerou, ze které se obraz přenáší do počítače, kde probíhá zpracování obrazu a identifikace herních objektů. Dále aplikace analyzuje stav hry a rozhodne o svém následujícím tahu. Rozhodovací algoritmus je schopen reagovat na každou herní situaci a tudíž dohrát hru do konce. Aplikaci mohou využít hráči, jež rádi hrají Dostihy a sázky, ale chybí jim protihráč. Aplikace také může najít uplatnění jako demostrace možností počítačového vidění.

Gait detection and step counting using smartphone
Kočendová, Kateřina ; Vítek, Martin (referee) ; Němcová, Andrea (advisor)
The focus of this thesis is the detection of walking and running, followed by a step count. Testing is performed on signals of regular daily human activity that involve sections of running, walking or no activity. Those signals are logged using accelerometer in smartphone. The exact type of physical activity performed is distinguished by an average, variation coefficient and wave transformation methods. Basics statistic methods are used to quantify the number of steps taken during either walking or running. Algorithm for activity detection and algorithm for step counting are optimized and tested by a set of signals.

Mobile App for Notifying about Reaching a Location
Ungrová, Klára ; Szőke, Igor (referee) ; Herout, Adam (advisor)
The aim of this bachelor thesis is to create a simple Android application which will be able to send notifications when entering or exiting a zone of user's interest and will overall ease the process of informing other people. Detection of entering/exiting zone is based on the principles of geofencing. SQLite database is used to save user's zones of interest (and details about them) persistently. When crossing the boundaries of a zone of interest, a user receives a notification - by clicking on it a user has the opportunity to send the message to other person. The message to be sent can be preset for every zone (both for entering and exiting). It is possible to activate/deactivate the monitoring of any zone any time. A user can display zones on the map. There is a possibility to send a trial explanatory notification for user to better understand its functionality. The foreground service which takes care of retrieving up-to-date location is running even if the app is swiped away from running applications. To kill the application, the switch off button in the app needs to be pressed. The main focus of this work is design, implementation and testing of the mobile application. The final version has been published to Google Play store.

Application for Data Presentation and Modification in Mobile Devices
Kučera, Pavel ; Ryšavý, Ondřej (referee) ; Trchalík, Roman (advisor)
This thesis is aimed to study the possibility of usage of mobile devices in the sphere of automation. One automation company needed to have in hand some PDA-based tool for a remote control of the technological process. There is analysis of ability of contemporary portable devices to run a application software. According to the specified requirements there is designed and implemented the client-server system based on the VNC technology. The server is a Linux-based PC server implemented using Xinetd daemon and the Xvnc. The two standard VNC clients were made. A free software available under the GPL license was modified to implement them. One runs on Windows Mobile operating system and the other one is a Java MIDlet.

Recognition of vehicles using signals sensed by smartphone
Nevěčná, Leona ; Vítek, Martin (referee) ; Smíšek, Radovan (advisor)
Thanks to the development in recent years, the placement of miniaturized sensors such as accelerometers, gyroscopes, magnetometers, global positioning system receivers (GPS), microphones or others to commercially sold smartphones is increasing. Use of these sensors (which are to be found in the smartphone) for human activity recognition with health care improvement in mind is a discussed theme. Advantages of the use of smartphone for human movement monitoring lies in the fact that it is a device that the person measured carries with them and there are no additional costs. The disadvantages are a limited storage and battery. Therefore, only accelerometer, gyroscope, magnetometer, and microphone were chosen because their combination achieves best results. GPS sensor was excluded for its lack of reliability in sampling and for being energy demanding. Features were computed from the measured data and used for learning of the classification model. The highest accuracy was achieved with the use of a machine learning method called Random Forest. The main goal of this work was to create an algorithm for transportation mode recognition using signals sensed by a smartphone. The created algorithm succeeds in classification of walk, car, bus, tram, train, and bike in 97.4 % with 20 % holdout validation. When tested on a new set of data from the tenth volunteer, the resulting accuracy counted as average form classification recall for each transportation mode reached 90.49 %.

Innovative User Interface for Smartphone
Utěkal, Jan ; Herout, Adam (referee) ; Beran, Vítězslav (advisor)
This bachelor's thesis presents innovative user interface for Symbian S60 5th edition operating system. It describes the process of development of an innovative control of a cell phone. It outlines the tasks and designs the solution from partial thoughts to the final form of a control component. The purpose of the component is simplifying the work with the device and improving its efficiency. The text also covers the implementation details for Symbian C++ programming language and results of experiments on a group of users. The whole topic is enclosed by discussion about the future development of the project and its possible usage.
