Abstract: [cze] [eng]
Táto bakalárska práca sa zaoberá porovnávaním dát z chytrých telefónov, náramkov a špecializovaných zariadení. V práci je zahrnutý popis možností záznamu pomocou rôznych zariadení ako je chytrý telefón, náramok Axivity AX3 a Fitbit Alta HR. Pomocou týchto zariadení boli nasnímané signály s rôznymi umiestneniami a vzorkovacími frekvenciami. Takto nasnímané signály sa implementovali na tri vytvorené algoritmy pre klasifikáciu aktivít. Pre každý signál sa vypočítala presnos[ detekcie a na základe týchto presností sa porovnali zariadenia, umiestnenia zariadení a vzorkovacie frekvencie. Stanovila sa ideálna kombinácia vzorkovacej frekvencie, umiestnenia a typu snímacieho zariadenia. The focus of this thesis is the comparissement of data from smart phones, fitness bracelets and specialized devices. Thesis includes description of features when using special devices such as smart phone, Axivity AX3 bracelet and Fitbit Alta HR for data recording. Signals were recorded using those devices with different anatomical locations and sampling frequencies. Those data recorded were implemented for three algorithms created for activity classification. Detection accuracy was calculated for each signal recorded. Devices, sampling frequencies and anatomical locations were compared based on the accuracy. Ultimate combination of sampling frequency, anatomical location and suitable device was defined.
