Impact of Subjective Visual Perception on Automatic Evaluation of Dashboard Design
Hynek, Jiří ; Herout, Adam (referee) ; Kuric,, Eduard (referee) ; Hruška, Tomáš (advisor)
Analýza vlastností uživatelských rozhraní založená na použití metrik a kvantitativních pravidel grafického designu se zdá být slibným přístupem pro automatické hodnocení vizuální kvality uživatelských rozhraní. Přestože tento přístup nemůže plně nahradit uživatelské testování, může poskytnout dodatečné informace o možných problémech návrhu uživatelských rozhraní v počátečních fázích vývoje a ušetřit tím čas a výdaje v budoucnu. Příkladem je analýza použitých barev a rozvržení grafických elementů na obrazovce. Návrháři uživatelských rozhraní mohou měřit vlastnosti uživatelských rozhraní za použití známých metrik založených na analýze pixelů bitmapy (např. barevnost) nebo grafických elementů (např. vyvážení, symetrie). Problémem použití metrik nicméně je, že tento přístup zpravidla nezohledňuje subjektivní vnímání uživatelů (např. subjektivní vnímání barev nebo grafických elementů rozmístěných na obrazovce). Dnešní uživatelská rozhraní (jako například rozhraní dashboard) jsou komplexní. Skládají se z několika barevných vrstev, obsahují překrývající se grafické elementy, což může zvyšovat nejednoznačnost vnímání tohoto rozhraní uživateli. Může být proto komplikované vybrat takové grafické elementy, které odpovídají elementům rozpoznaným uživateli v souvislosti s principy shlukování vnímaných tvarů (jak je popsáno Gestalt psychologií). Vývoj objektivních metrik a kvantitativních pravidel grafického designu obvykle vyžaduje dostatečně velkou trénovací množinu vzorků uživatelských rozhraní anotovaných dostatečným počtem uživatelů. Tato práce se zaobírá automatickým ověřováním vzhledu uživatelských rozhraní dashboard. Práce kombinuje obecné znalosti týkající rozhraní dashboard s poznatky z oblasti vizualizace dat, vizuálního vnímání a ověřování kvality uživatelských rozhraní a následně zkoumá myšlenku automatického hodnocení vzhledu rozhraní dashboard s využitím metrik. Práce analyzuje vybrané metriky založené na analýze pixelů bitmapy a grafických elementů. Konkrétně zkoumá, jakým způsobem uživatelé rozpoznávají grafické elementy v rozhraních dashboard a výsledky aplikuje pro hodnocení schopnosti metrik (analyzujících grafické elementy rozhraní) objektivně rozpoznávat dobře navržené vzorky rozhraní dashboard. Dále představuje framework pro návrh a vylepšení metrik, který využívá pro vylepšení vybraných metrik. Následně navrhuje metodu pro segmentaci rozhraní dashboard do regionů, které mohou být použity jako vstupy pro tyto metriky. Závěrem práce porovnává vybrané metriky s hodnocením rozhraní uživateli a pokládá otázky vhodné pro budoucí výzkum.

Berková, Petra ; Katunský,, Dušan (referee) ; Tuza,, Karel (referee) ; Vaňková,, Marie (referee) ; Vlček, Milan (advisor)
This thesis deals with the properties of soundproof partition structures in the low-frequency sound at impact sound insulation and security of acoustic comfort inside buildings. The prediction of impact sound is a simulation laboratory measurements of impact sound. The work is based on the occurrence of frequent complaints of inhabitants of residential homes for subjectively poor impact sound insulation of horizontal dividing structures, whose top layer is formed laminate. Although these structures conform in terms of impact sound insulation in accordance with the requirements of CSN 73 0532: 2010, residents complain about the subjective perception of the sounds of lower frequencies. A noise with a distinctive character of sound at low frequencies has been proved by measuring the spectral analysis and evaluation of sound pressure levels caused by the movement of persons roof construction to the floor. On the measurement and evaluation carried out in accordance with the measurement and evaluation of noise in non-working environment can be related requirement under the Regulation No. 272/2011 Coll. "On the protection of health from the adverse effects of noise and vibration." Occupational noise limits for protected buildings interior space do not apply to noise from ordinary use of the apartment. Under current legislation, the problem is in the Czech Republic at present insoluble. Therefore, this work explores ways evaluation of impact sound and delivery is determined conclusions. With the low-frequency impact sound insulation is also related to the latter part of this dissertation, where the computing program ANSYS (version 14.0) is simulated laboratory measurements of impact sound insulation of the real structure. The paper presents the results of simulation, and the sound pressure level in the receiving room to třetinooktávového band 630 Hz. These results are compared with measured values modeled in the laboratory.

A mixture of symbols, authorities and theories that man need´s to absorb nowdays, is source for many confusing manuals, how to deal with our life, make decisions, or which political party to vote. Exactly the same time, these symbols of authority and theories are an essential part of our culture and education, and that they are looking for inspiration, information and explanations. Sometimes I dream that my source of information is nothing more than nature and its observations. In a utopian world without information provided by them I watched the world at my own pace, subsequently walking from one information to another.In the real world from different disciplines, which explore the universe in great detail, vast quantities of information flows, which the ordinary man in his level is not capable scientificly understand. For instance, when I read about Hawking's paradox, I can imagine how it's probably meant, but I don´t understand the calculations, and resources .. Well anyway, I add this information to my concept of understanding space and black holes. I perceive universe through intuition and its fragments-specific expression of the universe- I perceive through reason. The first series is a picture of my view of the universe by means of symbols - codes that people agreed use- to communicate the inexpressible. Universe is still on the eyes, and whenever I start to deal with its sub-parts, I can recognize its wholeness .

The perception of health and illness in the lay public in the Vysočina region
NETOPILÍKOVÁ, Lenka
Introduction: The subjective perception of health and diseases is a factor affecting health condition of every one of us. Many times, in health facilities we meet with laymen who do not know the definitions of health, diseases and often they also do not know which factors damage their health. That can result in trivialization of the problems or overuse of medical services. Objectives of the thesis: The thesis aims to find out how does the lay audience in the Vysočina Region perceive health and disease, what it does for its health and how would it describe health promoting and health threating behavior. Methodology: For fulfilling the objectives the qualitative form of the research using semi-structured interview with twenty informants from lay audience was utilized. The selection of informants was intentional on the basis of preset criteria. It was ten men and women of various age categories. The gathered data were then literally rewritten and analyzed. Results: It turns out that perception of health and disease is highly individual, and many factors play a role in it. Many times, the idea of informants diverge from available literature. The difference in perception is apparent even in determination of the boundary between health and disease. The results shown that people who underwent some mild illness in the past and now they are in good health do not feel healthy. On the other hand, informants suffering from chronic disease do feel healthy. From the perspective of perceived risk factors which could damage health the informants mostly mentioned environment in which the individual grows up. It was also found out that most people do not do the maximum for their health and that they do realize their shortcomings. Conclusion: Knowledge of perceiving health and disease appears as very substantial due to need of education and prevention. In this regard it is mainly beneficial for offices of general practitioners which are in primary care and very often educate and inform their patients in the area of health and healthy lifestyle.

Concealed damage the ceiling to the floor, or the lack of assessment of impact sound?
Berková, Petra ; Berka, Pavel
Based on the complaints of users apartments was found essential, mainly relating to ceilings to the floor, at which the top layer consists of laminated . Although these structures conform in terms of impact sound , residents have repeatedly complained about the poor acoustic comfort especially in the perception of movement across the floor in a higher floor. Spectral analysis of the noise source (the movement of persons roof construction with floor) were found to be the source of significant noise components in the low frequency range (31,5 to 40) Hz , that is outside the area of impact sound insulation rating per local legislation.
