The theoretical part generally characterizes the discipline of Human Computer Interaction. Furthermore, it characterizes concepts such as user interface, web usability and web accessibility and information architecture. Besides, it introduces the organisation, functions and services of the Central Library of the Faculty of Arts, including departmental libraries. The practical part explores and assesses current condition of the websites of the departmental libraries. The aim of this research is to determine users' satisfaction based on their experience with these library websites. Moreover, the research monitors the users' idea of an ideal website. A further concern is the usability, accessibility, content, design and information architecture of the websites researched. In accordance with the results of the research, a schema of a new human interface for the departmental libraries is designed.

(in English): Chatbots are automatised computer programs which are built to simulate an exchange in communication with a human being. Simultaneously, they provide new user interfaces. In 1994, Jacob Nielsen defined ten heuristic rules that are traditionally used within the design of user interfaces. This thesis's aim is to find out whether these ten rules are applicable in new fields of conversational environments. Secondly, what are the conditions under which the exchange becomes possible. The matter was examined through a qualitative research with the sample of eleven respondents who'd created chatbots within the Czech professional environment. The next step was a grounded analysis of existing established theories. The theoretical part explains the context in which chatbots are being created. It also shows theoretical canons of user interfaces which are the base of data and experience for the researches.

Die industrielle Instandhaltung ist ein erheblicher Kostenfaktor während der Betriebsphase einer verfahrenstechnischen Produktionsanlage. Insbesondere der Mangel an technischen Möglichkeiten zum Informationsaustausch des Instandhaltungspersonals mit der digitalen Anlage während der Arbeiten im Feld erzeugt hohe Kosten. Durch die entstehenden Medienbrüche sinkt die Qualität der Informationen in der Digitalen Anlage erheblich. Mobile Informationssysteme können diese Medienbrüche beseitigen und die Informationsqualität in der Digitalen Anlage entscheidend verbessern. Das Konzept der Distributed Wearable User Interfaces (DWUI) stellt einen integrierten Ansatz zur flexiblen Zusammenstellung gebrauchstauglicher Benutzungsschnittstellen für komplexe Arbeitsabläufe in widrigen Arbeitssituationen bereit. Diese setzen sich aus Interaktionsgeräten zusammen, die in einem kabellosen körpernahen Funknetzwerk miteinander verbunden sind und in ihrer Kombination die Benutzungsschnittstelle zu einem mobilen System bilden. Die Geräte sind ergonomisch und funktional optimal am Körper des Nutzers verteilt, wobei jedes Gerät eigenständig nutzbar und für eine bestimmte Aufgabe oder einen bestimmten Nutzungskontext optimiert ist. Die Ein- und Ausgaberäume der Geräte werden in einem integrierten Interaktionsraum harmonisiert. Im Rahmen dieser Arbeit wird zunächst der Nutzungskontext der mobilen IT-gestützten Instandhaltung verfahrenstechnischer Produktionsanlagen im Hinblick auf Nutzungsszenarien und Anwendungsfälle für mobile Informationssysteme festgelegt. Darauf aufbauend werden Anforderungen an derartige Systeme spezifiziert und Gestaltungsgrundlagen und Empfehlungen speziell für DWUI-basierte mobile Informationssysteme erarbeitet. Anschließend wird eine Reihe spezieller Interaktionsgeräte vorgestellt, die verschiedene Interaktionsprinzipien, Techniken und Modalitäten umsetzen. Um diese Geräte in einem kollaborativen DWUI organisieren zu können, wird ein spezielles Kommunikationsprotokoll entworfen und prototypisch umgesetzt. Eine mobile Anwendung zur Instandhaltungsunterstützung wird vorgestellt, welche das DWUI-Kommunikationsprotokoll unterstützt und mit verschiedenen DWUI-Konfigurationen vollständig bedienbar ist. Diese Anwendung wird integriert in ein komplexes Unternehmensnetzwerk, über das sie Zugriff auf industrietypische computergestützte Planungswerkzeuge erhält. Anhand des resultierenden Gesamtsystems werden die prinzipielle Tauglichkeit und die Vorteile des DWUI-Konzepts demonstriert.

The project that is presented in this report is the result of a master thesis for the Industrial Design Engineering programme at Luleå University of Technology. The project was conducted towards and together with the company Leosol during the fall of 2020.  For the past couple of years, Leosol has invested time and money into online advertisement. Their advertisement generates a greater visit flow onto their website; however, it rarely produces any bookings of their services. Leosol wants to increase the number of bookings done through their website. This master thesis is conducted to contribute towards Leosol’s goal regarding the online bookings. Therefore, the focus of this project has been to strengthen Leosol’s brand by exploring options for a new graphic profile and a visual brand language. These brand tools were be implemented in a new website.  To achieve this, an altered version of IDEO’s Human-Centered Design process was implemented. By working close to the user, in this case, Leosol’s clients, the current issues and solutions was clarified. Throughout the process, the graphic profile and the wireframe was developed separately. In the last phase of the project, the two was combined into the final concept.  The project resulted in a repositioning of Leosol’s brand, creating a new, more professional tone. The graphic profile was summarized through a poster, describing the new logotype, colours, fonts, imagery and a short description of how to apply them.  This new graphic profile was applied onto the new wireframe, creating the final website. The layout of the website was developed so that the user can quickly identify Leosol’s identity and mission. By implementing a website that truly represents Leosol, there is a bigger chance that the number of bookings increase. / Projektet som presenteras i den här rapporten är resultatet av ett examensarbete för Civilingenjörslinjen Teknisk Design vid Luleå Tekniska Universitet. Projektet har drivits mot och i samarbete med energiföretaget Leosol under hösten 2020. Leosol har investerat både pengar och tid i annonsering online. Detta har genererat ett större besöksflöde, dock har det inte lett till en ökning av bokningar av deras tjänster. Leosol vill öka antalet bokningar som sker via deras hemsida. Detta examensarbete har utförts för att bidra till detta mål. Projektet har därför kretsat kring att förstärka Leosols varumärke genom att utforska olika alternativ till en ny grafisk profil och ett nytt visuellt varumärke. Dessa nya varumärkesverktyg kommer sedan att implementeras i en helt ny hemsida.  En variant av IDEO’s Human-Centered Designprocess har använts under projektet för att uppnå detta. Genom att arbeta nära och tillsammans med användaren, i detta fall Leosols kunder, har de nuvarande problemen samt olika lösningar förtydligats och identifierats. Under processen har den grafiska profilen och wireframen för hemsidan skapats separat. I sista fasen i projektet kombinerades dessa till det slutgiltiga konceptet. Projektet har resulterat i en ompositionering av Leosols varumärke genom att skapa en mer professionell ton. Den grafiska profilen har sammanfattats i form av en poster. Denna beskriver den nya logotypen, färger, typsnitt, bildspråk samt en kort instruktion som förklarar hur dessa bör appliceras.  Den nya grafiska profilen applicerades sedan på wireframen, för att skapa den slutgiltiga hemsidan. Hemsidans layout är skapad för att användaren ska snabbt kunna identifiera Leosol’s identitet samt deras tjänster. Genom att implementera en hemsida som verkligen representerar Leosol ökar chanserna för att antalet bokningar på deras hemsida stiger.
