The workplace environment is intrinsically dynamic, yet architecturally it is treated as something that is fixed. Functional layouts specific to the thinking of the time (zeitgeist) are built into the structure leaving little opportunity for adaptation. Frank Lloyd Wright’s Johnson Wax building is one such example; built to function in the Taylorist paradigm with little scope for alteration. The contemporary workplace often lends itself to the adaptive reuse of a range of building typologies or the construction of new structures with Green Star ratings. At the same time, a significant amount of office buildings, constructed prior to the green building movement of the 1990’s, are still in use, despite the typically hermetic and unhealthy spaces they contain. The possibility of adapting an office building from pre-1990 building stock is investigated. Previous workplace layouts inhibited conversation (since interaction in the workplace was frowned upon), but today workplaces are designed with social interaction as its core. The largely unused potential of this aspect within corporate culture and the influence it might have on spatial organisations is investigated. Interior architecture, as mediator between office buildings’ accommodation and their dynamic programs, forms the premise of the study. The hypothesis that an interior architectural intervention can make a positive translation from an unhealthy to a healthy building is tested by designing for the interplay between the character of a space and its design elements. The design process is guided by the Open Building methodology of fixed, semi-fixed and loose-fit. The intervention translates this methodology into a responsive and context conscious proposal with an emphasis on the users and their sense of place. Finally, traditional architectural elements are reinterpreted in terms of their ability to enable or disable interaction between users according to the theory of social friction. Three types of interaction are considered: official meetings, casual meetings and chance encounters. Human interaction, central to the creation of a workplace as opposed to a work space, is a constant theme throughout the study. / Dissertation MInt(Prof)--University of Pretoria, 2013 / Architecture / MInt(Prof) / Unrestricted

Using an automated service to access information via the telephone has become an important productivity enhancer in the developed world. However, such automated services are generally quite inaccessible to users who have had little technological exposure. There has been a widespread belief that speech-recognition technology can be used to bridge this gap, but little objective evidence for this belief has been produced. To address this situation, two interfaces, touchtone and speech-based, were designed and implemented as input modalities to a system that provides technologically unsophisticated users with access to an informational/transactional service. These interfaces were optimised and compared using transaction completion rates, time taken to complete tasks, error rates and user satisfaction. The speech-based interface was found to outperform the touchtone interface in terms of completion rate, error rate and user satisfaction. The data obtained on time taken to complete tasks could not be compared as the DTMF interface data were highly influenced by people who are not technologically unsophisticated. These results serve as a confirmation that speech-based interfaces are more effective and more satisfying and can therefore enhance information dissemination to people who are not well exposed to the technology. / Dissertation (MSc)--University of Pretoria, 2006. / Computer Science / unrestricted

This thesis investigates the possibility of detecting weak vital signs, such as heartbeat and respiration rate, through the implementation of quadrature demodulation and frequency spectrum algorithms on a high performance digital signal processor. This thesis has been part of an ongoing research project at Linkoping University, with the aim to develop a sensor platform for wireless measurements of these vital signs. This sensor platform has been expected to consist of two major physical devices, a RF-radar front-end including a quadrature multi-port and a processing back-end which holds the implementation of the algorithms to detect the vital signs. The back-end consists of a data acquisition- and a processing-part which together forms the digital signal processor. The results show that the implemented algorithms works in terms of being able to find artificial vital signs from quadrature signals. This result also confirms that the hardware solution proposed during this thesis, has been considered as viable for the aim of the project.

This study looks at creating a mobile application prototype of Faculty of Management of University of Economics Prague. The theoretical section discusses the digital product design process, the particularities of the mobile user interface and general cognitive theory. In the practical section, personas and product functional requirements are modelled using user research. The key application structure is designed on the basis of these requirements and cases of use. Finally, an interactive prototype is created and the most important parts of the application are refined using visual design.

In today's world there are many different substitutes for most products and services, increasing the demands on decision-making among substitutes. In order to make a decision, it may be very helpful to use multi-criterial methods for evaluating of the options, which are available to the general public through special programs. Thank to these programs, the general public does not have to be informed in detail about multi-criterial methods and can use the convenience of multi-criteria analysis. The aim of this thesis is to describe and compare the publicly available noncommercial czech software that allows the simplification of choice when choosing from several options according to specified criteria. The thesis work is focused on discrete models of evaluation that are simpler and more suitable for pre-defined alternatives. Non-commercial programs, many of which were created at universities, are evaluated in this thesis. Furthermore, some very well-known evaluation methods, which appear in some programs, are presented.

This report presents a development of an analytic tool for advisors, developed with a usercentred design process. The tool is developed to help advisers enhance profitability in a company in a simple and flexible way, and to convey the knowledge to their customers. The report focuses on usability and visual representations to present data from an analysis of the operating branches as well as key performance indicators. The work has a usercentered design process divided into four steps and performed by a pre-study and two iterations. The prestudy was the basis of the project, which included a literature study, interviews compiled to two persons and an effect map. The first iteration began with exploring different visual representations for an analysis of the operating branches and key performance indicators. The visual representations were user-tested through a questionnaire. The second iteration developed the tool by designing and implementing a prototype in the program React in order to be user-tested. The test focused on the visual representations and was performed through task-based questions, Likert-questions about the visual representation and the standardized questionnaire System Usability Scale. The report concluded that users thought that bar graphs, tables and texts are the easiest tools to use. The visual representations can therefore be used to visualize economic values. However, a bullet graph was more likely to be chosen in order to visualize key performance indicators. Bullet graphs contain a lot of information, which makes the diagram complex for the user to understand. A simple and fast tool should therefore be limited and use the details-on-demand of the information visualization mantra to enable the user to obtain more information when needed. The tool is not fully developed and more iterations are needed to complete a final product. / Denna rapport presenterar utvecklingen av ett analysverktyg för ekonomiska rådgivare med inriktning på lantbruk, utvecklat genom en användarcentrerad designprocess. Verktyget är utvecklat för att hjälpa rådgivare att förbättra lönsamhet i ett företag på ett en-kelt och smidigt sätt, samt förmedla kunskapen till sina kunder. Examensarbetet fokuserar på användbarhet och visuella representationer för att presentera data från en driftsgrensanalys samt nyckeltal. Arbetet använder en användarcentrerad designprocess uppdelat i en förstudie och två iterationer. Förstudien låg till grund för projektet och innehöll en litteraturstudie, intervjuer sammanställt till två personer och en effektkarta. Första iterationen utforskade olika visuella representationer för en driftsgrensanalys och nyckeltal. De visuella representationerna användartestades genom en enkätundersökning. Den andra iterationen utvecklade verktyget genom att designa och implementera en prototyp med React för att användartestas. Användartestet fokuserade på de visuella representationerna av resultatet och utfördes genom uppgiftsbaserade frågor, Likert-frågor om den visuella representationen och en standardiserade enkäten för att undersöka användbarheten (System Usability Scale). Resultatet visade att användare tycker att stapeldiagram, tabeller och texter är de enklaste verktygen att använda. De visuella representationerna går därför att använda för att visualisera ekonomiska värden. Visualiseringen för nyckeltal gjordes med ett nysansdiagram vilket fungerade bra med förklaring. Visualiseingen innehöll mycket information vilket gjorde den komplext vid första anblick för användaren att förstå. Ett enkelt och snabbt verktyg bör därför begränsas och använda sig av informationsvisualiseringsmantrats detaljer vid efterfrågan (details-on-demand) för att ge användaren möjlighet att få mer information vid behov. Verktyget är inte färdigutvecklat och fler iterationer behövs för att färdigställa en slutlig produkt. / <p>Examensarbetet är utfört vid Institutionen för teknik och naturvetenskap (ITN) vid Tekniska fakulteten, Linköpings universitet</p>

This thesis explains the process of two researchers conducting a formal analysis of the graphical user interfaces (GUIs), specifically the heads-up displays (HUDs), of the main entries of the two game series The Elder Scrolls (1994 - 2011) and Deus Ex (2000 - 2011). The goal: to see how the evolution of their HUDs over time compare and to analyse them. After playing the games and taking notes about their HUDs, the researchers find that there is a common trend between the two series. The HUDs become more simplified over time, with some non-critical elements of the HUD being removed. They also become more precise at instructing and informing players about how to play the games. While similar additions and changes are made, the timing is different and the researchers conclude that further research is necessary in order to decide if the observed pattern of HUD evolution is unique to the two series or can hold up as a framework for a larger selection of games. As is, this thesis presents the patterns and trends within the heads-up display design of the observed games as well as a library of the observed games’ GUI elements, that future GUI designers and researchers can use to be made aware of past design decisions and revisions that has been common throughout several other games within the genre. / Denna kandidatuppsats går igenom undersökningen utav heads-up displays (Förkortas till HUD, uttalas “hadd”) som en del av de grafiska användargränssnitten tillhörande spelserierna The Elder Scrolls (1994-2011) och Deus Ex (2000-2011). Målet var att se till hur dessa utvecklades med tidens gång. Efter att data hade samlats in från spelen kom författarna fram till att det fanns en gemensam trend för hur HUDar i de två spelserierna utvecklades. Dessa HUDar hade blivit simplifierade med tiden, där icke-kritiska element försvann. De hade också blivit bättre på att instruera och informera spelare i hur de spelar spelen. Samtidigt som liknande tillägg och förändringar skedde för båda spelserierna så skiljde sig tidpunkten för när detta skedde. Författarna kom till slutsatsen att mer forskning är nödvändigt för att det ska kunna fastslås huruvida det observerade mönstret är unikt till de observerade spelserierna eller kan appliceras på andra spelserier också. Denna kandidatuppsats presenterar de mönster, designtrender, samt ett bibliotek av de komponenter, som funnits i datorspelens HUDar och kan användas av gränssnittsdesigners och forskare för att få insikt om tidigare designval och förändringar som har blivit vanligt förekommande genom flera andra spel av samma genre.

Zustandsveränderungen von Maschinensystemen äußern sich in der Erhöhung, Verschiebung oder Häufung von Schwingungsamplituden. Die dynamische Datenerfassung war schon immer das Herzstück jeder Schwingungsmessung. Es reicht aber nicht aus, nur Daten zu erfassen, sondern es muss auch möglich sein, die Rohdaten zu analysieren, zu verarbeiten und in aussagekräftige Inhalte zu interpretieren, um Rückschlüsse auf den Qualitäts-, Wartungs- und Schädigungszustand ziehen zu können. Diese Arbeit behandelt die Entwicklung eines App-basierten Messsystems zur messtechnischen Erfassung, Analyse und Visualisierung von Schwingungssignalen, um eine aussagekräftige Zustandsbeschreibung vorzunehmen. Ferner betrachtet sie verschiedene normative Verweise, welche in der Messgeräteentwicklung und Schwingungsdiagnostik relevant sind.
