A common way of organizing Windows, Icons, Menus, and Pointers (WIMP) interfaces is to group tools into tool containers, providing one visual representation. Common tool containers include toolbars and menus, as well as more complex tool containers, like Microsoft Offices Ribbon, Toolglasses, and marking menus. The location of tool containers has been studied extensively in the past using Fittss Law, which governs selection time; however, selection time is only one aspect of user performance. In this thesis, I show that tool container location affects other aspects of user performance, specifically attention and awareness. The problem investigated in this thesis is that designers lack an understanding of the effects of tool container location on two important user performance factors: attention and group awareness. My solution is to provide an initial understanding of the effects of tool container location on these factors. In solving this problem, I developed a taxonomy of tool container location, and carried out two research studies. The two research studies investigated tool container location in two contexts: single-user performance with desktop interfaces, and group performance in tabletop interfaces. Through the two studies, I was able to show that tool container location does affect attention and group awareness, and to provide new recommendations for interface designers.

In 2002 the Legislative Tuan promulgated the ¡§Charges Law.¡¨ Undoubtedly this has empowered county and city governments to levy charges/fees. Kaohsiung City Government has thus commissioned us to reexamine the reasonableness of the charges system of Kaohsiung city and study how to enhance the levy of charges, through investigating user charges/user fees, Activity Based Costing, and the charges system of counties and cities. This would increase the revenues of Kaohsiung city and comply with the Charges Law requiring local governments to periodically examine and adjust the regulations on charges. The study has found: (1) The fees charged by Kaohsiung City government agencies for city service can be increased. (2) Fewer than 30% of agencies of Kaohsiung City government as well as other county and city governments charge fees that are permitted by local ordinances and regulations. (3) Kaohsiung City has less revenues derived from levying charges than does Taipei City, primarily because the latter has more high rate, more people using public services and facilities and charges new fees. (4) As indicated by questionnaire survey, government agencies for citizen service of Kaohsiung City are not eager to adjust charges or levy new fees in the future. This study suggests Kaohsiung City to adjust charges and levy new fees in consideration of the distinctive conditions of city, by abiding by the ¡§equal, fair¡¨ principle, and by referring to other county and city governments in this regard.

This research in Langford Building 'A', Texas A&M University, is an attempt to determine the user satisfaction of the new, low consumption toilet fixtures and lavatory valves. 253 surveys were given to the subjects, during the four phases of upgrading the restroom fixtures, to find and compare user satisfaction in each phase. The four phases were: 1. The as-is condition of the flush valves and the lavatory valve. 2. Low consumption manual flush valve and low consumption manual lavatory valve. 3. Old style low consumption automatic flush valve and low consumption automatic lavatory valve. 4. Low consumption manual flush valve and low consumption automatic lavatory valve. The survey analysis for the building showed a positive response from the users for the low consumption valves, but not for the automatic valves, as they did not function as they were expected to.

With the changing on network technology and Internet exchanges frequently, the Internet plays an important role in many people's lives, but also affects the learning, the change of the sale. The survey found that internet users are young than12-year-old is a rising trend. Therefore, construction of children's Web site to make children to feel about the vast Internet information in the information filtering case. Then, to provide a satisfactory experience for users of the site will affect the users of the site's views and re-visit frequently. This study aims to explore the impact on user perceived experience and loyalty of children's web-based service quality in order to understand whether website on providing service quality have different views in different a point of view, as the reference of site designer, web-site operators and follow-up study in the future. The results pointed out that in the course of children's website, the dimensions that the web-based service quality and perceived experience affect user¡¦s satisfaction and user¡¦s loyalty can be summarized as follows: (a) user¡¦s perceived experience of web site can directly impact on user¡¦s satisfaction and loyalty; (b) web-based service quality is required by the user satisfaction indirectly affects user¡¦s loyalty and demographic variables in the study of variable conditions sum up the differences. The management of meaning which are obtained by variance analysis will be able to serve as managers in improving the children's web-based service quality.

Introduction: Enterprise recourse planning (ERP) is a system that combines software, hardwareand people to manage information The aim of this study is to investigate ERP systems effect onbusiness performance (advertised vs. realized benefits) and user’s complaints. It also aims toidentify the most important issue a company faces after implementing an ERP system and if thisstops potential benefits from happening. This will be viewed from a user’s perspective. Approach/Methodology: This research includes qualitative and quantitative primary data withsecondary data to answer the research questions posed. It is based on a number of semistructuredinterviews of people well versed in ERP systems presented in case study form.Alongside, it also utilizes a series of questionnaires presented in tabular form. The data wasanalyzed and linked with theory to provide answers and test assumptions. Findings: ERP systems provide their advertised benefits to a large extent. The most importantorganizational issue after implementing an ERP system is resistance to change and this issueaffects the benefits realization of the system. Finally, user’s complaints about ERP systems arevaried and include the speed of the system, support in error situations and general complexity. Conclusions: Even though it provides many benefits in business performance, an ERP system,selection and implementation in a company is a critical step. The whole process is complicated,resource consuming, takes a long time and can encounter problems. Mistakes in theimplementation cost a company more resources to fix after they happen. In this case preventionis better than cure and the best medicine.Implications and Value of research: ERP system implementation and use should bemethodically planned from the beginning to get maximum benefits realization. This is especiallyimportant in effectively managing change in an organization. In this issue, top level managersshould be aware and committed to. Suggestion for future studies: A possible research that could correlate user complaintcategories already established with age group of respondents under a global perspective.

Owing to a recent online trend of web 2.0, societies have emerged not only culturally but also technologically/virtually. This coupled with semantic web and Web Services have provided end-users with more opportunities to contribute to the web and consequentially have also multiplied their digital needs. One such requirement of a modern-day end-user is to combine the data, view and/or process presented across the web to suit his/her ephemeral needs by developing a novel application known as a service mashup. The end user development of mashup poses significant challenges to the end users. First challenge addressed in this thesis is the scope vs complexity challenge which refers to the impossibility of fully eliminating the technical barrier between a tool and the end user due to the corresponding complexity creeping in while developing new features in tool and extending its scope to provide added functionality. The second challenge arises from the utility=value/effort equation which implies that effort required in developing a mashup decreases the value and hence neutralizes the utility. Given these challenges and the related issues, I made three contributions. The central theme of my proposed approach - for managing these inherent challenges - is that the end user must be integrated into the process of a service composition application. My approach - A Goal-Oriented Mashup Development (GO-MaDe) framework defines, organizes and addresses the problems faced by end-users while composing their applications by proposing a new style of development in the mashup area in a bid to render irrelevant the underlying inherent tensions of the paradigm. My first contribution in this regard is a classification model that takes into account end user centered usability criteria for calibrating mashup tools efforts. Secondly, this research is the pioneer study about the integration of an agile-style analysis-cum-design phase into the mashup development process. Hence, it presents a redefined process of service-based applications development by introducing a spiral process model that introduces a phased, incremental concept of mashup development lifecycle. Based on the spiral model, I have presented a method (KAReM) annotated with domain theory for better acquisition and representation of user requirements encompassed by the APIs or Web Services that are composed to develop a mashup by incorporating the dynamics of goal decompositions using goal based templates. It serves to enhance the end-user experience by facilitating them to explore the problem space and helping them derive the visual representations of their requirements which can then be translated into service compositions. To evaluate my contributions qualitatively and quantitatively I conducted literature reviews, and validated my framework by scenarios and a controlled experiment.

3D user interfaces are common today when for example doing industrial design, architecture and 3dmodelling but they are not commonly used in regular interfaces. The hardware requirements for suchinterfaces are not difficult to reach with today’s computers, laptops and mobile devices with only in-tegrated graphics cards.The report found that users of 3D interfaces found them more fun to use and gives a better overviewwhen viewing dense information. Problems exists when using small screens and reading text. Futureimprovements to software tools and APIs as well as improvements in hardware, and new technologiessuch as virtual- and augmented reality will make 3D interfaces easier to develop, use and run. / 3D-gränssnitt är vanliga idag när man till exempel arbetar med industridesign och arkitektritningarmen de används vanligtvis inte i vanliga program. Hårdvarurestriktioner har varit en stor faktor var-för de inte har haft dessa, men dagens datorer och mobila enheter som har integrerade grafikkort somklarar av att köra de flesta 3D-gränssnitt.Rapporten fann att användare av 3D-gränssnitt tyckte de var roligare att använda och ger en bättreöverblick när informationsdensiteten är hög. Problem uppstår när man använder små skärmar ochbehöver läsa text.
