GUI testing is expensive to perform manually. Software systems involving a heterogeneous set of components exclude the applicability of specific GUI testing techniques. Visual GUI Testing (VGT) is a test automation technique that combines image recognition with scripts. It applies to almost any GUI driven application. VGT is proven to be cost-effective in comparison with manual testing. Still, it is expensive to maintain. This study investigates if test script design by following specific guidelines positively affects maintenance costs. A case study was conducted to identify best practices for VGT w.r.t. maintenance time. Four VGT versions were developed for each manual test case. These consisted of two design versions, with/without guidelines, for the two VGT-tools EyeAutomate and Sikuli. Data was collected using time measurements, observations, and interviews. Results highlighted differences in initial development time and maintenance time between the two design versions. In total, 44 observations were collected. 17 were related to the design versions, 17 to the VGT-tools, and 10 to VGT in general, initial development, and the system under test. The interviews collected the perceptions of VGT in general, maintenance of the different VGT versions, and guidelines. In conclusion, the combination of the guidelines did not have a positive effect on maintenance in terms of costs and experience. However, some of the individual guidelines did. A rationale why the guidelines did not give the desired result was identified. Future research is necessary to investigate other combinations of guidelines, such as those identified as beneficial.

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.

A Stewart Platform robot was designed, constructed, and programmed for use in Cal Poly’s ME 423 Robotics: Fundamentals and Applications laboratory section. A Stewart Platform is a parallel manipulator robot with six prismatic joints that has six degrees of freedom, able to be defined in both position and orientation. Its purpose is to supplement parallel robot material covered in lecture. Learning objectives include applying and verifying the Stewart Platform inverse kinematics and investigating the Stewart Platform’s operation, range of motion, and limitations. The Stewart Platform geometry and inverse kinematics were modeled and animated using MATLAB. The platform was then built using linear actuators, magnetic spherical bearings, and acrylic plates. Control of the Stewart Platform is achieved using an Arduino Due and a custom HexaMoto shield. Users interact with the system using a GUI created with MATLAB’s App Designer.

This master's thesis deals with the design and implementation of universal user interface for detection devices used in Laser-induced breakdown spectroscopy. The design and implementation are based on analysis of current state of instrumentation used in laser spectroscopy. The user interface should be able to work with high repetition frequency of measurement. Acquired spectra should be visualised to user and it is also necessary to save this data on hard drive. The resulting application must be universal. It means the application must support various types and vendors of detection devices.

The growing trend in the share of mobile application use results in higher user expectations for applications. Much more emphasis is placed on both the appearance and ease of use of the applications themselves. This work examines this issue, analyses the market and then uses its findings. From these findings, a proposal for a new application is created, which will be used to promote the newly established company. The work also includes economic and non-economic aspects associated with the development of the application.

The demands we put on the mobile applications we use continues to grow. They should be useful, elegantly designed, secure and effective. If an app does not meet those demands, it is likely that the user will replace it with another one. This thesis work was performed at Visiarc, which is a small company that is specialized at development of mobile- and web applications. They are looking for new ways of improving the performance of their apps. This study investigates whether a performance enhancement can be achieved through migrating the reactive programming components, which are being used to update the graphical user interface of their apps, from JavaScript where they currently are residing in Visiarc's system, to C++. The study explains how the new C++ system for managing reactive programming components was constructed. Two performance tests were created to compare the performance of the C++ system to the existing JavaScript system. The test results showed that further improvements to the native system are required in order to surpass the performance of the JavaScript system. What these improvements are and how to achieve them is briefly discussed.
