The SATIN project has the aim to enable end users to create their own mobile applications without prior programming experience, and in this way assist non programmers in the transition to the digital society. In this thesis an environment has been designed anddeveloped, that surrounds the existing SATIN mobile application creation editor, with thepurpose of supporting the developers and facilitate collaboration. Based on the theory of End User Programming, a web-based environment built inDjango, a Python framework, was developed and the existing editor was adapted to functiontogether with this environment. The resulting environment is to be seen as a proof ofconcept for the future progress of the SATIN project.

The aim of this study has been to answer the question whether it is possible to obtain notifications that work with the user, instead of against, which can be experienced as stressful and bothersome. To decrease the stressful notifications an application was created which acted as a notification control. The application used machine learning to predict when the user wanted to receive their notifications. For an artificial intelligence to work there needs to be a pattern recognition. In this case the pattern recognition that was used is called the association rule analysis. The association rule analysis used a tree called fp-growth. After the application was made, a usability test was made before and after the installation of the application. The usability test was testing if the user experienced stress and how the application worked. The study showed that screen time decreased by one hour and the number of times the mobile was opened was also reduced. This survey requires more data as it may be that the user was not affected by the application but only randomly used the mobile phone less. / Denna studie handlade om att försöka minska störande notifikationer som kan upplevas som stressande och irriterande. Det som skapades var en applikation som agerade som en notifikationskontroll. Denna applikation fungerar med hjälp av maskininlärning som ska förutse när användaren ville ta emot sina notifikationer. Den mönsterigenkännande artificiella intelligensen som användes kallas associationsregelanalys. Associationsregelanalysen använde sig av ett träd som kallas fp-growth. Det gjordes ett användartest före installation av applikationen och ett användartest efter för att se hur användaren upplevde stress men även själva applikationen. Studien visade att skärmtiden minskade med en timme och antalet gånger som mobilen öppnades minskades också. Denna undersökning kräver mer data då det kan vara så att användaren inte blev påverkad av applikationen utan endast slumpmässigt använde mobiltelefonen mindre.

This thesis is to help developers in the touch design of casual games. The thesis work was made on the development platform Gideros Mobile and much of the thesis theory and methods will be based on that work. The purpose of the report is to show what one should think about when making a casual game in a touch design perspective, like taking into account that most people are used to one type of input design (like swiping or tapping), that you should design the game with the purpose to reach out to as a large audience as possible (taking into account people with disabilities) and some small notes on what should be avoided so not to deter people from wanting to play the game. It is important to note that this thesis is built for the purpose of mobile casual games, others will probably not find this thesis relevant.

<p>This thesis discusses the possibilities to visualise the presentation layer of a search engine on a mobile device in an alternative way. Previous work in the area has shown that the use of text-based-lists can be problematic when accessed on a device with a limited display. In the scope of the thesis and in order to tackle the current problems when displaying the results a literature review was carried out. The findings of the review formed the basis for a requirement definition on which a mock-up was developed. The mock-up was then evaluated and tested during a usability test where a number of users got to experience the alternative presentation layer that uses a visualisation technique called tree- map. The results from the test show that the mock-up could be seen as a alternative to the current presentation of results. The mock-up also shows that a future implementation could also include the use of categories and sorting of information in order to provide content with a meaning.</p>

The objective of this study has been to answer three questions. The questions are Can you navigate in a different way than with your fingers, Do you lose any functionality in the application when you are not using your fingers and is the solution a reasonable way to navigate. The study consist of two parts, the first is to create a navigation library with different navigation methods and the second part is to evaluate the navigation methods using user tests. The study shows that it is possible to navigate without the use of fingers and address problems and solution to navigate without the use of fingers. The study shows how different navigation methods perform compared to each other and compared to navigating with the use of fingers.

Zur Steigerung der Qualität werden Wartungstechniker bei ihren Rundgängen in Prozessanlagen mit digitalen Assistenzsystemen unterstützt. Dadurch soll diese Arbeit effizienter und weniger fehleranfällig gestaltet werden. Da sich jedoch konventionelle Eingabemetaphern dafür nur bedingt eignen, versucht man Eingabeelemente von dem Anzeigeelement räumlich zu trennen. Um den Einfluss einer solchen Trennung auf die Arbeitsbeanspruchung des Nutzers zu untersuchen, wurde ein Evaluationsexperiment mit zwei Versuchsgruppen durchgeführt. Dabei hat eine Versuchsgruppe festgelegte Wartungsrundgänge mit Hilfe von Assistenzsystemen mit abgesetzten Eingabegeräte durchgeführt und die andere Gruppe mit kombinierten Eingabegeräten. Der Versuch wurde für die drei Interaktionsmetaphern Texteingabe, Navigation in strukturierten Daten und Navigation in Abbildungen mit jeweils angepassten Eingabegeräten durchgeführt. Als Beanspruchungsindikatoren wurden die Pupillengröße, die Zeitdauer und die subjektive Bewertung mit Hilfe des NASA-TLX gemessen. Als Ergebnis zeigt sich, dass kein signifikanter Unterschied zwischen den verschiedenen Ausprägungen der Trennung für alle Interaktionsmetaphern existiert. Daher spricht von Standpunkt der Arbeitsbeanspruchung nichts gegen eine Trennung des Eingabegeräts vom Anzeigegerät. Zur Erhöhung der Qualität der Daten und Präzisierung der Aussage sollte der Versuch mit einigen Änderungen aber erneut durchgeführt werden. / Maintenance technicians are assisted during their operations in process plants with digital assistant systems to increase the quality. This should make the work more efficient and less error prone. Since conventional input metaphors are only limited suitable for this purpose, new input devices are developed which are seperated from the display element. To investigate the influence of such a separation on the work load of the user, an evaluation experiment was conducted with two experimental groups. One group has performed specified maintenance tours with seperated input devices and the other group with combined input devices. The experiment was conducted for the three interaction metaphors text input, navigation in structured data and navigation in images. For each metaphor a suitable input device was used. The workload was measured with the indicators pupil size, time duration and a subjective evaluation with the NASA-TLX. In this experiment no significant difference exists between the various forms of separation for all interaction metaphors. Therefore there is no reason rejecting a separation of the input device from the display device. Nevertheless to improve the quality of the data this investigation should be repetead with some modifications.

Mobile websites and application are used daily by millions of people as a way of communication and entertainment as well as a professional tool. Content rich apps with multiple levels of content hierarchy face challenges due to the limited space of the user interface. It is important that the application has excellent navigation features along with help and search capabilities [1], as navigation of the user interface is one vital aspect for such web and native apps offering to the user a way to explore its content, understand its structure and use the services that they offer. The efficient identification of the navigation pattern and its usability is a key element of the user experience. This paper compares two different mobile navigation patterns: One of the most common navigation patterns known as hamburger menu, and a bottom bar menu. In order to compare the two navigation patterns a usability evaluation, using a demo application that was developed for this purpose, was conducted. Twenty participants took part in the test were their performance along with their subjective feedback was collected. The analysis of the evaluation suggests that bottom bar menu is more efficient than hamburger menu in terms of total completion time. The qualitative feedback of the participants also suggests that their perceive bottom bar menu better than the hamburger menu one. In addition to their contribution for future research, the study results can help professionals choose what mobile navigation pattern to use as well as better know the benefits and drawbacks of their choice. / Mobila webbsidor och applikationer används dagligen av miljontals personer som ett sätt till att kommunicera och till att få samt ge underhållning och det är likaså ett professionellt verktyg. Innehållsrika applikationer med multipla nivåer av innehåll möter hierarkiskt utmaningar på grund utav användargränssnittets begränsade utrymme. Det är viktigt att applikationen har strålande navigationsfunktioner tillsammans med hjälp och sökningskapaciteter [1], då navigation av användargränssnitt är en vital aspekt för webb och integrerade applikationer som erbjuder användaren ett sätt till att utforska dess innehåll, förstå dess struktur och att använda tjänsterna som de erbjuder. Den effektiva identifieringen av navigationsmönstret och dess användbarhet är ett nyckelelement av användarupplevelsen. Denna skrift jämför två olika mobila navigationsmönster: Ett av de mest vanliga navigationsmönstrena känt som hamburgermeny, och en botten-fältmeny. I ordning till att jämföra dessa två  navigationsmönster, utfördes en användbarhetsutvärdering, med hjälp utav en demo-applikation som utvecklades för detta syfte. Tjugo deltagare deltog i testet där deras prestation tillsammans med deras subjektiva feedback samlades. Analysen av utvärderingen säger att botten-fältsmenyn är mer effektiv än hamburgermenyn gällande total slutförandetid. Deltagarnas kvalitativa feedback säger också att de uppfattar botten-fältmenyn som bättre än hamburgermenyn. I tillägg till deras insats för framtida efterforskning, kan studeringsresultaten hjälpa proffs att välja vilket mobilt navigationsmönster dom ska använda och det ger dem även kunskap om fördelarna och nackdelarna av deras val.

This study proposes a new “vocabulary” of gestural commands for mobile devices, based on established bodily practices and daily rituals. The research approach is grounded in a theoretical framework of phenomenology, and entails collaborative improv workshops akin to bodystorming. The combination of these methods is named as “hacking the physical actions” and the significance of this approach is highlighted, especially as a constituting source for the similar researches in this field. The resulting ideas for gestural commands are then synthesized and applied to fundamental tasks of handling mobile phones and explained with a supplementary video.
