<p>This paper, the corresponding wireframe documentation including the functional prototype and flowchart document the evaluation and redesign of the beta version of the social networking platform ModernFamilies.net. In order to reveal possible usability flaws for people of different generations, in particular the elderly, a user-centered design approach including an expert review, diary studies and interviews were conducted. The findings reflected the need for consistency and feedback in general. For young children, the concept of the site appeared to behard to grasp. Experienced users found the access and management of relatives cumbersome. Most importantly, the elderly, novice computer users had a hard time getting started with the site on their own because they did not have access to a PC nor internet at their home. The latter and the fact, that some issues might never be solved by traditional usability testing because the user just feels overwhelmed by the vast amount of communication features he is faced with today calls for alternative, more intelligent, ambient interfaces. However, we came to the conclusion that although evaluation of such new technologies with elderly people is not alwayseasy, it is best to be conducted in the participants home or a similar environment.</p> / AGNES

This study explored how the UI of booking sunbeds could be designed to be efficient and effective while being satisfactory to use for novice admin users of the system. Personas were created through a workshop that together with visual heuristics helped drive the design of an initial paper prototype that was evaluated with users. Iterating the design of the paper prototype, a hi-fi prototype was created using Adobe XD. The hi-fi prototype was evaluated using a task-based usability test with seven participants who provided quantitative data of time spent per task and number of clicks required, and qualitative data through a SUS questionnaire along with semi-structured interviews. The prototype was effective and efficient while scoring a high 90 points on the SUS scale. Qualitative data from the participants indicated that the inclusion of transitions and transformation in the UI helped create a playful experience and a system that was perceived to be easy to learn and use. The results and data of evaluating the prototype can help future designers of systems account for transitions and transformations earlier in the design process that could improve the overall usability for novice users in general. / Den här studien utforskade hur ett gränssnitt för ett bokningssystem kunde designas för att vara effektivt och ändamålsenligt samtidigt som användargruppen av administrativa förstagångsanvändare uppfattar systemet som tillfredsställande. En workshop hölls för att skapa personas, vilket tillsammans med visuella heuristiker drev designen av en första pappersprototyp som utvärderades med användare. Med feedback från pappersprototypen skapades en digitalt interaktiv prototyp som utvärderades baserat på kvantitativa data från hur användare klarade av att utföra uppgifter, samt kvalitativa data från semistrukturerade intervjuer och användbarhetsenkäten SUS (System Usability Scale). Prototypen var effektiv och ändamålsenlig och fick 90 poäng enligt SUS-skalan. Den kvalitativa data indikerade att inkluderingen av övergångar och transformeringar i gränssnittet skapade en lekfull upplevelse och gjorde att systemet ansågs vara enkelt att använda. Studiens insamlade data och resultat kan hjälpa framtida designers av system ta hänsyn till övergångar och transformationer tidigt i designprocessen för att öka den generella användbarheten för förstagångsanvändare
