PEČENKA P. Chairs /Thesis/, Prague 2011. Charles Univerzity, Faculty of Education, Department of Art Education 89 pages This thesis deals with history of the development of the chair design. As it was evoluting from its lauching until today production. It is focused on the materials, technologies, social and moral infuences which is very important for the resulting design and gradual differences of the funcional chair types. The special attention is paid on the contemporary design and the non-traditional materials influence. It contains my own chair design project and the use of the observations during lessons of art. Keywords: Design, chair, material, curent design, evolution

The purpose for this study is to examine the impact score has on free-form designed games:games without designed goals. The study is aimed towards smaller products and is meant tohelp designers who are looking to implement score into their game with how it could affect theplayer’s relationship to the defined goal, their intrinsic goal, and the purpose of the game. Aprototype game was created that would simulate the free-form design method. The game hadtwo modes: mode A without score and mode B with score added to one of the actions. Resultsfrom observations and semi-structured interviews show that score has a direct impact on theway participants defined both their intrinsic goals and the one set by the game. Participants’perception of the game defined goal shifts as score is added by giving them a clear andunambiguous extrinsic reward.

Students struggle with publishing and uploading their thesis in DiVA - the Swedish digital archive for academic papers (Digitala Vetenskapliga Arkivet). In a mixed methods usability test of the publication form with 7 users, it was shown that the overall usability was low. Three aspects of usability were tested using the following metrics: efficiency by total task time, effectiveness by task completion and satisfaction by PSSUQ and SUS. 22 usability problems were found and prioritised using a 0-4 severity rating. Concepts for a new form were brainstormed and evaluated using a variation of a Pugh chart. From the concepts, sketches were created using form design guidelines and were evaluated using Nielsen’s heuristics. Usability problems from the heuristic evaluation were solved and the sketches were translated into a computer prototype which was subsequently usability tested using a mixed methods approach with 6 users. Task completion increased, total time on task decreased significantly, and PSSUQ and SUS increased. Taken together with the qualitative results, the usability of the new prototype was higher than the current system. Important qualities that increase the usability in forms for publishing academic student papers included a wizard structure, explaining terminology and focus on guiding the user. Further studies should include usability studies of other publication types and further validating guidelines for form design. / Studenter upplever problem när de ska publicera sina examensarbeten i det nationella Digitala Vetenskapliga Arkivet (DiVA). Det nuvarande formuläret testades med 7 användare i ett användbarhetstest med Tänka-högt protokoll och det visades att användbarheten var låg. De tre aspekterna av användbarhet representerades av följande kvalitativa mått: efficiency representerades av tid för uppgiften, effectiveness representerades av task completion och satisfaction representerades av PSSUQ och SUS. 22 användbarhetsproblem hittades och prioriterades med en allvarlighetsgrad mellan 0-4. Nya koncept togs fram och utvärderades med en variation av en Pugh-matris. Från koncepten skapades skisser i enlighet med tumregler för formulärsdesign och utvärderades med Nielsens tumregler. Problem som identifierades i DiVA löstes och en datorprototyp skapades varpå den testades med samma metod som det nuvarande formuläret med 6 användare. Task completion ökade, tiden för att lösa uppgiften minskade signifikant och PSSUQ och SUS minskade signifikant. Tillsammans med de kvantitativa resultaten är slutsatsen att användbarheten var högre i prototypen än i det nuvarande systemet. Kvaliteter som ökar användbarheten i formulär som används för att publicera akademiska studentarbeten är en stegvis struktur, förklarande av terminologi och fokus på att vägleda användaren. Framtida studier bör inkludera användbarhetstest för andra publikationstyper och validering av tumregler för formulärsdesign.
