Utforskande av estetiska egenskaper i skalförändrade spelbräden genom samarbete mellan människa och AI (Swedish)
Abstract [en]

The primary objective is to explore the scalability of two-dimensional game maps while preserving certain aesthetical qualities in scaled representations. By either upscaling or downscaling the maps, features of the map inducing these aesthetical qualities may diminish. For instance, there could be alterations in the layout of corridors, rooms, characters, and treasures, as well as variations in the quantity of them. To address this, AI technology has been used as a means of preserving the feature soriginally introduced by the designer to create an alternatively scaled representation. The explorationis made possible by utilizing a game designer tool, Evolutionary Dungeon Designer (EDD), to designmaps - scale them - and generate AI-based solutions through an evolutionary algorithm. Furthermore, evaluations through both a user study and a controlled experiment were performed to analyze thescalability of game maps and the AI-generated representations. The user study showed some divisive results regarding whether the scaled or the AI-generated maps were superior. Often the AI-scaled maps were regarded as dissimilar compared to the original map. However, the AI could to some extent provide the same prevalence of some of the wanted features, but in a different design. This was also evident in the controlled experiment, where the AI managed to contain a specific feature to the same degree, but lacked the capability of making the maps similar.

Abstract [sv]

Det primära målet är att utforska skalbarheten hos tvådimensionella spelkartor samtidigt som vissa estetiska egenskaper bevaras i skalförändrade representationer. Genom antingen att förstora eller förminska kartorna kan vissa egenskaper som bidrar till dessa estetiska egenskaper minska. Till exempel kan det finnas förändringar i layouten av korridorer, rum, karaktärer och skatter, liksom variationer i deras antal. För att lösa detta har AI-teknologi använts för att försöka bevara de egenskaper som ursprungligen infördes av designer, genom att skapa alternativt skalförändrade representationer. Utforskningen möjliggörs genom att använda ett speldesignverktyg, Evolutionary Dungeon Designer (EDD), för att designa kartor - skalförändra dem - och generera AI-baserade lösningar genom en evolutionär algoritm. För att analysera skalbarheten hos spelkartor och de AI-genererade representationerna genomfördes utvärderingar genom både en användarstudie och ett kontrollerat experiment. Användarstudien visade delade resultat gällande om skalförändrade kartorna eller AI-skalförändrade kartorna var mest representativ. Ofta ansågs AI-skalförändrade kartor vara olika den ursprungliga kartan. I de AI-skalade kartorna fanns det dock i viss utsträckning en liknande förekomst av de valda egenskaperna, men i en annan design. Detta var också tydligt i det kontrollerade experimentet, där AI skapade kartor som hade samma grad av en specifik egenskap, men saknade förmågan att göra kartorna lika ursprungskartan.
