Based on prior research on concepts such as kinesonic feedback, and the here presented concept of kinesonic perspective, this study investigates whether or not players prefer binaurally recorded Foley over monophonically recorded Foley in a first-person video game environment, and whether or not binaural Foley has an impact on their relationship to, or perception of, the avatar. A game environment was created, in which players could switch at will between two audio modes; one containing binaurally recorded Foley, and the other containing monophonically recorded Foley. In the study, subjects were asked to state their preference between the two modes, motivate said preference, rate the two modes on three attributes, and answer questions regarding their perceived relationship to the avatar. Results showed no statistical significance regarding the preference of the sample, but a potential link was found between subjects’ preference and their perceived believability of the Foley sounds. The qualitative results showed that the binaural Foley had a complex impact on the subjects’ perception of and relationship to the avatar. The qualitative data also showed that subjects generally felt that the binaural Foley originated from their own body. Due to the small sample size and diversity of subject opinions it is however difficult to make any generalizations regarding the average player. Further research could investigate what role sound plays in the player’s ability to embody the avatar, as well as more thoroughly investigate the complex relationship between the kinesonic perspective of the avatar and that of the player.

Landstinget Blekinge är en av Blekinge Läns största fastighetsägare och har idag ett stort elbehov på grund av sin energiintensiva verksamhet. I enlighet med organisationens miljöplan finns önskemål om att utreda möjligheterna att producera egen el med solceller. Denna utredning har som syfte att analysera egenproducerad solel utifrån lönsamhet och långsiktig hållbarhet.Rapporten utgår från att beskriva potential och ekonomiska förutsättningar för installation och drift av solcellsanläggningar i Sverige, framtida energisystem, samt hur en installation skulle förändra förutsättningarna för den dagliga verksamheten för Landstinget utifrån underhåll och säkerhet. Därefter presenteras en teoretisk projektering som resulterade i två olika solcellsanläggningar för att påvisa eventuell lönsamhet, kostnad för producerad el och en uppskattad årsproduktion i förhållande till Landstingets årliga elbehov. För att genomföra en adekvat projektering och få kunskap gällande underhåll och säkerhet genomfördes intervjuer med sakkunniga och företag som investerat i solcellsanläggningar. Resultatet presenteras som två olika anläggningar vilka skiljer sig åt map storlek och montering. Placeringsalternativ A) har en installerad toppeffekt på 101 kW med en investeringskostnad på 1 100 00 – 1 260 000 kr och placeringsalternativ B) en installerad toppeffekt på 145 kW till en kostnad av 1 500 000 – 1 740 000 kr. Trots dessa skillnader blev divergensen i återbetalningstid och kostnad för producerad el marginell, både med och utan solcellsstöd. Lönsamheten är mest fördelaktig vid ett beviljat solcellsstöd och ger större ekonomisk hållbarhet med en återbetalningstid på 9,8 – 11,3 år för placeringsalternativ A) och 10 – 11,5 år för placeringsalternativ B). I förhållande till en livslängd för anläggningarna på 25 – 30 år är det en lönsam investering.Med en större årsproduktion och lättare montering i förhållande till vindlast drogs en slutsats om att anläggningen på 145 kW skulle gynna Landstinget mest både ur ett ekonomiskt och hållbart perspektiv. Det genom att anläggningen efter återbetalningstiden genererar en högre kostnadsbesparing, samt resulterar i en större minskning av av koldioxidutsläpp till följd av en av högre årsproduktion. Flera källor visar att solceller är en del av ett framtida energisystem och långsiktigt hållbart pga fördelar gentemot minskade utsläpp av växthusgaser. Genom en eventuell investering i solceller kan Landstinget Blekinge stärka och utveckla ett grönt varumärke med en förnybar energiförsöjning i form av en solcellanläggning som bidrar till hållbar utveckling i enlighet med organisationes miljöplan, samt nationella och europeiska klimat- och miljömål. / The County Council of Blekinge is one of the county’s largest property owner and has today a great need of external distribution och electricity due to the organization’s energy intensive operations. According to the County Council’s environmental plan there is a desire to investigate the possibilities of producing electricity with solar cells. Therefore this feasibility study has the purpose of analyzing its profitability anf long-term sustainability following a possible future investment.The report proceeds to describe potential and economic prerequisites for solar cells in Sweden, future energy systems, as well as changing conditions for the daily operations regarding maintenance and safety with a solar cell plant. Thereafter, with the use of a theoretical projection of a solarplant that resulted in two different, the study determines possible profitability, cost of produced electricity and an estimated yearly production relative to the County Council’s need of external electricity. To perform an adequate projection and receive knowledge about maintenance and safety interviews with special advisers and organizations which have invested in solar cell plants interviews was performed. The result is presented as two solar plants that differs in size and mounting. Alternative A) has an installed power of 101 kW with a cost of investment of 1 100 00 – 1 260 000 SEK, and alternative B) har an installed power of 145 kW to the cost of 1 500 000 – 1 740 000 SEK. Despite the differences was the disparity in pay-back-time and cost of produced electricity fractional, with our without subsidies. The profitability is the most benefitial with an issued subsidy for solar cells and implicates a shorter pay-back-period of 9,8 – 11,3 years for alternative A) and 10 – 11,5 years for alternative B). Relative to the economic lifespan of a solar plant of 25 – 30 years it is a profitable investment.With a higher estimated yearly production and easier mounting considering wind load a conclusion was drawn that alternative B) with an installed power 145 kW would benefit the County Council the most from an economic and sustainable perspective. Because after the pay-back-period has ended it would generate more savings of money and a greater lowering of carbon dioxide emissions as a result of the higher annual production of electricity. Several sources show that solar cells are a aprt of a future energy system and is long-term sustainable due to benefits considering lowered carbon dioxide emissions. At an investment the County Council of Blekinge could strengthen and develop a green brand with a renewable energy supply with a solar cell plant which would contribute to sustainable development according to the organization’s environmental plan, as well as national and European climate and environmental goals.

Based on previous research on spatial attributes in foley and the concept that auditory immersion in first-person perspective computer games is enhanced by believable sound effects, this study explores if there is a connection between stereo foley and the believability of the first-person perspective, and regardless, if there is a preference to either mono or stereo foley. An interactive listening test was created in unreal engine 4, where 20 subjects, all considered gamers, played three levels that differed visually and in auditory content. In these levels, subjects auditioned two versions of avatar-related foley sounds. One version was mono, the other stereo. The test prompted the subjects to complete two tasks for each level, whereupon the foley version changed upon completion of the first task. The subjects then answered questions in between each level, regarding the foley version. They were asked to rate believability and choose a preference, as well as provide motivations for their choices. The quantitative data showed next no evidence that either mono or stereo was generally perceived as more believable or preferred. However, the qualitative data indicates that the majority of players tend to prefer and rate stereo foley as more believable in certain game environments. Furthermore, the data indicates that some subjects prefer a sensory replication of reality in foley. It is also shown that preference for stereo width vary between subjects and therefore argued that there cannot be a perfect standardized setting for stereo foley.
