An Augmented Reality Android Application For Interaction with Sound Zones

Abstract

Dette projekt sigter mod at give et middel til interaktion med lydzoner gennem Augmented Reality (AR). For at realisere denne opgave er der udviklet en Android-mobilapplikation. Det underliggende problem forbundet med interaktion med lydzone er blevet fastslået til at være den skjulte overkommelighed for lydzonerne. For at løse dette problem er det blevet foreslået at bruge AR til at oprette lydzone visualisatorer med en mulighed for brugerinteraktion. Der er gennemført en undersøgelse af interaktionsmetoderne med AR, hvor berøringsskærmbevægelser er etableret som et redskab til at nå interaktionsmålet. Denne rapport giver en grundig beskrivelse af designprocessen, som uddyber designvalgene gennem udvikling. Mulighederne for brugerinteraktion er skitseret, og der er etableret et sæt krav. Flere kandidater til lydzonevisualiseringer er oprettet via GV Design Sprint-metoden, hvor de nøjagtige funktioner og egenskaber ved den foreslåede løsning er beskrevet. Designsprinten resulterede i 3 visualiseringskoncepter og 4 forskellige former, som lydzoner kunne tage. Implementeringsdelen af denne rapport har grundigt beskrevet systemets arkitektur sammen med brugen af ARCore og Sceneform til implementering af AR-interaktion. Anvendeligheden af applikationen og de designede visualiseringer er testet, hvor feedback fra testdeltagere er blevet implementeret i den anden iteration af implementeringen. Baseret på resultaterne kan det konkluderes, at den udviklede applikation muliggør interaktion med lydzoner gennem AR.

This project aims to provide a mean of interaction with sound zones through Augmented Reality (AR). To realise this task an Android mobile application has been developed. The underlying problem associated with the sound zone interaction has been established to be the hidden affordance of the sound zones. To address this problem it has been suggested to utilise AR to create the sound zone visualisers with an option for user interaction. A research into the interaction methods with AR has been conducted, where touch-screen gestures have been established as a tool to achieve the interaction goal. This report provides a thorough description of the Design process which elaborates on the design choices through development. The user interaction options have been outlined and a set of requirements has been established. Several candidates for the sound zone visualisations have been created via the GV Design Sprint method, where the exact features and properties of the proposed solution have been described. The design sprint resulted in 3 visualisation concepts and 4 different shapes the sound zones could take on. The Implementation part of this report has thoroughly described the architecture of the system along with the usage of ARCore and Sceneform to implement AR interaction. The usability of the application and the designed visualisations has been tested, where test participant feedback has been implemented in the second iteration of implementation. Based on the results it can be concluded that the developed application allows for interaction with sound zones through AR.
