AR-park f��r Android : Augmented Reality park i Sundsvall

M��let med detta projekt ��r att ta fram en applikationsprototyp f��r Androidenheter som ska locka anv��ndare av applikationen till och tillbaka till broparken i Sk��nsberg med hj��lp av augmented-reality. Applikationen ska k��nna av om anv��ndaren befinner sig inom eller utanf��r parkens omr��de och visa olika bilder/modeller p�� specifika GPS-koordinater i det digitala lagret beroende p�� anv��ndarens positionering. Arbetet har genomf��rts i samarbete med Dohi p�� uppdrag av Sundsvalls kommun d��r regelbundna m��ten hafts med uppdragsgivaren. Utvecklingen av applikationen sker i PhoneGap med Wikitude-plugin. Projektet har resulterat i en applikationsprototyp som anv��nder ActionRanges, som ��r en typ av GeoFence, f��r att presentera olika bilder h��mtade fr��n en egen server i det digitala lagret beroende p�� anv��ndarens position. Anv��ndarna har inom parkens omr��de m��jlighet att sj��lv p��verka de bilder som visas i det digitala lagret genom att i applikationen ta en bild som laddas upp till servern d��r bilderna lagras och d��r bilden som tagits ��ven visar det digitala lagret.

JChord : An Android application helping people learn guitar chords

Nowadays, a lot of interesting and useful and imaginative applications are springing to Android software market. And for guitar fans, some related apps bring great connivence to them, like a guitar tuner can save people from carrying a entity tuner all the time, some apps can simulate a real guitar, and some apps provide some simple lessons allowing people to learn some basic things. But these apps which can teach people, they can't really ���monitor ��� people, that is, they just give some instructions and hope people would follow them. So my project is to design an app which can detect if users are playing wrong and right real-timely. Guitar chords are always the first for new guitar beginners to learn, and a chord is a set of notes combined together in a regulated way ( get from the music theory having millions of developing ), and 'pitch' is the term for determining if the note different from other notes or noise, so the problem here is to manage the multi-pitch analysis in real time. And it's necessary to know some basics of digital signal processing ( DSP ) because digital signals are always more convenient for computers to analyze compared to analog signals. Then I found an audio processing Java library ��� TarsosDSP, and try to apply it to my Android project.
