Mobila enheter så som mobiltelefoner och surfplattor är idag väldigt vanliga i arbetslivet, där de inte bara används för kommunikation utan även för att utföra arbetsuppgifter. Alla verktyg finns dock inte alltid tillgängliga för sådana enheter eller i alla fall inte i en form som gör det praktiskt att använda dem. Systemet Semko Instrument Register (SIR), utvecklat av Triona, är ett sådant verktyg i form av en ej mobilanpassad hemsida, som bland annat används för att hämta kalibreringscertifikat för mätinstrument. Målet med detta projekt är att komma fram till ett sätt att tillgängliggöra systemet på så många olika typer av mobila enheter som möjligt, på ett så enkelt sätt som möjligt. Olika metoder (mobilanpassade webbsidor, plattformsspecifika applikationer och plattformsoberoende applikationer) jämförs och analyseras, med fokus på möjligheter till att använda samma kod på flera plattformar samtidigt och huruvida de kan uppfylla kraven som är ställda på applikationen eller ej. Designförslaget tar upp ett sådant sätt, som sedan utvärderas med hjälp av olika aspekter, exempelvis mängd kod som kan återanvändas på flera plattformar. Slutsatsen är att det bästa sättet att tillgängliggöra en tjänst på så många plattformar som möjligt är genom mobilanpassade webbsidor, men på grund av de krav som ställts på projektet användes istället Ionic, ett webbteknologi-baserat verktyg för plattformsoberoende applikationsutveckling, då moderna webbläsare ej ännu har den funktionalitet som krävdes. / Mobile devices such as smartphones and tablets are very common at companies nowadays, where they’re not just used for communication but also for doing work. Not all tools are available for such devices though, or at least not in a suitable form that makes it practical to use them. Semko Instrument Register (SIR) is a such a system, developed by Triona, in the form of a website that is not adapted for mobile devices, which is used for downloading calibration certificates for measuring instruments among other things. The goal of this project is to come up with a method of making the system available to as many mobile devices as possible in the simplest way possible. Different methods (websites adapted for mobile devices, native applications and cross-platform applications) are compared and analysed with a focus on possibilities for sharing code on multiple platforms and whether they’re able to fulfill what is required of the application. The design chapter presents such a method which is then evaluated on different aspects, such as the amount of code that can be shared between platforms. The conclusion is that the best way of making a system available on multiple platforms is through websites adapted for mobile devices, but because of this particular system’s requirements a cross-platform solution called Ionic was used instead, as modern mobile browsers are not yet able to fulfill what was required of the application.

De senaste åren har marknaden för surfplattor växt massivt samtidigt som Smart-TV’s har kommit fram som en ny produktkategori. Detta arbete är en undersökningen i hur surfplattor tillsammans med Smart-TV kan användas för att skapa en bättre upplevelse för användaren. För detta utvecklades en applikation på en LG Smart TV som sammankopplades med en surfplatta för att visa information om ett pokerspel. Sedan utfördes en undersökning med intervjuer där hybridapplikationen jämfördes gentemot att bara spela på surfplattan. Resultatet visade att denna typ av applikationer har potential att fungera som ett bra komplement till att bara visa information på surfplattan i vissa situationer, men mer forskning inom området krävs. / In recent years the market for tablet has grown massively, while a new type of Television device called Smart TV has started to find its way into people’s homes. This study is dedicated to finding out if tablets can be used together with Smart TV’s in a single application to craft a better user experience. To enable this study, a poker application combining LG Smart TV with an Android tablet were created, where the TV was used as a way to show information on a much larger screen. The study used research interviews as a tool to compare this application to a similar application running on the tablet alone. The results points to this type of application having potential when designed properly, but that more research in the area is needed.

Neste trabalho foi feita uma investigação sobre a realização de processamento de áudio digital em tempo real utilizando três dispositivos com características computacionais fundamentalmente distintas porém bastante acessíveis em termos de custo e disponibilidade de tecnologia: Arduino, GPU e Android. Arduino é um dispositivo com licenças de hardware e software abertas, baseado em um microcontrolador com baixo poder de processamento, muito utilizado como plataforma educativa e artística para computações de controle e interface com outros dispositivos. GPU é uma arquitetura de placas de vídeo com foco no processamento paralelo, que tem motivado o estudo de modelos de programação específicos para sua utilização como dispositivo de processamento de propósito geral. Android é um sistema operacional para dispositivos móveis baseado no kernel do Linux, que permite o desenvolvimento de aplicativos utilizando linguagem de alto nível e possibilita o uso da infraestrutura de sensores, conectividade e mobilidade disponível nos aparelhos. Buscamos sistematizar as limitações e possibilidades de cada plataforma através da implementação de técnicas de processamento de áudio digital em tempo real e da análise da intensidade computacional em cada ambiente. / This dissertation describes an investigation about real time audio signal processing using three platforms with fundamentally distinct computational characteristics, but which are highly available in terms of cost and technology: Arduino, GPU boards and Android devices. Arduino is a device with open hardware and software licences, based on a microcontroller with low processing power, largely used as educational and artistic platform for control computations and interfacing with other devices. GPU is a video card architecture focusing on parallel processing, which has motivated the study of specific programming models for its use as a general purpose processing device. Android is an operating system for mobile devices based on the Linux kernel, which allows the development of applications using high level language and allows the use of sensors, connectivity and mobile infrastructures available on devices. We search to systematize the limitations and possibilities of each platform through the implementation of real time digital audio processing techinques and the analysis of computational intensity in each environment.
