Automating The User Interface Implementation Process by Code Generation

3G-radioverkon asetusten hallinnointi suoritetaan säätämällä radioverkkotietokantaan talletettavia parametreja. Hallinnointiohjelmistossa tuhannetradioverkon parametrit näkyvät käyttöliittymäkomponentteina, joita ohjelmiston kehityskaaressa jatkuvasti lisätään, muutetaan ja poistetaan asiakkaan tarpeidenmukaan. Parametrien lisäämisen toteutusprosessi on ohjelmistokehittäjälle työlästä ja mekaanista. Diplomityön tavoitteeksi asetettiin kehittää koodigeneraattori, joka luo kaiken toteutusprosessissa tuotetun koodin automaattisesti niistä määrittelyistä, jotka ovat nykyäänkin saatavilla. Työssä kehitetty generaattori nopeuttaa ohjelmoijan työtä eliminoimalla yhden aikaa vievän ja mekaanisen työvaiheen. Seurauksena saadaan yhtenäisempää ohjelmistokoodia ja säästetään yrityksen ohjelmistotuotannon kuluissa, kun ohjelmoijan taito voidaan keskittää vaativimpiin tehtäviin.

Desenvolupament d'una aplicació mòbil en Android per a una botiga de menjar preparat

El tema del projecte va sorgir arran de la problemàtica que els va sorgir a uns amics que van muntar un negoci de menjars preparats. Per augmentar la clientela i donar un valor afegit i diferenciat al seu negoci, va sorgir la idea de muntar un app perquè els clients poguessin consultar els plats disponibles i fer una comanda d’allò què volien aquell dia, i un cop estigués llesta la comanda, els arribés una notificació al mòbil. D'aquesta manera no els caldria estar esperant a la botiga fins que la seva comanda estigués preparada. La idea seria millorar l’eficiència en l’atenció al client i la preparació de comandes.

Co-created Mobile Narratives

FM Marjo Mäenpään Turun yliopiston Humanistisen tiedekunnan Kulttuurituotannon ja maisemantutkimuksen digitaalisen kulttuurin oppialalle valmistunut väitöskirja Co-created Mobile Narratives tarkastetaan Porin yliopistokeskuksessa 27. huhtikuuta 2013. Marjo Mäenpää tutkii, kuinka ihmiset tarinallistavat elämänsä, kuvittavat ja jakavat kokemuksiaan toisten ihmisten kanssa mobiilin median avulla. Elämänjulkaisemisesta on tullut ihmisten arkista toimintaa. Mäenpää lähestyy jaettuja kännykkävideotarinoita kolmesta eri näkökulmasta. Hän tutkii tarinoiden rakennetta, julkaisemista ja julkaisevia yhteisöjä narratologian, yhteisöjen toiminnan ja mediantutkimuksen valossa. Teoreetikot aina Aristoteleesta klassisen narratologian tutkijoihin ovat esittäneet erilaisia tarinallisuuden kaavoja ja rakenteita, joita on havaittavissa myös yhteisössä tuotetuista videotarinoista. Myöhemmän alan tutkimustradition, mm. kognitiivisen narratologian mukaan ihmiset hahmottavat tarinallisia kokonaisuuksia pienemmistäkin fragmenteista ja vihjeistä. Elämän tarinaa, käännekohtia ja elämyksiä kerrotaan usein – esimerkiksi Facebookissa – yksittäisillä, sattumanvaraisilla kuvilla. Yhteisöllinen tuotanto edellyttää luottamusta. Yhteisö jakaa tarinoita, jotka voivat olla hyvinkin fragmentaarisia, mutta saavat merkityksensä yhteisestä kokemusmaailmasta ja kulttuurista. Julkaiseminen on sattumanvaraista, luovaa toimintaa, jonka lopputulos voi olla ennalta arvaamaton. Kuitenkin julkaiseminen edellyttää jonkinlaista aktiivista toimijaa tai tuottajaa. Rakenteen julkaisemiselle voi antaa tuottaja, moderaattori tai hyvin rakennettu teknologinen julkaisualusta. Monitieteisen väitöstutkimuksen aineisto on peräisin Turun yliopiston, Tampereen teknillisen yliopiston ja Aalto- yliopiston Porin yksiköiden yhteisestä Mobile Social Media -tutkimushankkeesta. Vuosina 2008-2010 hankkeessa suunniteltiin MoViE (Mobile Video Experience) -sovellusta, jonka avulla ihmiset voivat julkaista omia lyhyitä videoitaan ja jakaa niitä toisten käyttäjien kanssa. MoViE-sovelluksen avulla käyttäjät voivat editoida omia ja toisten kuvaamia videoita sekä julkaista kuvallisia tarinoita yhteisöllisistä kokemuksista. MoViE-sovellusta kokeiltiin mm. Pori Jazz -konserteissa. Samasta konsertista taltioitui kännykkävideoille useita näkökulmia, ja testikäyttäjäryhmä koosti useita erilaisia videotarinoita yhteisestä konserttikokemuksestaan. Marjo Mäenpää (1959) työskentelee opetus- ja kulttuuriministeriössä kulttuuriasiainneuvoksena. Hän on toiminut mm. kustantajana, multimedian dramaturgian opettajana Teatterikorkeakoulussa, digitaalisen mediatuotannon professorina Aalto-yliopiston Taiteen ja suunnittelun korkeakoulussa vuosina 2006-2012 sekä Taiteen edistämiskeskuksen väliaikaisena johtajana vuonna 2013.

Influencing Perceived Agency: A Study into User Experiences in Digital Interactive Storytelling

User experience is a crucial element in interactive storytelling, and as such it is important to recognize the different aspects of a positive user experience in an interactive story. Towards that goal, in the first half of this thesis, we will go through the different elements that make up the user experience, with a strong focus on agency. Agency can be understood as the user’s ability to affect the story or the world in which the story is told with interesting and satisfying choices. The freedoms granted by agency are not completely compatible with traditional storytelling, and as such we will also go through some of the issues of agency-centric design philosophies and explore alternate schools of thought. The core purpose of this thesis is to determine the most important aspects of agency with regards to a positive user experience and attempt to find ways for authors to improve the overall quality of user experience in interactive stories. The latter half of this thesis deals with the research conducted on this matter. This research was carried out by analyzing data from an online survey coupled with data gathered by the interactive storytelling system specifically made for this research (Regicide). The most important aspects of this research deal with influencing perceived agency and facilitating an illusion of agency in different ways, and comparing user experiences in these different test environments. The most important findings based on this research include the importance of context-controlled and focused agency and settings in which the agency takes place and the importance of ensuring user-competency within an interactive storytelling system. Another essential conclusion to this research boils down to communication between the user and the system; the goal of influencing perceived agency should primarily be to ensure that the user is aware of all the theoretical agency they possess.

Automated UI testing. WBCT, a computer-automated user test environment tool.

Today, the user experience and usability in software application are becoming a major design issue due to the adaptation of many processes using new technologies. Therefore, the study of the user experience and usability might be included in every software development project and, thus, they should be tested to get traceable results. As a result of different testing methods to evaluate the concepts, a non-expert on the topic might have doubts on which option he/she should opt for and how to interpret the outcomes of the process. This work aims to create a process to ease the whole testing methodology based on the process created by Seffah et al. and a supporting software tool to follow the procedure of these testing methods for the user experience and usability.

Quantifying epistemic actions in human-computer interaction

As digital systems move away from traditional desktop setups, new interaction paradigms are emerging that better integrate with users’ realworld surroundings, and better support users’ individual needs. While promising, these modern interaction paradigms also present new challenges, such as a lack of paradigm-specific tools to systematically evaluate and fully understand their use. This dissertation tackles this issue by framing empirical studies of three novel digital systems in embodied cognition – an exciting new perspective in cognitive science where the body and its interactions with the physical world take a central role in human cognition. This is achieved by first, focusing the design of all these systems on a contemporary interaction paradigm that emphasizes physical interaction on tangible interaction, a contemporary interaction paradigm; and second, by comprehensively studying user performance in these systems through a set of novel performance metrics grounded on epistemic actions, a relatively well established and studied construct in the literature on embodied cognition. The first system presented in this dissertation is an augmented Four-in-a-row board game. Three different versions of the game were developed, based on three different interaction paradigms (tangible, touch and mouse), and a repeated measures study involving 36 participants measured the occurrence of three simple epistemic actions across these three interfaces. The results highlight the relevance of epistemic actions in such a task and suggest that the different interaction paradigms afford instantiation of these actions in different ways. Additionally, the tangible version of the system supports the most rapid execution of these actions, providing novel quantitative insights into the real benefits of tangible systems. The second system presented in this dissertation is a tangible tabletop scheduling application. Two studies with single and paired users provide several insights into the impact of epistemic actions on the user experience when these are performed outside of a system’s sensing boundaries. These insights are clustered by the form, size and location of ideal interface areas for such offline epistemic actions to occur, as well as how can physical tokens be designed to better support them. Finally, and based on the results obtained to this point, the last study presented in this dissertation directly addresses the lack of empirical tools to formally evaluate tangible interaction. It presents a video-coding framework grounded on a systematic literature review of 78 papers, and evaluates its value as metric through a 60 participant study performed across three different research laboratories. The results highlight the usefulness and power of epistemic actions as a performance metric for tangible systems. In sum, through the use of such novel metrics in each of the three studies presented, this dissertation provides a better understanding of the real impact and benefits of designing and developing systems that feature tangible interaction.

Gerenciamento de mobilidade transparente com suporte integrado a QoS/QoE em redes heterogêneas

Os avanços nas tecnologias de comunicação sem fio, a demanda por novas aplicações multimídia em tempo real, com requisitos de Qualidade de Serviço (QoS) e Qualidade de Experiência (QoE), e a proliferação de equipamentos móveis, originam o surgimento de soluções que permitem mobilidades horizontais e verticais em redes heterogêneas, de modo transparente. Esses dispositivos móveis apresentam múltiplas interfaces sem fio, onde os usuários se conectam para realizar tarefas e serviços variados no seu dia a dia, mediante a tecnologia de redes diferentes, proporcionando um cenário heterogêneo com diversas oportunidades de conectividade para os usuários móveis. Visando solucionar o problema de várias conexões, feitas por usuários móveis, em uma mesma rede Wi-Fi (Wireless Fidelity) e/ou WiMAX (Worldwide Interoperability for Microwave Access) com diferentes serviços executados, porém, utilizando incorretamente a rede, esta dissertação propõe uma técnica hierárquica de decisão de mobilidade transparente, baseada em uma função de custo, no padrão IEEE 802.21 e no mapeamento de classes de serviço para garantir QoS/QoE para usuários em períodos de mobilidade chamada de MIH2Q, onde essa política informa a melhor rede para ser utilizada, de acordo com o serviço utilizado pelo usuário móvel. A avaliação do impacto e os benefícios da proposta são feitas através de simulação no NS-2 (Network Simulator - version 2) e no evalvid, utilizando métricas de QoS e QoE para verificação dos resultados.

Análise de handover a partir do uso de femtocells em redes LTE: abordagem baseada em simulação discreta

O volume de tráfego de dados em redes celulares está crescendo exponencialmente. A explosão do uso de dispositivos e aplicações móveis nos últimos anos, tem levado a uma sobrecarga da infraestrutura da rede responsável pelo escoamento desse tráfego, afetando tanto o desempenho da rede quanto a experiência do usuário. Um dos elementos-chave nas redes LTE (Long Term Evolution) é a possibilidade de implantação de múltiplas femtocells para a melhoria de cobertura e taxa de dados. No entanto, as sobreposições arbitrárias na cobertura dessas células tornam a gestão do mecanismo de handover complexo e desafiador. Nesse sentido, esta dissertação propõe uma metodologia para o estudo do impacto do handover em redes LTE com femtocells. A partir de uma abordagem de simulação discreta, os efeitos da implantação de femtocells foram avaliados. Objetivou-se com isso, mensurar os impactos e a correlação do uso de femtocell nos parâmetros de QoS (Quality of Service) e indicadores de desempenho de handover.

Aplicação da tecnologia 4G em projetos de telefonia

This paper presents a study based on bibliographic research on LTE technology, chosen for the fourth generation of mobile phones, and the current status of implementation of 4G network in Brazil. The change in user behavior, which now uses data over the voice services, requires transmission networks to be increasingly robust and fast to enable the viewing of videos and use of other platforms that require internet connection. The retrospective of the development of mobile technologies, from 1G up to 4G that is currently used, shows the long road until it came to appliances and how the phone is used nowadays. Finally, the popularity of smartphones and hence the growing number of people with access to 4G networks, demanded new researchs for the development of future generations technologies in order to achieve the demand for speed enabling significant changes in user experience

Video Quality Assessments on Digital TV and Video Streaming Services Using Objective Metrics

There is a wide range of telecommunications services that transmit voice, video and data through complex transmission networks and in some cases, the service has not an acceptable quality level for the end user. In this sense the study of methods for assessing video quality and voice have a very important role. This paper presents a classification scheme, based on different criteria, of the methods and metrics that are being studied in recent years. This paper presents how the video quality is affected by degradation in the transmission channel in two kinds of services: Digital TV (ISDB-TB) due the fading in the air interface and video streaming service on an IP network due packet loss. For Digital TV tests was set up a scenario where the digital TV transmitter is connected to an RF channel emulator, where are inserted different fading models and at the end, the videos are saved in a mobile device. The tests of streaming video were performed in an isolated scenario of IP network, which are scheduled several network conditions, resulting in different qualities of video reception. The video quality assessment is performed using objective assessment methods: PSNR, SSIM and VQM. The results show how the losses in the transmission channel affects the quality of end-user experience on both services studied.

Contador de repeticiones en ejercicios

[ES] Aplicación para dispositivos móviles Android que, ayudada por acelerómetros y giroscopios, da soporte al desarrollo de actividades físicas que necesiten un plan de trabajo basado en repeticiones y rutinas de ejercicios. El App ayuda a contabilizar las repeticiones de cada ejercicio, informando al usuario mediante sonido, para que este pueda mantener un ritmo continuo. El App permite la realización de ejercicios individuales hasta alcanzar un número objetivo de repeticiones o repeticiones libres; o permite la realización de una serie de ejercicios que forman parte de una rutina de ejercicios. Es posible crear rutinas de ejercicios personalizadas, eliminar rutinas o editar rutinas ya existentes (añadiendo o eliminando ejercicios y repeticiones). El reconocimiento de movimientos para la contabilización de repeticiones se realiza usando el valor absoluto del vector de aceleración generado a partir de los datos del acelerómetro del dispositivo. Este método, aunque no permite la precisión de reconocimiento de movimientos que permitiría el modelado tridimensional de la aceleración lineal del dispositivo, permite un reconocimiento menos computacionalmente costoso, ignorando ciertos factores exteriores y sin la necesidad de entrenamiento previo de la aplicación.
