Prestanda av användargränssnitt i cross-platform-appar

Syftet med denna studie är att undersöka fördröjningsskillnader inom användargränssnitt mellan native­utvecklade appar (utveckling till varje plattform) och appar av typen generated apps. Eftersom arbetet syftar till att bidra med information om prestanda ansågs en experimentell metod vara det bästa valet. Mätning av laddningstider gjordes med hjälp av en videokamera som filmade utförandet av experimenten vilket gjorde metoden simpel och liknar det som en användare kommer att uppleva. Avgränsning till plattformarna Android och iOS gjordes där Xamarin valdes som ramverk inom tekniker som skapar generated apps. Mätdata från experiment som undersökte laddningstider, experiment med användare som hanterade listors respons samt undersökning av CPU­ och minnesanvändning tyder på ett återkommande mönster. Xamarin Forms med XAML är den teknik som presterat sämst under experimenten som sedan följs av Xamarin Forms. Xamarin Android/iOS hade inte lika stora prestandaförluster jämfört med native­utvecklade delar. Generellt hanterar Xamarin Forms telefonens resurser sämre än vad Xamarin Android/iOS och native gör. Resultat från studien kan användas som beslutsstöd vid val av teknik. Studien bidrar även med data som kan användas vid vidare forskning inom området.

Towards automated Android app collusion detection

Android OS supports multiple communication methods between apps. This opens the possibility to carry out threats in a collaborative fashion, c.f. the Soundcomber example from 2011. In this paper we provide a concise definition of collusion and report on a number of automated detection approaches, developed in co-operation with Intel Security.

App mobile con l'integrazione di social network e google api per migliorare l'esperienza utente

Questa tesi esamina la progettazione e lo sviluppo di un'applicazione mobile Android che è in grado di gestire l'attività sportiva di un utente. L'applicazione offre numerose funzionalità, che permettono all'utente di eseguire allenamenti per il fitness e allenamenti per la corsa, tenendo sempre sotto controllo i risultati ottenuti e tutte le informazioni necessarie. Oltre ad eseguire allenamenti l'utente può crearne di propri e modificarli a suo piacimento, in più nell'App è inserito lo shop dove l'utilizzatore può comprare allenamenti messi a disposizione direttamente da FitBody. Gli aspetti visti sopra saranno descritti attraverso un'analisi del problema e un'analisi sulla progettazione architetturale. In particolare verranno sottolineati aspetti riguardanti l'interazione tra utenti e l'utilizzo di API che permetteranno all'utilizzatore di condividere le proprie esperienze sul social network Facebook e di avere un'esperienza completa con l'app. In questo scritto si parlerà anche della comunicazione tra applicazione e server, che avviene grazie a chiamate HTTP con metodo POST. Attraverso queste chiamate l'applicazione leggerà e scriverà informazioni sul database online, 'hostato' sulla piattaforma Altervista. L'applicazione web, di cui sarà data solamente un'infarinatura, è stata sviluppata utilizzando il linguaggio di programmazione PHP. Ogni 'response' inviata dal server al client è composta da uno o più oggetti JSON.

Development of Mobile Web App "ESP" for DeepBlue to interrogate how an audience is thinking

DeepBlue is much more than just an orchestra. Their innovative approach to audience engagement led it to develop ESP, their Electronic Show Programme web app which allows for real-time (synchronous) and delayed (asynchronous) audience interaction, customer feedback and research. The show itself is driven invisibly by a music technology operating system (currently QUT's Yodel) that allows them to adapt to a wide range of performance venues and varied types of presentation. DeepBlue's community engagement program has enabled over 5,500 young musicians and community choristers to participate in professional productions, it is also a cornerstone of DeepBlue's successful business model. You can view the ESP mobile web app at m.deepblue.net.au if you view this and only the landing page is active, there is not a show taking place or imminent. ESP prototype has already been used for 18 months. Imagine knowing what your audience really thinks – in real time so you can track their feelings and thoughts through the show. This tool has been developed and used by the performing group DeepBlue since late 2012 in Australia and Asia (even translated into Vietnamese). It has mostly superseded DeepBlue's SMS realtime communication during a show. It enables an event presenter or performance group to take the pulse of an audience through a series of targeted questions that can be anonymous or attributed. This will help build better, long-lasting, and more meaningful relationships with groups and individuals in the community. This can take place on a tablet, mobile phone or future platforms. There are three organisations trialling it so far.

Dressing up Tinderella: Interrogating authenticity claims on the mobile dating app Tinder

Mobile dating applications (‘apps’) have increased in popularity over recent years, with Tinder among the first to break into the mainstream heterosexual market. Since mobile dating intensifies the need to confirm that potential dates are not misrepresenting themselves and are safe to meet in person, Tinder’s success indicates that it has allayed these concerns regarding the authenticity of its users. This article combines Giddens’ conceptualization of authenticity, as the ability to reference a coherent biographical narrative, with Callon’s sociology of translation to investigate Tinder’s framing of authenticity within mobile dating. Applying a walkthrough method that interrogates Tinder’s technological architecture, promotional materials, and related media, this hybrid theoretical framework is used to identify how Tinder configures an actor-network that establishes its app as the solution to users’ concerns, enrols individuals in using its features in authenticity claims, and popularizes Tinder’s framing across public discourse. This network of human and non-human actors frames authenticity as being established through one’s Facebook profile and adherence to normative standards relating to age, gender, ethnicity, and socioeconomic status. However, user discourses on other social media identify and challenge negative outcomes of this framing, with normativity fostering discrimination and Facebook verification failing to prevent abusive behavior. This case study of Tinder paves the way for future investigation into user responses to its framing. Further, it demonstrates the efficacy and broader applicability of this theoretical approach for identifying both human and technological influences on the construction of authenticity with digital media.

Mobile Dating and Hookup App Culture

This chapter surveys the landscape of mobile dating and hookup apps—understood as media technologies, as businesses, and as sites of social practice. It situates the discussion within the broader contexts of technologically mediated dating and digital sexual cultures. By outlining a number of methodological approaches and data sources that can be used in the study of dating and hookup apps, it equips the reader with tools and approaches for investigating hookup app culture in ways that go beyond “media panics” – the familiar combination of moral panics and media effects which is so prevalent in discussions of sexuality in digital media.

Random security scheme selection for mobile transactions

Security in a mobile communication environment is always a matter for concern, even after deploying many security techniques at device, network, and application levels. The end-to-end security for mobile applications can be made robust by developing dynamic schemes at application level which makes use of the existing security techniques varying in terms of space, time, and attacks complexities. In this paper we present a security techniques selection scheme for mobile transactions, called the Transactions-Based Security Scheme (TBSS). The TBSS uses intelligence to study, and analyzes the security implications of transactions under execution based on certain criterion such as user behaviors, transaction sensitivity levels, and credibility factors computed over the previous transactions by the users, network vulnerability, and device characteristics. The TBSS identifies a suitable level of security techniques from the repository, which consists of symmetric, and asymmetric types of security algorithms arranged in three complexity levels, covering various encryption/decryption techniques, digital signature schemes, andhashing techniques. From this identified level, one of the techniques is deployed randomly. The results shows that, there is a considerable reduction in security cost compared to static schemes, which employ pre-fixed security techniques to secure the transactions data.
